Objective:To study the mechanism of Ganfujian Granule inhibiting hepatocarcinogenesis in rats.Methods:Ganfujian Granule was adminisˉtered to interfere the hepatocarcinogenesis induced with diethylnitrosamine(DEN)in rats and the expression of cyclinˉdependentˉkinases4(CDK4),cyclinD1,cˉmyc and IGFˉⅡmRNA of hepatocyte was investigated during the period of hepatocarcinogenesis.Results:Ganfujian Granˉule can delay the process and reduce the rate of carcinogenesis,prolong rats'survival time.The expression of CDK4...
