摘　　要：东方次睾吸虫雌性生殖器官（卵巢、输卵管、卵黄－输卵管、卵模、梅氏腺和子宫）透射电镜 观察。卵巢内有不同成熟期的生殖细胞，成熟初级卵母细胞有几个靠近核的核仁样小聚体和许多沿 质膜的皮质颗粒。首次发现并描述卵巢和输卵管接合处（卵巢壶腹）的超微结构。输卵管上皮为纤 毛状。梅氏腺仅一种类型膜状小体细胞，经有微管支持的细小管道穿过卵模将膜状小体排入卵模腔 内。在卵黄－输卵管和卵模中有精子，卵模和子宫中有受精卵、虫卵（扫描电镜）：大小 ２６. ０５× １１．４６－１３．５５μｍ，卵盖直径６．２６－６. ８９μｐ，卵壳表面布满膜状隆起。文中对卵巢和梅氏腺的超微 结构特点进行了讨论。The female reproductive organ of Metorchis orientalis were studied by electron micro- scope. The ovary contains germ cells in various stages of maturation. Mature primary oocytes contain a few' nucleolus-like bodies' against the nucleus and numerous conical granules along the plasmalemma. The ultrastructure of ovary and oviduct junction (Ovarian ampulla) is first discovered and decribed. The epithelium of the oviduct is ciliated. Mehlis'gland contains only one type of membranous body cell with narrow cytoplasmic channels supported by microtube deliver thses mambranous body pass through the ootype wall and open into its luman. Sperm are present in the vitello-oviduct and the ootype, while the fertilized egg are present in the ootype and the uterus. The ovary, genital duct and Mehlis'gland are discussed.
