Cardioprotective Effect of Nano Gold Kalimag Injection via Inhibiting Oxidative Stress and Improving Myocardial Energy Metabolism in Ischemic Heart Injury Model

Abstract

Many people worldwide die from cardiovascular diseases. Myocardial ischemia can be induced by atherosclerosis, and the main factor responsible for atherosclerosis is the deposition of lipid peroxide in vessels. Therefore, atherogenesis may be prevented and treated at the cellular level by preventing oxidative stress using the properties of nanogold, magnesium and potassium. In this study, we have elucidated the cardioprotective effect of Nano Gold Kalimag injection (NGKM) in the ischemic heart injury model in rats. The ischemic heart injury models were made with adrenaline and pituitrin, and a few myocardial damage-related parameters of the models were observed after NGKM injection. After NGKM injection, the levels of lactate dehydrogenase (LDH), aspartate transamiase (AST), and creatine kinase (CK) in an ischemic heart injury model in rats were detected, and TTC staining and H&E staining were performed. In addition, in the myocardial tissues of rats, superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), catalase, and Na+-K+-ATPase activity were measured, and lactate content and ATP content were measured. NGKM can reduce the infarct area in the ischemic heart injury model and significantly lower LDH, AST, and CK levels. SOD, GSH-Px, and arterial tissue CAT levels significantly increased compared to the model, and MDA contents significantly decreased in myocardial tissue compared to the model group. In addition, myocardial tissue ATP content and Na+-K+-ATPase level in myocardial tissues significantly increased compared to the model group, and lactate content in myocardial tissue significantly decreased compared to the model group. Our findings suggest that NGKM injection has cardioprotective effects by inhibiting oxidative stress in an ischemic heart injury model in rats.
