【摘要】 目的:探讨温肾活血、益气升清的益筋方对实验性自身免疫性重症肌无力小鼠的治疗机理。方法:用重症肌无力病人的血清被动免疫小鼠,建立实验性自身免疫性重症肌无力模型,针对MG的基本病机是脾肾阳虚兼有血瘀组成益筋方,用益筋方、强的松给小鼠灌胃21天,处死动物。利用流式细胞技术和免疫组织化学方法,分别以T细胞及其亚群为指标,观察益筋方、强的松对EAMG细胞免疫的影响;以IL-2、IL-6、TNF-α为指标,观察益筋方对EAMG细胞因子的影响;通过检测胸腺细胞Bcl-2的表达,观察益筋方对EAMG胸腺的影响。结果:强的松、益筋方均能升高CD3~+,降低CD4~+/CD8~+比值;降低IL-2,降低胸腺Bcl-2表达;对IL-6影响不明显;可升高TNF。结论:益筋方能改善EAMG的肌无力症状,通过影响T细胞和其亚群及细胞因子,调控细胞免疫和体液免疫,起到治疗MG的作用。更多还原

【Abstract】 Objective: the research studied the mechanism of Yi Jin Prescription with function of warming the kidney, promoting blood circulation, supplementing Qi and raising lucid Yang Qi of treating the mice myasthenia gravis(MG) caused by the disease of autoimmunity. Method: C57BL/6 mice were passively transferred by injected intraperitoneally with plasma of myasthenia gravis .According to the MG pathogenesis of deficiency of the kidney and spleen and blood stasis, the Yi Jin Prescription was made. Mice were administered by prednisone and Yi Jin Prescription ,and killed after 3 weeks.By using the flowcytometric analysis and immunohistochemical technique, the effects of the Yi Jin Prescription and prednisone on the T lymphocyte and T lymphocyte subgroups of the EAMG of mice were observed respectively. The effect of Yi Jin Prescription and prednisone on the EAMG lymphocyte factors was observed by examining the index of TL-2,TL-6 AND TNF-α.The effect of Yi Jin Prescription and prednisone on the thymus was investigated by examining the expression of Bcl-2 of thymus cells. Results: the ratio of CD3~+was higher than the control group and the model group obviously; the ratio of CD4~+ and CD8+were lower significantly than the control group and the model group; the ratio CD4/CD8 was decreased significantly than the control group and the model group. the level of IL-2 was lower than the control group and the model group obviously. the level of IL-6 has no obvious difference with control group; the level of TNF was higher than control group and model group ;the expression of Bcl-2 was lower than the control group and the model group. Conclusions: Yi Jin Prescription can improve the lack strength of muscles and regulate the T lymphocyte and antibody immunological function through impacting on the T lymphocyte and T lymphocyte subgroup and cell factor to treat MG.更多还原
