Abstract

The purpose of the present study was to investigate the effect of Korea leek on plasm lipids and platelet aggregation in hypercholesterolemic rats fed different dietary fat. Sprague-Dawley rats were fed with hyperlipidemic diet for 4 weeks in order to induce hyperlipidemia, followed by the feeding of experimental diets for additonal 4 weeks. We used three kinds of lipid(perilla oil, corn oil and lard). Korean leek of experimental diets was prepared by drying and milling. Powdered Cellulose and powdered Korean leek were added to experimental diets at the level of 5% (w/w). Serum concentrations of total lipid, total triglyceride, total cholesterol and LDL-cholesterol decreased in the order of perilla oil, corn oil and lard. Korean leek significantly decreased total lipid, total cholesterol, LDL-cholesterol, platelet count, prothrombin time, and platelet aggregation in rats fed a lard diet. The present observation indicates that Korean leek might be helpful for the prevention and threapy of hyperlipidemia and platelet aggregation.
