摘要

应用不同剂量的,60,Co, γ,射线照射含NT株弓形虫包囊的鼠脑匀浆后，以0.4%胰蛋白酶液消化，使弓形虫缓殖子从包囊中释放出来，并用生理盐水作连续10倍稀释，使成为含不同数量缓殖子的悬液，将此悬液接种小鼠，用生物检测方法确定其感染性。另设未经照射处理的缓殖子悬液感染小鼠的对照组。结果表明，,γ,射线0.55 kGy剂量为控制鼠脑中NT株弓形虫感染性的最小有效剂量。,γ,射线0.1 kGy剂量对弓形虫缓殖子感染性无明显影响，而0.45 kGy照射后，其感染性较前者下降了10,4,倍。

Abstract

Homogenates of mouse brains harbouring toxoplasma NT strain cysts were irradiated at various doses of ,60,Co ,γ, ray and digested with 0.4% trypsin buffer to release bradyzoites from cysts. The suspensions containing various number bradyzoites were obtained through a serial 10-fold dilution in saline solution and inoculated intraperitoneally into mice separately. Infectivity of toxoplasma bradyzoites was determined by bioassay of mice. A group of mice inoculated with non-irradiated bradyzoites was used as control. Results showed that the minimal effective dose of γ rays controlling infectivity of toxoplasma NT strain bradyzoites was 0.55 kGy. Effect of 0.1 kGy ,γ, rays on infectivity of toxoplasma bradyzoites was not significant. Infectivity of bradyzoites irradiated at 0.45 kGy had 10,4, fold reduction in comparison with that of 0.1 kGy.
