Changes in the indicators of endogenous intoxication in rats with experimental carcinogenesis and the use of enterosorption




endogenous intoxication markers, circulating immune complexes, 1, 2 dimethylhydrazine, enterosorbent AUT


Topicality.Colon cancer is one of the most common malignant tumors. It accounts for 45 % of cases of gastrointestinal cancer in women and 60 % in men. The occurrence of tumors is accompanied by endogenous intoxication syndrome, which requires, in addition to antitumor therapy, the use of accompaniment therapy, in particular, enterosorption.

Aim. To find out changes in endogenous intoxication markers in the body of white rats under conditions of induced 1,2-dimethylhydrazine carcinogenesis and after the application of the AUT enterosorbent.

Material and methods. The experiments were performed on white male rats, which simulated colon cancer by weekly subcutaneous administration of 1,2-dimethylhydrazine at a dose of 7.2 mg/kg body weight for 30 weeks. Enterosorbent AUT was administered intragastrally daily for 21 days after modeling carcinogenesis at a dose of 1 ml of suspension (which corresponds to0.2 g of pure mass of the product) per100 g of animal body weight. The degree of endogenous intoxication was determined by the erythrocyte index of intoxication and the content of molecules of average weight. The state of the humoral immune system was assessed by the content of circulating immune complexes in the serum.

Results and discussion. Under conditions of induced 1,2-dimethylhydrazine carcinogenesis, an increase in the content of all fractions of molecules of average weight was registered. At the same time, an increase in the permeability of erythrocyte membranes was observed, as indicated by an increase in the percentage of erythrocyte intoxication index (the end of the study by 68 %). A statistically significant increase in the content of circulating immune complexes in conditions of chronic neoplastic intoxication was revealed, which reached the highest level in the seventh month of the experiment (335 %). The use of carbon enterosorbent AUT led to the normalization of the studied parameters.

Conclusions. The development of induced chemical carcinogenesis is accompanied by a deepening of the endogenous intoxication of the organism. The use of enterosorbent AUT leads to a decrease in the degree of intoxication, which makes it possible to offer it to be included in the treatment regimen of cancer patients in order to alleviate the course of the disease.
