商陆皂甙甲治疗大鼠抗-Thy1.1系膜增生性肾炎的实验研究

Therapeutical Effects of Esculentoside A on Rats with MsPGN Induced by Anti-Thy1.1 Antibody

目的 观察商陆皂甙甲 (Es A)对 Wistar大鼠抗 - Thy1.1系膜增生性肾炎模型的治疗效果。方法 制备鼠抗 - Thy1.1系膜增生性肾炎模型 ,随机分为 Es A治疗组、地塞米松 (DXM)治疗组、未治疗组 (模型组 )。另设正常对照组。观察 Es A、DXM治疗 7d后大鼠血清尿素氮、肌酐、2 4 h尿蛋白定量及肾组织病理变化。结果 所有模型大鼠与正常对照组比较 ,尿蛋白定量升高、有核细胞计数增多及系膜区面积扩张均具显著性差异 (P<0 .0 0 1～0 .0 5 ) ;Es A、DXM治疗组与未治疗组比较 ,尿蛋白定量降低、有核细胞计数减少及系膜区面积减小具显著性差异(P<0 .0 0 1～ 0 .0 1)。结论 Es A对大鼠抗 - Thy1.1肾炎有减少尿蛋白排泄、抑制肾小球系膜细胞及系膜基质增生。

Objective To observe the therapeutical effects of esculentoside A (EsA) on rats with mesangial proliferative glomerulonephritis (MsPGN) induced by anti-Thy1.1 antibody and make a comparison of the effects between EsA and dexamethasone(DXM). Methods Wistar rats with MsPGN induced by anti-Thy1.1 serum (ATS) were randomly divided into 3 groups: EsA group, DXM group, and model group. Moreover, a normal group was used for comparison. The BUN, SCr, urinary protein and renal pathological changes were examined after 7 d treatment with EsA and DXM. Results The urinary protein, cell count and mesangium area of glomerulus were significantly higher in all modeled groups than in normal group (P<0.001-0.05), and they were significantly lower in the treated groups than in untreated group (P<0.001-0.01). Conclusion The results suggest that EsA is effective for reducing the urinary protein excretion and inhibiting the proliferation process of glomerular mesangium and matrix in rats with MsPGN.
