title: Carcinogenicity of di(N-nitroso)-perhydropyrimidine (DNPP) after intraperitoneal application to rats.
abstract: Male Sprague-Dawley rats received 30 mg/kg body wt. (group I) or 15 mg/kg (group II) di(N-nitroso)-perhydropyrimidine (DNPP) by the intraperitoneal route once a week for life. The DNPP treatment significantly reduced the life expectancy in both groups. DNPP induced tumors of the esophagus (27% incidence in group I, 33% in group II) and possibly also of the liver (4% incidence in group I, 8% in group II).
