ABSTRACT
Background. Every year the number of cases of colorectal cancer increases. Chemotherapy is one of the main methods of treating cancer. However, chemotherapeutic treatment of colorectal cancer is inextricably linked to hepatotoxic reactions.
Objective. The aim of this study was to investigate the effect of the cytostatic vincristine on the background of previous enterosorption correction with the drug aut-m in adenocarcinoma of the colon.
Material and methods. To simulate carcinogenesis, dimethylhydrazine (DMH) was administered subcutaneously to 77 rats for 30 weeks at a dose of 7.2 mg/kg body weight. After simulation of colon cancer, the animals were intragastricly administered entorosorbent at a dose of 1 ml of suspension (corresponding to 0.2 g of net weight of the drug) per 100 g of body weight of the animal, daily for 21 days. After detoxification therapy, rats with simulated carcinogenesis were administered the daily cytostatic vincristine at a dose of 0.23 mg/kg for 14 days.
Results. It was found that prolonged administration of dimethylhydrazine is accompanied by destructive changes in plasma membranes, as evidenced by increased activity of enzymes alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and serum urea.
Conclusions. The used sorbent aut-m showed an effective effect on reducing the manifestations of cytolytic processes in induced carcinogenesis, as indicated by the normalization of the studied parameters. The cytostatic vincristine, which was used in rats with induced colorectal cancer after enterosorption therapy, did not significantly affect the enhancement of cytolytic processes, which confirms the effectiveness of previous sorption measures under these conditions.
