Anti-Atherosclerotic Potential of Aqueous Extract of Cinnamomum Zeylanicum Bark against Glucocorticoid Induced Atherosclerosis in Wistar Rats

Atherosclerosis is one of the major causes of disability of blood vessels which can result in development of many cardiovascular disorders. There is a strong association between atherosclerosis and insulin resistance and dyslipidemia. To study the anti-atherosclerotic potential of bark extract in insulin resistance associated atherosclerosis and worsened Atherogenic Index (AI) associated with dyslipidemia, which are the predominant complications of steroid diabetes in Wistar rats. A sum of 36 rats were categorized into five study groups and one plain control. In a 12 day study period, respective drug treatments were given every day throughout the study period whereas, dexamethasone dosage was started from day seven onwards. On day 12, fasting blood samples were collected and processed for lipid estimation and the determined values were also used to assess AI further. Animals were sacrificed under ether anaesthesia and the aorta was dissected away for its measurement and histopathological findings. One-way ANOVA was used to analyse the data and multiple comparison was done, interpreted based on Post-Hoc Scheffe test. High dose of dexamethasone (8 mg/kg/i.p) in Dexa Control (DC) group produced significant dyslipidemia, increased risk of atherogenicity (p
