Adrenal glands of eight Indian species of birds, namely Columba livia, Passer domesticus, Corvus splendens, Acridotheres tristis, Acridotheres ginginianus, Milvus migrans, Francolinus pondicerianus and Bubulcus ibis were examined during the sexually active and inactive phases of their annual reproductive cycles. Excepting A ginginianus and M. migrans, among members of either sex of the remaining six species the weight of the adrenal gland increases during the period of sexual activity. Histologically, the interrenal tissue of these birds could be divided into a peripheral subcapsular zone and a central zone. The cytochemical content of these two zones varies between sexual activity and inactivity. In sexually active birds of both sexes, interrenal cells of the central zone exhibit an increased concentration of alkaline phosphatase, glycogen, acid mucopolysaccharides and gross lipids, while in the subcapsular interrenal cells there is a prominent increase of ascorbic acid content. Cytochemical contents of chromaffin cells remain unchanged except acid phosphatase, which increases during the sexually active phase.
在八个印度鸟类物种的年度繁殖周期的性活跃期和非活跃期，对其肾上腺进行了检查，这八个物种分别是家鸽、家麻雀、大嘴乌鸦、家八哥、丛林八哥、黑鸢、灰鹧鸪和牛背鹭。除了丛林八哥和黑鸢，其余六个物种的雌雄个体中，肾上腺重量在性活跃期都会增加。从组织学上看，这些鸟类的肾上腺组织可分为外周的被膜下区和中央区。这两个区域的细胞化学含量在性活跃期和非活跃期有所不同。在雌雄两性的性活跃鸟类中，中央区的肾上腺细胞中碱性磷酸酶、糖原、酸性粘多糖和总脂质的浓度增加，而被膜下肾上腺细胞中的抗坏血酸含量显著增加。嗜铬细胞的细胞化学含量除酸性磷酸酶外保持不变，酸性磷酸酶在性活跃期增加。
