Abstract: The experimental researches have shown, that the application of hyperbaric oxigenation (HBO, 3 bar, 50 min, 1 session per day) during the first three after resection of 15-20% mass of liver at healthy animal liquidates violations of glutamine metabolism caused by operational aggression. As a results there is a dominance of glutamine formation above its decay that is exhibited by accumulation of glutamine and glutamate by cells of liver on a background of normalization 0f a boosted content of ammonia in them. The proximity of hepatocytes to the center of mechanical destruction of tissue determines not only a glutamate concentration increasing degree at hyperoxia but also dynamics of glutamine synthase and phosphate-dependent glutamines activity in early and late posthyperoxic phase.
