摘要 目的:观察大鼠肾脏缺血再灌注(IRI)的不同时间组炎性细胞因子白细胞介素-6(IL-6)在肾组织和血液中的含量变化及姜黄素预处理的影响。方法:采用大鼠肾缺血再灌注(IR)模型(将大鼠右肾切除,夹闭左肾蒂,60min后松开使左肾再灌注),用双抗体夹心ELISA法动态检测肾组织和血液中IL-6含量,以及用生化分析仪测定BUN、Scr等指标变化。取肾脏称重,计算肾系数:肾重/体重,同时观察肾脏病理学变化。结果:肾组织中IL-6含量在单纯缺血组、R4h和R24h组均明显低于对照组(P<0.05),而R1h组与对照组水平差异无统计学意义,但与缺血组比较,其增高差异有统计学意义(P<0.01)。血清IL-6水平在R1h组明显高于单纯缺血组(P<0.01)。姜黄素干预可使R4h和R24h组的IL-6含量较未处理组增高(P<0.01),同时使R4h组BUN、Scr及肾系数也明显增高(P<0.01或P<0.05),使R24h组的Scr明显降低(P<0.01),但BUN及肾系数无明显变化。结论:在再灌注的早期,肾组织和血液中IL-6的含量升高,随后下降接近于单纯缺血水平。姜黄素预处置使IL-6增多的同时加重早期肾缺血再灌注损伤(IRI),姜黄素早期使肾功能障碍加重的作用是否与IL-6增加有关,值得进一步探讨;随着再灌注时间延长,姜黄素治疗作用逐渐显示。姜黄素与IL-6之间具体的作用机制有待进一步研究。
