Abstract

The structural organization of adrenal cortex has been studied in intact rats and after short-term hypoxia exposure on different altitudes (2, 6, 8, 11 km). Previously rats have been divided into 3 groups by adrenaline test for determining of vegetative reactivity type. It has been found that some histochemical and morphometric indices of adrenal cortex had peculiarities with respect to type of vegetative reactivity (width of zones, their ratio, nuclear diameter, ascorbic acid content and its distribution and other) in intact rats. Under altitude these differences form individual character of steroidogenesis and determine resistance and reactivity of organism.

摘要

在完整大鼠以及在不同海拔高度(2、6、8、11千米)短期缺氧暴露后,对肾上腺皮质的结构组织进行了研究。此前,通过肾上腺素测试将大鼠分为3组,以确定植物性反应类型。研究发现,在完整大鼠中,肾上腺皮质的一些组织化学和形态测量指标在植物性反应类型方面存在特殊性(各带宽度、它们的比例、核直径、抗坏血酸含量及其分布等)。在高海拔条件下,这些差异形成了类固醇生成的个体特征,并决定了机体的抵抗力和反应性。
