Carcinogenicity

The potential carcinogenicity of 2-amino-5-nitrophenol was tested by NTP by oral administration (gavage) in corn oil to F344/N rats (100 and 200 mg/kg) and B6C3F1 mice (400 and 800 mg/kg) for 2 years. There was some evidence of carcinogenic activity in low-dose male rats, as indicated by increased incidence of acinar cell adenomas of the pancreas. No evidence of carcinogenic activity was found among female rats and the low-dose groups of male and female mice. The poor survival rates in the high-dose male rats and high-dose male and female mice reduced the sensitivity for detecting potential carcinogenic response.

läuterung methode
