The interrenal and medullary cords as well as the blood vessels and connective tissue proportions in the adrenal glands of the male Nigerian fowl (Gallus domesticus) and guinea-fowl (Numida meleagris) were studied by microstereological techniques. Laying domestic fowl of the Rhode Island Red breed were entirely defeathered and maintained in a hot, humid pen for a period of three months, after which the adrenal glands were also studied microstereologically. Interrenal cord width was also measured in all the birds studied. The interrenal cords of the subscapular zone were consistently wider than those cords in the inner zone of the adrenal glands. This clearly suggested morphological zoning. The proportion of interrenal tissue was significantly greater in the guinea-fowl than in the Nigerian fowl, but the medullary tissue and the blood vessels and connective tissue were not significantly different. Interrenal hypoplasia or medullary hyperplasia occurred in the defeathered Rhode Island Red fowl as compared to the control birds of the same breed and sex. The significance of these findings is discussed.
采用微立体学技术研究了雄性尼日利亚家鸡（原鸡）和珍珠鸡肾上腺中的肾间组织和髓质索以及血管和结缔组织比例。将罗德岛红品种的产蛋家鸡完全拔毛，并在炎热潮湿的鸡舍中饲养三个月，之后也采用微立体学方法研究其肾上腺。还测量了所有研究鸟类的肾间索宽度。肩胛下区的肾间索始终比肾上腺内部区域的肾间索宽。这清楚地表明存在形态学分区。珍珠鸡的肾间组织比例显著高于尼日利亚家鸡，但髓质组织以及血管和结缔组织并无显著差异。与相同品种和性别的对照鸡相比，拔毛后的罗德岛红家鸡出现了肾间组织发育不全或髓质增生的情况。讨论了这些发现的意义。
