Effect of propolis extract on acute carbon tetrachloride induced hepatotoxicity

Abstract

Ethanolic extract of propolis was administered to rats intoxicated by carbon tetrachloride. Administration of bolus dose of CCl₄ (1.5 ml/kg, ip) resulted in elevation of serum transaminases and serum alkaline phosphatase activities. Levels of hepatic lipid peroxidation were significantly increased. On the contrary, there was significant decrease in hepatic reduced glutathione level. The propolis extract (100 and 200 mg/kg, po) exhibited recoupment in both pre- and post-treatment (prophylactic and curative studies) of biochemical changes induced by CCl₄. The post treatment of 200 mg/kg, po extract

showed most significant hepatoprotective effect. Histopathological studies showed damage in hepatocytes and disturbed chord arrangement after toxicant administration. Propolis extract (200 mg/kg, po) was found to be more effective in restoring CCl₄ induced histopathological alterations.
