绿蟾蜍繁殖期间输卵管变化的组织学研究

OBSERVATION ON THE HISTOLOGICAL CHANGES OF OVIDUCT OF BUFO VIRIDIS DURING REPRODUCTIVE PERIOD

本文研究了绿蟾蜍繁殖期间输卵营组织结构变化的规律。产卵前，输卵管壁最厚，固有层中的单管状腺充满胶质；产卵时，粘膜层形成细长的皱襞，固有层中的腺体分泌胶质，形成包裹卵子的卵胶膜；产卵后，输卵管壁变薄，腺体细胞缩小，但腺体间的结缔组织隔膜增厚，结缔组织可能对腺体细胞的修复起重要作用。

The histological changes of the oviduct in Bufo uiridis in the duration of reproduction were studied in May, 1989. The structure of the oviduct consists of mucous opithelium, lamina propria and serosa. Before ovulation, the oviducal wall is very thick and the simple tubular glands in lamina propria are filled with the jelly substances. During ovulation, the mucous epithelium forms a lot of folds and the glands in lamina propria secretes the jelly which packs the eggs. After ovulation, the oviducal wall is thinner, the cells of the tubular glands becomes smaller and the connective tissues around the glands are changed into thicker: The fuction of the connective tissues may play a role in regeneration of the oviduct.
