According to WHO, mortality from malignant neoplasms ranks second in the world after cardiovascular disease. At the same time, the incidence is increasing in all countries, especially in industrial regions and large cities. One of the symptoms of the severe course of the disease is the activation of free radical oxidation processes in the body, which leads to the search for new effective methods that can be offered to the general schemes of treatment of cancer patients.</p><p><strong>The aim of the study</strong> – to investigate the activity of lipid peroxidation and the oxidative modification of proteins under conditions of dimethylhydrazine hydrochloride-induced colon cancer after applying resveratrol.</p><p><strong>Research </strong><strong>M</strong><strong>ethods.</strong> The experiments were performed on white male rats, which were simulated colon cancer by weekly subcutaneous administration of 1,2-dimethylhydrazine at a dose of 7.2 mg / kg body weight for 30 weeks. Antioxidant resveratrol was administered intragastric at a dose of 20 mg / kg daily for 7 months. The activity of free radical processes was assessed by the content of TBA-active products, nitrite ion and 2,4-dinitrophenyl hydrazones in the serum and liver of experimental rats.</p><p><strong>Results and </strong><strong>D</strong><strong>iscussion.</strong> After the administration of 1,2-dimethylhydrazine to the animals, an increase in the content of TBA-active products, 2,4-dinitrophenyl hydrazones of neutral and basic nature, as well as nitrite ion was observed during the whole study period. Against the background of daily use of resveratrol, the results were twice or even three times lower than in the group of animals that were administered 1,2-dimethylhydrazine.</p><p><strong>Conclusion</strong><strong>s</strong><strong>.</strong> The results obtained confirm the antioxidant properties of resveratrol, which are indicated by a decrease in the content of TBA-active products and 2,4-dinitrophenyl hydrazones under conditions of induced colon cancer.</p> ER -
