The paper presents the results of studying the fluid-electrolyte metabolism in P. I. Klimuk and V. I. Sevastyanov before and after their 63-day flight aboard the orbital station Salyut-4. Postflight weight losses in P.I. Klimuk and V.I. Sevastyanov were 5.6 and 3.5%, respectively, the losses being attributed to body dehydration. Postflight both cosmonauts showed a trend for an increased renal excretion of potassium, magnesium, and calcium as compared with their food intake. Those were more expressed on the day after the water load application. Possible causes of the changes and the pattern of recovery of fluid-electrolyte metabolism after a prolonged space flight are discussed.
本文介绍了对P. I. 克利姆库克和V. I. 谢瓦斯季亚诺夫在搭乘“礼炮-4”号轨道站进行63天飞行前后的体液电解质代谢研究结果。P. I. 克利姆库克和V. I. 谢瓦斯季亚诺夫飞行后的体重减轻分别为5.6%和3.5%，体重减轻归因于身体脱水。飞行后，与食物摄入量相比，两名宇航员均呈现出肾脏对钾、镁和钙排泄增加的趋势。在饮水负荷试验后的第二天，这种趋势更为明显。文中讨论了这些变化的可能原因以及长时间太空飞行后体液电解质代谢的恢复模式。
