Lack of tumorigenic activity of 1,1-dimethylhydrazine in Syrian golden hamsters treated by subcutaneous injection.

Abstract

Syrian golden hamsters were treated throughout their lifespan by weekly subcutaneous injections of 1,1-dimethylhydrazine (1,1-DMH) at doses of 0, 8, 17 and 35 mg/kg body weight. In contrast to our previous study using European hamsters, no treatment-related tumors occurred in this study.
