CARDIOPROTECTIVE EFFICACY OF TAURINE ON LIPID-METABOLISM OF ISOPROTERENOL-INDUCED MYOCARDIAL INFARCTION
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2016, Vol 8, Issue 12
Abstract
Objective: The present study aimed to evaluate the effect of pre-treatment with taurine on rats in which MI had been induced using isoproterenol (ISO).Methods: Rats were randomly allocated into three groups; the 1st group is the normal control (C) one, the 2nd is the isoproterenol cardiotoxic (ISO) one and the 3rd group is the taurine pretreated (T-ISO) one.Results: The activities of the cardiac biomarker enzymes, AST, LDH, CK and CK-MB were elevated in the ISO-treated group. The membrane-bound  Na+-K+ and Ca2+ ATPase enzyme activities were decreased in the ISO-treated group. The lipid profile either in sera or cardiac tissues was increased in ISO-treated rats except for HDL-cholesterol and phospholipids. The cholesterol ester synthetase (CES) activity was elevated, while lecithin: Cholesterol acyltransferase (LCAT) and lipoprotein lipase (LPL) activities were decreased in the myocardial infarcted rats. In addition, the high level of the troponins I and T was an indication of cardiac necrosis. Pre-treatment with Taurine, however, ameliorated all of these changes, in addition to its effect in improving the oxidation process, as measured by lipid peroxidation and the antioxidant enzymes, superoxide dismutase and peroxidase enzymes. Conclusion: Taurine showed amelioration effects on the changes in lipid profile, oxidative stress and myocardial infarction biomarkers and therefore, can be protected against cardiotoxicity.
