ABSTRACT
Objective: To evaluate the synergistic protective effect of Momordica charantia and Phyllanthus amarus combination (MC+PA) of doses 200 and 400 mg/kg on the liver in different experimental models of hepatotoxicity. Methods: The hepatoprotective activity was evaluated in ethanol and anti-tubercular drugs (isoniazid-INH, rifampicin-RIF) induced hepatotoxicity models. Hepatotoxicity in both models was induced to all groups except the normal control. Intoxicated rats were treated with silymarin and various doses of MC+PA for 8 d in ethanol-induced and 21 d in INH+RIF induced hepatotoxicity models. At the completion of study, the biochemical markers and the anti-oxidant status (SOD and MDA) were measured and also the histopathological evaluation of the liver tissue was carried out. Results: Combination therapy remarkably reduced the elevated profile of the biochemical markers and thereby improved the anti-oxidant status, thus exhibiting the synergistic hepatoprotective effect when compared with the positive control group (p<0.001). Histopathological evaluation demonstrated that MC+PA decreased the liver damage significantly in comparison with the positive group. Conclusion: The current work suggests that the combined extract showed synergistic effects on ethanol and anti-tubercular drugs induced hepatotoxicity models by significantly decreasing the liver damage.
