绵羊发情期输卵管组织结构的观察

采用冰冻切片、H.E染色,对绵羊发情期输卵管各部进行了组织学观察和研究.结果表明,在发情期,绵羊榆卵管伞、漏斗部和壶腹部纵行皱褶黏膜上皮的厚度稍有增加,并且黏膜上皮向固有膜下陷形成一些输卵管腺;腺泡上皮为不太规则的假复层纤毛柱状上皮,由大量分泌细胞和少量的柱状纤毛细胞、基细胞共同构成;输卵管伞、漏斗部和壶腹部,黏膜上皮和腺泡上皮内大部分分泌细胞顶端出现有分泌小泡,而在榆卵管峡部,分泌细胞顶端则没有分泌小泡.绵羊发情期,输卵管伞、漏斗部和输卵管壶腹部在固有膜内出现有榆卵管腺,分泌细胞顶端出现有分泌小泡;峡部的输卵管腺与其他部位的输卵管腺在形态结构和分泌方式上明显不同.

Observation of Histological Structure of Oviduct in Sheep during Estrous Period

The histological structure of oviduct in sheep during estrous period was observed by using the frozen section and H. E dying. The results showed that during estrous, the thickness of longitudinal folds in mucosal epithelium of the fimbriae, infundibulum,and ampulla of sheep's oviduct were incrassate little bit, and the mucosal epithelium fell into lamina propria formed some oviduct glands. The gland epithelium was irregular pseudo-stratified ciliated columnar epithelium which consist a lot of secretory cells, fewer ciliated columnar cells, and basilar cells. There were secretory bubbles on top of many secretory cells in the mucosal and gland epithelium of the fimbrea, infundibulum,and ampulla of oviduct, but not on top of the secretory ceils of the oviduct isthmus. Oviducal glands were found in the lamina propria of the fimbria, infundibulum, and ampulla of the oviduct, the secretory bubbles were found at top of the secretory cells in sheep during the estrous period. The morphological structure and secrete mode of oviducal glands in isthmus was different with others places in the oviduct.
