摘要: 目的 探讨建立山羊心肌缺血预适应(IPC)实验模型的方法及其影响因素。方法 将12只雄性山羊,麻醉、气管插管接呼吸机后均由右侧开胸,升主动脉插主动脉供血管,上下腔静脉插腔静脉引流管,建立体外循环(CPB),阻断升主动脉(ACC)5min,开放恢复灌注5min,共行3轮IPC实验,随后ACC 60min,心脏停搏,后开放升主动脉心脏再灌注90min。CPB前及再灌注后30、60、90min监测血流动力学及心功能。结果 12只山羊中9只顺利脱离CPB机,停机后血流动力学逐渐稳定;一只麻醉时死亡,一只心脏复跳后反复出现室颤,经多次除颤无效死亡;一只术后出现急性肺水肿死亡。平均转机时间126±14min,平均预充胶体(6%贺斯代血浆或血)量650±1 50ml,平均追加胶体量165±50ml。再灌注后与CPB前比较,血流动力学及心功能恢复满意。结论 正确的实验方法可模拟临床顺利完成山羊的IPC实验,把握好几个关键的技术,可有效的提高山羊IPC实验模型的成功率。

Abstract: To establish Chronic Renal Failure (CRF) with high-grade proteinuria rat model. Methods: The 5/6 nephrectomy rat was replicated and fed with high-protein diet. Results: Volume of Scr and 24h proteinuria in CRF rat’s with 40% high-protein diet group were increased significantly than those of normal diet control and 20% high-protein diet group. Renal pathology showed more severely neprosclerosis and matrix fibrosis in 40% high-protein diet group than other groups. Conclusion: CRF with high-grade proteinuria rat models can be established by supplying high-protein diet to replicated 5/6 nephrectomy rats.
