摘　　要：目的探讨吗替麦考酚酯(MMF)对SD大鼠抗肾小球基底膜(GBM)肾炎模型的治疗作用。方法将实验动物分为空白对照组、模型对照组和MMF治疗组,利用兔抗SD大鼠GBM抗体血清制备SD大鼠抗GBM肾炎模型。检测各组动物在给药后第0、1、2、3和4周的24h尿蛋白、血肌酐和尿素氮等生化指标;采用酶联免疫吸附法检测在给药后第0、4周各组动物外周血中IL-1、TGF-β1的水平;HE染色和碘酸雪夫氏(PAS)染色分析各组动物肾脏组织病理形态学变化。结果 MMF治疗1周后,24h尿蛋白的排泄量开始下降;MMF治疗4周后,相较于同期的模型对照组,MMF治疗组SD大鼠的24h尿蛋白的排泄量显著性下降,外周血尿素氮、血肌酐以及与免疫相关的细胞因子IL-1和TGF-β1的水平也远远低于模型对照组(P<0.05)。HE和PAS染色结果表明,MMF治疗组大鼠的肾小球及其周围间质区炎性细胞浸润较模型对照组减少,新月体数量明显下降。结论 MMF可提高抗GBM肾炎SD大鼠的肾功能,抑制IL-1和TGF-β1的产生,阻止模型大鼠的肾脏病变。Objective To investigate the influence of mycophenolate mofetil（MMF） on blood and urine biochemical indica‐tors as well as the expressions of IL‐1 in anti‐glomerular basement membrane（GBM ） nephritis SD rats .Methods The SD rats were randomly divided into control group ,model group and MMF group .And then the models of SD rat anti‐GBM nephritis were estab‐lished by injecting rabbit anti‐SD rat GBM serum antibodies .The urinary protein and blood parameters were detected initially ,1st , 2nd ,3rd and 4th weeks after administration respectively .The expressions of IL‐1 and TGF‐β1 were detected by Elisa Kit and the re‐nal pathological changes were observed by HE and PAS staining .Results After treatment for 4 weeks by MMF ,the 24 h UP ,BUN and SCr levels were lower in MMF group than those of the model group（P〈0 .05） .And the expressions of IL‐1 and TGF‐β1 were decreased in MMF group .The results of HE and PAS staining showed that in model group rats ,glomerular tuft morphology was destroyed and inflammatory cell infiltration was observed in the glomeruli .Some glomeruli had cellular crescent formation .Infiltra‐tion of inflammatory cells was also observed in the interstitium .MMF clearly improved these pathological changes overall ,with im‐provements noted in both glomerular and tubular degeneration as well as in the infiltration of inflammatory cells .Conclusion MMF shows certain renal protective effect on anti‐GBM nephritis SD rats .
