摘要:   目的:探讨日本血吸虫26kDa基因重组蛋白(rSjc26GST)抗日本血吸虫生殖作用及其免疫机制。方法:小鼠经rSjc26GST免疫,攻击感染日本血吸虫尾蚴40±1条,于6wk后解剖检虫体,计算虫数与肝组织和脾组织内的虫卵数,并对虫体主要生殖器官作透射电镜超微结构的观察。结果:证明rSjc26GST具有明确的抗生殖免疫作用。与对照组相比,免疫鼠减虫率为30.0%,肝组织和脾组织内虫卵减少率分别为57.1%与79.9%,透射电镜观察显示免疫鼠体内雌虫的卵黄腺及雄虫的睾丸组织均产生不同程度的抑制作用,主要表现为卵黄细胞胞质中卵黄球、卵黄滴、脂滴和睾丸组织中精细胞、支持细胞胞质中的脂滴数量均有明显减少。结论:rSjc26GST有抗日本血吸虫生殖的作用,使虫体生殖器官受到损害

Abstract:  AIM: To observe the anti fecundity effect of recombinant Sjc26 GST against Schistosoma japonicum and its mechanism.METHODS:Male ICR mice were immunized with rSjc26 GST.Five days after final injection, mice of the immunization and control groups were challenged with 40±1 S.japonicum cercariae . All mice were sacrificed at 6 weeks after challenge.RESULTS: The worm reduction rate was 30 0%,and the egg reduction rates in the liver and in the spleen were 57 1% and 79 9%, respectively. Inhibition of the vitelline gland and testis was also observed by transmission electron microscopy. The number of vitelline globes, vitelline droplets and lipid droplets in the cytoplasm of vitelline cell and the number of lipid droplets in the supporting cells and the number of spermatids in the testis were apparently reduced.CONCLUSION:The damage of the main reproductive organs of Schistosoma japonicum was one of the factors responsible for rSjc26 GST bound anti fecundity action.
