TINCTURE OF MEDICINAL PLANTS AND OXIDATIVE STRESS IN THE CONDITIONS OF COLD EXPOSURE

Abstract

The increase of adaptation capabilities of a person to the damaging effect of cold with the help of pharmacological medicine is important at prophylaxis of different diseases and pathologies development. In experimental conditions the possibility to correct free radical lipid oxidation of rats’ organism membranes was studied with the oral introduction of the tincture made of birch, nettle and plantain leaves. The animals were divided into three groups and each of them had 15 rats: intact animals which were held in standard conditions of vivarium; the control group in which rats were exposed to cold during three hours daily; and the experimental group in which before cooling animals had a daily oral intake of the tincture made of birch, nettle and plantain leaves in a dose of 5 ml/kg. It was found out that in the blood of experimental animals a daily cold exposure during three hours contributes to the increase of lipid hydroperoxides level (by 20%), of diene conjugate (by 29%), and of malonic dialdehyde (by 21.5%) against the decrease of antioxidant system activity in the blood of intact animals. The introduction of the tincture to rats in the conditions of cold exposure contributes to the reliable decrease in the blood of lipid hydroperoxides by 19%, of diene conjugates by 13%, of malonic dialdehyde by 18% in comparison with the rats of the control group. While analyzing the effect of the tincture on the activity of the components of antioxidant system it was shown that the level of ceruloplasmin in the blood of animals was reliably higher by 22%, of vitamin E by 19%, of catalase by 18% in comparison with the same parameters of the rats of the control group. So, the application of the mentioned tincture in the conditions of long cold exposure of the organism of experimental animals leads to the stabilization of the processes of peroxidation against the increase of antioxidant system activity.
