应用透射电镜和扫描电镜观察了日本血吸虫（Ｓｃｈｉｓｔｏｓｏｍａｊａｐｏｎｉｃｕｍ）未成熟虫卵卵壳的超微结构。初产期和胚胎期虫卵卵壳形态结构相似，均有形态多样的微管道贯通卵壳内外，管道内含一些分泌颗粒，管壁由单位膜构成；致密的微棘沿卵壳均匀分布，微棘纵切呈长三角形，横切呈星形，中央有小空腔；卵壳由电子密度低且较厚的外层和电子密度高且较薄的内层构成；卵壳表面有丰富的网样纤维基质。推测卵壳的微管道、微棘和网样纤维基质的形成时期是同步的，皆在雌虫卵模内形成。本文讨论了微管道的结构、功能与意义。
The ultrastructure of egg eggshell of Schistosoma japonicum was observed by transmission electron microscopy and scanning electron microscopy. Early embryo and embryo egg egg shell morphological similarities, there are various forms of micro-pipelines through the inside and outside the egg shell, the pipe contains some secretory granules, the wall consists of unit membranes; dense micro-spines are evenly distributed along the egg shell, Micro-spines are longitudinally triangular, transversal and star-shaped, and have small cavities in the center. The egg shell consists of an outer electron-dense and thick outer layer and an inner electron-dense and thin inner layer. The surface of the egg shell is rich Web-like fiber matrix. Speculated eggshell microtubules, micro-spines and mesh-like fibrous matrix formation period is synchronized, are formed in the female egg mold. This article discusses the structure, function and significance of micro-pipes.
