A morphological and histochemical study has been made of ovarian surface epithelium during the sexual cycle of seasonally breeding birds: crow (Corvus splendens) and common myna (Acridotheres tristis). The surface epithelium is composed of a single layer of compactly arranged columnar and flat cells in the quiescent ovary. It develops numerous villi during the breeding season. The formation of villi has been correlated with the proliferation of cells which are subsequently incorporated into the ovarian stroma where they appear to form follicle and thecal cells around the growing oocytes as evidenced by the close similarities in the morphological and histochemical characteristics of these cell types. As the ovarian activity increases, the surface epithelial cells show increasing amounts of RNA and proteins, which are indicative of their rapid multiplication. No lipids and enzyme activities of acid and alkaline phosphatases, ATPase. DPN- and TPN- diaphorases and delta5-3beta HSDH have been detected in the surface epithelium of both quiescent and active ovaries.
对季节性繁殖鸟类（乌鸦（Corvus splendens）和家八哥（Acridotheres tristis））性周期中的卵巢表面上皮进行了形态学和组织化学研究。在静止卵巢中，表面上皮由单层紧密排列的柱状和平扁细胞组成。在繁殖季节，它会形成大量绒毛。绒毛的形成与细胞增殖相关，随后这些细胞融入卵巢基质，在那里它们似乎围绕生长中的卵母细胞形成卵泡和卵泡膜细胞，这些细胞类型在形态学和组织化学特征上的密切相似性证明了这一点。随着卵巢活动增加，表面上皮细胞显示出越来越多的RNA和蛋白质，这表明它们在快速增殖。在静止和活跃卵巢的表面上皮中均未检测到脂质以及酸性和碱性磷酸酶、ATP酶、DPN-和TPN-黄递酶和δ5-3βHSDH的酶活性。
