The effect of hypoxenum on bioenergetic processes in heart and liver mitochondria of rats, connected with respiration, the generation of hydrogen peroxide, and the activity of ATP-sensitive K-channel ((mitoK)ATP) has been studied. It was shown that hypoxenum in the concentration range of 0.05-10 microg/ml stimulates respiration, increases the coupling in the respiratory chain, and enhances the formation of H2O2 and energy-dependent swelling associated with potassium transport in mitochondria. Hypoxenum removes the inhibitory effect of ATP on the energy-dependent swelling of mitochondria and partially reduces the accumulation of H2O2 in the presence of ATP. The role of antihypoxic and antioxidant action of hypoxenum associated with the activation of (mitoK)ATP is discussed. |
