title: [Investigation of the influence of copper and cobalt ions on the carcinogenesis by diethyl-nitrosamine (DENA) in Wistar rats (author's transl)].
abstract: Simultaneous subcutaneous applications of metal salts (CuSO4X 5H2O and CoC12 X 6 H2O respectively) have no influence on the percentage of the tumor yield after long-term subcutaneous applications of diethylnitrosamine (DENA). In accordance with results in syrian golden hamsters a high percentage of tumors of the nasal cavity (predominantly esthesioneuroepitheliomas) occur after subcutaneous injection of DENA into rats, too.
