人五鞭毛滴虫超微结构的进一步观察

透射电镜观察人五鞭毛滴虫前部有一椭圆形的细胞核，其背侧可见一条肋及由副基体和两根副基纤维组成的副基器。核的前方有由鞭毛周管、Ｃ形盾和６个毛基体组成的毛基体复合体。由毛基体分别发出４根前鞭毛，１根独立前鞭毛和１根后鞭毛。轴柱位于核的腹侧，分头、干和尾三部分。轴头起自盾－轴连合，开始是匙形，围绕于核的腹侧，延伸至核后端时，卷曲成筒状为轴干，最后以轴尾伸出体外。波动膜乃虫体细胞膜和细胞质向虫体背侧延伸形成的一条波浪形膜结构，向后直达虫体末端。该膜的细胞质内有一电子密度增大的板层结构。后鞭毛伴行于波动膜左侧，至虫体末端离开波动膜，游离于体外。

A FURTHER STUDY OF ULTRASTRUCTURE OF PENTATRICHOMONAS AS REVEALED BY ELECTRON MICROSCOPY

The oval nucleus of Pentatrichomonas hominis was situated in the anterior part of the body. Except a costa in the back of nucleus, a parabasal apparatus could be seen which was cosisted of one parabasal body and two parabasal filaments. At the anterior end of cell it had a blepharoplast complex which was consisted of three part, periflagellar canal,C-shaped pelta and six blepharoplasts. Four anterior flagella, one independent anterior flagellum and one posterior flagellum were extended respectively from their blepharoplasts.The axostyle was divided into three parts, capitulum, trunk and caudal. The spoon-shaped axostylar capitulum was originated from the peltar-axostylar junction. The undulating membrane was a wave-like membraneous structure extending outside the body from the cytoplasm and cell membrane at the dorsal surface of the organism. The cytoplasm of undulating mombrane contained a centrally located marginal lamella. The posterior flagellum was extending towards the posterior end of cell along the left side of undulating membrane and then freed out of the membrane.
