[Carcinogenic activity of benzyl-nitrosourea (BzNH) in BD-rats (author's transl)].

Chronic weekly oral and subcutaneous administration of N-Benzyl-N-nitrosourea induced carcinomas of the forestomach and local s.c. sarcomas respectively in BD-rats. This confirms a local carcinogenic effect of the compound. In prenatal experiments in BD-rats no carcinogenic effect of BzNH could be found.
