本文报道的实验结果证实了用紫外线辐照的曼氏血吸虫尾蚴免疫的小鼠,能对同种尾蚴攻击感染产生部份抵抗力,并可以和丙种射线辐照尾蚴引起的抵抗力相比拟。作者以8至9周的雌性NMRI小鼠为实验动物,用浸尾法,将小鼠置于紫外线或丙种射线辐照过的尾蚴中暴露1小时,34天或31天后用正常尾蚴作攻击感染。于攻击感染后6周 The experimental results reported in this paper confirmed that mice immunized with UV-irradiated cercariae of Schistosoma mansoni could produce partial resistance to challenge with the same cercariae and could be comparable to those induced by c irradiation. The authors used 8 to 9-week-old female NMRI mice as experimental animals that were challenged with normal cercariae by exposure to cercariae exposed to UV or gamma irradiation for 1 hour, 34 days, or 31 days by the tipping method . 6 weeks after challenge infection
