Objective(s): According to recent the findings, sulfur dioxide (SO2) is produced by the cardiovascular system, influencing some major biological processes. Based on previous research, SO2 exhibits antioxidant effects and inhibits apoptosis following cardiac ischemia/reperfusion. Therefore, the objective of the current study was to examine the neuroprotective impact of SO2 following global cereb...

 In emergency department, physicians can diagnose pulseless electrical activity, asystole, pericardial effusions, ischemic heart disease, wall motion abnormalities, valvular cardiac disease volume status or global cardiac function evaluating with electrocardiographic findings or using bedside c...

introduction: this study was aimed to investigate the effects of postconditioning by natural honey on cardiac arrhythmias in the ischemic isolated rat heart. methods: male wistar rats were divided into four groups then anesthetized by sodium pentobarbital. the animal hearts were removed and quickly mounted on a langendorff apparatus and perfused under constant pressure by a modified krebs-hense...

Erythropoietin has recently been shown to have effects beyond hematopoiesis such as prevention of neuronal and cardiac apoptosis secondary to ischemia. In this study, we evaluated the in vivo protective potential of erythropoietin in the reperfused rabbit heart following ventricular ischemia. We show that "preconditioning" with erythropoietin activates cell survival pathways in myocardial tissu...

OBJECT To investigate the effect of lung Ischemia-reperfusion injury on cardiac muscle. METHODS SD rats were randomly divided into the following four groups: sham operation group (TS group); experimental control group (TG group); curcumin group (TC group); dexamethasone group (TM group). After 4 h and 24 h of lung ischemia-reperfusion, the cardiac muscle was collected. We measured the concent...

Hypertension is the risk factor of serious cardiovascular diseases, such as ischemic heart disease and atherosclerosis. The aim of the present study was to analyze the development of cardiac tolerance to ischemia in neonatal spontaneously hypertensive rats (SHR) and possible protective effect of ischemic preconditioning (IP) or adaptation to intermittent high-altitude hypoxia (IHAH). For this p...

Elevated cardiac triacylglycerol (TAG) content is traditionally equated with cardiolipotoxicity and suggested to be a culprit in cardiac dysfunction. However, previous work demonstrated that myosin heavy-chain-mediated cardiac-specific overexpression of diacylglycerol transferase 1 (MHC-DGAT1), the primary enzyme for TAG synthesis, preserved cardiac function in two lipotoxic mouse models despit...

bipolar cardiac electrograms were obtained in dogs from ischemic areas following temporary coronary artery ligation. characteristic alterations from the controls were observed, including increase in dura tion, decrease in amplitude and alterations in configuration. these changes were found to be completely reversible upon restoration of coronary flow. the bipolar electrogram has been recommende...

We tested the hypothesis that cardiac ischemia uncouples the beneficial interaction among hyperkalemia, acidosis, and raised plasma catecholamines when these chemicals are changed to mimic their exercise levels. Potassium chloride, lactic acid, and norepinephrine (NE) were infused intravenously for 2 min into anesthetized, artificially ventilated, thoracotomized rabbits during either occlusion ...
