作者观察了曼氏血吸虫尾蚴直接注射到小白鼠腹腔转变成童虫的速率及程度,同时研究了尾蚴装在Millipore弥散袋中移植到腹腔内转变童虫的情况。尾蚴注入腹腔后3小时,约15%的接种物可以从腹腔洗液中找到。但全部小生物已经明确地变成童虫。其表现为:(1)尾巴已失落;(2)在生理盐水中或血清中能生活,但不能在清水中生活;(3)尾蚴的精确形状没有了;(4)没有形成尾蚴膜的作用。将尾蚴装在弥散袋中移植到腹腔内2小时后全部都转变
The authors observed the rate and extent of cercariae of Schistosoma mansoni injected directly into the peritoneal cavity of mice, and studied the cercariae transplanted into the peritoneal cavity to transform the squirrels in a Millipore dispersion bag. Three hours after injection of cercariae into the abdominal cavity, approximately 15% of the inoculum can be found from the abdominal cavity washings. But all small creatures have definitely become squirrels. Its performance is: (1) tail has been lost; (2) can live in saline or serum, but can not live in water; (3) the precise shape of cercariae is not; (4) the role of the formation of cercariae membrane . The cercariae in a diffusion bag installed in the abdominal cavity after 2 hours all changed
