[Seasonal changes of corticosteroid content in practically healthy young persons under condition of monsoon climate of Khabarovsk].

In 195 apparently healthy young men, residents of Khabarovsk, a study was made of the contents of the sum total 11-OCS, corticosteroids--free and protein-bound, cortizol and corticosterone in the blood plasma, and 17-OCS in the urine, depending on the season of the year, climatic and weather factors. Seasonal changes of glucocorticoid function of the adrenal cortex with the maximal plasma hormone level during winter and their greatest urinary excretion during summer were found. An increase of free (biologically-active) corticosteroid fraction was recorded during bad weather at all the seasons.
