摘要
本文对土耳其斯坦东毕吸虫结节变种尾蚴皮层的超微结构进行了描述。尾蚴皮层从外向内由糖蛋白膜、外质膜、皮层基质、基质膜、基底膜组成。皮层基质为一较厚的致密层,无细胞界线及其它亚细胞结构,充满致密的细颗粒性物质。此层厚度变化较大,而致虫体表面凸凹不平。有两型致密体分布于皮层基质中。
Through transmission electron microscope,the ultrastructure of the tegument of Orien-tobilharzia turkestanica var. tuberculata cercariae was observed. From exterior to interior, the tegument can be divided into five parts,i. e. ,glycocalyx,external plasma membrane,ma-trix, basal plasma membrane and basement layer. The cell boundery is absent in the matrix, there is no subcellular structure but is filled with abundant dense particles. The thickness of this layer varies markedly so the surface of the cercarial body can be either convex or con-cave. There are two types of dense bodies (cercarial-type inclusion bodies) in this layer. Its formation,function and the relation with the glycocalyx are discussed.
