Effects of Glycosaminoglycan from Scallop Skirt on the Releasing of Vasoactive Substance from Endothelial Cells Injured by Hydrogen Peroxide / 中国药房

ABSTRACT

OBJECTIVE: To observation the effects of Glycosaminoglycan from Scallop Skirt (SS-GAG) on the production of vasoactive substance in the endothelial cells injured by hydrogen peroxide(H2O2). METHODS: In H2O2-induced en-dothelial cell oxidative damage model group which was established with human umbilical vein endothelial cell (HUVEC, ECV304) cultured in vitro, SS-GAG groups (at different concentrations) and the normal group, levels of 6-keto-PGF1a, Thromboxane-B2 and Endothelin (ET) in the culture fluid were detected by radioimmunity assay and the content of nitric oxide was determined by nitrate reductase method. RESULTS: As compared with model group, SS-GAG (at different concentrations) significantly enhanced the levels of 6-keto-PGF1a and NO but significantly decreased levels of TXB2 and ET (P
