INDICATORS OF OXYGEN ABSORPTION IN TESTICULAR TISSUES UNDER THE INFLUENCE OF INCORPORATION 137CS

The results of assessing the effect of caesium-137 radionuclide, with a specific activity of 3300 Bq/kg, on oxygen consumption by rat testicular tissues. A significant increase in the rate of oxygen consumption was demonstrated on both endogenous and exogenous substrates. The maximum increase in tissue respiration was noted against the background of the use of glutamate as an exogenous substrate. Signs of disconnection of oxidative phosphorylation processes with the use of 2,4-dinitrophenol have been recorded, as well as inhibitory analysis confirms a decrease in the intensity of NAD-dependent oxidation Thus, the oral intake of caesium-137 into the body of rats with a specific activity of 3300 Bq / kg poses a danger to the male reproductive system.
