    Description / Table of Contents: Summary Bodybuilders often prefer a high protein diet to achieve maximum skeletal muscle hypertrophy. In this study the effect of a high protein diet on renal acid load and renal handling of proton excretion was studied comparing dietary intake and urinary ionograms in 37 male bodybuilders and 20 young male adults. Energy intake (+7 %), protein intake (128 vs 88 g/d/1.73 m2), and renal net acid excretion (95 vs 64 mmol/d/1.73 m2) were higher in the bodybuilders than in the controls, however, urine-pH was only slightly lower (5.83 vs 6.12). In the bodybuilders renal ammonium excretion was higher at any given value of urine pH than in the controls. In a regression analysis protein intake proved to be an independent factor modulating the ratio between urine-pH and renal ammonium excretion. The concomitant increase of renal net acid excretion and maximum renal acid excretion capacity in periods of high protein intake appears to be a highly effective response of the kidney to a specific food intake leaving a large renal surplus capacity for an additional renal acid load.
    Notes: Zusammenfassung Kraftsportler ernähren sich zur Förderung des Muskelwachstums häufig proteinreich. In dieser Studie wurde die Wirkung einer hohen Proteinzufuhr auf die renale Säurelast und die renale Säureausscheidungskapazität anhand des Vergleichs der Daten der Nährstoffzufuhr und der Harnionogramme von 37 Kraftsportlern mit hoher Proteinzufuhr und 20 jungen Erwachsenen mit normaler Proteinzufuhr (Vergleichsgruppe) untersucht. Die Kraftsportler zeigten eine höhere Energie-(+7 %) und Proteinzufuhr (128 vs 88 g/d/1.73 m2) und eine höhere renale Nettosäureausscheidung (95 vs 64 mmol/d/1.73 m2) als die Vergleichsgruppe. Die Differenz der Urin pH-Werte der beiden Gruppen war allerdings erstaunlich gering (5.83 vs 6.12). Bei den Kraftsportlern war die renale Ammoniumausscheidung bei allen Urin pH-Werten deutlich höher als bei der Vergleichsgruppe. Eine Regressions-analyse ergab, daß die Proteinzufuhr das Verhältnis von Urin pH und renaler Ammoniumausscheidung eigenständig zu beeinflussen vermag. Eine vermehrte Proteinzufuhr führt zu einer erhöhten renalen Säurelast und Nettosäureausscheidung. Die gleichzeitig auftretende Steigerung der renalen Säureausscheidungskapazität infolge einer erhöhten Ammoniumproduktion stellt einen sinnvollen Anpassungsmechanismus des Körpers an diese besondere Form der Ernährung dar, der dem Körper eine ausreichende funktionelle Reservekapazität für weitere den Säure-Basen-Haushalt belastende pathophysiologische Ereignisse erhält.

    Description / Table of Contents: Summary Studying the prophylactic effects of specific yolk antibodies against diarrhea in newborn calves, also the intestinal absorption of unspecific heterogeneous avian antibodies as well as their effects on the uptake of maternal bovine colostral antibodies (bIgG) was investigated. Two groups of newborn calves received egg powder (16 g or 8 g per day) for the first 10 days of their life beginning with the first meal. A third group was kept as a control without any egg powder in their diet. Blood samples (5 to 10 calves per sampling time) were taken from 123 calves at 6, 12, 24, 48, or 96 h postnatally. With both doses the highest chicken IgG (cIgG) levels (3.1 µg resp. 1.2 µg per ml serum) have been measured 12 h after birth. These concentrations decreased continuously to the levels of 1.1 µg resp. 0.2 µg cIgG per ml serum at 96 h postnatally. The uptake into blood at 6 h postnatally has roughly been estimated as approximately 23 % (bIgG) and 7 % resp. 6 % (cIgG) of the IgG dosages given with the first meal. The time-course (6 to 96 h) of the bIgG level in blood was quite stable, plateauing already after 6 h at a mean of 5.9 mg per ml serum. Significant differences between the bIgG levels of calves with yolk antibodies in their diet (6.2 resp. 6.1 mg bIgG per ml serum) and those of the control group (5.4 mg per ml serum) could not be observed. Obviously, the prophylactic use of egg powder in newborn calves has no negative effect on the absorption of colostral antibodies. However, with the feeding of chicken egg yolk antibodies already with the first meal also the absorption of avian antibodies has to be taken into consideration.
    Notes: Zusammenfassung Im Rahmen einer Untersuchung zur prophylaktischen Wirksamkeit von spezifischen Dotterantikörpern bei erregerbedingten Kälberdurchfällen wurde auch die Absorption der unspezifischen heterologen aviären Dotterantikörper (cIgG) und deren Wirkung auf die Aufnahme von maternalen bovinen Kolostrumantikörpern (bIgG) überprüft. Zwei Gruppen von neugeborenen Kälbern wurde sprühgetrocknetes Volleipulver ab der ersten Tränke in einer Dosierung entweder von 16 g oder von 8 g pro Tag während der ersten 10 Lebenstage verabreicht. Eine dritte Gruppe diente als Kontrolle und erhielt kein Eipulver. Von insgesamt 123 Kälbern (5 bis 10 Kälber pro Entnahmezeitpunkt) wurden 6, 12, 24, 48, 72 bzw. 96 Stunden post natum Blutproben genommen. Bei beiden Eipulverdosierungen wurden die höchsten Hühner-IgG-Konzentrationen (3,1 µg bzw. 1,2 µg pro ml Serum) jeweils 12 Stunden post natum ermittelt. Diese cIgG-Konzentrationen nahmen danach kontinuierlich auf Konzentrationen von 1,1 µg bzw. 0,2 µg pro ml Serum zum Zeitpunkt 96 Stunden post natum ab. Bezogen auf die mit der ersten Tränke verabreichte bIgG- bzw. cIgG-Menge wurde überschlagsweise zum Zeitpunkt 6te Lebensstunde eine Anflutung im Blut von 23 % (bIgG) bzw. von 7 % und 6 % (cIgG) errechnet. Der zeitliche Verlauf (6te bis 96te Stunde) der Konzentration des bovinen IgGs in den Blutproben war vergleichsweise stabil und lag durchschnittlich bei 5,9 mg pro ml Serum, wobei das Plateau bereits nach 6 Stunden erreicht war. Signifikante Unterschiede zwischen den bIgG-Werten der Kälber, die Dotterantikörper bekamen (6,2 bzw. 6,1 mg pro ml Serum), und denen der Kontrollgruppe (5,4 mg pro ml Serum) waren nicht zu beobachten. Eipulver kann somit offensichtlich zur Prophylaxe bei neugeborenen Kälbern ohne Beeinträchtigung der Absorption der kolostralen Antikörper verabreicht werden. Allerdings muß bei einer Eipulververgabe mit der ersten Tränke auch mit einer Absorption von aviären Dotterantikörpern gerechnet werden.

    Description / Table of Contents: Summary Referring to the data of the National Food Consumption Study in Germany and the Dietary and Nutritional Survey of British Adults, this article compares the food intake of German and British adults. Such a comparison is possible because both studies have mainly the same methodology. The comparison of the food intake of German and British adults points out food groups which Germans consume inhigher amounts than British people do. To this category belong meat products and sausages, eggs, cheese and cottage cheese, butter, fat for cooking and salad oil, bread and pastries, vegetables, fruit, preserves and soft drinks. The Germans consumeless meat, fish and fish products, milk and milk products, pasta, rice and miscellaneous cereals, potatoes, sugar, sweets and tea than the British people do. The consumption of fruit products, alcoholic beverages and coffee is nearly the same in Germany and Great Britain.
    Notes: Zusammenfassung Anhand der Nationalen Verzehrsstudie und des „Dietary and Nutritional Survey of British Adults“ wird der Lebensmittelverzehr der Erwachsenen in Deutschland und Großbritannien verglichen. Dies ist möglich, weil die Methodik weitgehend übereinstimmt. Beim Vergleich des Lebensmittelverzehrs von Deutschen und Briten fallen Lebensmittel auf, von denen die Deutschenmehr zu sich nehmen als die Briten. Dazu gehören Fleisch- und Wurstwaren, Eier, Käse und Quark, Butter, Speisefette und -öle, Brot und Backwaren, Gemüse, Obst, Marmelade/Konfitüre und alkoholfreie Getränke. Die Deutschen nehmen dagegenweniger Fleisch, Fisch und Fischwaren, Milch und Milchprodukte, Nährmittel, Kartoffeln, Zucker, Süßwaren und Tee zu sich als die Briten. Beim Konsum von Obstprodukten, alkoholischen Getränken und Röstkaffee herrschen nur geringfügige Unterschiede zwischen Deutschen und Briten.

    Description / Table of Contents: Summary A trial on total metabolism was conducted in eight nonpregnant, nonlactating sows over eight periods, each of 16 days duration, to measure potential fatty acid induced thermogenesis. During the first and last experimental periods, the animals received a basal ration which just covered the energy maintenance requirement. In the second to seventh periods supplements of olive oil, fish oil, or puffed wheat starch as reference nutrient were added to the diet in random sequence at two levels up to 50 % above the maintenance requirement. All rations were calculated with reference to the sows' initial weight and remained quantitatively unchanged throughout the experiment. The animals were fed twice daily. During each metabolism period a complete energy balance was assessed for all sows by means of collection technique (feed, feces, urine), and 48-h measurements of the gas exchange in a respiration chamber. The sows' body mass increased linearly during the course of the experiment by 5.8 kg per period. The three supplement types had no influence on the animals' final body weight, wich averaged 205.5 kg with the starch supplement, 204.8 kg with olive oil, and 205.8 kg with fish oil. Energy digestibility (DE/GE) was 100 % for all three supplements, and metabolizability of energy (ME/GE) one percentage point less. Carbon and energy depositions showed a pronounced linear relationship to the level of supplementation and were also influenced by the type of supplement. Heat production was 20.9 MJ/d after feeding the basal ration alone and, taking the average of the two supplementation levels, 21.6 MJ for the starch supplement, 21.0 MJ for olive oil, and 20.6 MJ for fish oil. The relationship between energy deposition and the supply of ME resulted in regression coefficients of 0.9 MJ/MJ after feeding starch and 1.0 MJ/MJ after feeding the two oils. It can be concluded from these results that supplementation of the diet with fat containing mono- or polyunsaturated fatty acids above the energetic maintenance requirement under conditions of severely restricted movement (respiration chamber) has no influence on thermogenesis and consequently causes a deposition of energy equivalent to the amount supplied with the dietary fat.
    Notes: Zusammenfassung Zur Messung einer fettsäureninduzierten Thermogenese wurde ein Gesamtstoffwechselversuch mit 8 nichtgraviden, nichtlaktierenden Sauen über 8 Perioden von jeweils 16 Tagen Dauer durchgeführt. Die Tiere erhielten in der ersten und letzten Versuchsperiode eine den energetischen Erhaltungsbedarf deckende Grundration. In Periode 2 bis 7 wurden in zufälliger Reihenfolge Olivenöl, Fischöl bzw. als Referenznährstoff Weizenquellstärke in jeweils 2 Mengenstufen bis 50 % über das Erhaltungsniveau zugelegt. Alle Rationen wurden aufgrund der Anfangsmasse der Sauen eingestellt und über den gesamten Versuch in unveränderter Menge beibehalten. Die Fütterung erfolgte zweimal täglich. Von allen Tieren wurde in jeder Stoffwechselperiode eine vollständige Bilanzmessung mit Sammeltechnik (Futter, Kot, Harn) und 48stündiger Messung des Gaswechsels in der Respirationskammer durchgeführt. Die Körpermasse der Sauen stieg im Versuchsablauf linear um 5,8 kg je Zulageperiode an. Die drei Zulagearten hatten keinen Einfluß auf die Körpermasse der Tiere, sie wogen im Mittel bei Stärkezulage 205,5 kg, bei Olivenöl und Fischöl 204,8 bzw. 205,8 kg. Die Verdaulichkeit der Energie (DE/GE) betrug bei allen drei Zulagen 100 %, die Umsetzbarkeit der Energie (ME/GE) einen Prozentpunkt weniger. Der Kohlenstoffund Energieansatz zeigte eine ausgeprägte lineare Abhängigkeit zur Zulagenhöhe sowie einen signifikanten Effekt der Zulagenart. Die Wärmebildung betrug bei alleiniger Fütterung der Grundration 20,9 MJ und im Mittel der beiden Zulagestufen bei Stärkefütterung 21,6 MJ und bei Olivenöl und Fischöl 21,0 bzw. 20,6 MJ/d. Die Abhängigkeit des Energieansatzes von der Zufuhr an ME ergab Regressionskoeffizienten von 0,9 MJ/MJ bei Verabreichung von Stärke und 1,0 MJ/MJ bei Fütterung der beiden Öle. Aus den Ergebnissen ist zu folgern, daß eine Zulage von Fetten mit einfach oder mehrfach ungesättigten Fettsäuren über dem energetischen Erhaltungsbedarf unter der Bedingung stark eingeschränkter Bewegungsaktivität (Respirationskammer) keinen Einfluß auf die Thermogenese und somit einen energetischen Ansatz entsprechend der zugeführten Energie des Nahrungsfettes bewirkt.

    Description / Table of Contents: Summary The standard food for our volunteers, prepared in the central kitchen of the University Hospital of Tuebingen, consisted of breakfast, warm lunch and cold supper and contained, on average, approximately 230 µg of iodine/day. It is generally assumed that an equilibrium is established between iodine intake from food and urinary iodine excretion. Hence, the amount of iodine excreted with the urine within 24 h may reflect the daily ingestion of iodine. The fecal iodine losses are considered negligible. The alimentary iodine supply from food of our clinic would meet the WHO recommendations of 〉150 µg/day to prevent iodine-deficiency goiters. In 27 healthy volunteers the daily uptake of iodine was determined and the urinary excretion of iodine within 24 h was measured. Unexpectedly, only 16 % to 18 % of the alimentary iodine were excreted with the urine. Hence, the utilization of iodine from the food appears to be limited and therefore cannot prevent goiters in goiter areas. In addition, it was found that the correlation between urinary excretion of iodine and urinary excretion of creatinine is not a reliable parameter for the real daily excretion of iodine and iodine balance.
    Notes: Zusammenfassung Die Verpflegung (Frühstück, Mittagessen und Abendessen) aus der Zentralküche des Universitätsklinikums in Tübingen enthält durchschnittlich 230 µg Iod/Tag. Bei Personen, die täglich an dieser Verpflegung teilnehmen, stellt sich ein Gleichgewicht zwischen Iodaufnahme und renaler Iodausscheidung ein. Die Iodausscheidung über die Faeces gilt als vernachlässigbar. Die in unserer Klinikverpflegung angebotene Iodmenge entspricht dem von der WHO geforderten Angebot von 〉150 µg Iod/Tag, um endemische Strumen zu verhindern. Bei 27 gesunden Probanden wurden die tägliche Iodaufnahme und die zugehörige Ausscheidung von Iod im 24-h-Urin ermittelt. Dabei zeigte sich überraschend, daß vom angebotenen Iod nur 16 % bis 18 % mit dem Urin ausgeschieden wurden. Das mit der Nahrung angebotene Iod steht offenbar dem Organismus nur begrenzt zur Verfügung und kann Strumen in Iodmangelgebieten nicht verhindern. Der Bezug der Uriniodausscheidung auf das Kreatinin liefert nur einen groben Parameter für die tägliche Iodausscheidung und für die Iodbilanzierung.

    Description / Table of Contents: Summary With regard to the reported knowledge concerning the health value of food in 9–10-year-old children (DGE, 1984) the question arose of whether this knowledge is also valid if pupils have to evaluate meals. Twenty-seven photos of meals (9 each of breakfast, lunch and supper) were presented to 252 children of the age groups 6–7, 9–10 and 12–13 years. By means of these photos, they were requested to organize their meals for 3 days. Subsequent to this procedure the children were asked to evaluate the meals with regard to their health value. The presented meals were classified by five experts of nutrition as more healthy, indifferent and less healthy. The results showed an improved selection of more healthy meals with increasing age. Likewise, the selection of meals for lunch and supper was better than the one for breakfast. There were no differences between boys and girls and children with and without experience of dieting. The evaluation of more healthy and less healthy meals demonstrated an improvement with increasing age. In contradiction to these results, children within all age groups showed a very low level of estimation (10 %) for indifferently classified meals and this level did not improve with increasing age. The results were discussed concerning the establishment of an appropriate education of nutrition with regard to the developmental stage and the emotional and motivational engagement of the children.
    Notes: Zusammenfassung Im Hinblick auf die relativ gute Bewertung einzelner Nahrungsmittel durch 9–10jährige Kinder (DGE, 1984) stellte sich die Frage, ob dieses Wissen gleichfalls für die Einschätzung von Mahlzeiten gilt. 252 Kinder der Altersgruppe 6–7 Jahre, 9–10 Jahre und 12–13 Jahre wurden daher 27 Fotos von Mahlzeiten (je 9mal Frühstück, Mittagessen und Abendbrot) vorgelegt. Die Kinder wurden aufgefordert, ihre Mahlzeiten auf der Basis der vorgelegten Fotos für 3 Tage zusammenzustellen. Danach wurden die Kinder befragt, wie sie die Mahlzeiten bezüglich ihres Gesundheitswertes einschätzen würden. Die vorgelegten Mahlzeiten waren von 5 Experten zuvor als „eher gesund“, „mittelmäßig gesund“ und „eher ungesund“ eingestuff worden. Die Ergebnisse weisen auf eine häufigere Auswahl „eher gesunder“ Mahlzeiten mit ansteigendem Alter hin. Die Auswahl für das Mittagessen und das Abendbrot war unter dem Aspekt des Gesundheitswertes in allen Altersstufen besser als die Auswahl für das Frühstück. Es zeigten sich keine deutlichen Unterschiede zwischen Jungen und Mädchen und Kindern mit und ohne Diäterfahrung. Die Einschätzung der „eher gesunden“ bzw. „eher ungesunden“ Mahlzeiten verbesserte sich gleichfalls mit zunehmendem Alter. Andererseits fand sich bei der Einschätzung der als „mittelmäßig gesund“ eingestuften Mahlzeiten ein recht niedriges Niveau in der richtigen Einschätzung (etwa 10 %) auf allen 3 Altersstufen. Die Ergebnisse werden im Zusammenhang mit gegenwärtigen und künftigen Maßnahmen in der Ernährungserziehung diskutiert, wobei aufgrund der Ergebnisse Entwicklung und Motivation und die emotionalen Bedürfnisse der Kinder stärker zu berücksichtigen sind.

    Description / Table of Contents: Summary Senile cataract indicates the opacity of ocular lenses occuring in old and especially in very old people. Lens proteins are extremely long-living and often show oxidative damages. Aging and smoking appear to be the greatest risk factors for the development of lens opacities. The sufficient antioxidant protection of young lenses decreases with the aging process. Consequently, the importance of other protective factors increases. Nutritional factors, particularly vitamins with antioxidant properties, may influence the development of senile cataracts in the ocular lens. Meanwhile an association between the supply with vitamin C, E and β-carotene and the risk of cataract development was demonstrated in animal studies and also in an increasing number of epidemiological studies. These epidemiological studies mainly support the hypothesis that higher vitamin intakes reduce the risk of developing cataracts in old age. The antioxidant properties of the named nutrients give a plausible explanation for the mechanism of cataractogenesis. On the basis of the present data definitive recommendation, necessary for cataract prevention can not yet be established. Some results seem to support higher recommendations. At the moment several large human intervention trials are carried out. Form these studies a further confirmation of the antioxidant hypothesis and of a dose-response-relationship are expected.
    Notes: Zusammenfassung Die senile Katarakt ist eine im Alter und besonders häufig im hohen Alter auftretende Trübung der Augenlinsen. Die extrem langlebigen Linsenproteine weisen häufig oxidationsbedingte Schädigungen auf. Altern und Rauchen erscheinen als die größten Risikofaktoren für eine Kataraktbildung. Während junge Augenlinsen in der Regel über eine ausreichende antioxidative Schutzkapazität verfügen, nimmt diese mit dem Alter ab. Damit wächst die Bedeutung anderer Schutzfaktoren. Nahrungsfaktoren, besonders Vitamine mit antioxidativen Eigenschaften, schützen möglicherweise vor einer Bildung von senilen Katarakten in den Augenlinsen. Ein Zusammenhang zwischen der Versorgung mit Vitamin C, E und β-Carotin und dem Kataraktrisiko konnte in tierexperimentellen Untersuchungen aufgezeigt und inzwischen auch in einer wachsenden Zahl epidemiologischer Studien nachgewiesen werden. Die bisher vorliegenden epidemiologischen Studien unterstützen mehrheitlich die Hypothese, daß erhöhte Vitaminaufnahmen das Risiko einer Kataraktbildung reduzieren. Die antioxidative Wirkung der genannten Nährstoffe liefert eine plausible Erklärung für den Mechanismus der Kataraktgenese. Es fehlen aber noch Studien, aus denen sich die für eine Prävention notwendigen Vitaminmengen ableiten lassen. Einige Untersuchungsergebnisse sprechen möglicherweise dafür, daß diese über den bisher geltenden Empfehlungen liegen. Zur Zeit werden verschiedene, große Interventionsstudien durchgeführt, die eine weitere Absicherung der Antioxidanshypothese und von Dosis-Wirkungsbeziehungen erwarten lassen.

    Description / Table of Contents: Zusammenfassung In zwei Universitäts-Großküchen, die für die Nahrungszubereitung jodiertes Speisesalz immer (Mensa A) oder nie (Mensa B) verwendeten, wurden 15 möglichst gleiche Mittagessen gesammelt und auf ihre Gehalte an Jodid und NaCl analysiert. Bei durchschnittlich ähnlichem Kochsalzgehalt enthielt das Essen in Mensa A im Mittel 6,1 µg I/100 g ww (8,5 µg I/g NaCl) mehr Jod als in Mensa B. Die Gesamtjodaufnahme mit einem durchschnittlichen Mittagessen in Mensa A betrug demnach 56,5±24,1 µg (Mensa B: 17,0±9,9 µg). Dem Einsatz von jodiertem Speisesalz in der Gemeinschaftsverpflegung scheint somit eine wichtigere Rolle auf dem Weg zu einer ausreichenden Jodaufnahme zuzukommen als bisher angenommen wurde.
    Notes: Summary In each of two university canteens differing in the use (canteen A) or non-use (canteen B) of iodized salt for food preparation, 15 mostly equal lunch meals were collected for iodide and NaCl analysis. With similar NaCl content, the meals of canteen A contained on average 6.1 µg I/100 g ww (8.5 µg I/g NaCl) more I than the meals of canteen B. Total I intake by consumption of an average meal of canteen A was estimated as 56.5±24.1 µg (canteen B: 17.0±9.9 µg). Consequently, the use of iodized salt in central catering seems to play a more important role in a sufficient I intake than assumed so far.

    Description / Table of Contents: Zusammenfassung Transportsysteme in der apikalen Zellmembran der Syncytiothrophoblasten der Plazenta sind für den Nährstoff-transport aus dem mütterlichen Kreislauf in den fetalen Stoffwechsel von elementarer Bedeutung für Wachstum und Entwicklung des Fötus. Die Carriersysteme für Aminosäuren limitieren dabei die Versorgung des Fötus mit essentiellen und nicht essentiellen Aminosäuren. An isolierten Bürstensaummembranvesikeln (BBMV) reifer menschlicher Placenta haben wir die Aufnahme von neutralen Aminosäuren am Beispiel von Alanin charakterisiert. Darüber hinaus wurden durch den Einsatz gruppenspezifischer Reagentien wichtige Aminosäureseitengruppen der entsprechenden Transportproteine identifiziert. Die Alaninaufnahme in die BBMV wird durch zwei sättigbare Carriersysteme mit unterschiedlichen Eigenschaften vermittelt. Neben einem elektrogenen Na+-abhängigen System, das auch Gln, meAIB und Met transportiert, existiert ein Na+-unabhängiges System, das kein meAIB, dafür aber zusätzlich Leu und Tyr transportiert. Beide Transportsysteme haben gleiche Affinitätskonstanten (Km-Werte) für Alanin (0,45±0,06 mmol/l). Das Na+-abhängige System transportiert Alanin mit einer 1:1 Stöchiometrie mit Na+-Ionen und weist eine 3fach höhere maximale Transportgeschwindigkeit auf. Durch Einsatz gruppenspezifischer Reagentien wurden freie SH-Gruppen in den beiden Carriern identifiziert, die für die Funktion von entscheidender Bedeutung sind. Durch Oxidation und Rückreduktion der SH-Gruppen konnte die Transportleistung der Carrier reversibel verändert werden. Da die modifizierenden Reagentien die SH-Gruppen auch in Gegenwart der Substrate blockierten, ist zu vermuten, daß die wichtigen SH-Gruppen nicht in der Substratbindungsstelle der Transportproteine liegen.
    Notes: Summary We have determined the kinetic characteristics of alanine transport into brush border membrane vesicles (BBMV) of human full term placenta and identified functional groups of the carrier proteins that are important for transport function. Alanine influx into BBMV was found to be mediated by two transport systems with different kinetic features and distinct substrate specificities. An uphill operating electrogenic Na+-dependent contransport system could be kinetically separated from a Na+-independent facilitated diffusion system. The Na+-dependent transporter mediates Na+-alanine cotransport with a 1:1 flux coupling ratio (Hill coefficient 1.13±0.12) and a Km for alanine of 0.45±0.06 mmol/l. Halfmaximal stimulation of Na+-dependent alanine influx was observed at a Na+ concentration (NaCl) of 51.4±1.3 mmol/l. A variety of group specific reagents were used to identify functional groups in the transport proteins. Only compounds reacting with SH-residues (NEM, DTNB, PCMBS) or NH2-groups (PITC) were found to affect Na+ dependent and Na+ independent alanine transport. The EC50 value for inhibition of alanine influx by PCMBS was 450±48 µmol/l. Chemical modifications of SH-groups by PCMBS caused a significant reduction (p〈0.005) in the Vmax for Na+-dependent alanine influx from 0.57±0.06 to 0.16±0.05 nmol·mg protein−1·10s−1 without affecting significantly the Km value. Inhibition by PCMBS was reversed by treatment of BBMV with DTT. When the substrate binding site of the transporter was protected by alanine or leucine, PCMBS still blocked transport function, indicating that the cruical SH groups are not located within the substrate binding site of the transport proteins.

    Description / Table of Contents: Summary The effect of diets containing olive-oil-fried sardines (diet 1) or sunflower-oil-fried sardines (diet 3) upon the serum cholesterolraise induced by dietary cholesterol was studied after a 4-week experiment in growing Wistar rats. Results of diet 1 were compared to those obtained in diets containing casein plus olive oil (diet 2), whereas results of diet 3 were compared to those obtained with casein plus sunflower oil (diet 4). All diets contained cholesterol and bovine bile as a cholesterol-raising agent. The hypercholesterolemic effect of dietary cholesterol in fried-sardine groups (a total cholesterol (TC) increase of 0.9 mmol/L (p〈0.05 and 0.4 mmol/L (not significant) in groups 1 and 3, respectively) was markedly lower than in groups 2 and 4 (a TC increase of 13.9 mmol/L (p〈0.01) and 18.2 mmol/L (p〈0.01), respectively). Serum triglyceride levels decreased in fried-sardine diets (p〈0.05) while they increased in casein diets (p〈0.05). HDL-cholesterol levels appear lower in diet 1 than in diet 2 (p〈0.05), but similar in diets 3 and 4. However, HDL-fraction carries in diets 1, 2, 3 and 4, 13 %, 4 %, 53 % and 5 % of TC, respectively. Results showed that fried-sardine diets exert a powerful check effect on the cholesterol-raising effect induced by dietary cholesterol.
    Notes: Zusammenfassung In Versuchen von 4 Wochen Dauer wurde der Einfluß cholesterolangereicherter Diäten, die in Olivenöl (Diät 1) oder in Sonnenblumenöl (Diät 3) gebratene Sardinen enthielten, auf die Erhöhung des Cholesterolspiegels bei wachsenden Wistar Ratten untersucht. Die Ergebnisse von Diät 1 wurden mit denen von Diät 2 (Kasein plus Olivenöl) und die Resultate von Diät 3 mit denen von Diät 4 (Kasein plus Sonnenblumenöl) verglichen. Alle Diäten enthielten Cholesterol und Rindergalle als cholesterolerhöhende Agentien. Der hypercholesterolämische Effekt war in den Diäten mit den gebratenen Sardinen (eine Erhöhung des Cholesterolspiegels (TC) von je 0.9 mmol/L (p〈0.05) und 0.4 mmol/L (nicht signifikant) in den Gruppen 1 und 3) auffallend kleiner als in den Kontrollgruppen 2 und 4 mit Kasein (eine Erhöhung des TC von je 13.9 mmol/L (p〈0.01) und 18.2 mmol/L (p〈0.05)). Die Serumtriglyceride fielen bei Aufnahme der Sardinen (p〈0.05) und stiegen bei Aufnahme der Kasein-Diäten (p〈0.05). Das HDL-Cholesterolgehalt war niedriger mit Diät 1 als mit Diät 2 (p〈0.05) aber ähnlich bei den Diäten 3 und 4. Die HDL-Fraktion betrug in den Diäten 1, 2, 3 und 4 je 13 %, 4 %, 53 % und 5 % des TC. Diese Ergebnisse zeigen, daß Diäten mit gebratenen Sardinen eine große Hemmwirkung auf den cholesterolerhöhenden Effekt des Cholesterols haben.

    Description / Table of Contents: Summary In an experiment with 72 male weanling Sprague Dawley rats the effect of varying selenium intake on parameters of thyroid hormone metabolism was investigated. The animals were divided into 6 groups. One of the groups was fed a semi-synthetic diet based on casein which was poor in selenium (38 µg/kg). The other groups were fed the same diet supplemented with Na2SO3·5H2O to achieve a selenium concentration of 50, 100, 300, 600 and 3 000 µg/kg. The experiment lasted 40 days. Different selenium intake had no effect on food intake, weight gain, hematological and selected clinical-chemical parameters. Determination of glutathione peroxidase activity and selenium concentration of serum showed a selenium deficiency in animals fed the diet not supplemented with selenium. Serum T3 concentration and hepatic type-I-deiodinase activity were decreased in the group without selenium supplementation in contrast to the groups fed diets adequate in selenium (100, 300 µg/kg). A diet supplementation of 50 µg/kg already increased hepatic type-I-deiodinase activity to levels of the groups fed diets adequate in selenium. In groups supplemented with 600 and 3 000 µg/kg diet, serum T3 concentration was reduced by half of groups fed diets adequate in selenium. Supplementation with 3 000 µg Se/kg lowered the type-I-deiodinase activity in contrast to groups fed diets adequate in selenium, but not significantly. Serum concentrations of T4 and fT4 were not changed by various selenium intake. The results of this investigation show an alteration in thyroid hormone metabolism at low selenium intake as well as at high selenium intake.
    Notes: Zusammenfassung Die Auswirkungen einer unterschiedlichen Selenversorgung auf Parameter des Stoffwechsels der Schilddrüsenhormone sollten in einem Versuch mit 72 männlichen wachsenden Sprague Dawley Ratten untersucht werden. Die Tiere wurden in 6 Gruppen eingeteilt, wovon eine Gruppe eine selenarme halbsynthetische Diät auf Caseinbasis mit einem Se-Gehalt von 38 µg/kg erhielt. Die übrigen Gruppen erhielten die selbe Diät, die durch Zulage von Na2SO3·5H2O auf Selengehalte von 50, 100, 300, 600 und 3 000 µg/kg gebracht wurde. Die Versuchsdauer betrug 40 Tage. Die unterschiedliche Zufuhr von Selen hatte keinen Einfluß auf Futteraufnahme, Entwicklung der Lebendmasse, hämatologische und ausgewählte klinisch-chemische Parameter. Ein Selenmangel bei der Gruppe, die die nicht supplementierte Basisdiät erhalten hatte, konnte anhand der Aktivität der Glutathion-Peroxidase und der Selenkonzentration im Serum diagnostiziert werden. Beide Parameter stiegen ab einer Se-Zulage von 300 µg/kg noch an, allerdings geringfügig. Die Konzentration von T3 im Serum und die Aktivität der Typ-I-Deiodase in der Leber der Gruppe ohne Selenzulage war im Vergleich zu den bedarfsgerecht (100, 300 µg/kg) versorgten Gruppen vermindert. Bereits eine Selenzulage von 50 µg/kg Diät konnte die Aktivität der Typ-I-Deiodase auf die Werte der bedarfsgerecht versorgten Gruppen mit 100 und 300 µg Selenzulage anheben. Bei den Gruppen mit 600 und 3 000 µg/kg Diät Selenzulage war die Konzentration von T3 im Serum im Vergleich zu den bedarfsgerecht versorgten Gruppen auf etwa die Hälfte reduziert. Durch die Selenzulage von 3 000 µg/kg Diät war die Aktivität der Typ-I-Deiodase gegenüber den bedarfsgerecht versorgten Gruppen vermindert, die Verminderung war jedoch nicht statistisch signifikant. Die Konzentrationen von T4 und fT4 waren durch die unterschiedliche Selenzufuhr kaum verändert. Die Untersuchung zeigt insgesamt, daß sowohl unzureichende als auch über den Bedarf hinausgehende Selenzufuhr zu Veränderungen im Stoffwechsel der Schilddrüsenhormone führt.

    Description / Table of Contents: Summary The lead and cadmium contents of 50 spices and 19 condiments were investigated by means of flameless atomic absorption spectrophotometry. Mercury contents were determined by cold vapor atomic absorption method including amalgamation. The mean concentrations of lead, cadmium, and mercury were 0.470 mg/kg, 0.080 mg/kg, and 0.005 mg/kg, respectively. By using the detected levels of these three heavy metals in model calculations only a small carry-over of lead, cadmium, and mercury in meat products by spices and condiments can be assumed.
    Notes: Zusammenfassung 50 Gewürze und 19 Gewürzzubereitungen wurden mittels flammenloser Atomabsorptionsspektrometrie auf ihren Blei- und Cadmiumgehalt sowie mittels Kaltdampftechnik und nachfolgender Amalgamierung auf ihren Quecksilbergehalt untersucht. Im Mittel wurden hierbei 0,470 mg Blei, 0,080 mg Cadmium und 0,005 mg Quecksilber pro kg Würzmittel gefunden. Anhand von Modellrechnungen wurde ein nur geringer Blei-, Cadmium- und Quecksilbereintrag über Würzmittel in die Wurstsorten Fleischwurst, Leberwurst und Mettwurst aufgezeigt.

    Description / Table of Contents: Zusammenfassung Die vorliegende Studie untersuchte die Beziehung zwischen der Taurinkonzentration in Plasma und Gesamtblut unter normalen physiologischen Bedingungen bei Menschen und bei Katzen sowie nach oraler Taurinsupplementierung beim Menschen und nach taurinfreier Fütterung bei Katzen. Beim Menschen betrug die durchschnittliche Taurinkonzentration im Plasma 44±8 µmol/L und im Gesamtblut 222±35 µmol/L. Unter diesen „physiologisch normalen“ Bedingungen bestand zwischen der Taurinkonzentration in Plasma und Gesamtblut keine Korrelation (r=0.092). Die Plasmataurinkonzentration stieg nach oraler Taurinsupplementierung beim Menschen rasch an bzw. fiel schnell nach taurinfreier Ernährung bei Katzen ab. Die Taurinkonzentration im Gesamtblut war dagegen mehr inert und änderte sich erst nach anhaltender Taurinzufuhr beim Menschen bzw. nach andauerndem Taurinmangel bei Katzen.
    Notes: Summary In the present study the relationship between plasma and whole blood taurine was examined under normal physiological circumstances in humans and cats. In addition, the effect of taurine supplementation on plasma and whole blood taurine was evaluated in humans and the depletion of taurine pools after a taurine-deprived diet was studied in cats. The normal plasma taurine concentration in humans was 44±8 µmol/L and the whole blood taurine concentration was 227±35 µmol/L. Under normal physiological conditions plasma and whole blood taurine were not correlated (r=0.092). Plasma taurine responded rapidly to dietary supplementation in humans or the taurine depletion in cats. In contrast, the whole blood taurine pool was more inert and varied only under extremes of depletion (cats) or sustained taurine supplementation.

    Description / Table of Contents: Summary Intestinal strontium absorption has been discussed recently as an indirect measure for calcium uptake. Prerequisite for the clinical use of an oral strontium test is the availability of a reliable procedure including controlled strontium supply, sample pretreatment and analysis as well as the assessment of normal values. In the present study, a group of young females (n=33; 24.0 ± 2.7 y; BMI 21.5 ± 1.9) received an oral dose of 2.27 mmol strontium in a standardized breakfast that contained 0.625 mmol calcium. Before and 220 min after the bolus serum strontium concentrations were determined by means of atomic absorption spectrophotometry (coefficient of variation: within day 4.8 %, n=10; day-to-day 9.5 %, n=8). The error of the method was 2.7 %. Calculation of the fractional strontium absorption rate considered the respective distribution volume (extracellular fluid; either estimated using body weight or determined by means of bioimpedance analysis [BIA]). Average absorption rates were 13.3 ± 3.1 % and, considering BIA measurement 13.6 ± 2.6 %, respectively. Smoking, exercise and, use of oral contraceptives showed no effects. Our oral strontium test is characterized by excellent reliability, easy handling and low costs and, thus, is suitable for routine use.
    Notes: Zusammenfassung Die Erfassung der Strontiumabsorption wird heute als indirektes Verfahren zur Beurteilung der intestinalen Calciumabsorption diskutiert. Voraussetzung für die klinische Anwendung ist ein vertrauenswürdiges Testverfahren inclusive kontrollierter Strontiumgabe, Probenaufarbeitung und -analyse sowie die Erfassung von Normalwerten. Für unsere Studien wurde ein Kollektiv junger Frauen (n=33, 24,0 ± 2,7 Jahre; BMI 21,5 ± 1,9) herangezogen. Die Probandinnen erhielten eine Bolusgabe von 2,27 mmol Strontium zusammen mit einem Standardfrühstück (ca. 0,625 mmol Calcium). Vor und 220 min nach der Bolusgabe erfolgte die Bestimmung des Serum-Strontiumgehaltes mittels Atomabsorptionsspektrometrie. Der Variationskoeffizient der Methode lag innerhalb eines Tages bei 4,8 % (n=10) und von Tag zu Tag 9,5 % (n=8). Der Fehler der Methode betrug 2,7 %. Die Berechnung der fraktionellen Strontiumabsorptionsrate erfolgte unter Berücksichtigung des entsprechenden Verteilungsraumes (Extrazellulärflüssigkeit; Schätzverfahren über Körpergewicht bzw. Bioimpedanz-Analyse [BIA]). Die Strontiumabsorptionsrate lag im Mittel bei 13,3 ± 3,1 %, unter Berücksichtigung der BIA-Werte bei 13,6 ± 2,6 %. Rauchen, sportliche Aktivität bzw. Einnahme oraler Kontrazeptiva zeigten keinen Einfluß. Das hier vorgestellte Testverfahren ist aufgrund seiner hohen Vertrauenswürdigkeit und relativ einfacher Handhabung für Routine-untersuchungen geeignet.

    Description / Table of Contents: Zusammenfassung Das aus dem Pankreas stammende Peptid Amylin (1 µg/kg) reduzierte nach intraperitonealer (IP) Injektion die kumulative Futteraufnahme bei Ratten, denen vor der Injektion das Futter für 24 h entzogen worden war bzw. bei Ratten, denen Futter ad lib. zur Verfügung stand, für bis zu 4 h. Der Effekt trat zu verschiedenen Zeitpunkten des Tag/Nacht-Zyklus (Beginn der Dunkelphase, Mitte der Dunkelphase, Beginn der Hellphase) auf. Der verzehrsreduzierende Effekt von IP verabreichtem Amylin wurde zu keinem dieser Zeitpunkte durch subdiaphragmatische Vagotomie aufgehoben. Vagotomie führte eher zu einer Verstärkung des verzehrsreduzierenden Effekts von Amylin, und zwar nach einem 24stündigen Futterentzug bei Injektion zu Beginn der Hellphase oder in der Mitte der Dunkelphase. Im Unterschied zu früheren Untersuchungen mit älteren Ratten konnte ein verzehrsreduzierender Effekt von Amylin auch bei Ratten beobachtet werden, denen vor der Injektion das Futter nicht entzogen worden war. In Ergänzung früherer Befunde zeigen also die Ergebnisse, daß der verzehrsreduzierende Effekt von IP verabreichtem Amylin zu verschiedenen Tageszeiten ausgelöst und durch subdiaphragmatische Vagotomie nicht aufgehoben werden kann.
    Notes: Summary The pancreatic peptide amylin (1 µg/kg) injected intraperitoneally reduced cumulative food intake for up to 4 h in food-deprived (24 h) and non-deprived rats at various times of the day, i.e., at dark onset, in the middle of the dark phase, and at light onset. At none of these times did subdiaphragmatic vagotomy abolish the anorectic effect of amylin. Rather, vagotomy enhanced, by unknown mechanisms, amylin's anorectic effect in food-deprived rats at light onset and in the middle of the dark phase. In contrast to previous studies with older rats, amylin's anorectic effect was also observed when injected into nondeprived rats. The findings of the present study extend previous reports in that amylin's anorectic effect, not being abolished by abdominal vagotomy after intraperitoneal injection, can be elicited at different times of the day.

    Description / Table of Contents: Summary During the last two decades, there has been an increasing movement in Germany to protect the natural environment from dangerous substances. This has renewed a growing common interest in government food control. This contribution ask the question of how this food legislation as a part of the general food and health policy in Germany came into being, and which promoting as well as inhibiting determinants in this scope could be observed. These statements are based partly on results of a project of the German National Research Council (Deutsche Forschungsgemeinschaft) in which the author investigates the change of food habits under the impact of industrialization and urbanization since the last century in a larger historical perspective and in a quantitative and qualitative manner with the help of current sources.
    Notes: Zusammenfassung Die in den letzten beiden Jahrzehnten in Deutschland angewachsene Bewegung zum Schutz der natürlichen Ressourcen und der verstärkten Reinerhaltung der Umwelt vor gefährlichen Schadstoffen hat auch die staatliche Lebensmittelüberwachung wieder stärker in den Brennpunkt des öffentlichen Interesses gerückt. Der Beitrag geht der bisher nur unzureichend behandelten Frage nach, wie diese gesetzliche Lebensmittelkontrolle als Bestandteil staatlicher Ernährungs- und Gesundheitspolitik in Deutschland entstanden ist und welche beschleunigenden und hemmenden Determinanten es dabei gegeben hat. Die Ausführungen basieren auf Teilergebnissen eines neuen Projekts der Deutschen Forschungsgemeinschaft, mit dem der Verfasser den Wandel der Nahrungsgewohnheiten unter dem Einfluß der Industrialisierung und Urbanisierung seit dem vorigen Jahrhundert erstmals im größeren historischen Zusammenhang anhand der überlieferten zeitgenössischen Quellen quantitativ wie qualitativ analysiert.

    Description / Table of Contents: Summary In 56 patients with HLP (40 with hypertriglyceridemia and mixed HLP respectively and 16 with hypercholesterolemia), changes in the lipid state and in the parameters of the antioxidative potential before and after a 4-week olive-oil phase, and after 8-, 20-and 32-week intakes of salmon-oil capsules were determined. The treatment with salmon-oil led to a decrease of triglycerides in patients with hypertriglyceridemia and mixed HLP respectively, on the other hand, it led to an increase of cholesterol in hypercholesterolemia. The increase of malondialdehyde as measure of lipid peroxidation in both patient groups underlines the necessity of a substitution of antioxidants. Further investigations are necessary before wide use of fishoil capsules can be recommended, expecially to avoid side-effects.
    Notes: Zusammenfassung Bei 56 Patienten mit HLP (40 Hypertriglyzeridämie bzw. mixed HLP und 16 mit Hypercholesterinämie) wurden Veränderungen im Lipidstatus und bei Parametern des antioxidativen Potentials vor und nach einer vierwöchigen Olivenölphase und nach 8, 20 und 32 Wochen Einnahme von Lachsölkapseln ermittelt. Die Behandlung mit Lachsöl führte bei Patienten mit Hypertriglyzeridämie/mixed HLP zu einer Senkung der Triglyzeride, dagegen bei Hypercholesterinämie zu einer Zunahme des Cholesterins. Die Erhöhung des Malondialdehyds als Maß für die Lipidperoxidation in beiden Patientengruppen unterstreicht die Notwendigkeit einer Substitution mit Antioxidantien. Vor einem breiten Einsatz von Fischölkapseln sind allerdings weitere Untersuchungen, nicht zuletzt zur Verringerung der Nebenwirkungen, erforderlich.

    Description / Table of Contents: Summary An animal model experiment was conducted with nine adult sows to study the effect of olive oil and fish oil (40 % polyunsaturated fatty acids) on thermogenesis compared to wheat starch as control. The treatments were given to each animal according to a latin square design. The basal diet (20 g DM/kg W0.75) was mainly based on barley and soybean meal, and matched 60 % of the ME requirements with all the other nutrients meeting maintenance requirements. The isoenergetic supplements amounted to 176 kJ gross energy per kg W0.75 and day. During each experimental period a complete energy balance was recorded for each animal using indirect calorimetry technique (RQ-method) as well as the carbonnitrogen-balance technique. The treatments did not influence the digestibility of the rations. Digestibility of energy and of carbon averaged 83.4 % and 83.3 %, respectively. All three supplements were nearly completly digested as calculated by the difference method. Fish oil increased urine energy and decreased CH4 production, the shifts, however, were in absolute terms very small. The mean O2 consumption was 1 002 l/d showing no significant treatment effects. CO2 production was lowered with olive oil by 10 %, and with fish oil by 13 % compared to the starch diet. The daily heat production was 20.95, 20.72, and 20.04 MJ when starch, olive oil or fish oil was given. Corrected for equal energy retention the difference of thermogenesis between olive oil and starch was −0.4 MJ/d, and between fish oil and starch −1.2 MJ/d. These differences corresponded to a relation of starch:olive oil:fish oil=1:0.95:0.86. The relation between starch and olive oil reflected exactly the theoretical expectation, calculated from the ATP regeneration by oxidation of both nutrients. When fish oil was added, the daily heat production was lower than theoretically calculated, which might be interpreted as an effect on the metabolic rate in general rather than especially on the efficiency of ATP formation from fish oil oxidation. In any case, there was no hint of a facultative thermogenesis induced by the oils.
    Notes: Zusammenfassung Mit Hilfe der kalorimetrischen Bilanztechnik wurde an 9 Sauen nach dem Schema eines lateinischen Quadrates die Wirkung von Olivenöl und Fischöl im Vergleich zu Weizenquellstärke auf die Thermogenese im Erhaltungsstoffwechsel gemessen. Die zu prüfenden Nährstoffe wurden einer Basisration (20 g TM/kg W0,75) zugelegt, die auf 60 % des energetischen Erhaltungsbedarfs an umsetzbarer Energie ausgerichtet war. Die isoenergetischen Zulagen betrugen jeweils 176 kJ Bruttoenergie/kg W0,75. Von allen Tieren wurde in jeder Stoffwechselperiode eine vollständige Energiebilanz erfaßt. Die Versuchsbehandlung hatte keinen Einfluß auf die Verdaulichkeit der Rationen. Die mittleren VQ-Werte der Gesamtration betrugen 83,4 % für Energie und 83,3 % für Kohlenstoff. Die Energieverdaulichkeit der Zulagen betrug in allen Fällen um 100 %. Fischöl erhöhte signifikant die Harnenergie und verminderte die CH4-Bildung im Vergleich zu den beiden anderen Rationen. Allerdings waren diese Veränderungen absolut gesehen nur minimal. Der Sauerstoffverbrauch betrug im Mittel 1002 l/d und zeigte keine Behandlungsdifferenzen. Die CO2-Abgabe war bei Verabreichung von Olivenöl um 10 % und bei Fischöl um 13 % signifikant niedriger. Die tägliche Wärmebildung betrug 20,95, 20,72 bzw. 20,04 MJ bei Fütterung der Rationen mit Stärke, Olivenöl bzw. Fischöl. Auf der Basis gleicher Energieretention verglichen, betrug der Unterschied in der Thermogenese zwischen Olivenöldiät und Stärkediät −0,4 MJ/d, der zwischen Fischöldiät und Stärkediät −1,2 MJ/d. Dies entsprach einer Relation von Stärke:Olivenöl:Fischöl=1:0,95:0,86. Das Verhältnis zwischen Stärke:Olivenöl widerspiegelte genau die theoretische Erwartung aufgrund der ATP-Regenerierung durch Oxidation dieser beiden Nährstoffe. Fischöl (ca. 40 % mehrfach ungesättigte Fettsäuren) wies eine tendenziell niedrigere Thermogenese als theoretisch erwartet auf, was möglicherweise auf einer entsprechenden Absenkung des Erhaltungsumsatzes beruhte. Die Ergebnisse zeigen, daß die verwendeten Öle keine fakultative Thermogenese induzierten.

    Description / Table of Contents: Zusammenfassung Ziel der Arbeit war, die relative Validität eines selbstgeführten 24-hour-recall-Fragebogens zu untersuchen, der in einer Ernährungserhebung mit 3 653 weiblichen und männlichen Erhebungsteilnehmern im Alter ab 7 Jahren eingesetzt wurde. Die Validierung wurde an einer Gruppe von 41 Männern durchgeführt. Ein 3-Tage-Protokoll diente als Referenzmethode. Der Vergleich des 24-hour-recall-Fragebogens mit dem 3-Tage-Protokoll erbrachte gute Übereinstimmung. Mittels des Wilcoxon matched-pairs ranked signs test (p〈0.05) konnten nur für die absoluten Energie- und Kohlenhydrataufnahmen sowie für die Protein-Nährstoffdichte signifikante Unterschiede nachgewiesen werden. Die prozentuale Verteilung der Energie auf die Hauptnährstoffe und Alkohol differierte um maximal 2,4 %. Der mediane prozentuale Unterschied in der absoluten Nährstoffaufnahme und der Nährstoffdichte lag zwischen −9 und 22 %. Die tägliche Nahrungsaufnahme war nur für 3 von 10 Lebensmittelgruppen signifikant verschieden. Die Spearman rank Korrelationskoeffizienten betrugen für alle Nährstoffdichten mehr als 0,35. Die höchsten Korrelationskoeffizienten um 0,60 wurden für die Alkoholund Nahrungsfaseraufnahme beobachtet. Die Ergebnisse zeigen, daß der 24-hour-recall-Fragebogen eine valide Methode zur Schätzung der medianen und mittleren Nahrungs-und Nährstoffaufnahme von großen Gruppen ist.
    Notes: Summary This study investigated the relative validity of a self-administered 24-h recall questionnaire in a dietary survey on 3 653 men and women 7 years of age and older. The validation was carried out in a group of 41 men. An estimated dietary record kept over 3 days served as reference method. Comparison of the questionnaire and the estimated 3-day record showed good agreement. The Wilcoxon matchedpairs ranked signs test (p〈0.05) demonstrated that the only differences were the crude energy and carbohydrate intake and the estimated nutrient density of protein. The estimated proportion of calories from carbohydrate, fat, protein, and alcohol differed by no more than 2.4 %. The median percentage differences in crude nutrient intakes and nutrient densities between the two assessment techniques ranged from −9 % to 22 %. The daily food intake differed significantly in only three of ten food groups. Spearman's correlation coefficients were higher than 0,35 for all density measurements. The highest correlation coefficients of about 0.60 were observed for alcohol and dietary fiber intake. It is concluded that the self-administered 24-hour recall questionnaire is a valid method for estimating the median and mean dietary intake of large groups of subjects.

    Description / Table of Contents: Summary Rainbow trouts were fed a complete diet with 12 mg vitamin K3 and supplemented with 20, 200 or 2 000 mg all-rac-α-tocopheryl-acetate/kg for 18 weeks. The ratio of the vitamin E-supplementation was 1 : 10 : 100. Fillets were minced and stored at −18 °C. Concentrations of α-tocopherol and phylloquinone and parameters of lipid peroxidation were measured after 4, 6, and 8 months of storage. The effects of α-tocopherol incorporated into fillets on storage stability were assessed by measuring free fatty acids, peroxides, malondialdehyde and lipofuscin. Mean α-tocopherol-concentrations in fillets were 1.4, 2.7 and 16.3 mg/100 g, respectively representing ratios of 1 : 2 : 12. The increase in α-tocopherol concentration resulted in a significant improvement of storage stability. The phylloquinone concentration in fillet was reduced in treatments with ≥200 mg vitamin E/kg; however, this did not affect the prothrombin time. No peroxides were detectable at any time. The concentrations of malondialdehyde significantly decreased with increasing supplementation of vitamin E. Lipofuscin concentrations were higher with low than with high vitamin E supplementation. The dose-related inhibition of lipid peroxidation became apparent in decreased concentrations of the free fatty acids in the crude fat. These results confirm the effectiveness of α-tocopherol as antioxidant in fish flesh. In this study the incorporation of α-tocopherol from dietary supplementation improved the long-term storage quality of trout fillets due to the effective inhibition of the lipid peroxidation. A measurable improvement of the storage stability was achieved with a supplementation of 200 mg vitamin E/kg feed.
    Notes: Zusammenfassung Filet von Forellen, die 18 Wochen lang ein Futter mit 12 mg Menadion/kg und mit drei im Konzentrationsverhältnis von 1 : 10 : 100 gestaffelten Dosierungen von all-rac-α-Tocopherylacetat (20, 200 und 2 000 mg/kg) erhalten hatten, wurde homogenisiert und bei −18 °C gelagert. Nach Lagerung über 4, 6 und 8 Monaten wurden die Konzentrationen an α-Tocopherol und Phyllochinon sowie von freien Fettsäuren, Peroxiden, Malondialdehyd und Lipofuszin als Parameter der Lipidperoxidation analysiert. Die mittleren α-Tocopherolgehalte betrugen 1,4; 2,7 und 16,3 mg/100 g Filet, entsprechend einem Konzentrationsverhältnis von etwa 1 : 2 : 12. Der dosisabhängige Anstieg bewirkte eine deutliche Verbesserung der Lagerstabilität. Die hohen Dosen an Vitamin E führten zu abnehmenden Gehalten an Phyllochinon im Fischmuskel, die ohne Einfluß auf die Prothrombinzeit waren. Die dosisabhängige Hemmung der enzymatisch katalysierten Fettoxidation spiegelte sich in abfallenden Gehalten an freien Fettsäuren im Rohfett wider. Peroxide waren an keinem Untersuchungstermin nachweisbar. Die Gehalte an Malondialdehyd sanken mit zunehmender Supplementierung von Vitamin E signifikant ab. Derselbe Einfluß zeigte sich bei Lipofuszin. Die Anreicherung der Filets mit α-Tocopherol nach Supplementierung des Futters begünstigte eine längerfristige Qualität bei Gefrierlagerung infolge einer effektiven Hemmung der Lipidperoxidation. Bereits mit der Dosierung von 200 mg α-Tocopherylacetat/kg Futter konnte im Vergleich zur Dosierung von 20 mg/kg eine meßbare Verbesserung der Lagerstabilität erzielt werden.

    Description / Table of Contents: Summary Several studies indicated a protective effect of fish oil on colon carcionogenesis which might be due to alterations in prostaglandin E2 synthesis of the colonic mucosa. Additional effects on fecal bile acid excretion may also play a role since especially secondary bile acids are known to act as promotors in colon cancer development. In the present study possible influences on bile acid excretion were investigated in 12 healthy volunteers whose daily diet was supplemented for 4 weeks with 11 g of fish oil (FO) and corn oil (CO) per day, respectively. Fecal bile acids were analyzed by gas-liquid-chromatography. Fecal excretion of total bile acids was not different during the periods of FO and CO-supplementation (301.9 vs. 320.3 mg/day). However, a non-significant trend to a lower daily excretion of the secondary bile acid lithocholic acid was found after FO compared to CO-ingestion (99.6 vs. 109.4 mg/day; p=0.22). Since secondary bile acids are known promotors of colon carcinogenesis, these findings may implicate a favorable situation with respect to colon cancer prevention.
    Notes: Zusammenfassung Verschiedene Studien weisen auf einen protektiven Effekt von Fischöl bei der Kolonkarzinomentstehung hin. Mögliche Einflüsse auf die muscosale Prostaglandin-E2-Synthese wurden hierbei als Wirkungsmechanismus beschrieben. Zusätzliche Effekte auf die fäkale Exkretion von Gallensäuren könnten ebenso von Bedeutung sein, da insbesondere sekundäre Gallensäuren als Promotoren bei der Kolontumorentstehung angesehen werden. In der vorliegenden Studie wurde bei 12 gesunden Probanden der Effekt einer täglichen Supplementierung mit 11 g Fischöl (FO) bzw. Maiskeimöl (MO) über jeweils 4 Wochen zusätzlich zu einer fettreduzierten Basiskost (30 % der Gesamtenergie als Fett) auf die fäkale Exkretion von Gallensäuren untersucht. Die Analyse des fäkalen Gallensäurenspektrums erfolgte gaschromatographisch. Die Gesamtausscheidung an Gallensäuren war unter FO nicht signifikant verschieden von derjenigen unter MO (301,9 vs. 320,3 mg/Tag). Unter FO ergab sich jedoch eine tendenziell niedrigere Exkretion der sekundären Gallensäure Lithocholsäure als unter MO (99,6 vs. 109,4 mg/Tag, p=0,22). Da sekundäre Gallensäuren als ein wesentlicher Promotor der Kolonkarzinogenese angesehen werden, sind diese Veränderungen positiv im Hinblick auf eine mögliche Kolonkarzinomprävention zu werten.

    Description / Table of Contents: Zusammenfassung Chemische und physikalische Standardkennzahlen, wie zum Beispiel der Refraktions-und Farbindex, die Säurezahl und der K270-Wert, wurden mit den Gehalten an polaren Verbindungen sowie spezifischen thermooxidativen und hydrolytischen Fettbestandteilen verglichen, die in einem Sonnenblumenöl, das 75 mal zum Fritieren von Kartoffeln benutzt worden war, entstanden sind. Der Farbindex, die Säurezahl, der K270-Wert und der Gehalt an polaren Verbindungen stiegen signifikant (p〈0,05) nach 30 Fritierungen. Anschließend stabilisierten sich die drei letztgenannten Indices. Der Inhalt an polymeren Verbindungen und Triglyceridendimeren stieg signifikant nach 30 Fritierungen an (p〈0,05), während die oxidierten Triglyceride keine signifikante Steigerung aufwiesen. Der Gehalt an Diglyceriden und freien Fettsäuren, als Maß der hydrolytischen Vorgänge, zeigte während des Fritierprozesses keine signifikante Veränderung. Die signifikanten Korrelationen zwischen der Säurezahl und dem Gehalt an polaren Verbindungen, den dimeren und polymeren Triglyceriden und den oxydierten Triglyceriden, zwischen dem Farbindex und dem Gehalt an polaren Verbindungen und polymeren Triglyceriden, oder zwischen dem K270-Wert und den polymeren Triglyceriden zeigen, daß diese einfachen Standard-Methoden benutzt werden können und genauso nützlich sind wie mehr spezifische Methoden zur Bewertung von Fritierprozessen, wenn man die Ausgangswerte aller dieser Indices kennt.
    Notes: Summary Standard chemical and physical indexes, such as color index, acid value, and K270 were compared with the polar content and the specific thermoxidative and hydrolytic compounds originated during 75 potato fryings with sun-flower oil. The color index, acid value, K270 and total polar content showed a significant increase (p〈0.05) after the first 30 fryings, followed by a tendency of the last three indexes to reach a near-steady state. Triglyceride polymers and triglyceride dimers showed a significant increase (p〈0.05) after 30 fryings, while the oxidized triglycerides were not increased significantly after 30 fryings. The amount of diglycerides and free fatty acids related to hydrolytic alteration did not change significantly throughout the frying operations. The significant correlations between acid value and total polar content, triglyceride dimers, triglycerides polymers and oxidized triglycerides, or between color index and polar content and triglyceride polymers or between K270 and triglyceride polymers indicate that these simple and standard methods can be applied and they are as useful as more specific methods of evaluation in the monitoring of frying operations, provided that initial values of all of these indexes are available.

    Notes: Abstract In 1973, Richard Sylvan began his seminal essay, "Do We Need a New, an Environmental Ethic?" with these words: "It is increasingly said that ... Western civilization ... stands in need of a new ethic ... setting out people's relations to the natural environment." In the intervening years, it has increasingly been said that Western civilization is in need of ecocentrism, an ethic according to which a thing's value is derived from its contribution to the integrity, stability, and beauty of ecosystems. Do those interested in agricultural ethics need a new, an ecocentric, ethic? I argue that the answer is no. Agriculturalists must look elsewhere for an adequate ethic setting out our relations to the natural environment.

    Notes: Abstract The contrast between the nostalgic pictures on maple syrup packaging and sophisticated technologies actually used in the sugarbush and sugarhouse suggests disjunctures between image and practice in the contemporary North American maple syrup industry. This paper argues that although evidence of a “technological treadmill” exists within the maple syrup industry, as it does in other rural production sectors, such a trend is incomplete due to the increasing importance of consumption-based activities and concerns in the countryside. In response to the interests of tourists, second home owners and other increasingly influential non-producer groups, “traditional” maple enterprises persist, demonstrating a logic and appeal unaccounted for by treadmill theory. By addressing growing consumer concern about the appearance of the rural landscape, the health of the environment, and the quality of food, these “traditional” maple practices can provide distinct advantages for producers over technological modernization. The tension between technology use and tourism in the maple syrup industry offers insights about the role of small-scale specialty agriculture for sustainability in rural areas of advanced industrial countries undergoing social and economic change.

    Notes: Abstract Animal health is key to successful livestock production in developing countries. The development and delivery of vaccines against major epidemic diseases is one component of improving animal health. This paper presents a case study from Kenya on the production and delivery of a vaccine against Contagious Caprine Pleuropneumonia (CCPP), a major disease of goats. The vaccine, while technically a viable preventative measure against CCPP, has not been well integrated into Kenya's animal health care system. From February through November, 1992, the authors explored the organizational and policy constraints to vaccine production and distribution. Data were obtained through interviews, field visits, and available documents. Results suggest an animal health system that 1) does not have a well developed infrastructure to track, identify, and control animal diseases; 2) tends to place greater emphasis on cattle, rather than small ruminant health care; and 3) is not well linked in terms of research, development, and extension services.

    Notes: Abstract What are the more significant broad-based needs of animal health programs in developing countries? Essentially they are: health management programs, delivery systems, disease surveillance and monitoring of livestock movements, and improved technologies that are cost-effective and environmentally sound. Responsible program planning elicits important considerations that strengthen final results if integrated early into project design. Examples of these considerations include •the potential for intervention; •producers' requirements for animal health services; •present and future effect(s) of disease; •trends in livestock production and marketing; •affect of improved animal health technology on traditional production practices; •recurrent costs; and •affect of government policies on development and application of the technology. For what reasons do some project activities need to be redirected or continually sustained with donor support? A review of the case studies reveals that five major factors critically impact on project longevity. They are 1) initial expense and recurrent costs, 2) labor required, 3) long-term effectiveness, 4) difficulty in achieving objectives, and 5) government policies or civil strife. The U. S. Agency for International Development (USAID) has funded animal health projects for 30 years. Unlike most other bilateral projects, nearly one-third have continued for at least a decade. Given the nature of the biological cycle of livestock, animal health projects and programs require long-term commitments. USAID's investments in animal health projects continue to pay dividends despite continuously changing global political priorities and the redefining of development issues.

    Notes: Abstract Ethnoveterinary research, development, and extension (ERD&E) has emerged as a rich field for discovering, adapting, and transferring appropriate and sustainable animal health technologies to rural and peri-urban stockraisers, especially in Third World countries. This field is defined as the holistic, interdisciplinary study of local knowledge and practices, together with the social structure in which they are embedded, that pertain to the healthcare and healthful husbandry of animals used for a multitude of purposes. Especially in the Third World, livestock play a large number of important roles that are little understood or appreciated in today's First World. Study of these benefits and their role in Third World livelihoods offers numerous lessons that span not only the virtues but also some of the technical, ethical, and methodological challenges of working with local knowledge. ERD&E emerged as an internationally recognized branch of research in the mid-1970s largely in response to an increasing concern with animal health in the context of practical, field-level projects in animal agriculture. As many as 90% of the world's population continue to rely mainly on their own localized ethnomedicine for the bulk of their personal healthcare as well as their veterinary needs. With the escalating costs of Western healthcare technologies, it is essential to build upon this local knowledge. Of course, ethnoscience is not perfect, and recognition of the immense value of ERD&E does not imply that conventional science is to be abandoned. Rather each has much to learn from the other. Making knowledge by judiciously drawing upon insider and outsider, site-specific and universalistic, and both old and new understandings can take us back to a brighter development future.

    Notes: Abstract Tick and tick-borne diseases, especially East Coast fever, caused byTheileria parva, are amongst the most important factors limiting cattle production in Eastern, Central, and Southern Africa. In the past, they have been controlled mainly by the use of acaricides to kill ticks. Immunization has been shown to be an effective alternative method of control of tick-borne diseases in limited field trials. A development program has been initiated to produce vaccines and implement immunization on a wide scale in the region in a sustainable manner as part of an integrated tick and tickborne disease control program. The consequent reduction in cattle mortality is expected to have far-reaching benefits for the region.

    Notes: Abstract In 1942 California corporate agribusiness seized upon racist hysteria and pseudo "national security" issues to manipulate social ideology so that it could unlawfully seize tens of thousands of acres of productive farm land from law-abiding American citizens. It was such seizures that then allowed already existing large-scale capital to further consolidate California's agricultural resources while at the same time restructuring and increasing its concentration of the state's agricultural production and food manufacturing capabilities. Meanwhile, in "the most striking mass interference since slavery with the right of physical freedom," over 120,000 Japanese Americans were placed in concentration camps and illegally deprived of their property and human rights.

    Notes: Abstract Interest groups are advancing new statutory provisions to limit the liability of persons involved in equine activities. The first statute was adopted in Washington State five years ago, and subsequently twenty-nine other states have proceeded to adopt legislation regarding this issue. The new statutes, termed “Equine Liability Statutes,” provide immunity from liability for injuries and death arising from ordinary risks of equine activities. Drawing from policies involving the provision of assistance for needy interest groups and voluntary social prerequisites, two recommendations may be proffered. First, the good samaritan and recreational use models suggest that the statutes might require a donation to offset the loss of participants' rights before a person could qualify for the statutory dispensation. Second, an additional safety prerequisite regarding a helmet to encourage action to reduce head injuries may be appropriate to foster safer equine activities.

    Notes: Abstract A complex conjuncture of ideological constructions obscured and rationalized the systematic exploitation of farm women. First, farming and homemaking, to which people cling in an attempt to avert the alienation of wage labor, provide a basis for evaluating one's labor in terms that, ironically, makes them vulnerable to super-exploitation. Second, agrarian ideologies, with their strongly patriarchal bias, did not allow women to understand themselves as public actors. Modernizing elite ideologies, specifically the equation of entrepreneurial individualism and efficiency with “progress” and affluence, and the “cult of domesticity” with its redefinition of men's and women's roles, promised women greater equality within the family; however, these normative codes simultaneously opened the farm and home to greater dependence on capitalist markets. The ideology of entrepreneurial individualism also provided templates through which farm men and women (mis)understood their relative poverty as being the result of private, individual choices. In addition, virtually all media assumed a sector differentiated only by commodity, rendering size, class, or other distinctions invisible. Finally, the ideology of separate spheres, as it developed in the nineteenth century, created a segmented and discriminatory labor market for women. The period focused on, the late 1940s and the 1950s, was crucial in establishing the terms of the post-War order.

    Notes: Abstract The deteriorating living and working conditions suffered by California's farm workers and their families is associated with the escalating proportion of the agricultural labor market (ALM) provisioned by the state's farm labor contractors (FLCs). The increasing use of FLCs is the result of a restructuring strategy undertaken by Californian agribusiness to reduce the cost of labor, as well as responsibility for work place, labor, and immigration laws. The FLCs' rise to prominence as the bulwark between growers and workers within the state's ALM has been ensured by the internal dynamics of contractor firms. During almost three years of binational fieldwork in both California's San Joaquin Valley and rural Mexico I found that FLC management agents cultivate sociocultural practices and provide socioeconomic services that diffuse management-labor conflict within the agricultural sector. However, the existing literature concerning the FLCs focuses upon the firm, not its labor agents; therefore, FLC heterogeneity is emphasized, while ubiquitous management characteristics and practices are overlooked. As a result, recent legislation has had the unintended effect of augmenting the role played by management agents in “processing” an unending flow of new immigrant workers through the “revolving door” ALM, leading to the deterioration of conditions in rural California.

    Notes: Abstract African women farmers have an urgent need for adequate agricultural extension information. Training extension agents in gender related issues should have high priority, considering that the majority of farmers are women and have different roles, resources, constraints, and responsibilities from men. This paper examines the extent to which these issues are incorporated into the curriculum of the two Malawian institutions of agricultural education that train extensionists. It also considers the degree to which they are recruiting women officers into fields other than home economics. Administrators and lecturers at both institutions express a desire to integrate gender matters into the curriculum and to recruit more females into agricultural extension; yet both fall far short in meeting these goals. The conclusion provides recommendations on how African institutions of higher learning that train extension personnel might better accomplish these goals and suggests that African MOAs need to employ more women in agricultural research, extension, training, and policy-making positions.

    Notes: Abstract Organizing to promote sustainable rural development requires activists to connect social, economic, and environmental issues and to bring together disparate rural interest groups. This note describes a Swedish event — the 1994 Countryside Parliament (Landsbygds Riksdag) — that provides food for thought about how rural issues and organizations might be more effectively integrated in the northeastern USA. Rural movement building, Swedish style, entails a strong emphasis on cultural rituals, open dialogue, inclusiveness, and a spirit of compromise.

    Notes: Abstract In 1978, treatment and vaccination programs were recommended to control bovine trypanosomiasis and brucellosis in Ivory Coast. A single trypanocidal treatment of young calves dramatically reduced their mortality rate. A preliminary demonstration project was carried out in a limited area by the government agency SODEPRA, followed by demonstrations on nearly all the farms. The costs were covered by SODEPRA as one of their development projects. Over a period of time the farmers took charge of the treatments, both financially and physically. In 1992, the trypanocidal treatments were still widely used. The reasons for this success could be its dramatic efficacy, the simple technology employed, the low cost that was progressively charged to the farmers, and the fact that this was a long term extension project with continuous farmer training. The brucellosis control program started with an initial vaccination of 1 to 10 year old females followed by an annual vaccination of 1 to 2 year old heifers. One year later, a 37% reduction in the abortion rate was observed. The vaccination were paid for and carried out by SODEPRA. The control program then stopped but, because of growing problems with brucellosis, vaccinations started again in 1992. There is still a question of how vaccinations will be accepted when the farmers are required to share the cost for the control of a largely inconspicuous disease.

    Notes: Abstract Indigenous Zuni farming, including cultural values, ecological and biological diversity, and land distribution and tenure, appears to have been quite productive and sustainable for at least 2000 before United States influence began in the later half of the 18th century. United States Government Indian agriculture policy has been based on assimilation of Indians and taking of their resources, and continues in more subtle ways today. At Zuni this policy has resulted in the degradation and loss of natural resources for farming, reduction in the number of Zuni farmers and their control over farming resources, individualization of rights in farmland, consolidation of farm fields, and declining biological diversity in agriculture. The Zuni Sustainable Agriculture Project with the Zuni Irrigation Association and the Zuni community, are now working to revitalize sustainable Zuni farming, based on traditional values, knowledge, and technology, combined with modern knowledge and technology where appropriate. The United States government can support these efforts through appreciation of the need for Zuni control and the potential value of cultural and biological diversity.

    Notes: Abstract Mass media images offer audiences models for how to perform the social roles they depict. Opinions and other attributes of credible media models may likewise be embraced by audience members seeking to identify with those models. Thus farm magazine narratives about “successful” farmers may encourage readers to model or aspire to featured farmers' production and management techniques and ascribe legitimacy to models' responses to current agricultural issues. However, production of agrarian images in the mass media — including images of farms, farmers, and farmers' values — are inevitably biased such that media representations of successful farmers selectively present objective characteristics in terms of the media's own ideological frameworks, which in turn reflect the dominant ideology of the social relations in which the media are engaged. As a first step in identifying farm magazines' role in creating social models for farmers, this study analyzes articles featuring “successful,” “leading,” or “innovative” farmers in leading agricultural magazines. The featured farmers are categorized according to enterprise characteristics and characterizations of them and their management philosophies. Findings show that farmers in farm magazines have larger than average operations and are portrayed in a way that blends a “farming as business” orientation with more conventional agrarian values but that generally omits non-business aspects of farm life.

    Notes: Abstract The 1989 National Integrated Pest Management Program in Indonesia is a case of a breakthrough in national policy to enhance the ecological balance by conserving natural enemies and diminishing the indiscriminate use of pesticides in the protection of food crops. The Program provided training to agricultural officials and farmers to shift their perspectives in pesticide use through “knowledge transmission” rather than the transferal of “technological packages.” This paper examines how farmers, with the novel understanding they had, responded to the persisting top-down policy of the “complete credit packages” from the government rice intensification agencies and the recurrent outbreak of pests in 1990–1992. IPM knowledge and training provided initial understanding of, and the stimulus to discover, unknown phenomena on the basis of which farmers improved their knowledge and learning capacity. Constraints largely came from the inflexibility of the subsidized scheme of inputs and the inadequate explanation and extension services provided to farmers

    Notes: Abstract A grassroots protest against a large-scale confinement swine facility in Jackson Country, Michigan resulted in an out-of-court settlement that redressed the concerns of local residents. At the same time, the protest was instrumental in modifying state-level legislation to secure greater legal protection for intensive animal agriculture. The paper traces this ironic turn of events. Original efforts to regulate industrial agriculture were publicly reinterpreted by agribusiness as an assault on the "right to farm" of all farmers, regardless of scale and organizational management. Responding to this perception and informed by agricultural science, the state instituted voluntary "right to farm" guidelines. These guidelines based on state-of-the-art techniques and technologies now shield conforming operations from local complaints and "nuisance suits." By contrast, the rights of smaller farmers and rural residents are selectively disadvantaged.

    Notes: Abstract This essay critically examines the emerging view among some ethnologists that replicable models of sustainable management of tropical forests may be found within the knowledge systems of contemporary indigenous peoples. As idealized epistemological types, several characteristics distinguishing “indigenous” from “modern” knowledge systems are described. Two culturally distinctive land use systems in Latin America are compared, one developed by an indigenous group, the Huastec Maya, and the other characteristic of colonist farms in Rondonia, Brazil. While each of these systems reflects a different cultural-historical tradition, I argue that the process of knowledge formation and cultural adaptation is coevolutionary and continuous in both cases. The very concept of “indigenous” as a discrete analytic category is questioned; indigenicity alone cannot explain local adaptation of farming systems. Rather than dichotomize indigenous and colonist knowledge as inherently different categories, differences in land use patterns between such social groups may be more accurately viewed as reflecting different points on a single epistemological continuum.

    Notes: Abstract Can computer and information technology (IT), widely used in the development of livestock health and production, be of any benefit for Third World farmers and institutions? And if so, how can they be implemented on a large scale? The authors try to answer these and related questions based on experiences with computerized dairy herd health and production programs in Costa Rica. They conclude that IT is becoming a key instrument in the planning and operation of modern extension services and on-farm research for meeting the farmers' increasing needs for information and for enhancing their ability to manage the available resources efficiently. IT enables private sector extension services provided by farmer groups and advisors to give farmers access to information that they previously lacked. These services facilitate bottom-up planning. Where IT does not allow the farmer or extension agent to solve the problem, IT can be used to articulate the problem for researchers or policy makers to address. For low-resource smallholders, access to IT can be provided through local farmer organizations. At the institutional level, IT is giving a strong impulse to the improvement of on-farm research, teaching programs, institutional and disciplinary cooperation, regional networking, and to a better linkage with the productive sector.

    Notes: Abstract Employing the case of the global tuna-fish industry, it is argued that the process of globalization is contested terrain as it opens “free spaces” to some classes or groups and closes “free spaces” to others; that the nation-States' regulatory abilities are weakened; and finally, that while some social movements may gain, others are marginalized. Three basic conclusions are reached. (1) The industry's actions were successfully “contested” by environmental groups supported by the legislative and judicial branches of the US State. (2) Simultaneously, pro-environmental legislation is currently threatened, along with several national and international environmental accords. (3) Workers in the US and, particularly, in Latin America are paying the consequences of the introduction of pro-environmental legislation and the actions of transnational corporations (TNCs).

    Notes: Abstract The existence of sovereign rights over genetic resources is today well recognized in international law. However, the legal status of such resources in terms of property rights is still unclear. The consideration of this issue requires a clear distinction between physical and intangible property. Legislation in developed countries has extended patent protection to genetic resources, in addition to the protection of plant varieties via breeders' rights. The extension of protection and the implementation of the TRIPs Agreement may have important implications for breeding programs and trade in seeds. While intellectual property protection of genetic resources is rapidly advancing, considerable work is still to be done to ensure the compensation for the informal innovations made by local and indigenous communities.
