title: Changes of corticosteroid spectrum in urine in members of crew of spaceship "Soyuz-22".
abstract: The urinary excretion of 17-hydroxycorticosteroids and the relations between the glucocorticoids in urine and their precursors as well as between 17-hydroxycorticoids and 17-hydroxycorticoids and 17-dehydroxycorticosteroids was measured in two subjects before and after 8 days flight in spaceship "Soyuz-22". During a readaptation period after the space flight activation of the glucocorticoid function of adrenals was observed which was accompanied by signs of stress and relative deficiency of 11-hydroxylation in glucocorticoid synthesis. The assumptions on possible causes of observed changes are discussed.
