title: Carcinogenesis of nitrosomethylundecylamine in Fischer rats.
abstract: Nitrosomethylundecylamine was synthesized and administered to Fischer rats by gavage in olive oil solution, at a dose of 46 mg/animal/week for 30 weeks. There were high incidences of hepatocellular carcinomas and cholangiocarcinomas in the liver and of squamous cell carcinomas and alveolar cell adenocarcinomas in the lung. In contrast with the activity of the next higher homolog, nitrosomethyldodecylamine, no bladder tumors were induced.
