title: [Comparative investigations on the organotropic carcinogenic effect of different N-nitroso compounds with rat after single and chronic treatment (author's transl)].
abstract: After the gavage of 200 mg N-nitrosodiethylamine per kg body weight only kidney tumors developed while long-term administration of 10 ppm N-nitrosodiethylamine induced esophageal tumors and hepatocellular carcinomas in female rats (SIV 50). This change of the organ-specific carcinogenic effect is not observed in experiments with N-methyl-N-nitrosobenzylamines substituted with a methyl group at the phenyl moiety. Both chronic treatment and single doses induced tumors of the esophagus and the pharynx.
