<div><p><strong>Objective: </strong>Discussion the role of edaravone as a free radical scavenger in protective effect of thrombolysis in acute myocardial ischemia reperfusion injury. Besides compared with the control group and analyze the possible mechanism which is widely used in clinical setting. <strong>Method: </strong>80 patients hospitalized within year 2012−2013 with acute myocardial infarction (AMI) were treated with intravenous thrombolytic therapy, and were divided into treatment group (n = 41) and control group (n = 39). Edaravone injection 30 mg + 0.9% normal saline solution 100 mL with intravenous drip, BID for 14 days was given to the treatment group before and after thrombolytic treatment. Whereas, control group was treated with intravenous drip of placebo. Both groups were monitored by echocardiography and hemodynamic monitoring, and the myocardium was measured by echocardiography. Coronary artery CT was used to determine the degree of obstruction. <strong>Results: </strong>Compared with the control group, pain and reperfusion arrhythmia in treatment group was reduced. The area of myocardial wall movement disorder was significantly decreased (<em>p</em> &lt; 0.05), the difference was statistically significant. CT result comparing treatment group and control group and show that rate of coronary recanalization increases 1.7 times (<em>p </em>&lt; 0.01), the differences were statistically significant. <strong>Conclusion: </strong>For acute myocardial ischemia injection of edaravone before reperfusion and combine with pharmacological treatment can alleviate myocardial ischemia reperfusion injury, effectively scavenge oxygen free radicals and improve the ability of antioxidant. Both improve the thrombolytic treatment and protective effect for acute myocardial ischemia were significant. Hence, edaravone can is a kind of new milestone in the clinical cardiovascular drugs.</p></div>

Background. Global myocardial ischemia reperfusion injury after heart transplantation is believed to impair graft function and aggravate both acute and chronic rejection episodes. Objectives. To assess the possible protective potential of MK-886 and 3,5-diiodothyropropionic acid DITPA against global myocardial ischemia reperfusion injury after heart transplantation. Materials and Methods. Adult albino rats were randomized into 6 groups as follows: group I sham group; group II, control group; groups III and IV, control vehicles (1,2); group V, MK-886 treated group. Donor rats received MK-886 30 min before transplantation, and the same dose was repeated for recipients upon reperfusion; in group VI, DITPA treated group, donors and recipients rats were pretreated with DITPA for 7 days before transplantation. Results. Both MK-886 and DITPA significantly counteract the increase in the levels of cardiac TNF-α, IL-1β, and ICAM-1 and plasma level of cTnI (). Morphologic analysis showed that both MK-886 and DITPA markedly improved () the severity of cardiac injury in the heterotopically transplanted rats. Conclusions. The results of our study reveal that both MK-886 and DITPA may ameliorate global myocardial ischemia reperfusion injury after heart transplantation via interfering with inflammatory pathway.
