    Abstract:
    Blood samples were taken from 8 volunteers (21 to 26 years of age) for 7-day immersion 7 days prior to, on days 3 and 7 of the experiment and on days 1 and 8 of recovery. Serum was analyzed for 38 biochemical markers of the functional state of the myocardium, skeletal muscles, hepatobiliary system, kidney, pancreas, GI tract, prostate, and protein-nucleic, carbohydrate, electrolyte and mineral metabolism. Seven-day immersion was found to alter the biochemical parameters within the physiological norm boundaries. The observed changes included lower activities of enzymes associated with muscular and myocardial constellation, shifts in electrolytes (K, Na, Mg), and increases in the biliary function parameters. Increased concentrations of the lipid metabolism parameters suggest a higher risk of atherogenesis. Biochemical parameters of bone tissues and erythrocyte activity were essentially unchanged. Most of the parameters returned to pre-experimental values by day 8 of recovery.
