Protective effect of neferine against isoproterenol-induced cardiac toxicity.

| Abstract |
The present study was designed to investigate the cardioprotective effect of neferine against isoproterenol-induced myocardial infarction. Neferine was given orally for 30 days, and isoproterenol was injected subcutaneously for 2 days. Histopathological examination of heart tissue of isoproterenol-treated rats showed myocardial necrosis. Biochemical analysis of isoproterenol-treated rats showed significant increase in the serum marker enzymes--creatine kinase, lactate dehydrogenase, and aspartate transaminase and increased serum glycoprotein components with a concomitant decrease in the heart tissue homogenate when compared to control. Increased lipid peroxidation and decreased antioxidants reduced glutathione, superoxide dismutase, catalase, glutathione-S-transferase, glutathione peroxidase and altered lipid profile in serum and tissue was also recorded in the isoproterenol-treated rats, whereas the rats which received neferine pre-treatment followed by isoproterenol injection showed minimal histological changes, absence of inflammation, and a significant decrease in the serum marker enzymes and serum glycoprotein components with a concomitant increase in the heart tissue homogenate when compared to isoproterenol group. Neferine pre-treatment restored the altered biochemical parameters and lipid profile to near normal. The results of the present study showed that neferine exerts strong antioxidant property against isoproterenol-induced oxidative stress and can be used as a potent cardioprotective agent against isoproterenol-induced myocardial infarction.
