After short-term (7-day) space flights the following parameters were measured in blood of cosmonauts: cortisol, ACTH, aldosterone, thyrotropic hormone, thyroxine, triiodothyronine, somatotropic hormone, insulin, testosterone, cyclic nucleotides, prostaglandins, activities of the kallikrein-kinin, fibrinolytic and coagulatory systems, and plasma renin activity; in addition, renal excretion of aldosterone and total 17-oxycorticosteroids was determined. It was demonstrated that after the short-term flights the acute period of adaptation was accompanied by a moderate activation of the renin-angiotensin-aldosterone system, adrenal glucocorticoid function, pancreatic insular apparatus, kallikrein-kinin system as well as increased cyclic AMP which is suggestive of a moderately expressed stress-reaction. |
