摘要 目的研究外源性抑炎因子生长激素释放多肽-2(GHRP-2)对脓毒性急性肾损伤(AKI)的干预作用。方法选取SD大鼠80只,以牛磺胆酸钠胰胆管注射法建立重症急性胰腺炎(SAP)大鼠为脓毒症模型,将大鼠随机分为2组各40只,分别为对照组和干预组。对照组腹腔内注射生理盐水,干预组腹腔内注射GHRP-2。观察两组大鼠血清肌酐(Cr)、尿素氮(BUN)以及肾组织丙二醛(MDA)和超氧化物歧化酶(SOD)水平变化。结果给药后0 h两组大鼠血清Cr、BUN水平及肾组织MDA、SOD水平差异均无统计学意义(P>0.05);给药后6、12及24 h干预组大鼠血清Cr、BUN水平明显低于对照组(P<0.05),肾组织MDA水平低于对照组(P<0.05),肾组织SOD水平高于对照组(P<0.05)。结论 GHRP-2对脓毒性AKI大鼠可降低血清Cr、BUN水平,增强肾组织SOD活性,降低肾组织MDA水平,对肾脏具有保护作用。
