免疫接种适量的照射致弱尾蚴能使小鼠得到保护而抵抗曼氏血吸虫病。较普遍的看法是细胞免疫机制而并非体液免疫机制在鼠抗感染中起主要作用。作者的试验结果如下:1.抵抗力产生的时间:免疫接种组(v)小鼠免疫接种500条200Gy γ-射线照射致弱的尾蚴经皮接种和对照组(c)小鼠在不同间隔时间均以200条尾蚴攻击感染,5周后,以成虫检获率按公式计算抵抗力程度。免疫接种10天后攻击感
Immunization with the right amount of irradiated cercariae can protect mice against schistosomiasis. The more common view is cellular immunity rather than the humoral immune mechanisms that play a major role in mouse anti-infectives. The author’s test results are as follows: 1. Resistance time: Immunization group (v) Mice immunized 500 mice with weak cercariae irradiated by γ-ray of 200Gy percutaneous inoculation and control group (c) mice at different time intervals After 200 cercariae were challenged with the infection, after 5 weeks, the detection rate of adult worms was calculated according to the formula. 10 days after immunization attack sense
