The search and development of methods for correction of oxidative stress in conditions of exposure to adverse environmental factors is an actual problem of modern medicine. In experimental conditions the possibility to correct free radical lipid oxidation of rats' cell membranes was studied with the external application of the ointment of herb convolvulus and of the ointment of herb chickweed. The animals were divided into 4 groups and each of them had 20 rats: intact animals which were held in

It was found out that in the blood of experimental animals a daily ultraviolet radiation during three minutes contributes to the increase of lipid hydroperoxides level (by 15-19%), of diene conjugate (by 14-16%), and of malonic dialdehyde (by 40-66%) against the decrease of antioxidant system activity in the blood of intact animals. The introduction of the ointment of herb convolvulus and of the ointment of herb chickweed to rats in the conditions of oxidative stress contributes to the reliable decrease in the blood of lipid hydroperoxides by 9-13%, of diene conjugates by 8-13%, malonic dialdehyde by 15-28% in comparison with the rats of the control group. While analyzing the effect of the ointment on the activity of the components of antioxidant system it was shown that the level of ceruloplasmin in the blood of animals was significantly higher by 13-20%, of vitamin E by 8-14%, of catalase by 13-28% in comparison with the same parameter of the rats of the control group. So, the application of the ointment of herb convolvulus and of the ointment of herb chickweed in the conditions of oxidative stress induced by the influence of ultraviolet rays leads to the stabilization of the processes of peroxidation against the increase of antioxidant system activity.
