The following experiments were performed to study the morphology of the adrenals of male rhesus monkeys: six monkeys were exposed to clinostatic hypokinesia for 7 days and then to head-down tilt at -6 degrees for 12 days; two monkeys were exposed only to head-down tilt for 7 days and 5 monkeys were used as controls. The adrenals exhibited changes of three types: stress-reaction manifestations, activation of the glomerular area of the cortex, and synchronization of the medullary matter to noradrenaline production. All these changes reflect adaptive reactions of the animal body to head-down tilt.
6只猴子先接受7天的卧床低动力状态,然后以-6度头低位倾斜12天;2只猴子仅接受7天的头低位倾斜,5只猴子作为对照。肾上腺呈现出三种类型的变化:应激反应表现、皮质球状带激活以及髓质物质与去甲肾上腺素产生同步。所有这些变化反映了动物体对头低位倾斜的适应性反应。
