小鼠细粒棘球蚴不育囊的超微结构观察

OBSERVATION ON ULTRASTRUCTURE OF STERILE CYSTS OF ECHINOCOCCUS GRANULOSUS IN MICE

用透射电镜观察了小鼠细粒棘球蚴不育囊的超微结构。其囊壁由角皮层和生发膜构成,角度层含有纤维基质和不规则形颗粒,生发膜又可分皮层区和细胞区。在皮层区基部见到线粒体,微毛间见到“吞饮泡”样质膜凹陷;在细胞区主要有皮层细胞、肌细胞、含糖原细胞等,在有的含糖原细胞中还见到“核仁管系统。”

The fine structure of sterile cysts of Echinococcus grcnulesus in mice was atudied by TEM.The cyst wall consists of laminated layer and germinal membrare At (?) level,the laminated layer contains microfibrillate matrix and irregularly shaped electron-dense granules.The germinal membrane comprise of tegument and cell region.Plasmalemma invagination resembling the 'pinocytotic vesicle' are seen between the microtriches of the tegument,and mitochondria are seen in the basal portion of the tegument.In the cell region,there are tegumental cells,muscle cells,and glycogen-contafning cells.'Nucleolar channel system' can be observed in some of the glycogen-containing cells.
