摘　　要：目的 :了解钉螺体表经茶树籽浸液作用后的损害状况。方法 :应用扫描电镜比较观察正常钉螺与感染钉螺受茶树籽作用后的体表病损。结果 :浸渍过茶树籽的钉螺头部体表出现大块组织脱落缺损及变形 ,足部体表增厚 ,出现皱褶变化和大量细胞浸润 ,外套膜前端边缘变粗糙 ,皱褶间有缺损及细胞浸润 ,整个边缘比正常的肿大 ,复盖肝脏部位的内脏囊外形由于较深陷的沟回出现 ,可见凹凸相间的皱褶。结论 :茶树籽浸液能损伤钉螺软体体表结构。AIM:To observe the lesion of tegument of Oncomelania snails treated with seed of Camellia Sinensis(SCS) .METHODS:Using scanning electron microscopy for observation of damage in the tegument of normal and infected Oncomelania snails treated with SCS.RE- SUL TS:Tegument of head in drug treated snail showed serious damage and deformity.Part of snail foot was thickened and wrinkled,infiltrated with numerous cells.Fine and soft mi- crofilament tissue in the lateral border of mantle in normal Oncomelania snails were demon- strated.After exposure to the drug,normal tissue of mantle was destroyed.The visceral sac at liver site in infected snail showed severe damage(Figs.1 - 1 4) .CONCLUSION:The tegu- ment of soft tissues of Oncomelania hupensis would be damaged by SCS.
