目的:探讨核因子KB(NF-κB)抑制剂吡咯烷二硫代氨基甲酸盐(PDTC)对大鼠急性坏死性胰腺炎(ANP)的预防治疗作用。方法:大鼠80只随机分为正常对照组(Z)、胰腺炎组(Y)和干预纽.干预组又分为建模前1h PDTC干预组(A)、建模后1h PDTC干预组(B)...目的:探讨核因子KB(NF-κB)抑制剂吡咯烷二硫代氨基甲酸盐(PDTC)对大鼠急性坏死性胰腺炎(ANP)的预防治疗作用。方法:大鼠80只随机分为正常对照组(Z)、胰腺炎组(Y)和干预纽.干预组又分为建模前1h PDTC干预组(A)、建模后1h PDTC干预组(B)和建模后6h干预组(C).干预组按不同时间ip PDTC.建模后6,12,24 h分批处死,临床全自动生化仪检测血清谷丙转氨酶(ALT)和淀粉酶(AMY),用凝胶迁移率改变分析法(EMSA)测定胰腺和肝脏中NF-κB的活性.同时观察胰腺和肝脏的病理改变.结果:正常大鼠组织中几乎测不到NF-κB的活性,与Z组比较,Y组胰腺和肝脏组织中6,12,24 h NF-κB活性分别明显增加(P<0.001).建模前1h,1h后使用PDTC,胰腺和肝脏组织中NF-κB活性均受到抑制(18.14±3.30,23.79±3.62 vs 24.82±4.57:10.68±2.51,13.83±2.70 vs 16.38±2.50;P<0.05),Y组血清ALT,AMY均高于对照组.病理学检查可以见到Y组和A,B,C组的胰腺和肝脏均有炎性改变,但A组较Y组明显为轻.结论:NF-κB的异常活化与SAP以及肝损伤有明显关系:PDTC对SAP时肝损伤的发生有一定的预防作用.展开更多
