Acute mesenteric ischaemia.
The experience of acute mesenteric ischaemia at St Vincent's Hospital, Melbourne, has been reviewed over 17 years. The mortality remains appallingly high. This applies particularly to those patients who had thrombosis of the superior mesenteric artery, amongst whom the mortality in this series was 97%. The mortality was slightly less in the group suffering from embolic occlusion of the superior...
متن کاملSarcolemmal permeability changes during ischaemia and reperfusion: release of survival factors.
Enzyme release by ischaemic myocardium has been used as a hallmark of the infarction process for several decades: in the clinical setting, deterioration of cell membrane integrity, as evidenced by the release of macromolecules such as creatine kinase and lactate dehydrogenase, has been used as quantitative indication of myocardial infarction. Leakage of membrane-impermeable molecules due to sar...
متن کاملLongitudinal quantification of radical bursts during pulmonary ischaemia and reperfusion.
OBJECTIVES Pulmonary ischaemia-reperfusion injury (IRI) is associated with several life-threatening pulmonary disorders, and may severely compromise the outcome of lung transplantation. Highly reactive molecules such as superoxide, nitric oxide (NO) and peroxynitrite (ONOO(-)) are presumed to contribute to IRI pathogenesis, but this assumption is based on indirect measurements. We use electron ...
متن کاملGut and vessel alterations induced by mesenteric ischaemia/reperfusion in rats.
A rat model of transient occlusion of the superior mesenteric artery was used to study the intestinal and vascular injury induced by ischaemia/ reperfusion (I/R). A pronounced intestinal injury was observed, ranging from hyperaemia to severe haemorrhagic necrosis and bleeding. The length of the damaged intestinal segments reached 58.6% of the small intestine with a decrease of the wet weight in...
متن کاملVascular ischaemia and reperfusion injury.
Although restoration of blood flow to an ischaemic organ is essential to prevent irreversible tissue injury, reperfusion per se may result in a local and systemic inflammatory response that may augment tissue injury in excess of that produced by ischaemia alone. Cellular damage after reperfusion of previously viable ischaemic tissues is defined as ischaemia-reperfusion (I-R) injury. I-R injury ...
