СРАВНИТЕЛЬНАЯ ЭФФЕКТИВНОСТЬ ЯНТАРНОЙ КИСЛОТЫ И РЕАМБЕРИНА ПРИ ОКИСЛИТЕЛЬНОМ СТРЕССЕ В ЭКСПЕРИМЕНТЕ

Abstract

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’ organism membranes was studied with the introduction of the succinic acid and of the succinate containing medication called Reamberin (Polysan, St. Petersburg). The animals were divided into 4 groups and each of them had 20 rats: the group with intact animals which were held in standard conditions of vivarium; the control group in which rats were exposed to ultraviolet radiation during three minutes daily; the experimental group in which before ultraviolet radiation animals had a daily intraabdominal intake of the succinic acid in a dose of 100 mg/kg; the experimental group in which before ultraviolet radiation animals had a daily intraabdominal intake of Reamberin in a dose of 100 mg/kg (20 ml/kg). 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 48-53%), of diene conjugate (by 43-48%), and of malonic dialdehyde (by 48-61%) against the decrease of antioxidant system activity in the blood of intact animals. The introduction of the succinic acid to rats contributes to the significant decrease in the blood of lipid hydroperoxides by 15-16%, of diene conjugates by 9-16%, and of malonic dialdehyde by 15% in comparison with the rats of the control group. The introduction of the succinate containing Reamberin to rats in the conditions of oxidative stress contributes to the significant decrease of lipid hydroperoxides in the blood by 27-28%, of diene conjugates by 23-28%, and of malonic dialdehyde by 26-29% in comparison with the rats of the control group. While analyzing the effect of the succinate containing drugs 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 25-32%, of vitamin E by 28-33% in comparison with the rats of the control group. So, the application of the succinate containing antioxidants in the conditions of ultraviolet radiation under experiment leads to the stabilization of the processes of peroxidation against the increase of antioxidant system activity. The intraabdominal introduction in laboratory animals of Reamberin in a dose of 100 mg/kg of succinate prevents the accumulation of lipoperoxidation products and increases the activity of main components of the antioxidant system in rats’ blood plasma, which indirectly exceeds similar effect of succinic acid in a dose of 100 mg/kg in the conditions of oxidative stress.
