ABSTRACT
Objective Utilizing the characters of pyrrolidine dithiocarbamate known as a specific inhibitor of NF‐κB and imidapril known as a specific inhibitor of angiotensin converting enzyme ,this study was to initially investigate the relationship between NF‐κBp65 and AngⅡ during the process of myocardial ischemia reperfusion injury .Methods Rat models of myocardial ischemia reper‐fusion injury were successfully established .The observation point is 60 min of reperfusion after 30 min(I30 min R60 min ) ischemia ,the DNA activate of NF‐κBp65 was detected by ELISA ;the content of AngⅡ in blood plasma and cardiac were determined by radioim‐munoassay .We pretreated with pyrrolidine dithiocarbamate ,imidapril ,and both of them to observe changes of the same indexs .Re‐sults Compared with I30 min R60 min ,Pyrrolidine dithiocarbamate ,Imidapril and pyrrolidine dithiocarbamate add imidapril could all ob‐viously inhibit NF‐κBp65 activation and depress the content of Ang Ⅱ in blood plasm and cardiac ,the pyrrolidine dithiocarbamate add imidapril was most obviously .Conclusion During the process of myocardial ischemia‐reperfusion injury ,NF‐κBp65 had been activated ,and the content of Ang Ⅱ in blood plasm and cardiac had increased .NF‐κBp65 and AngⅡ could influence and promote each other during myocardial ischemia reperfusion injury .
