title: [Acid-base equilibrium and nitrogen metabolism in rats in a state of artificial hibernation].
abstract: Experiments on rats have shown an important role of hypercapnia in the development of condition of artificial hibernation in combination with influence of hypothermia, hypoxia and hypercapnia. It is proved that the joint action of hypothermia, hypoxia and hypercapnia has induced development of respiratory acidosis and hibernation in animals, while removal of the hypercapnia effect has induced development of acute metabolic acidosis and death of animals. It has been found that animals in the state of artificial hibernation have considerable changes in concentrations of main electrolytes (Na+, K+, Ca+, Mg2+, phosphates, Cl-) and metabolites (NH3, glutamine, urea) in blood as well as in activity of enzymes (glutamaldehydrogenase, glutaminase, arginase) in tissues of the liver and kidneys.
