Ultrastructural Changes of Seminiferous Tubules in the Mouse by Alkylating Agent

Alkylating Agent에 의한 Mouse 정세관의 미세구조 변화

The purpose of this study was to investigate the effect of cyclophosphamide on the mouse seminiferous tubules by transmission electron microscopy at different groups: a control group, a group treated one time a week, and a group treated two times a week. Cyclophosphamide was injected in the intraperitoneal at a dosage of level 200mg/kg. The results obtained were as follows. 1. In the group of one time a week, pyknotic body and large vesicles were observed in cytoplasm of spermatogonium of seminiferous tubules, and in the intercellular space between spermatocytes, respectively. 2. In the group of two times a week, nucleus envelope in the spermatid was disrupted partially, observed vesicles in the nucleoplasm of spermatid, and separated or disrupted inner and outer membranes of mitochondria in the Sertoli cells.
