Potency of andrographolide as an antitumor compound in BHC-induced liver damage.

CONCLUSIONS

The present investigation relates to the influence of andrographolide, an active compound of Andrographis paniculata Nees. It reverses an experimental liver carcinogenic condition of mice to normal and might be a potential therapeutic/preventive agent for human liver cancer.

OBJECTIVE

A. paniculata (Kalmegh) is extensively used in the Indian traditional system of medicine as a hepatoprotective and hepatostimulative agent and has been reported to have protective effect against different hepatotoxins.

METHODS

Histomorphological, ultrastructural, and biochemical studies were performed for the effect of the andrographolide on control mice, mice treated with hexachlorocyclohexane (BHC) only and BHC + andrographolide. Enzymes for liver function tests were analyzed by spectrophotometric method.

RESULTS

The BHC experimental model forms an irreversible liver tumor in male mice. The histological and ultrastructural changes observed in andrographolide supplementation emphasize the recovery of the damaged liver. This recovery was also reflected in the neoplastic nodule formation. The activity of phosphorylase and glucose-6-phosphatase in the liver of the andrographolide-supplemented group suggests improved glycogenolysis in liver. Serum glutamate pyruvate transaminase, serum glutamate oxalate transaminase, alkaline phosphatase, acid phosphatase, and gamma-glutamyl transpeptidase showed a significant decrease in andrographolide-supplemented animals as compared with BHC-treated animals, suggesting regenerative effects elicited by andrographolide.

CONCLUSIONS

The study indicates that the regenerative capability elicited by andrographolide is possibly due to its ability to reactivate liver function enzymes that catalyze the reaction of several biochemical and synthetic processes and that it may be useful for severe liver damage conditions.
