    Notes: Pregnant mice were stimulated by heterologous erythrocyte and protein antigen, and the active immune responses of their offspring as measured by plaque-forming cells (PFC) were investigated. In offspring derived from mothers immunized by a suitable amount of T-dependent antigen, clear-cut suppression of development of specific PFC in spleen was observed over a significant period after delivery. The mechanism of this suppression was investigated, and the following results were obtained. When the heterologous erythrocyte was used as antigen, the more the specific PFC developed in the mother spleen, the stronger the suppression of PFC observed in their offspring. However, it is worthy of note that passive administration of antibody to pregnant mice did not induce suppression in their young. In case of the protein antigen ovalbumin (OVA), pregnant mice had to be injected with a suitable amount of antigen, along with aluminium hydroxide, for either primary or secondary stimulus to induce the suppression of specific PFC in their offspring. Soluble OVA administered to pregnant mice was not effective for inducing suppression in the offspring. Based on these results, some possible mechanisms are discussed concerning specific PFC suppression in the offspring when pregnant mice are stimulated.

    Life span elongation of Werner's syndrome fibroblasts by co-culture with origin-defective SV-40 DNA transformed cells (1984)

    Notes: Summary Co-culturing with origin-defective SV40 DNA-injected transformants, we succeeded in activating the limited growth potential of late-phase-II fibroblasts from patients with Werner's syndrome (WS cells). Residual life spans of three WS cell lines increased 2.3–5.6 fold. Co-culture with normal IMR-90 cells showed variable effects on different WS cell lines.

    Description / Table of Contents: Abstract Алкилирование боквой цепочки толуола, приводящее к образованию этилбензола или стирола, быо исследовано, используя обычный проточный реактор при температурах около 475°C. Катализатор, активированный Cs2O (10–20 вес. %) и приготовленный методом импрегнирования, обладает превосходной активностью и селективностью. Температура кальцинирования катализатора и добавка CO2 или H2O в реагирующую смесь оказывают влияние на активность катализатора удивительным образом.
    Notes: Abstract The side-chain alkylation of toluene to form ethylbenzene or styrene has been investigated using a conventional flow reactor at temperatures near 475°C. Cs2O (10–20 wt. %)-activated carbon catalyst prepared by an impregnation method showed an excellent activity and selectivity. The calcination temperature of the catalyst and the addition of CO2 or H2O into the reactant mixture affected the catalyst activity in a striking manner.
