ABSTRACT
Aim To study on the protective effects on vein endothelial cell of scallop skite-glycosaminoglycan(SS-GAG)and the mechanism of anti-atherosclerosis action of SS-GAG.Methods The endothelial cell of human umbilical vein had been cultured in vitro, and we established an model of endothelial cell oxidative damage induced by oxidized low density lipoprotein (OX-LDL), MTT assay and chemical methods were used to test the influence of SS-GAG on proliferation activity of endothelial cell oxidative damage and analyze nitric oxide (NO) and endothelial nitric oxide synthase (eNOS).Results Oxidized lowdensity lipoprotein (OX-LDL) remarkably inhibited the ability of cell proliferation, decreased nitric oxide (NO) and endothelial nitric oxide synthase (eNOS) (P
