Histological and Histochemical Studies of the Post-ovulatory Follicles during the Annual Reproductive Cycle Including Nesting Cycle of a Wild Avian Species, the Pied Myna, Sturnus Contra Contra L.

本文報告印度野生鳥燕八哥在年週期與築巢週期排卵後濾泡之研究。以生殖週期五月份之交配期之濾胞為研究對象。以組織學觀察該等濾胞萎縮過程，可分為四階段。第一及第二階段是在產蛋期，而第三及第四階段是在築巢週期的孵蛋期。在幼雛期間之母鳥，其濾胞大小或數目急遽減少。濾胞顆粒狀層及內莢膜層細胞內之3-β羥類固醇去氫酶活性，在萎縮過程之第一階段為強烈，而在第二、三、及四階段則減弱。另一方面，濾胞之兩層細胞之嗜蘇丹染料反應，在第一階段為微弱，而二、三、及四階段則增強

The post-ovulatory follicles were studied during the annual reproductive cycle and nesting cycle of the pied myna, Sturnus contra contra. These follicles were observed during the breeding phase (May) of the reproductive cycle. Histologically, they were found to regress in 4 stages. Stages I and II were found in the egg-laying period, whereas Stages III and IV were observed in the incubation period of the nesting cycle. The follicles were drastically reduced in the nestling period. 3β-HSDH activity, present in both granulosa and theca interna of the follicles, was intense during the initial regression Stage (I) and decreased subsequently (Stages II, III and IV). On the other hand, sudanophilic lipid reaction, localized in both layers of the follicles, was weak in Stage I but increased in subsequent Stages (II, III and IV). The findings are briefly discussed.
