[Anaerobie glycolysis and resistance to oxygen starvation in rabbits and white rats].

In rabbits and albino rats, studies have been made on the resistance to high altitude hypoxia and acute blood loss, the rate of anerobic glycolysis and the activity of some enzymes of energy metabolism. It was shown that as compared to rabbits, the rats are more resistant to hypoxia, but less resistant to acute blood loss. Higher resistance of rats to hypoxia is due to the 1.5 times rate of anaerobic glycolysis in their brain as compared to that of rabbits. Their lower resistance to the blood loss is associated with the fact that the rate of anaerobic glycolysis in the heart of rats is 8 times lower. It is concluded that the resistance to high altitude hypoxia depends mainly on the anaerobic metabolism of the brain, whereas tia depends mainly on the anaerobic metabolism of the brain, whereas the resistance to acute blood loss depends mainly on the anaerobic metabolism of the heart.
