E-64, L-trans-epoxysuccinyl-leucylamido (4-guanidino) butane, a specific inhibitor of thiol proteases originally isolated from a culture broth of fungi, and its synthetic analogues, were examined for immune responses to the splenocytes of BDF1 mice. In the cultures of 2-day-primed splenocytes of the mice, E-64 and its close analogues, increased the number of direct splenic hemolytic plaque forming cells (PFC). In addition, it was demonstrated that E-64 enhanced the PFC responses in the mice. These results suggested that some thiol proteases might be involved in the immune response process in mice. 相似文献

Detailed cross-sectional temperature and oxygen distributions during winter were examined over 5 years (2003–2007) in large,
warm, monomictic Lake Biwa. The distribution patterns showed year-to-year variation in the degree of spatial heterogeneity
and indicated that both convective mixing and gravity currents contributed to the delivery of oxygen to the profundal zone.
We encountered a warm winter in 2007, when deep-water oxygenation was delayed by more than a month relative to normal years.
Data obtained during the period of oxygenation in 2007 suggest that the timing of complete oxygenation of the bottom water
(or lower layers of the hypolimnion) was controlled by physical processes responsible for destruction of the weak thermal
stratification near the bottom. This study revealed that Lake Biwa is sensitive to year-to-year variations in winter meteorological
conditions. Specifically, the bottom environments are highly susceptible to a warm winter, especially when it follows a cold
winter. 相似文献
