RESEARCH OF THE FUNCTIONS OF THE EXTRACTIVE SYSTEM OF DIVIDERS UNDER THE CONDITIONS OF TOXIC ACTION OF OXYGEN
Aim: The purpose of the study was to identify changes in renal function under the action of dosed hyperoxia using preoral stress renal tests; to determine the relationship between the state of the functions of the excretory system and the body's resistance to the toxic effect of oxygen. Material and methods. A survey of 44 men aged 19-23 years was conducted. All subjects were evaluated initial resistance to the toxic effects of oxygen according to standard methods. Changes in water-electrolyte metabolism and renal function were determined using the developed preoral stress renal tests. The first series of studies is anpreoral water load in a dose of 20 ml/kg body weight. The second series of studies is anpreoral load of 0.5 % sodium chloride at a dose of 0.5 % by weight. The third series of studies - anpreoral load of 10 % potassium chloride solution, at a dose of 0.55 ml/kg body weight. The fourth series of studies is anpreoral load of 7.5 % calcium lactate solution, at a dose of 1 ml/kg body weight. Conclusion and conclusions. Persons who have low and medium resistance to the toxic effects of oxygen, after anpreoral water load and a load of sodium chloride, have a decrease in the amount of urine, sodium and chlorine. For subjects with high resistance to the toxic effects of oxygen, increasing of excretion of potassium and chlorine after loading with a solution of potassium chloride and lactate calcium is the main characteristic.
