Experimentally Induced Hyperlipidemia and Associated Atherosclerosis in the Aorta and Vascular Expression of CD 31, CD44, Beta-catenin and E Cadherin in Wistar Male Rats

Abstract

Background: Hyperlipidemia is the disorder of lipid metabolism, characterized by elevated serum total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and very low-density lipoproteins cholesterol (VLDL-C) and decreased high-density lipoprotein cholesterol (HDL-C). Atherosclerosis is a cardiovascular and fibroproliferative inflammatory disease commonly associated with dyslipidemia.Methods: The study was conducted using 24 Wistar male rats, divided into two groups of 12 rats each. Hyperlipidemia and atherosclerosis were induced by the addition of 1% cholesterol and 15% saturated oil to the 1000g of standard rat diet and given to group II rats. Group I kept as control and maintained for 90 days. Result: The present experiment established hyperlipidemia with a significant increase of TC, TG, LDL-C and decreased HDL-C cholesterol with initiated atherosclerotic lesions in the aorta and showed varying degrees of positivity with CD31, CD44, Cadherin and Beta-catenin proteins.
