Abstract

This study was aimed to evaluate the preventive role of phytic acid on lysosomal enzymes in isoproterenol (ISO)-induced myocardial infarction (MI) in male Wistar rats. Rats subcutaneously injected with ISO (85 mg/kg) at an interval of 24 h for two days showed a significant increase in the activities of lysosomal enzymes (glucuronidase, N-acetyl glucosaminidase, galactosidase, cathepsin-B and cathepsin-D) were increased significantly in serum and the heart of ISO-induced rats, but the activities of glucuronidase and cathepsin-D were decreased significantly in the lysosomal fraction of the heart. Pretreatment with phytic acid (25 and 50 mg/kg) daily for a period of 56 d positively altered activities of lysosomal hydrolases in ISO-induced rats. Thus, phytic acid possesses a cardioprotective effect in ISO-induced MI in rats.
