|Abstract:||To evaluate pretreatment of six polyherbal liquid formulations (PLFs) commercially available in India, on CCl4-induced liver injury, Swiss albino mice were treated for 7 days with distilled water or PLFs (2.6 and 5.2 ml/kg body weight/day, po) followed by single sc injection of 50% (v/v) CCl<sub>4</sub> in arachis oil at a dose of 1ml/kg. The serum biochemical parameters such as alanine transaminases, aspartate transaminases and alkaline phosphatase were estimated. Phenobarbitone-induced sleeping time and liver histopathology were also carried out. CCl<sub>4</sub>-treated animals showed significant increase in the levels of liver enzymes, phenobarbitone-induced sleeping time and revealed fatty changes and centrizonal necrosis on histological examination of liver indicating hepatic damage. When pretreated with PLFs at a dose of 5.2 ml/kg body weight/day, the CCl<sub>4</sub>-induced changes were significantly reversed. The pretreatment with PLFs can prevent acute liver damage induced by CCl<sub>4</sub> only at a higher dose. Therefore, it is suggested that a dose adjustment of these PLFs may be necessary for their optimal effects in human liver diseases.|
