[The role of bile in the development of colon cancer induced by 1,2-dimethyl hydrazine in rats].
Experimental operative models were created in order to investigate the role of the bile acids in the development of colon cancer in rats. These techniques changed the concentration of bile acids in different parts of the colon, and the daily fecal total bile acid levels. The relationship between these changes and the development of 1,2-dimethylhydrazin-induced colon cancer was studied. Significantly more tumors than in the control group were found if the daily total bile acid level and the concentration of bile acids in the left subsite of the large bowel was increased. Our results suggest that bile acids, as promoting factors, may play a role in the development of colon cancer in rats.
