河南马氏钳蝎粗毒对体外培养的人食管癌细胞株(Eca109)的毒性

The cytotoxicity of scorpion venom (buthus martensii karshi) on human esophageal cancer cell——Eca109 cultured in vitro

本文应用产于河南的马氏钳蝎(buthus martensii karshi)分泌的粗毒(scorpion venom crude,SVC)处理体外培养的人食管癌细胞株——Eca109,观察了SVC对Eca109细胞的生长抑制及细胞毒性作用。结果显示,SVC可以抑制Eca109细胞的生长,SVC的浓度为0.017μg/ml,处理细胞24、48、72hr后,细胞生长的抑制率达35.6%、39.5%、36.9%;SVC亦可抑制Eca109细胞线粒体脱氢酶的活性,对细胞呈现细胞毒性作用,SVC浓度为0.017μg/ml、0.034μg/ml、0.085μg/ml时,对Eca109细胞的细胞毒性作用分别达63%、56%、59%。SVC对肿瘤细胞的毒性作用及其作用机理值得深入研究。

The cultured human esophageal cancer cell line——Eca109 cells was incubated with the scorpion venom crude (SVC) collected from Buthus Martensii Karshiin Henan Province. The growth inhibition and cytotoxicity of SVC on Eca109 cells were detected. The results showed that Eca109 cell growth was inhibited by SVC. while Eca 109 cells were incubated with SVC for 24, 48, 72hrs. The rates of inhibition were 35.6%, 39.5, 36.9% respectively, the concention of SVC used was 0.017μg/ml. The mitochondrial dehydrogenase of Eca109 cells were also inhibited by SVC, Which had the cytotoxic effect on Eca109 cells. When the concentrations of SVC were 0.017μg/ml, 0.034μg/ml, 0.085μg/ml, the cytotoxicity were 63%, 56% and 59%, respectively. The effect and mechanism of cytotoxicity of SVC on the tumor cells are worth further studies.
