RETRACTED: Protective effects of caffeic acid on lactate dehydrogenase isoenzymes, electrocardiogram, adenosine triphosphatases, and hematology on isoproterenol‐induced myocardial infarcted rats

The present study aims to evaluate the protective effects of caffeic acid on isoproterenol‐treated myocardial infarction. Male albino Wistar rats were pretreated with caffeic acid (15 mg/kg) daily for 10 days. After the pretreatment, rats were injected with isoproterenol (100 mg/kg) at an interval o...

Description
Summary:The present study aims to evaluate the protective effects of caffeic acid on isoproterenol‐treated myocardial infarction. Male albino Wistar rats were pretreated with caffeic acid (15 mg/kg) daily for 10 days. After the pretreatment, rats were injected with isoproterenol (100 mg/kg) at an interval of 24 h for 2 days to induce myocardial infarction. Isoproterenol‐treated rats showed increased intensity of lactate dehydrogenase‐1 and 2 isoenzyme bands and elevated ST segments. The activity of the heart sodium potassium adenosine triphosphatase was decreased, and the activities of the heart magnesium adenosine triphosphatase and calcium adenosine triphosphatase were increased in isoproterenol‐treated rats. Isoproterenol‐treated rats also showed a significant increase in the concentration of heart calcium. Furthermore, it significantly increased the counts of red blood cells, hemoglobin, white blood cells, and neutrophils and decreased significantly the concentration of erythrocyte sedimentation rate and the counts of lymphocytes and eosinophils. Pretreatment with caffeic acid showed protective effects on all the biochemical parameters, hematology and minimized alterations in lactate dehydrogenase isoenzymes and electrocardiogram. In vitro study confirmed the free radical scavenging potential of caffeic acid. The observed effects might be due to the free radical scavenging and membrane‐stabilizing property of caffeic acid. © 2010 Wiley Periodicals, Inc.
