myocardial infarction is a common presentation of coronary artery disease and the leading cause of death worldwide. the present study was investigated potential resistance to ischemia-reperfusion (i/r) injuries following administration of methanolic (meoh) extract of scrophularia frigida (s. frigida) in isolated rat heart. male wistar rat hearts (n= 8-10) were isolated and allowed to equilibrat...

introduction: it has been reported that traumas such as transverse abdominal incision before myocardial ischemia result in a significantly decreased infarct size. this phenomenon is named remote preconditioning of trauma. since small skin burn is one of most common traumas, the effect of this injury on ischemia-induced arrhythmias and infarct size was investigated in a rat model of ischemia-rep...

recently a potent anti-inflammatory effect of hydroalcoholic extract of the aerial parts of the sterile stems of stachys inflata has been reported. this study examined whether hydroalcoholic extract isolated from aerial parts of non-flowering stems of stachys inflata (standardized to contain 4.5% caffeic acid derivatives) reduce myocardial infarct size arising from coronary artery occlusion (30...

this study intended to assess the efficacy of acute administration of natural honey on cardiac arrhythmias and infarct size when it is used during the normothermic ischemia in isolated rat heart. during 30 min of regional normothermic ischemia followed by 120 min of reperfusion, the isolated hearts were perfused by a modified drug free krebs-henseleit solution (control) or the solution containi...

objective(s): electrical inhomogeneity between ischemic and non ischemic myocardium is the basis of arrhythmia which occurs following coronary artery occlusion. the leakage of potassium from the ischemic region to the non ischemic region is very effective in the generation of these arrhythmias. the aim of this study is to research the effect of atp-dependent potassium (katp) channel blocker (gl...

introduction: in the current study, protective effect of natural honey applied during ischemia/reperfusion (i/r) was studied on infarct size in ischemic heartheart. methods: ischemic hearthearts (n=8 per group) were mounted on a langendorff apparatus at constant pressure then subjected to 30 min regional ischemia followed by 120 min reperfusion. in control group, the hearts were perfused by a m...

introduction: inhibition of renin angiotensin system represents an important approach in the management of cardiovascular diseases. the aim of this study was to explore the effects of pretreatment with non-hypotensive dose of angiotensin converting enzyme (ace) inhibitor, ramiprilat and angiotensin type 1 (at1) receptor blocker, losartan on myocardial infarct size and arrhythmias in a rat model...
