The antihypoxic effect of the Nepeta multifida L. dry extract was studied in experiments on white Wistar rats. The life span of animals was determined against the background of acute hypoxias: hypercapnic, hemic, and histotoxic ones. Using the model of acute hypobaric hypoxia/reoxygenation there was evaluated the content of ATP, lactic and pyruvic acids, TBA-active products, reduced glutathione, catalase activity in brain tissue. On the model of acute hypobaric hypoxia/reoxygenation, the content of ATP, lactic and pyruvic acids, reduced glutathione and catalase activity in brain tissue The N. multifida dry extract demonstrated antihypoxic effect at the doses comprised between 100 and 300 mg/kg increasing lifespan of animals in hypercapnic, hemic and histotoxic hypoxias. N. multifida decreases the manifestation of free-radical oxidation processes, increases the activity of the endogenic antioxidant system, and promotes the efficacy of tissue respiration and oxidative phosphorylation coupling in the brain of white rats in hypoxia/reoxygenation.
