We examined the protective effects of Ginkgo biloba extract (EGb761) postconditioning on myocardial ischemia reperfusion injury in rabbits. Four groups of 8 white rabbits were allocated to: pseudo surgery group: the left coronary was lined without blocking for 160 min after thoracotomy; ischemia and reperfusion group (IR): the left anterior descending coronary artery was blocked for 40 min and ...
BACKGROUND The aim of this study was to investigate the effects of remote ischemic conditioning on ischemia-reperfusion injury in rat muscle flaps histopathologically and biochemically. METHODS Thirty albino rats were divided into 5 groups. No procedure was performed in the rats in group 1, and only blood samples were taken. A gracilis muscle flap was elevated in all the other groups. Microcl...
Postconditioning, i.e., brief intermittent episodes of myocardial ischemia-reperfusion performed at the onset of reperfusion, reduces infarct size after prolonged ischemia. Our goal was to determine whether postconditioning is protective against myocardial stunning. Accordingly, conscious chronically instrumented dogs (sonomicrometry, coronary balloon occluder) were subjected to a control seque...
Edaravone, an effective free radical scavenger, can alleviate myocardial ischemia-reperfusion injury (IRI) by decreasing reactive oxygen species (ROS) accumulation. The speckle tracking imaging (STI) could precisely and objectively evaluate the global and regional myocardial deformation. The aim of our study was to assess the protective effect of edaravone postconditioning on IRI in rabbits by ...
Mitochondria play a pivotal role in cardioprotection. Here we report some fundamental studies which considered the role of mitochondrial components (connexin 43, mitochondrial KATP channels and mitochondrial permeability transition pore) in postconditioning cardioprotection. We briefly discuss the role of mitochondria, reactive oxygen species and gaseous molecules in postconditioning. Also the ...
Stroke is the second leading cause of death and the primary cause of disability in humans. The phenomenon of ischemic tolerance perfectly describes the quote: “What does not kill you makes you stronger.’’ Ischemic preor postconditioning is actually the strongest known procedure to prevent or reverse delayed neuronal death. It works specifically in sensitive vulnerable neuronal populations, whic...
