Tóm tắt

AbstractThe present study was aimed to evaluate the protective effects of N‐acetyl cysteine (NAC) on changes in the activities/levels of adenosine triphosphatases and minerals in isoproterenol‐induced myocardial‐infarcted rats. Male albino Wistar rats were pretreated with NAC (10 mg/kg body weight) daily for a period of 14 days. After pretreatment period, rats were induced myocardial infarction (MI) by isoproterenol (100 mg/kg body weight). The activity of sodium/potassium‐dependent adenosine triphosphatase was decreased, and the activities of calcium‐ and magnesium‐dependent adenosine triphosphatases were increased in the heart of isoproterenol‐induced myocardial‐infarcted rats. Furthermore, the levels of potassium were lowered and the levels of sodium and calcium were increased in the heart of isoproterenol‐induced rats. Increased plasma lipid peroxidation was observed in isoproterenol‐induced rats. Pretreatment with NAC showed protective effects on adenosine triphosphatases, minerals, and lipid peroxidation. The in vitro study confirmed the reducing property of NAC. The observed effects are due to the membrane‐stabilizing and antioxidant effects of NAC. The results of this study will be useful for the prevention of MI. © 2012 Wiley Periodicals, Inc. J Biochem Mol Toxicol 26:276–281, 2012; View this article online at wileyonlinelibrary.com.
