摘要 目的探讨血小板源生长因子及其受体在系膜增殖中的作用方法将18只雄性SD大鼠随机分为对照组(t组)、肾炎组t组)及布累迪宁(咪唑立宾)组(m组),每组6只、系膜细胞增殖程度用PAS染色方法评估;血小板源生长因子(PDGF—B)及其受体(PDGFR-β)的基因表达由反转录-PCR检测,Westerll blot方法检测其蛋白表达结果与对照组相比,血小板源生长因子-β及其受体的mRNA及蛋白质均明显增加(P〈0.05),系膜细咆数急剧增多(P〈0.05)与肾炎组比较,布累迪宁组血小板源生长因子-β及其受体的mRNA及蛋白量明显减少(P〈0.05),肾小球系膜区的细胞数量明显减少(P〈0.05),结论布累迪宁可阻碍急性肾炎大鼠系膜细胞增殖,其机理可能是通过减少PDGF-β及其受体的表达实现的.
