Vascular reactivity following ischemia/reperfusion.
Data in the literature supports the hypothesis that reactive oxygen species generated in the vascular wall alter vascular regulation. At present the majority of the literature tends to suggest that oxidant induced damage on the smooth muscle cell impair vasoconstriction. However, direct action of oxidants on the smooth muscle cell impair vasoconstrictor function. Differences in studies in the l...
متن کاملLoss of ectonucleotidases from the coronary vascular bed after ischemia-reperfusion in isolated rat heart
BACKGROUND Ectonucleotidase plays an important role in the regulation of cardiac function by controlling extracellular levels of adenine nucleotides and adenosine. To determine the influence of ischemia-reperfusion injury on ectonucleotidase activity in coronary vascular bed, we compared the metabolic profile of adenine nucleotides during the coronary circulation in pre- and post-ischemic heart...

متن کاملDoes Heart Affect Peripheral Vascular Resistance Following Myocardial Ischemia and Reperfusion?
Objective(s) The aim of this study was to investigate the overall effect of cardiac vasoactive factors during coronary occlusion and reperfusion on peripheral vascular tone, using a sequential isolated rabbit heart-ear perfusion model. Materials and Methods Isolated ears were perfused with the effluent of isolated hearts subjected to ischemia (30 min) and reperfusion (180 min, n=6). The comp...
متن کاملRemifentanil ameliorates intestinal ischemia-reperfusion injury
BACKGROUND Intestinal ischemia-reperfusion injury (IRI) can occur in clinical scenarios such as organ transplantation, trauma and cardio-pulmonary bypass, as well as in neonatal necrotizing enterocolitis or persistent ductus arteriosus. Pharmacological protection by pretreating ("preconditioning") with opioids attenuates IRI in a number of organs. Remifentanil appears particularly attractive fo...
