摘　　要：按常规方法，用透视电镜观察１８例星形细胞瘤、２例少树突胶质细胞瘤、２例髓母细胞瘤的超微结构。星形细胞瘤能清楚地区别出纤维型和原浆型星细胞；少树突胶质细胞瘤在光镜下疑为其他胶质细胞成分，在电镜下发现其基本结构还是少树突胶质细胞；髓母细胞瘤，其Ⅰ型细胞分化很低，Ⅱ型细胞则有一定程度分化。对３种胶质瘤超微结构的鉴别进行了讨论。Ultrastructure of 22 gliomas(18 astrocytomas, 2 oligodendrogliomas,and 2 medulloblastomas)was observed by transmission electron microscope (TEM).In astrocytomas,both the fibrous and protoplasmic astrocytes were found.Other glia cells of oligodendrogliomas were regarded under optis microscope,but their basement structure was oligodendrogliomas cell also by TEM observation.Ultrastructurally, medulloblastoma cells may be divided into type Ⅰand Ⅱ.The distinguish of these structure was discussed in this paper.
