The cardioprotective property of ellagic acid in rats has been reported previously. The present study reveals the protective role of ellagic acid in biochemical parameters including serum iron, plasma iron binding capacity, uric acid, glycoprotein, and electrolytes along with hematological parameters. Rats were subcutaneously injected with isoproterenol (ISO) (100 mg/kg) for 2 days to induce myocardial infarction. ISO-induced rats showed a significant increase in their levels of serum iron, serum uric acid, and blood glucose, and a significant decrease in their levels of plasma iron binding capacity, serum total protein, albumin/globulin ratio, and heart glycogen, when compared with normal control rats. The altered hematological parameters were also observed in ISO-induced rats when compared with normal control rats. Pretreatment with ellagic acid at doses of 7.5 and 15 mg/kg produced significant beneficial effect by returning all the above-mentioned biochemical and hematological parameters to near normal levels.
