Abstract Background Hypercholesterolemia is a major risk factor for the development of atherosclerosis and endothelial dysfunction. Methods The present study investigates the possible mechanism of Echinops spinosissimus Turra subsp. spinosus ( E. s. spinosus ) flower on the high cholesterol diet. Results Our in vitro results demonstrated the richness of E.s. spinosus flower in antioxidant compounds, and its antioxidant activities. The co-administration of E.s. spinosus (100 or 200 mg/kg/day) with high-fat diet attenuated hepatotoxicity as monitored by the improvement of oxidative stress biomarkers and plasma lipid and liver parameters, when compared to the hypercholesterolemic mice. Atherogenic index and body weight were also reduced markedly, compared to control mice. These results were confirmed by the improvement of histological changes and DNA damage. Conclusion These data indicate that E.s. spinosus flower reduces the hypercholesterolemia risk and atherogenic properties of dietary cholesterol. Its hypocholesterolemic effect may be due to its antioxidant activities and its richness in bioactive molecule.

Dendrobium Huoshanense

Cardiovascular disease is the highest cause of death, and atherosclerosis (AS) is the primary pathogenesis of many cardiovascular diseases. In this study, we aim to investigate the possible pharmaceutical effects of Dendrobium huoshanense C. Z. Tang et S. J. Cheng polysaccharide (DHP) in AS. We fed zebrafish with high-cholesterol diet (HCD) to establish a zebrafish AS model and treated with DHP and observed plaque formation and neutrophil counts under a fluorescence microscope. Next, a parallel flow chamber was utilized to establish low shear stress- (LSS-) induced endothelial cell (EC) dysfunction model. We observed that DHP significantly improved HCD-induced lipid deposition, oxidative stress, and inflammatory response, mainly showing that DHP significantly increased superoxide dismutase (SOD) activity, decreased plaque formation, and decreased neutrophil recruitment and the levels of total cholesterol (TC), triglyceride (TG), malondialdehyde (MDA), and reactive oxygen species (ROS). Furthermore, DHP significantly improved LSS-induced oxidative stress and EC dysfunction. Our results indicated that DHP can exert treatment effects on AS, which may attribute to its hypolipidemic, antioxidant, anti-inflammatory activities and improving LSS-induced EC dysfunction. DHP has promising potential for further development as a functional natural medicine source targeted at AS prevention.

This descriptive study investigates in a rabbit model of atherosclerosis (i) the extent of atherogenesis induced by cyclosporine A (CsA) or hyperlipidemia alone or in combination and (ii) whether thymoquinone (TQ), a known herbal antioxidant, offers protection against these effects. New Zealand White female rabbits were assigned to five groups of six animals each: Group I, control; Group II, CsA [25 mg kg−1day−1orally (PO)]; Group III, 1% cholesterol; Group IV, 1% cholesterol + CsA (25 mg kg−1day−1PO); and Group V, 1% cholesterol + CsA (25 mg kg−1day−1PO) + TQ (10 mg kg−1day−1PO). Lipids and oxidative stress parameters [Malondialdehyde (MDA) and protein carbonyl] and aortic atherosclerosis were compared. CsA alone did not show a significant effect on either serum lipids and did not induce atherosclerosis. High-cholesterol diet induced atherosclerosis (45 ± 11% of the intimal surface of aorta was covered with atherosclerotic plaques). CsA and high-cholesterol diet increased atherosclerosis severity as measured from intimal and media lesions, but did not affect the extent of atherosclerosis. TQ decreased aortic MDA by 83%. It was also associated with reduced aortic atherosclerosis extend by 52% compared with Group IV. We concluded that (i) CsA aggravates hyperlipidemia-induced atherosclerosis and (ii) TQ attenuates the oxidative stress and atherogenesis induced by the combined effect of CsA and hyperlipidemia.
