The article deals with oxidation of different substrates, intensity of glycolytic and glycogenolytic processes in mitochondria and homogenates of dog liver with its 2-hour exclusion from circulation under conditions of endotracheal ether-oxygen narcosis. It was established that already 30-60-minute ischemia causes a decrease in intensity of succinate, alpha-ketoglutarate oxidation and acceptor respiration, inhibiton in the activity of the citrate cycle enzymes; succinate dehydrogenase, alpha-ketoglutarate dehydrogenase, isocytrate dehydrogenase. The activity of NAD-dependent malate dehydrogenasedehydrogenase and Mg2+-ATPase as well as intensity of NADN oxidation in mitochondria increase. After 2-hour ischemia the activity of Mg2+-ATPase, cytochrome oxidase and peroxidase lowers. A sharply developed glycogenolysis is accompanied by inhibition of phosphorylase activity and a two-fold stimulation of the glycolytic reactions. Peculiarities in regulation of enzymatic reactions under conditions of ischemia and their role in origin of metabolism disturbances in the liver are under discussion.
