摘要: 目的:探讨四氢生物蝶呤(BH4) 对肾缺血再灌注损伤(IR) 模型的作用及其作用机制。方法:复制大鼠肾缺血再灌注模型, 手术前1 h 喂饲BH4, 动态检测其对肾组织NO 含量、cNOS 和iNOS 活性的影响, 并通过肾功能、MPO、MDA 的变化来评价BH4 对肾IR 模型的作用。结果:BH4 能够升高再灌注早期cNOS 活性, 增加内皮源性NO 含量, 减轻炎症反应,减弱再灌注后期对iNOS 的诱导作用。结论:BH4 可改善再灌注初期cNOS 活性, 保护肾功能。

Abstract: AIM: To investigate the effects and mechanisms of tetrahydrobiopterin (BH4) on renal ischemia-reperfusion injury in rats.METHODS: The ischemia-reperfusion model was induced and 20 mg°kg-1 BH4 was orally administrated 1 h before the operation.NO, NOS activity, MPO activity and MDA and renal function were measured in order to assess the efficacy of BH4. RESULTS: BH4 ameliorated cNOS during the early period of reperfusion and increased the NO level in renal tissue which diminish inflammation responses and decrease the induction of iNOS.CONCLUSION: BH4 can attenuate renal ischemia-reperfusion injury, and it may be related to ameliorating cNOS during the early period of reperfusion.
