Аннотация
Activity of glutamine synthetase in the hepatocytes of healthy animals and animals with chronic CCl4-induced hepatitis was studied on white mature female rats after liver resection (15-20% of organ weight) and hyperbaric oxygenation (3 atm, 50 min, 3 times). Surgically operated left and non-operated middle lobes of the liver were analyzed on day 3 after liver resection and exposure to hyperbaric oxygenation. On day 65 of CCl4 poisoning, activity of glutamine synthetase decreased in both lobes and did not recover on day 3 after toxin cessation. Liver resection under conditions of CCl4-induced hepatitis restored reduced activity of glutamine synthetase in both liver lobes to the normal level. In healthy rats, the increase in glutamine synthetase activity after liver resection was found only in the middle lobe of the liver. Hyperbaric oxygenation enhanced the stimulatory effect of liver resection on glutamine synthetase activity in hepatocytes during chronic CCl4-induced hepatitis. In healthy animals with liver resection, activity of glutamine synthetase did not change after hyperbaric oxygenation, while normally oxygenation inhibited glutamine synthetase activity.
