Abstract

Acetaminophen (N-acety1-p-aminophenol, paracetamol) is widely used as an over-the-counter analgesic and antipyretic drug. Intake of a over dose of acetaminophen may result in severe hepatic necrosis. In this study, we investigated the liver damage in mice using single dose (300 mg/kg) of acetaminophen and the possible protective effects of administration (50-200 mg/kg body weight) of SB-Ex on acetaminophen-induced liver damage in mice. The alanine aminotransferase (ALT), and aspartate aminotransferase (AST) activities were determined in the plasma of mice. The effect of SB-Ex on lipid peroxidation product thiobarbituric reacting substances (TBARS) and some antioxidant enzymes superoxide dismutase (SOD), catalase, d-aminolevulinate dehydratase (-ALA-D) activities, and gluthathione peroxidase (GPx), were also evaluated in the mouse liver homogenate. Acetaminophen caused liver damage as evident by statistically significant increased in plasma activities of AST and ALT. There were general statistically significant losses in the activities of SOD, catalase, -ALA-D, and GPx and an increase in TBARS in the liver of acetaminophen-treated group compared with the control group. However, SB-Ex was able to counteract these effects. These results suggest that SB-Ex can act as hepatoprotectives against acetaminophen toxicity and is a good candidate for further evaluation as an effective chemotherapeutic agent.
