棉鼠丝虫的组织学观察

应用常规的组织学方法，观察了棉鼠丝虫的显微结构。棉鼠丝虫雄虫的角皮及体肌均较雌虫的为厚，假体腔亦以雄虫的为大，对两性成虫的生殖器官进行了详细的描述或测量。雄虫生殖器官由睾丸、输精管及贮精囊组成，睾丸内含精原细胞、精母细胞、精子细胞及精子。雌虫生殖器官包括卵巢、输卵管、子宫及肌性阴道，卵巢内有卵原细胞、卵母细胞及成熟卵细胞，子宫内含有从卵细胞至成熟微丝蚴的各发育期胚胎，消化道的管腔较两性成虫生殖道的为窄。了解正常棉鼠丝虫组织学的结构，对药物作用于成虫及幼虫机制的探讨有一定的意义。

HISTOLOGICAL OBSERVATIONS ON LITOMOSOIDECARINII

The microscopical structures of L. carinii were studied by routine histological methods. Both cuticle and ceolomyarian musculature of male worm were thicker than that of female's. The pseudo body cavity was also larger in male worm.The reproductive organ of both sex were described and measured in detail. The male genital organs consisted of testis, vasde ferens. and spermatheca. spermatogonia. spermatocyte. spermatid and spermatozoa presented in testis. The female genital organ included ovary, oviduct. uterus and muscular vagina. There were oogonium. oocyte, and mature ootid in the ovary and all developing stages of embryos.farm ovum to mature microfilaria were found in uterus. The lumen of digestive tract was more narrow than that of reproductive ducts in both sex.To know the normal histological structure of L. carinii was helpful in researching the mechanism of drug effects on both adult and larvae forms.
