نبذة مختصرة : Colorectal cancer is one of the leading causes of mortality in the world. The search for new methods of therapy for this disease that could correct the state of oxidative stress during the development of neoplasms is up to date. The aim of this work was to study the level of reduced glutathione and the activity of glutathione-dependent enzymes in the development of 1,2 dimethylhydrazine-induced colon cancer in rats while treated with vincristine and the use of enterosorbent. To induce carcinogenesis, dimethylhydrazine was administered to male rats subcutaneously for 30 weeks at a dose of 7.2 mg/kg of body weight. The rats with induced colon cancer received entorosorbent per os at a dose of 0.2 g per 100 g of body weight daily for 21 days. After detoxification therapy, the rats were administered cytostatic vincristine daily at a dose of 0.23 mg/kg for 14 days. A decrease in the content of reduced glutathione, the activity of glutathione reductase and glutathione peroxidase in the blood and liver tissue of rats with colorectal cancer was established. The use of enterosorbent AUT-M was shown to be effective in stabilizing the indicators of the glutathione system in rats with induced colon cancer. Cytostatic vincristine did not significantly affect the change of the studied indicators, confirming the effectiveness of previous sorption measures.
