[Role of tissue glycolysis in combined exposure to hypercapnia, hypoxia and hypothermia].

The amount of metabolites of the glycolytic way of carbohydrates transformation and the enzymatic activity were studied in the tissues of brain, myocardium, liver, skeletal muscles, and the blood serum of rats subjected to cooling in conditions of gradually increasing concentrations of CO2 and decreasing concentrations of O2. Single as well as repeated actions of these factors entailed changes of the substrates under study and of some enzymatic activity which revealed a moderate intensification of the glycolysis within the general rearrangement of metabolism during adaptation to sharp hypoxia under the above conditions.
