摘要: 体外培养人脐静脉内皮细胞,乳酸脱氢酶(LDH)试剂盒评价王不留行黄酮苷孵育24 h后的细胞毒性。先给予13.76、6.88、3.44 μmol/L的王不留行黄酮苷和维生素C阳性对照组(浓度为100 μmol/L)预孵育12 h后,再分别以H2O2和高糖诱导内皮细胞损伤。SRB法测定细胞活力,试剂盒检测乳酸脱氢酶(LDH)、丙二醛(MDA)、超氧化物歧化酶(SOD)含量。与模型组相比,王不留行黄酮苷13.76、6.88、3.44 μmol/L组均可改善H2O2和高糖损伤模型的细胞活力,尤以13.76 μmol/L作用最为显著(P<0.01);并且王不留行黄酮苷13.76 μmol/L显著降低H2O2和高糖损伤组培养液中LDH和MDA 释放量,增强细胞内SOD活性。

Abstract: The cytotoxicity of vaccarin on human EA·hy926 endothelial cells was investigated by measuring the release of lactate dehydrogenase (LDH) in extracellular fluid.The model of oxidative injury was induced by hydrogen peroxide (H2O2) and the model of high glucose injury was induced by high glucose after treatment of these cells with different doses (13.76,6.88,3.44 μmol/L) of vaccarin and 100 μmol/L of vitamin C.Then the cell viability was measured by SRB method.The release of LDH,the level of malondialdehyde (MDA) and the activity of superoxide dismutase (SOD) in EA·hy926 were determined according to the manufacturer’s instructions.Hence,the protective effect of vaccarin against H2O2 and high glucose induced endothelial cellular damage was confirmed.As shown,the superior effect of vaccarin was observed at 13.76 μmol/L,which significantly reduced the level of MDA and LDH leakage,and enhanced production of SOD.
