摘要
蝎毒组分Ⅱ（ＳｃｏｒｐｉｏｎＶｅｎｏｍｃｒｕｄｅⅡ，ＳＶＣⅡ）为河南马氏钳蝎粗毒（ＳＶＣ）经分离纯化后获得的有效成分之一。实验结果表明，以丝裂霉素作为阳性对照，ＳＶＣⅡ（４～２０μｇ／ｍｌ）对人直肠腺癌Ｃ１１８４细胞株有明显杀伤作用。与空白对照相比，ＳＶＣⅡ使细胞生长抑制率、细胞毒性和克隆形成抑制率增大（Ｐ＜０．０５或（Ｐ＜０．０１），并存在剂量效应关系，其半数抑制浓度分别为１１．２０μｇ／ｍｌ、１１．９３μｇ／ｍｌ和１７．３８μｇ／ｍｌ。从生长曲线可见，ＳＶＣⅡ对细胞生长呈剂量和时间依赖性抑制。ＳＶＣⅡ还能使细胞分裂指数下降。提示ＳＶＣⅡ具有抗癌细胞增殖作用。
Scorpion Venom Crude Ⅱ(SVC Ⅱ)was one of the effective components which was isolated from the scorpion venom crude extracted from Buthus Martensii Karsch in Henan Province.The experimentalresults showed that SVC Ⅱ with the concentration ranging from 4μg/ml to 20μg/ml had obvious killing acticitv on the human rectum adenocarcinoma C1184 cell line in Vitro in comparison with the positive control which was Mitomycin-c.Compared with the blank control,SVC Ⅱcould induceto increase the inhibitary rate of cell growth,the cvtotoxicitv and inhibited rate of the colonv formation(P<0.05 or P<0.01).There existed the dose-response correlations between the inhibitioneffect and the dose of SVC Ⅱ.The half inhibition concentrations of cell growth(Ⅰ C50)in above experiments were 11.20μg/ml、11.93μg/ml and 17. 38μg/ml,respectively.It was found that SVCⅡ signficantly inhibited C1184 cell growth in the dose-dependent and time-dependent manner in cell growth curve.The mitotic index of C1184 cells could be reduced by SVC Ⅱ.So it was supported that.SVC Ⅱpossess antineoplastic effect on tumor cell proliferation.
