Objective: To investigate the inhibitory effects of 6, 8-ditrifluoromethy-7-acetoychrysin (dFMAChR) on the growth of human liver carcinoma xenograft tumor in nude mice. Methods: The nude mice model was established by inoculation of human liver carcinoma HepG2 cells, and randomly divided into six groups, NS group (0.1 ml/10 g), 5-FU (20 mg/kg) group, ChR (100 mg/kg) group, low dose dFMAChR (20 mg/kg) group, media dose dFMAChR (40 mg/kg) group and high dose dFMAChR (80 mg/kg) group. The body weight and tumor volume and weight were...
