Abstract:
:Male Fischer rats were treated at 7 weeks of age with a single oral dose of 1,2-dimethylhydrazine (35 mg/kg). After 1.5 years, the 14 control and 28 treated animals were killed for general autopsy. The incidence of tumor formation in the treated animals was 78.6% as compared to 0% for the control animals. All tumors (1--3/rat) were located in the colon, with the exception of one in the Zymbal's gland of the ear and one in the small intestine. The dosage of 1,2-dimethylhydrazine used in this study is the lowest single oral dose of this carcinogen reported to induce colon tumors.
