Certain Aspects of Human Metabolism during Spaceflights of Varying Duration

摘要

A comparative analysis is made of hormone reactions after short and long term spaceflights. Endocrinological indicators from venous blood and daily urine samples of cosmonauts completing flights lasting from 7 to 237 days were examined. No pathological indicators were found in the metabolic shifts in the erythrocytes and disruption of the functional state of their membranes.
