title: Immunologic aspects of 1, 2-dimethylhydrazine-induced colon tumors in rats.
abstract: Investigation of immunologic aspects of colon tumors induced in rats by 1,2-dimethylhydrazine demonstrated that: 1) An antigen in an extract of colon tumors was not detected in the normal colon. It was related to antigens in rat fetuses and did not cross-react immunologically with carcinoembryonic antigen. 2) Mucinous adenocarcinomas of the colon were significantly associated spatially with lymphoid follicles.
