摘要: 为改进日本血吸虫无菌活虫卵的制备方法, 将感染血吸虫尾蚴38~45 d的家兔剖杀, 于无菌条件下摘取肝脏, 匀浆, 以360目分样筛过筛, 截留成熟及未成熟虫卵, 用1.2%生理盐水反复洗涤数次后收集虫卵, 置0.25%胰蛋白酶消化液中消化2 h, 当混杂组织被消化成单个细胞后, 再用360目分样筛过滤去除杂质细胞, 用含100 μl/ml氨苄青霉素与硫酸链霉素双抗的Earle’s平衡盐溶液反复洗涤数次, 获得大量纯净、 活性高达(95.1±6.4)%的无菌虫卵。本法收集虫卵工作效率较高。

Abstract: To prepare a large amount of pure alive Schistosoma japonicum eggs, rabbit was infected with 2000 cercariae and its liver was taken aseptically 38-45 days after infection and homogenized. The homogenate was screened through different sieves(60, 120, 200, 300, 360 meshes per inch respectively), and washed with 1.2% NaCl. The eggs and leftover were then digested with 0.25% trypsin for 2 hours, sieved over 360 meshes per inch and washed with RPMI 1640 medium. The collected eggs reached to (95.1±6.4)% of live eggs, with a high efficiency.
