Lipingshu capsule improves atherosclerosis associated with lipid regulation and inflammation inhibition in apolipoprotein E–deficient mice

Abstract

Abstract Background Atherosclerosis (AS) is mainly responsible for cardiovascular diseases. The present study investigated whether Lipingshu capsule (LPS), whose ingredients are present in health food stores, has beneficial effect on AS. Methods C57BL/6 J mice were given a low fat rodent diet and assigned as control group (CON). ApoE−/− mice were placed on high fat rodent diet and randomly separated into high fat diet (HFD) group and HFD + LPS group whose animals were given 0.9 g/kg.BW LPS daily for 10 weeks. Atherosclerotic lesions in aorta and aortic root were evaluated. Serum lipids and multiple cytokine were measured. Results ApoE−/− mice fed with high fat diet had serious aortic lesions, whereas LPS markedly decreased plaque area of the total aorta and of the aortic root. LPS recovered the serum lipid profiles by substantially reducing TC, LDL-C, TG and Ox-LDL contents. Multi-cytokine analysis revealed greater serum levels of IL-1α, IL-1β, IL-6, IFN-γ, GMCSF, RANTES and TNF-α induced by high fat diet slumped with LPS treatment. Conclusion LPS reduces atherosclerotic lesions and thus alleviates AS by lipid profile modulation and inflammation inhibition.
