【摘要】 目的:探讨斑蝥合剂对H22肝癌小鼠的抑瘤作用及其免疫调节的机制。方法:选择移植性肝癌H22小鼠为模型,观察斑蝥合剂的抑瘤作用,检测T淋巴细胞增殖功能、NK细胞杀伤功能、T淋巴细胞表型变化及γ干扰素、白细胞介素-4含量。结果:斑蝥合剂对荷瘤小鼠肿瘤有显著的抑制作用,抑瘤率为65.76%;斑蝥合剂治疗组小鼠T淋巴细胞转化刺激指数和NK细胞杀伤百分数均高于模型对照组(P<0.01);斑蝥合剂治疗组与模型对照组相比,斑蝥合剂治疗更能改变T淋巴细胞亚群比例;斑蝥合剂治疗组小鼠T细胞分泌γ干扰素及白细胞介素-4能力均有升高(P<0.05,P<0.01)。结论:斑蝥合剂具有抑制肿瘤生长的作用,并且对荷瘤小鼠的免疫功能有一定调节作用。其作用机制包括增强小鼠体内T细胞免疫功能、NK细胞的杀伤功能及体液免疫功能。更多还原

【Abstract】 Objective: To investigate the mechanisms of tumor inhibiting and immunoloregulation of Mylabris Mixture on H22 cancer-bearing mice. Methods: H22 cancer-bearing mice were chosen to observe the effects of tumor inhibiting and detect the proliferation function of T lymphocytes, the toxicity function of NK cells, the changes of T lymphocytes and the contents of interferon-γ and interleukin-4. Results: Mylabris Mixture could obviously inhibit the growth of H22 cancer in mice, and the tumor inhibition rat was 65.76%. The stimulation index of T lymphocyte transformation and percentage of NK cells in Mylabris Mixture-treated group were obviously higher than those in the normal control group. The subpopulation proportion of T lymphocytes in Mylabris Mixture-treated group was changed more than the normal control group. The production of interferon-γ and interleukin-4 by T lymphocytes obviously increased in Mylabris Mixture-treated group(P< 0.05, P<0.001). Conclusion:Mylabris Mixture has the effect of inhibiting the growth of tumor constitution, and regulating immunological function on mice with tumor. Its mechanisms include the reinforcement of T lymphocyte immune function, NK cell killing function and humoral immune function.更多还原
