    Abstract Prostaglandin E2 (PGE2) at concentrations more than 1×10−8 M markedly suppressed the cell proliferation and release of soluble molecules of interleukin-2 receptor (sIL-2R), CD4 (sCD4) and CD8 (sCD8) from phytohemagglutinin (PHA)-stimulated normal human mononuclear cells (MNC) in a dose-related manner. To further elucidate the subcellular mechanism of the inhibitory effect of PGE2 on PHA-stimulated MNC, intracellular concentration of glutathione (GSH) in PHA-stimulated MNC was sequentially measured from day 1 to day 3 by enzymic method. Furthermore, the effect of PGE2 on nuclear DNA including DNA strand breaks in alkali treatment and DNA fragmentation (apoptosis) of PHA-stimulated MNC were also measured. We found intracellular GSH levels were significantly decreased in the early stage of lymphocyte activation (day 1), but no evidence of increased DNA stand breaks or apoptotic process appeared in 3-day culture. In addition, butathione sulfoximine (a specific GSH inhibitor) and dibutyryl cyclic AMP also exhibited both proliferation inhibition and GSH-decreasing effect on PHA-stimulated MNC as well as PGE2. These results suggest that the immunosupressive effect of PGE2 is mediated by the decreased generation of intracellular GSH, but not by the increased DNA strand breaks or apoptotic mechanism in the cells.

    Description / Table of Contents:
    Abstract Добавление малых количеств меди к никелю Ренея увеличивает его активность в гидрогенизации кротонового альдегида и его селективность в гидрогенизации связи C=O. Повышенные количества приводят к повышенной селективности, но к пониженной активности. Для обьяснения этого был использован подход химической координации на катализаторе.
    Notes:
    Abstract Addition of small amounts of copper to Raney Ni increases its activity for hydrogenation of crotonaldehyde and its selectivity for C=O bond hydrogenation. Higher amounts lead to higher selectivity but lower activity. The coordination chemical approach to catalysis was used to explain this result.

    Description / Table of Contents:
    Abstract Распределение компонентов в катализаторе HG-1, промотированном окисями редкоземельных металлов (успешно разработанный авторами) и используемом в синтезе аммония, определяли на основе электронной микропробной фотографии. Объяснено влияние примесей на активность, а также исключительно большое время жизни катализатора.
    Notes:
    Abstract The distribution of components in the HG-1 ammonia catalyst promoted by rare earth oxide (successfully developed by the authors) was analyzed by electron microprobe photography. The results enable us to explain the effect of additives upon the activity as well as the remarkably high lifetime of catalyst.
