    Beschreibung: Rats and guinea pigs, when immunized with mouse nerve growth factor, produce antibodies that cross-react with their own nerve growth factor. The antibodies reach developing offspring of these animals both prenatally (rats and guinea pigs) and postnatally (rats). Depriving the fetus of nerve growth factor in this way results in the destruction of up to 85 percent of dorsal root ganglion neurons as well as destruction of sympathetic neurons. Sensory neurons of placodal origin in the nodose ganglion were not affected. These data demonstrate that dorsal root ganglion neurons go through a phase of nerve growth factor dependence in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnson, E M Jr -- Gorin, P D -- Brandeis, L D -- Pearson, J -- HD12260/HD/NICHD NIH HHS/ -- HL20604/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1980 Nov 21;210(4472):916-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7192014" target="_blank"〉PubMed〈/a〉

    Beschreibung: When pregnant rats were fed a 50 percent galactose diet there was a striking reduction in oocyte number in the offspring. The most prominent effects were noted after exposure to galactose during the premeiotic stages of oogenesis. Prenatal exposure to galactose or its metabolites may contribute to the premature ovarian failure characteristic of human galactosemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Y T -- Mattison, D R -- Feigenbaum, L -- Fukui, H -- Schulman, J D -- New York, N.Y. -- Science. 1981 Dec 4;214(4525):1145-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7302587" target="_blank"〉PubMed〈/a〉

    Beschreibung: Female prairie voles (Microtus ochrogaster) exposed to a single drop of male urine on the upper lip showed changes in concentrations of luteinizing hormone-releasing hormone (LHRH) and norepinephrine in olfactory bulb tissue; no such changes occurred in dopamine concentration. The changes were measured in the posterior but not the anterior olfactory bulb tissue of females within 1 hour after they were exposed to urine. These females also showed rapid increases in serum concentrations of luteinizing hormone. Females exposed to water on the upper lip showed none of these changes. These results suggest that in this species LHRH and norepinephrine in the olfactory bulb may mediate luteinizing hormone release in response to external (pheromonal) chemical cues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dluzen, D E -- Ramirez, V D -- Carter, C S -- Getz, L L -- HDO9328/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1981 May 1;212(4494):573-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7010608" target="_blank"〉PubMed〈/a〉

    Beschreibung: Urine of the human fetus stimulated prostaglandin biosynthesis in vitro by increasing the conversion of arachidonic acid into prostaglandins. The stimulatory activity in urine from fetuses delivered at term after labor of spontaneous onset was greater than that in urine from fetuses delivered by cesarean section at term before the onset of labor. Such stimulation of prostaglandin biosynthesis by the fetal membranes, by way of a substance released into the urine and thence into amniotic fluid, could serve as a signal for the initiation of parturition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Strickland, D M -- Saeed, S A -- Casey, M L -- Mitchell, M D -- 5-P50-HD11149/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):521-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6573023" target="_blank"〉PubMed〈/a〉

    Beschreibung / Inhaltsverzeichnis: Résumé Les fémora de rats jeunes et âgés sont comparés à l'aide de tests mécaniques en estimant leur capacité de résister à des stress physiologiques de grossesse et de lactation. Dans les deux groupes, on note une tendance de résistance plus élevée de l'os à la fin de la grossesse par rapport à des animaux vierges de même âge. Cet effet est plus net chez des animaux plus âgés. D'où les os des animaux plus âgés sont presque aussi résistals, à la fini de la lactation, que ceux d'animaux vierges du même âge, bien que les os soient résistants pendant la lactation. Les os d'animaux jeunes en lactation sont moins résistants que ceux d'animaux vierges du même âga. L'augmentation de la force d'animaux, après délivrance, est en rapport avec le poids plus élevé de ces animaux par rapport à des animaux vierges: la surface transversale des os d'animaux âgés, après délivrance, et le poids qu'ils supportent, sont en rapport direct avec le poids de l'animal à sa mort.
    Kurzfassung: Zusammenfassung Die Femora von jüngeren und älteren Ratten wurden mittels mechanischer Tests miteinander in Bezug auf ihre Fähigkeit verglichen, der physiologischen Beanspruchung von Schwangerschaft und Lactation standzuhalten. In beiden Altersgruppen zeigte sich eine Tendenz der Knochen, am Ende der Schwangerschaft stärker zu sein als diejenigen von ungedeckten Tieren desselben Alters. Diese Wirkung war ausgeprägter in den älteren Tieren. Als Folge waren die Knochen der älteren Tiere am Ende der Lactation beinahe so stark wie diejenigen der ungedeckten Tiere deselben Alters, obwohl die Knochen während der Lactation schwächer wurden. Bei den jüngeren Tieren waren die Knochen am Ende der Lactation schwächer als diejenigen der ungedeckten Tiere. Möglicherweise hat die Zunahme der Knochenstärke nach der Schwangerschaft einen Zusammenhang mit dem höheren Gewicht dieser Tiere im Vergleich mit den ungedeckten Tieren; die Querschnittfläche der Knochen älterer postpartaler Tiere und die Last, die sie aushielten, hatten einen engen Zusammenhang mit dem Gewicht des Tieres bei dessen Tod.
    Notizen: Abstract The femora of younger and older rats were compared, by means of mechanical tests, for their ability to withstand the physiological stresses of pregnancy and lactation. In both age groups there was a tendency for the bones at the end of pregnancy to be stronger than those of virgins of the same age. This effect was much more clearly marked in the older than in the younger animals. As a result, the bones of older animals were almost as strong, at the end of lactation, as those of virgins of the same, age, even though the bones became weaker during lactation. The bones of younger lactators were weaker than those of virgins of the same age. It is possible that the increase in strength of the postpartum animals is related to the greater weight of such animals compared with virgins; the cross-sectional area of the bones of the older postpartums, and the load they bore, had a high correlation with the weight of the animal at death.

    Notizen: Summary The clear morphological differences between the granulated metrial gland (GMG) cells which develop in the uteri of rats and mice have been used to assess the origin of GMG cells in radiation chimaeras. Lethally irradiated mice were reconstituted with either rat or mouse bone marrow cells. Control mice were ovariectomised. A schedule of steroid injections was carried out allowing deciduoma formation to be induced in the irradiated and control animals. Deciduoma formation was impaired, and there were few GMG cells in the irradiated, bone marrow-reconstituted mice in comparison with the ovariectomised controls. However, it was possible to identify, by their distinctive morphology, 1) rat GMG cells in the mice reconstituted with rat bone marrow cells, and 2) mouse GMG cells in the mice reconstituted with mouse bone marrow cells. Conversely, no typical mouse or rat GMG cells were identified in mice reconstituted, respectively, with rat or mouse bone marrow cells. The observations indicate that GMG cells differentiate from a precursor derived from bone marrow.

    Beschreibung: Newborn infants, chronically exposed in utero to low doses of methadone with or without concomitant heroin, display more rapid eye movement sleep and less quiet sleep than control infants, while babies fetally exposed to both opiates and nonopiates have less organization of sleep states. Other perinatal factors, such as birth weight and gestational age, are related more to the amount of fetal drug exposure than to the type.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dinges, D F -- Davis, M M -- Glass, P -- New York, N.Y. -- Science. 1980 Aug 1;209(4456):619-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7190326" target="_blank"〉PubMed〈/a〉

    Beschreibung: A striking inverse correlation was found in umbilical cord plasma between the concentrations of dehydroisoandrosterone sulfate and low-density lipoprotein (LDL)-cholesterol but not high-density lipoprotein-cholesterol or very low density lipoprotein-cholesterol. Dehydroisoandrosterone sulfate is a major secretory product of the human fetal adrenal and the principal precursor of placental estrogen production. The data suggest that the concentrations for LDL-cholesterol in fetal plasma are influenced by the rate of utilization of LDL-cholesterol by the fetal adrenal for steroidogenesis and are not necessarily related to a genetic predisposition for hypercholesterolemia or other lipoprotein disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parker, C R Jr -- Simpson, E R -- Bilheimer, D W -- Leveno, K -- Carr, B R -- MacDonald, P C -- New York, N.Y. -- Science. 1980 May 2;208(4443):512-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6445079" target="_blank"〉PubMed〈/a〉
