【摘要】 【目的】探讨猪苓汤治疗原发性系膜增殖性肾炎的作用机制。【方法】采用兔抗鼠胸腺细胞抗体(Thy-1)大鼠肾炎模型,检测各组大鼠血液生化指标和细胞因子白细胞介素1β(IL-1β)、肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)的活性以及白细胞介素6信使核糖核酸(IL-6 mRNA)的表达波。【结果】模型组的IL-1β、TNF-α和IL-6水平均升高,IL-6 mRNA表达增强,与正常对照组比较有显著性差异(P<0.01);猪苓汤组能降低IL-1β、TNF-α和IL-6的水平及减弱IL-6mRNA的表达,与模型组比较均有显著性差异(P<0.05或P<0.01)。【结论】加味猪苓汤可能是通过抑制细胞因子的基因表达、降低细胞因子的活性对原发性系膜增殖性肾炎产生治疗作用。更多还原

【Abstract】 [Objective] To explore the therapeutic mechanism of modified Zhuling Decoction (MZD) in treating primary mesangial proliferative glomerulonephritis (PMPG). [Methods] Rat models of PMPG were induced by rabbit type antibody of rat thymocyte (Thy-1). Forty rats were randomized into four groups: A (normal control), B (model), C (treated with heparin) and D (treated with MZD). Biochemical indexes in blood, activities of cytokines such as interleukin-1β (IL-1β), tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6) and mRNA expression of IL-6 were observed. [Results] As compared with group A, serum contents of IL-1β, TNF-α and IL-6 were increased and mRNA expression of IL-6 was promoted in group B (P<0.01 ). MZD could decrease the contents of IL-1β, TNF-α and IL-6 and reduce mRNA expression of IL-6 (P<0.01 or P<0.05 compared with group B). [Conclusion] The therapeutic mechanism of MZD in treating PMPG may be related to the inhibition of gene expression of cytokines and to the decrease of activities of cytokines.更多还原
