Abstract
In an experiment with seven-day immersion, blood samples were taken from eight volunteers (21 to 26 years old) seven days prior to immersion, on days 3 and 7 of immersion and on days 1 and 8 of recovery. Blood serum was analyzed for 38 biochemical markers of the functional state of the myocardium, skeletal muscles, hepatobiliary system, kidneys, pancreas, gastrointestinal tract, prostate, and protein-nucleic, carbohydrate, electrolyte, and mineral metabolisms. Seven-day immersion was shown to alter the biochemical parameters within the range of the physiological norm. The observed changes included lower activities of enzymes associated with muscular and myocardial constellation, shifts in electrolytes (K, Na, Mg), and an increase in the biliary function parameters. Increased concentrations of the parameters of lipid metabolism suggest a higher risk of atherogenesis. Biochemical parameters of bone tissues and erythrocyte activity were practically unchanged. Most of the parameters returned to the preexperimental values by day 8 of recovery.
