Abstract
The isoenzyme composition of lactate dehydrogenase of soleus and plantaris muscles of rats flown for 20.5 d aboard the biosatellite Cosmos-690 and irradiated with a dose of 800 rad was investigated. The muscles exposed to weightlessness per se and weightlessness combined with radiation showed similar changes in their carbohydrate metabolism. On return to 1 G, readaptation of irradiated rats developed less rapidly than of animals exposed to weightlessness alone.
摘要
研究了搭载在生物卫星“宇宙-690”上飞行20.5天并接受800拉德剂量辐射的大鼠比目鱼肌和跖肌中乳酸脱氢酶的同工酶组成。暴露于失重本身以及失重与辐射相结合环境下的肌肉，其碳水化合物代谢呈现出相似的变化。返回1G环境后，受辐射大鼠的重新适应过程比仅暴露于失重环境的动物发展得更慢。
