    Notes: UV light irradiation effects on prebaking and silicon epitaxial growth is studied. An ArF excimer laser, a KrF excimer laser, and a Hg-Xe lamp are used as light sources. The epitaxial growth is carried out using a SiH2Cl2/H2 system under reduced pressure. ArF radiation and Hg-Xe radiation are found to be effective for volatilizing native SiO2 on silicon-substrate surfaces even at low temperatures. When a substrate surface is irradiated with these UV radiations during prebaking and epitaxial growth, epilayer surface morphology and crystalline quality are much improved. Furthermore, the epitaxial growth rate seems to be enhanced photothermally by excimer laser radiations, and photochemically by Hg-Xe radiation.

    Notes: Magnetite colloidal fluid with a carrier fluid of deuterium oxide (D2O) was prepared to eliminate the incoherent scattering by hydrogen nucleons and the depolarization of cold neutrons was measured. The magnetic fluid was cooled down to 17 K in an external magnetic field of 10 kOe. The sample exhibited a finite residual magnetization Mr, which decreases with increasing temperature from 17 K. With elevating the temperature from 17 to 300 K, the depolarization was measured in three cases in which the directions of the beam, Mr, and polarization are mutually changed. The polarized neutrons transmitting through the sample were depolarized by the magnetic moments in the colloidal particles. The polarizations as a function of the product of Mr and neutron wavelength λ at different temperatures reduce to the same functional form. The model which shows that no interactions exist among the ferrous colloidal particles succeeds partly in explaining the experimental results.

    Notes: Using a new process, a large grain polycrystalline silicon layer was grown directly from molten Si on a single-crystal silicon wafer at a rate 100 times faster than the conventional chemical vapor deposition process. A polycrystalline silicon layer was also produced on a single-crystal silicon wafer, which had an oxide layer and etched V grooves, through use of an additional ultrasonic wave effect in this process. A layer thickness of 100–600 μm and a grain size of 10 μm–3 mm were controllably obtained. After the growth of the polycrystalline layer, dislocation densities of 4×105 cm−2 for the single-crystal silicon substrate, and 2×106 cm−2 for the polycrystalline layer were obtained. Some devices were fabricated from the products of this new process, and the characteristics of these devices were investigated.

    Description / Table of Contents: Zusammenfassung Der Glukosetoleranztest wurde bei 10 Ainu und 20 Japanern (Studenten) durchgeführt. Signifikante Unterschiede im Blutzucker, immunreaktiven Insulin und humanen Wachstumshormon im Plasma wurden nach der Glukosegabe nicht gefunden. Die Nüchternwerte der freien Fettsäuren waren in den Ainu signifikant tiefer als bei den Japanern. Die Aenderungen der freien Fettsäuren nach Glukose waren bei den Ainu geringer, während die Japaner einen ausgeprägten "rebound effect" aufwiesen.
    Abstract: Resume On a appliqué un test de tolérance à la glucose à 10 Aïnous et à 20 Japonais d'autres races (tous étudiants). On n'a pas décelé de différence significative après administration de glucose ni dans la teneur en sucre du sang, ni dans le taux d'insuline immunoréactive, ni dans les hormones humaines de croissance contenues dans le plasma. Les coefficients d'acides gras libres (FFA), après un jeûne ont été plus bas chez les Aïnous que chez les Japonais et cela de façon significative. La modification des acides gras libres après administration de glucose a été moins marquée chez les Aïnous alors que les Japonais présentaient un net "effet de rebondissement".
    Notes: Abstract In an attempt to find out specific characteristics in carbohydrate metabolism in the Ainu, if any, glucose tolerance test was carried out. Between the Ainu and non-Ainu Japanese no differences were observed in the blood glucose, immunoreactive insulin and human growth hormone levels in the plasma after glucose load. Fasting levels of plasma FFA were significantly lower in the Ainu than in the Japanese. Changes in the FFA after glucose load were less in the Ainu, while the Japanese showed a marked rebound of the plasma FFA.

    Description / Table of Contents: Zusammenfassung Das Verhältnis von Oelsäure in der freien Fettsäurenfraktion (FFA) im Plasma war bei Japanern (n=9) höher als bei Ainus (n=5). Nach Glukose war das Oelsäure-Verhältnis vermindert, während in beiden Gruppen Stearinsäure anstieg. Bei den Japanern ergaben sich ausserdem ein Abfall der Linolensäure und Austiege der Palmitin- und Myristinsäure. Wenn der Plasma FFA-Spiegel nach Noradrenalin-Injektion anstieg, stieg der Oelsäureanteil und fielen die Palmitin-, Myristin- und Laurinsäureanteile und die Zusammensetzung war wie die von Depotfett. Es wird angenommen, dass die Unterschiede in der Zusammensetzung der Plasma FFA bei Japanern und Ainus Folge der unterschiedlichen FFA-Spiegel waren, die bei den Ainu signifikant tiefer lagen.
    Abstract: Resume La proportion d'acide oleique dans l'ensemble des acides gras libres (FFA) du plasma sanguin est plus marquée chez les Japonais (n=9) que chez les Aïnous (n=5). La proportion d'acide oleique a diminuê après l'administration de glucose, car, dans les deux groupes, la teneur en acide stéarique s'est renforcée. On constante en outre une diminution de l'acide linoleique et une augmentation des acides palmitique et myristique. Lorsque, après injection de noradrénaline, le taux de FFA du plasma se relève, on constate une augmentation des quantités relatives de l'acide oleique au détriment de la part prise par les acides palmitique, myristique et laurique et leur composition est semblable aux dépots adipeux. On peut ainsi admettre que les différences de composition du FFA plasmatique découlent du taux dissemblable du FFA entre Aïnous et Japonais. Ce taux est significativement inférieur chez les premiers.
    Notes: Abstract The ratio of oleic acid in the plasma FFA fraction was higher in the Japanese than in the Ainu. When glucose was administered, the proportion of oleic acid was reduced, while that of stearic acid increased in both groups. In the Japanese, moreover, a decrease in linoleic acid and increases in palmitic and myristic acids were also observed. As the plasma FFA level rose after injection of norepinephrine, the proportion of oleic acid increased and that of palmitic, stearic, myristic and lauric acids decreased, and the composition approached the pattern of depot fat. It was inferred that the difference observed in the plasma FFA composition between the Ainu and Japanese was attributable to the difference in the plasma levels of FFA which was significantly lower in the Ainu.

    Description / Table of Contents: Zusammenfassung Die Verteilung der Fettsäuren im subcutanen Fett des Menschen wurde gaschromatographisch bestimmt. Die Fettproben wurden in einer Klinik im Norden Japans bei Operationen entnommen. Der prozentuale Anteil an gesättigten Fettsäuren war höher im Fett der Brust und Bauchwand und der an einfach ungesättigten Fettsäuren im Fett des Vorderarms und Beines. Die Anreicherung ungesättigter Fettsäuren in den Extremitäten war im Winter ausgeprägter als im Sommer. In der Zusammensetzung der Fett des Rumpfes fehlte eine jahreszeitenabhängige Variation.
    Abstract: Resume Par analyse chromatographique des gaz, on a déterminé la répartition des acides gras dans les tissus adipeux sous-cutanés de l'homme. Les échantillons de graisse ont été prélevés lors d'opérations dans une clinique du nord du Japon. La proportion d'acides gras saturés était plus élevée dans la graisse de la poitrine et du ventre, alors que les acides gras mono-nonsatures l'emportaient dans l'avant-bras et dans les jambes. L'accumulation d'acides gras non saturés dans les extrémités était plus accentuée en hiver qu'en été. On n'a par contre pas pu établir de relation saisonnière dans la composition de la graisse du tronc.
    Notes: Abstract The fatty acid composition of human subcutaneous fat obtained at a hospital in the north of Japan, was determined by means of gas chromatography. In the fat of chest and abdominal walls percentages of saturated fatty acids were higher and those of mono-unsaturated ones were less in comparison with respective values in the fat of forearm and leg. The unsaturation of the fat of extremities was more pronounced in the winter than in the summer, while no seasonal variations were observed in the fatty acid composition of the fat of trunk.

    Notes: Summary In vagotomized rats, 2 weeks after surgery, the amplitude of the circadian rhythm of plasma corticosterone was extremely low, indicating that gastrointestinal activity may be in part involved in the hypothalamo-hypophyseal circadian rhythmicity.

    Description / Table of Contents: Zusammenfassung Eine geringe Dosis Noradrenalin, die bei nicht-Ainu Japanern unwirksam war, bewirkte bei Ainus eine ausgeprägte Erhöhung des Stoffwechsels, des Plasmaspiegels, der freien Fettsäuren und der Gesamt-Ketonkörper. Die Noradrenalin-Empfindlichkeit der Ainus wird als Kennzeichen besonderer Kälteanpassungsfähigkeit erklärt, das für diesen Volksstamm kennzeichend ist.
    Abstract: Resume Une faible dose de noradrénaline, dose qui reste sans effet sur les Japonais n'appartenant pas à la race des Ainous, provoque au contraire une nette élévation du métabolisme énergétique chez les natifs de cette race. Cette élévation se signale notamment par le relèvement du taux des acides gras libres et des masses de kétone dans le sérum sanguin. L'extrême sensibilité des Ainous à la noradrénaline explique la facilité avec laquelle les gens de cette race s'adaptent au froid. Cette facilité d'adaptation est d'ailleurs une des caractéristiques de cette race.
    Notes: Abstract A small dose of noradrenaline, which was ineffective in non-Ainu Japanese subjects, caused marked elevations in energy metabolism and plasma levels of FFA and total ketone bodies in the Ainu. The striking sensitivity to noradrenaline of the Ainu is assumed to indicate a characteristic feature of cold adaptability of this ethnic group.
