ABSTRACT

Atherosclerosis which results from gradual deposition of lipids in arteries is a leading cause of mortality worldwide. Diet is one of the most important factors underlying atherosclerosis. High-cholesterol diets enhance atherosclerosis and vegetarian diets are known to slow down the process. Artemisia aucheri is a herb of the Composite family. Many species of Artemisia have proven hypolipidemic and antioxidant properties. This study determine the effects of Artemisia aucheri on lipoproteins and atherosclerosis in hypercholesterolemic rabbits. Fifteen male rabbits were randomly divided into three groups. Normal diet group, high-cholesterol diet group [1% cholesterol] and Artemisia aucheri group [1% cholesterol diet supplemented with 100 mg/kg body weight the Artemisi aucheri every other day]. Biochemical factors were measured at the start, end of the first and second months of the study. At the end of the study, the aorta were removed for assessment of atherosclerotic plaques. The results indicate that Artemisia aucheri significantly reduced the level of total cholesterol, LDL cholesterol and triglycerids and increased HDL cholesterol. The degree of atherosclerotic thickness was significantly reduced in the treated group. Therefore, Artemisia aucheri is one of the useful herbal medicine for preventation of atherosclerosis and more studies in this regard is recommended
