摘　　要：目的 :了解钉螺组织经茶树籽处理的影响。方法 :应用电镜技术观察处理后的钉螺肝脏及生殖腺组织的超微结构。结果 :钉螺在茶树籽作用 2 4 h后 ,肝内细胞受损。雄性生殖细胞有凝固性及溶解性变化 ;成熟精子细胞膜肿胀与内部结构分离 ,线粒体鞘呈现凝集型 ,支持细胞可见凝固性改变 ,且彼此断裂并与生殖细胞分离。雌性钉螺生殖腺可见卵细胞肿胀 ,严重时滤泡细胞有破裂 ,卵细胞膜则可丧失完整性。结论 :茶树籽能损伤钉螺的生殖腺和肝脏。AIM:To observe the lesions of Oncomelania hupensis after treatment with the seed of camellia sinensis(SCS) .METHODS:The tissue of the hepatopancreas and genital system in normal and SCS- treated Oncomelania hupensis were observed by transmission electron mi- croscopy TEM.RESULTS:Aften the Oncomelania hupensis snails were treated with SCS(8 μg/ml) for2 4h,cloudy swelling and coagulating necrosis of parenchyma cells of the hep- atopancreas,coagulating and dissolving changes in spermatogonia,cloudy swelling of the spermid membrane with isolating internal substance,aggregation of mitochondria,cloudy swelling of ova,deformity of ovum membrane and rupture of follicles were observed by TEM.CONCLUSION:SCS could damage the hepatopancreas and genital system of Oncome- lania hupensis.
