متن کاملEffects of Postconditioning, Preconditioning and Perfusion of L-carnitine During Whole Period of Ischemia/ Reperfusion on Cardiac Hemodynamic Functions and Myocardial Infarction Size in Isolated Rat Heart
OBJECTIVE(S) In the present work, the effects of L-carnitine (LC) on postischemic cardiac hemodynamic functions and infarction size were studied in isolated rat heart. MATERIALS AND METHODS The hearts were subjected to 30 min regional ischemia followed by 120 min reperfusion. Then they were perfused by a drug-free or LC-enriched Krebs-Henseleit (K/H) solution during ischemia/ reperfusion (I/R...
متن کاملComparison between the effects of L-Carnitine and Acetyl-L-Carnitine on myocardial infarction size in ischemic heart
Introduction: In the present study, potential differences between the effects of L-carnitine (LC) and acetyl-Lcarnitine (ALC) on ischemia/reperfusion (I/R)-induced myocardial infarction size were investigated. Methods: Male Wistar rats were randomly divided into five groups and then anesthetized by sodium pentobarbital. Hearts of the animals were removed and quickly mounted on a Langendorff ...
متن کاملPreconditioning effects of oxytocin in reducing cardiac arrhythmias in a rat heart regional ischemia-reperfusion model
Abstract Introduction: Occurrence of cardiac arrhythmias and myocardial infarction are two main deleterious events that are caused by ischemia-reperfusion (IR) injury in the heart. Cardiac preconditioning represents the most potent method of rescuing heart tissue from undergoing irreversible ischemic damage. The aim of the present study was to evaluate oxytocin (OT) cardioprotective effect...
متن کاملEffects of Acetyl-L-Carnitine on Cardiac Arrhythmias and Infarct Size in Ischemic-Reperfused Isolated Rat Heart
Objective(s) This study aimed to examine whether acetyl-L-carnitine (ALC) was able to reduce cardiac arrhythmias and infarct size in the ischemic-reperfused isolated rat heart. Materials and Methods The isolated hearts were mounted on a Langendorff apparatus then perfused by a modified Krebs-Henseleit solution during 30 min regional ischemia and 120 min reperfusion (control) or by enriched K...
متن کاملEffects of Total Extract of Dracocephalum moldavica on Ischemia/Reperfusion Induced Arrhythmias and Infarct Size in the Isolated Rat Heart
Objective(s) Dracocephalum moldavica (D. moldavica) have been traditionally used as a cardiotonic agent in the folk medicine of some regions of Iran. In the present study, effects of total extract of D. moldavica on ischemia/reperfusion induced arrhythmias and infarct size investigated in isolated rat heart. Materials and Methods The isolated hearts were mounted on a Langendorff apparatus th...
