The luminal surfaces of epithelial cells in various regions of the oviducts of the goats at the follicular and luteal phases of the oestrous cycle were examined by scanning electron microscopy. Marked cyclic changes were observed on the surface of the epithelium in the fimbriae, ampulla and ampullar-isthmic junction, but few changes were found in the isthmus or uterotubal junction. The epithelium of the fimbriae, ampulla, and ampullar-isthmic junction of oviducts in the follicular phase was extensively ciliated and most of the cilia extended above the apical processes of the nonciliated cells. In the luteal phase, many ciliated cells were hidden by the bulbous processes of the nonciliated cells. In the isthmus and at the uterotubal junction, the apical surfaces of the nonciliated cells were flat or gently rounded at both phases of the oestrous cycle. The results demonstrate that regional variations are associated with the cyclic changes in the epithelial cells of the goat oviduct.
在发情周期的卵泡期和黄体期，通过扫描电子显微镜检查了山羊输卵管各区域上皮细胞的管腔表面。在输卵管伞、壶腹部和壶腹-峡部连接处的上皮表面观察到明显的周期性变化，但在峡部或子宫-输卵管连接处几乎没有变化。卵泡期输卵管伞、壶腹部和壶腹-峡部连接处的上皮有广泛的纤毛，大多数纤毛伸出非纤毛细胞的顶端突起之上。在黄体期，许多纤毛细胞被非纤毛细胞的球状突起所掩盖。在峡部和子宫-输卵管连接处，非纤毛细胞的顶端表面在发情周期的两个阶段均为扁平或轻度圆形。结果表明，区域差异与山羊输卵管上皮细胞的周期性变化有关。
