[The effect of hypoxic hypoxia on energy metabolism in the liver mitochondria and the acetylcholine content of different tissues].
It has been found, the 1 or 2 days exposure of animals to hypoxic hypoxia (during 4 hours every day; 32 mm Hg) leads to the decrease of acetylcholine level in rat heart, liver and pancreas tissues and to activation of succinate oxidation in rat liver mitochondria. Beginning from the 7th day of hypoxia treatment the level of acetylcholine in the tissues was increasing and it was connected with the activation of NAD-dependent substrate alpha-ketoglutarate oxidation in the rat liver mitochondria and with the increase of the efficiency of oxidative phosphorylation. The effect increases to the 12-16-th day of animal adaptation. The important role of acetylcholine in formation of nonspecific adaptation reactions of organism to hypoxia has been shown.
