The aim of the present study was to evaluate the effect of tramadol on isolated rat hearts subjected to global ischemia-reperfusion injury.
Langerdorff perfused isolated rat hearts were subjected to 60 min of global ischemia following 60 min of reperfusion. In group I and III hearts were received tramadol before the onset of ischemia. Following the ischemic period, group II and III hearts were received tramadol infusion. Group I and IV hearts were subjected to saline at the same time point. The myocardial postischemic recovery was compared using hemodynamic, coronary flow, biochemical parameters from coronary effluent, and oxidative stress markers from heart tissue homogenates.
There were significant differences between tramadol and saline used groups in hemodynamic parameters. GPx values of groups I and III were significantly lower than group IV (p<0.05). SOD values of groups I, II and III were higher than group IV (p<0.05). LDH values of groups I and II were significantly lower than groups III and IV (p<0.05).
Tramadol provides a cardioprotective effect against myocardial ischemia-reperfusion in isolated rat heart.
本研究旨在评估曲马多对遭受全心缺血-再灌注损伤的离体大鼠心脏的影响。
采用Langendorff灌注离体大鼠心脏,先灌注60分钟,然后进行60分钟全心缺血,再灌注60分钟。在I组和III组中,心脏在缺血开始前接受曲马多。缺血期后,II组和III组心脏接受曲马多输注。I组和IV组心脏在相同时间点接受生理盐水。使用血流动力学、冠状动脉流量、冠状动脉流出液的生化参数以及心脏组织匀浆的氧化应激标志物比较心肌缺血后恢复情况。
曲马多组和生理盐水组在血流动力学参数方面存在显著差异。I组和III组的谷胱甘肽过氧化物酶(GPx)值显著低于IV组(p<0.05)。I组、II组和III组的超氧化物歧化酶(SOD)值高于IV组(p<0.05)。I组和II组的乳酸脱氢酶(LDH)值显著低于III组和IV组(p<0.05)。
曲马多对离体大鼠心脏的心肌缺血-再灌注具有心脏保护作用。
