Necrosis of the myocardium due to imbalance between coronary blood supply and oxygen demand of the myocardial tissue promotes the evolution of acute myocardial infarction (MI). Onions are considered a rich source of medicinal compounds, of which cycloalliin (CYC), a sulfur containing imino compound with a cyclic structure, has been been extensively reported to exhibit various pharmacological activities. The present study aimed to elucidate the protective effect of cycloalliin in isoproternol (ISO)-induced myocardial infarction in male albino Wistar rats. Results of our investigation showed that treatment with CYC (10 mg/kg) significantly elevated both (+) and (−) left ventricular delta pressure/delta time (LVdP/dt) and decreased left ventricular end diastolic pressure LVEDP compared to the isoproterenol-treated group. The level of TBARS was significantly increased in the ISO-treated group. This was accompanied by diminished myocardial creatine kinase-MB (CK-MB) and lactate dehydrogenase (LDH) activities when compared with the control group (p<0.001). In CYC-treated groups, glutathione (GSH) activity was improved significantly (p<0.05) in comparison to the ISO-treated group. Treatment with CYC showed no sign of alteration in myocardial fibers.
