We studied the interruption performance of CF<sub>3</sub>I gas because its environmental effect is smaller than that of SF<sub>6</sub> gas with a model arc-extinguishing chamber. First, we measured the arc time constant and arc power loss coefficient using Mayr's equation. Comparing CF<sub>3</sub>I with other gases, the arc time constants are(More)
It is known that 17beta-estradiol (E2-beta) increases the production of nitric oxide. We have demonstrated that E2-beta prevents renal injury and suppresses renal endothelin-1 overproduction in ischemic acute renal failure in rats. In the present study, we investigated whether N(G)-nitro-L-arginine methyl ester, a nitric oxide synthase inhibitor, can(More)
Tetraspanin membrane protein, epithelial membrane protein 3 (Emp3), is expressed in lymphoid tissues. Herein, we have examined the Emp3 in antigen presenting cell (APC) function in the CD8+ cytotoxic T lymphocytes (CTLs) induction. Emp3-overexpressing RAW264.7 macrophage cell line derived from BALB/c mice reduced anti-C57BL/6 alloreactive CTL induction,(More)
We examined the potential for biological control of black rot of broccoli, caused by Xanthomonas campestris pv. campestris (Xcc), using nonpathogenic Xanthomonas sp. strain 11-100-01 (npX) mixed with bacteriophage XcpSFC211 (pXS). Inoculation of intact broccoli plants in greenhouse trials with either npX or pXS did not control black rot. After injured plant(More)
