Two subcutaneous injections of N-bis(2-hydroxypropyl)nitrosamine (BHPN) to mice on day 1 and 8 induced tumors of the lung, liver, nasopharynx and pancreas, when animals were killed at the end of one year. The tumor incidences of lung were 90-100%; those of liver 60-92%; those of nasopharynx 3-13%; those of pancreas 2-3%, respectively. The average tumor nodules of lung and those of liver increased in a dose-dependent manner. Two doses of 50 mg/g body weight of BHPN induced one duct cell carcinoma and one acinar cell adenoma of pancreas in a mouse, respectively.
