Oviductal epithelium of the baboon, Papio cynocephalus, was studied utilizing light, scanning, and transmission electron microscopy. Results of counts made of nonciliated, ciliated, and ciliogenic cells were analyzed statistically. The percentages of nonciliated cells of the fimbria and ampulla during the early proliferative and late secretory stages of the menstrual cycle were significantly greater than those during the mid-proliferative and late proliferative-early secretory stages, due to deciliation. This paper emphasizes previously unreported apical surface morphology as viewed by scanning and transmission electron microscopy. The microvillar pattern of the fimbrial secretory cells differs from that of the ampullar and isthmic cells in that the microvilli originate from thick apical protrusions and vary greatly in length and number as related to the cycle. A ridge demarcating the apical intercellular junction is composed of rows of microvilli during the early proliferative and late secretory stages. During the early proliferative and late secretory stages an increased degree of invagination of the basal and lateral plasma membranes occurs as the height and width of the cells decreases. The general numbers and distribution of the organelles of the various types of oviductal cells agree with that described for the ampulla and isthmus by Verhage et al. [(1990) Am. J. Anat., 187:81-90]; however, fimbrial epithelium was not included in that study. Other cyclic ultrastructural changes not examined previously include variation in the number of lipid droplets and their location, and in the number and relationships of glycogen particles to other structures.
利用光学显微镜、扫描电子显微镜和透射电子显微镜对狒狒（Papio cynocephalus）的输卵管上皮进行了研究。对非纤毛细胞、纤毛细胞和纤毛生成细胞的计数结果进行了统计学分析。由于纤毛脱落，在月经周期的早期增殖期和晚期分泌期，输卵管伞部和壶腹部的非纤毛细胞百分比显著高于增殖中期和增殖后期-早期分泌期。本文强调了通过扫描电子显微镜和透射电子显微镜观察到的以前未报道的顶端表面形态。输卵管伞部分泌细胞的微绒毛模式与壶腹部和峡部细胞不同，其微绒毛起源于粗大的顶端突起，并且其长度和数量与周期相关，差异很大。在早期增殖期和晚期分泌期，划分顶端细胞间连接的嵴由微绒毛排组成。在早期增殖期和晚期分泌期，随着细胞高度和宽度的减小，基底和侧质膜的内陷程度增加。各种类型输卵管细胞的细胞器的总体数量和分布与Verhage等人[（1990年）《美国解剖学杂志》，187:81-90]描述的壶腹部和峡部的情况一致；然而，该研究未包括输卵管伞部上皮。以前未研究过的其他周期性超微结构变化包括脂滴数量及其位置的变化，以及糖原颗粒数量及其与其他结构关系的变化。
