肿节风注射液抗肿瘤及与阿霉素联合用药的实验研究

目的了解肿节风注射液抗肿瘤及与阿霉素联合用药的效果。方法采用四氮唑盐法(MTT法)测定药物的体外抑制作用,用IC50评测直接抗肿瘤效果,用金氏公式进行联合用药分析。结果肿节风注射液能抑制人肝癌细胞Bel7402、人结肠癌细胞HCT-8的增殖,其IC50分别为33.13,52.39mg/mL。3.125,6.25,12.5mg/mL的肿节风注射液与阿霉素联合对HCT-8细胞体外抑制呈相加作用;25,50mg/mL的肿节风注射液与阿霉素联合对HCT-8细胞体外抑制呈协同作用。结论肿节风注射液对Bel7402、HCT-8细胞有一定的抑制肿瘤生长的作用,它与阿霉素联合应用对HCT-8细胞可产生相加或增强的协同抑制效果,尤其是高浓度的肿节风注射液与阿霉素的协同作用更为显著。

Anti - tumor Effect of Zhongjiefeng Injection and Its Combination with Adriamycin

Objective To study the anti-tumor effect of Zhongjiefeng Injection in vitro and its combination with adriamycin.Methods MTT assay was adopted to determine the in-vitro anti-tumor effect,IC50 was used to measure the direct anti-tumor effect,and Jing' s formula was applied to analyze the combination of the drugs.Results Zhongjiefeng Injection can inhibit the proliferation of Bel 7402(human hepatoma cells),HCT-8(human colon cancer cells),and the IC50 was 33.13 mg/mL for Bel 7402 and 52.39 mg/mL for HCT-8 respectively.Zhongjiefeng Injection at the concentrations of 3.125,6.25,12.5 mg/mL showed an efficancy potentiation action with doxorubicin on the inhibition of HCT-8 cells in vitro,and 25,50 mg/mL showed a synergic effect on HCT-8 .Conclusion Zhongjiefeng Injection has a certain in-vitro inhibitory effect on the growth of Bel 7402 and HCT-8,its combination with doxorubicin in vitro can produce synergic effects(a simple combined or enhanced effects)to HCT-8 cells,especially high concentrations of Zhongjiefeng Injection with doxorubicin.It is suggested that Zhongjiefeng Injection in the doubled dosage may have a better synergistic effect with doxorubicin in clinical treatment of colon cancer.
