摘要
为了解中药大黄对系膜增殖性肾炎的治疗效果,用计算机图像分析及ELISA法观察了大黄对抗Thy-1肾炎大鼠系膜区细胞外基质的影响,并检测了肾小球培养上清中的白细胞介素-1(IL-1)活性。结果表明,大黄不仅减少了肾炎大鼠基质的堆积,还能降低肾小球培养上清中的纤维连接蛋白(FN)浓度和IL-1活性。肾小球FN浓度在未治疗组非常显著地高于对照组与大黄组(P<0.01),其中大黄组又显著低于对照组(P<0.05)。肾小球IL-1活性未治疗组显著高于大黄组,而大黄组又显著高于正常对照组(P<0.05)。大黄能改善系膜增殖性肾炎大鼠系膜区基质的堆积,其作用可能与其抑制肾小球分泌IL-1有关。
Accumulation of extracellular matrix is a prominent feature of progressive glomerulonephritis (GN). Previously, we have shown that Emodin, an important component of Rhubarb, inhibits the fibronectin (FN) production of cultured mesangial cells. We now provide evidence of the same effect of Rhubarb in immune complex GN induced in rats by injection of anti thymocyte serum (ATS). Rhubarb ameliorated mesangial matrix expansion on day 7 after ATS administration. Decreased FN level and IL 1 activity were found in the supernatant of cultured glomeruli from Rhubarb treated animal at the 7th day. Glomerular tissue FN fluorescence staining was also much weaker than that of the untreated rats. These studies demonstrated that Rhubarb treated anti Thy 1 animal model should develop significantly less matrix expansion. Rhubarb also inhibited synthesis and secretion of fibronectin, an important component of mesangial extracellular matrix. Decreased IL 1 activity might be involved in the therapeutic effect of Rhubarb on mesangioproliferative glomerulonephritis.
