Results:Administration of hepatotoxins(CCl_4,paracetamol and thiocetamide) showed significant morphological,biochemical and histological deteriorations in the liver of experimental animals. Pretreatment with Hepax had significant protection against hepatic damage by maintaining the morphological parameters(liver weight and liver weight to organ weight ratio) within normal range and normalizing the elevated levels of biochemical parameters(SGPT,SCOT,ALP and total bilirubin),which were evidently showed in histopathological study.Conclusions:The Hepax has highly significant hepatoprotective effect at 100 and 200 mg/kg,p.o.on the liver of all the three experimental animal models.展开更多
