        Liver cancer represents a major health problem with steadily increasing incidence rates. Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third most common cause of cancer-related death. This study was conducted in order to investigate the gross findings following treatment with diethylnitrosamine (DEN) in mice. Sixteen male and female mice (B6C3F1), initially 20 days of age, received intraparietal injection (20 mg/kg three times for a period of two weeks, IP) or were given drinking water (DW) containing 50 ppm DEN; all mice were sacrificed at the 80th week of experiments. Hepatocellular adenoma (HCA) and HCC were induced in B6C3F1), mice by administration of DEN. The numbers of HCA and HCC were 7.4±1.72 (IP) and 7.2±0.86 (DW) in male mice. However, no significant difference was observed between the DW and IP groups. The numbers of HCA and HCC were 0.67±0.33 (IP) and 2.0±0.63 (DW) in female mice. This study showed a tendency for high incidences of liver tumor with long-term exposure of newborn animals by drinking water.
