ABSTRACT
Objective: To observe the lipid-lowering effect of Typha angustifolia extract (TAE) in Sprague Dawley rats. Methods: The rats were randomly divided into six groups, including the hypercholesterolemic diet (HYD) group. Ad libitum food was given to the animals for 60 d to establish dyslipidemia models. The rats were received an ig administration of 1 mL medicine daily. After 120 d the animals were sacrificed by cervical dislocation; Blood was collected to measure total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), nitric oxide (NO), and endothelin (ET) plasma concentration; Livers were collected to measure ApoE mRNA and protein expression; Morphologic changes of aorta ventralis tissue were also observed. Results: Compared with HYD group, TAE had the ability of reducing TC, TG, LDL-C, NO, and ET (P < 0.01), thereby increasing ApoE mRNA and protein expression of the liver (P < 0.01). Conclusion: These results suggested that TAE was capable of effectively decreasing the circulating lipids levels and enhancing the protective effects of artery.
