Research progress on vascular pharmacologic effect of salidroside / 药物评价研究

ABSTRACT

Salidroside antagonizes hypoxia,H2O2,hyper-glucose,homocysteine,smoking,orweightlessness-induced endothelial cell injury,and antagonizes the proliferation of vascular smooth muscle cells and vascular adventitial fibroblasts induced by hypoxia,hyper-glucose,noradrenaline,platelet-derived growth factor,or angiotensin Ⅱ,thus produces vascular protection and improves vascular function.Salidroside plays a dual role of vasoconstriction and vasodilation in regulating resistant blood vessel.The vasodilatory effect of salidroside is endothelium-dependent and endothelium-independent.Salidroside antagonizes vascular contraction and injury induced by KC1,CaC12,noradrenaline,phenylephrine,homocysteine,hyper-glucose,plateau hypoxia,H2O2,and chlorine.Salidroside relieves cerebral vasospasm induced by subarachnoid hemorrhage,and pulmonary hypertension and pulmonary arterial remodeling induced by hypoxia or monocrotaline in rat,attenuates several experimental atherosclerosis,and enhances plaque stability.
