METOVITAN INCREASES THE RESISTANCE OF THE BODY TO HYPOXIA

Aim. To study the efficacy of the vitamin preparation Metovitan and multivitamin preparation Decamevit in preventing the development of oxidative stress in the development of oxidative stress in rat tissues and their survival under hypoxic hypoxia. Methods. Experiments were performed on Wistar rats, 160-220 g. A model of hypoxic hypoxia was induced by lifting the rats in a barocamp to a conditional altitude of 11 thousand meters above sea level (pressure 190 mm Hg). Tissue metabolite concentrations and enzyme activities were measured using conventional biochemical methods. Results. The results of the study showed that the positive effect of Metovitan, which contained methionine and vitamins E, B1, and B3, on many indicators, including the activity of antioxidant defense enzymes, was significantly higher than the effect of Decamevit, which contained the same components plus vitamins A, B2, B6, B9, B12, vitamin C, and the bioflavonoid rutin. The survival time of rats treated with Metovitan before the experiment was one and a half times longer than that of Decamevit. Conclusion. A preparation containing a limited amount of vitamins acting synergistically on narrow links of cellular metabolism was more effective in preventing oxidative stress than a conventional multivitamin preparation.
