目的:探讨鸟氨酸脱羧酶(ODC)/多胺(PAs)通路在运动恢复老龄心肌对缺血预适应(IPC)刺激敏感性中的作用。方法:采用3月龄、18月龄及梯度运动6周18月龄大鼠,离体心脏灌流方法复制心肌缺血/再灌注(IR)与IPC模型。HPLC测定心
Objective: To investigate the role of ornithine decarboxylase (ODC) / polyamine (PAs) pathway in the recovery of senile myocardial ischemia-reperfusion injury (IPC) induced by exercise. Methods: Myocardial ischemia / reperfusion (IR) and IPC model were induced by 3-month, 18-month and gradient 6-week-old 18-month-old rats. HPLC determination of the heart
