[Enzyme activity and content of glycerophosphate shuttle metabolites in the cortex and medulla oblongata during hyperbaric oxygenation therapy of acute hemorrhage].

The experiments on cats have demonstrated that hyperbaric oxygenation (303.9 kPa, 60 min) in acute blood loss (24.0 +/- 0.8 ml/kg) has an essential effect on glycerophosphate shuttle mechanism: it stimulates mitochondrial glycerol-3-phosphate dehydrogenase in the sensorimotor cortex and medulla oblongata, providing glycerol-3-phosphate dehydrogenation, activates cytoplasm hydrogen delivery to mitochondrial respiratory chain, prevents glycerol-3-phosphate and NADH level increase and cytoplasm glycerol-3-phosphate dehydrogenase inhibition, limiting lactate production.
