[The state of energy metabolism in the rat liver after a single acute hemorrhage].

A system of adenine nucleotides and redox state of liver cells as well as activities of dehydrogenases of the tricarbonic acid cycle and of cytochrome oxidase in liver cell homogenates were not altered after an acute single hemorrhage in rats even though the process run into the step of circulation decompensation (AP 40 mm Hg).

[Tissue respiratory enzymes in the rat liver in acute blood loss].

An increase in activity of several dehydrogenases of tricarboxylic acid cycle (NADP-dependent malate dehydrogenase, alpha-ketoglutarate dehydrogenase) was observed in rat liver tissue under conditions of acute hemorrhage. The enzymatic activity was slightly higher in the group of animals with relatively prolonged life-time as compared with those, which lived less than 4 hrs. Activity of cytochrome oxidase was inhilited in the both groups of animals (by 27% and 29%, respectively).
