Results:Obtained results demonstrated that the cotreatment with FIE significantly prevented the decrease of the body weight and also increased in relative liver weight caused by NDEA. The treatment with FIE significantly reduced the nodule incidence and nodule multiplicity in the rats after NDEA administration.The levels of liver cancer markers such as AST,ALT,ALP,γ-glutamyl transferase,TBL,AFP and carcinoembryonic antigen were substantially increased by NDEA treatment.However,FIE treatment significantly reduced the liver injury and restored the entire liver cancer markers.Histological observations of liver tissues too correlated with the biochemical observations.Conclusions:These finding powerfully supports that F.indica exert chemopreventive effect by suppressing the tumor burden and restoring the activities of hepatic cancer marker enzymes on NDEA and CCl4-induced hepatocarcinogenesis in Wistar rats.展开更多
