    Notes: The fabrication of n+ and p+ silicon thin film by using a combination of "spin-on-glass'' and XeCl excimer-laser doping is described. The doping can be achieved by rapid dopant atom diffusion into molten silicon from a spin-coated film containing the dopant. This technology offers the advantages of process simplicity, low processing temperature, and ultrashallow high-concentration doping. The obtained sheet resistances (2 kΩ/(D'Alembertian) for n+ and 9 kΩ/(D'Alembertian) for p+) are acceptable for thin-film transistors (TFTs). The energy required for doping into a thin film was less than half of that for a silicon wafer. This is mainly due to the absorption rate difference between noncrystalline and crystalline silicon. This process appears extremely promising for TFT fabrication.

    Notes: Stability against the interchange mode in heliotron devices is investigated, taking into account the effects of the resistivity, current diffusivity, ion viscosity, and thermal diffusivity. Critical beta for the low-mode-number stability is found at the finite beta value. For the range of plasma parameters of the present experiments, the resistive mode and current diffusive mode set comparable critical beta values, which are consistent with experimental observations. In future high-temperature plasmas, the current-diffusive mode could be important in determining the stability limit for the global mode.

    Notes: An analytic formula is derived for the loss cone in toroidal helical systems. Particular emphasis is put on the loss region for the particles that are barely trapped in the helical ripples. Effects of the radial electric field and shifts of the magnetic axis are discussed. Comparison with the numerical calculation confirms that the simple analytic formula gives good approximations.

    Notes: Abstract The radiographic and computed tomographic findings of a gastric duplication cyst contiguous to the stomach first diagnose in a 13 year-old-woman are presented. She revealed pyloric stenosis and chronic relapsing pancreatitis. In the smooth muscle wall and the connective tissue of the cyst lay aberrant pancreatic tissue and large neural bands.

    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: Abstract Twenty patients with hepatitis B e antigen (HBeAg) -positive chronic hepatitis, who received 40 mg of prednisolone per day for three weeks followed by withdrawal, were studied for changes in alanine aminotransferase (ALT), triiodothyronine (T3), thyroxine (T4), and hepatitis B virus DNA polymerase (HBV-DNAp) levels determined before and during prednisolone treatment and after its withdrawal. A decreased HBV-DNAp level of less than 100 cpm/ml three to five weeks after withdrawal was considered a sign of efficacy and was shown in 10 patients (50%). Significant differences were found between ALT levels, between T3 levels, and between the T3/T4 ratios assayed in the third and fourth weeks in total (P〈0.02) and in the group in which efficacy was demonstrated (P〈0.01). The T3/T4 ratio in the third week in the effectively treated group was significantly less than that in the noneffectively treated group (P〈0.05). Prednisolone withdrawal effective for HBV-DNAp was shown in the patients with a decreased T3 level and the T3/T4 ratio at the third week and an increase in the ALT level after the withdrawal. The ALT level increased after the T3 level decreased. Changes in the T3 level or the T3/T4 ratio represent a marker for effectiveness of prednisolone withdrawal and for determination of combination therapy after steroid withdrawal.
