Objective:To study the preventive and health effects of Ampelopsis grossedentata on hyperlipidemia. Method:Thirty Wistar rats were divided into three groups:control group, model group and test group. The control group was fed normal diet, while the model and test groups were fed high fat diet.The control and model group were given water while the test group was given water with 20% Ampelopsis grossedentata for 15 w. Serum lipids, hemorrheological indices, myocardial enzymes and IL-6 were measured. Results: At the end of experiment, serum TC, TG, LDL-C, and apoB/apoA, serum and myocardial MDA, myocardial enzymes activities, hemorrheological indices and serum IL-6 were obviously higher in model group while the activities of serum and myocardial SOD and GSH-Px were lower. In test group. serum TC, TG and apoB/apoA levels, serum and myocardial MDA, myocardial enzymes activities, hemorrheological indices, and serum IL-6 were significantly lower than those in model group, but HDL-C, SOD and GSH-Px activities higher. Conclusion:Ampelopsis grossedentata could significantly decrease blood lipids and hemorrheological indices of rats fed with high fat diet, and protect myocardial cells fromoxidation, and as a result to prevent hyperlipidemia and cardiovascular disease.
