Abstract
The carcinogenic effects of di-n-propylnitrosamine and its two related compounds, beta-hydroxypropyl-n-propylnitrosamine (HPPN) and methyl-n-propylnitrosamine (MPN), were tested in rats and compared. All three substances induced neoplasms in the nasal and paranasal cavities, esophagus, and liver. MPN treatment caused the highest tumor incidence in the esophagus, whereas HPPN induced the most hepatic tumors.
