正常及感染曼氏血吸虫的小白鼠接种曼氏血吸虫尾蚴。接种部分皮肤在1/2、1、2、4、8、16、36、48及120小时后作活体检查。正常小白鼠,只有水肿及轻度粒细胞浸润,16小时,大部分童虫已透过真皮;感染的小白鼠在16～24小时,童虫成为强烈的混合细胞浸润的灶区,36～48小时,有明显的单核细胞浸润。用尾蚴盐水粗提液作皮内注射,两组动物产生的局部反应和尾蚴侵入所引起的相似。正常的小白鼠经输给正常或感染动物的
Normal and infected Schistosoma mansoni mice inoculated with Schistosoma mansoni cercariae. Inoculation of part of the skin after 1 / 2,1,2,4,8,16,36,48 and 120 hours for in vivo examination. Normal mouse, only edema and mild infiltration of granulocytes, 16 hours, most of the squirrels have penetrated the dermis; infected mice in 16 ~ 24 hours, the worm became a strong mixed cell infiltration of the area, 36 ~ 48 Hour, there is obvious infiltration of mononuclear cells. The cercariae brine crude extract for intradermal injection, two groups of animals produced by local reactions and cercariae invasion caused by the similar. Normal mice are lost to normal or infected animals
