Quantitative analysis of contraction band and coagulation necrosis after ischemia and reperfusion in the porcine heart.
To assess the importance of contraction band necrosis (CBN) in reperfusion, CBN, coagulation necrosis (CN), and infarct size, expressed as CBN + CN, were quantitatively analyzed in 25 porcine hearts without collateral circulation. The left anterior descending coronary artery was ligated for 20, 30, 60, and 120 min and then reperfused for 8 hr (groups 1 to 4, respectively). Five hearts were not ...
متن کاملNecropsy study of the association between sudden cardiac death, cardiac isoenzymes and contraction band necrosis.
AIMS To assess whether a quantitative analysis of myocardial contraction bands could aid the postmortem identification of early myocardial infarction, especially if used in conjunction with cardiac isoenzyme activities. METHODS Sixty four coroner's necropsies were grouped by gross and histological findings into 26 cases of definite non-cardiac death, 12 cases of definite myocardial infarction...
متن کاملContraction-band Formation in Barnacle Myofibrils.
Contractions induced by adenosine triphosphate, in myofibrils isolated from the barnacle, Balanus aquilia, were observed with a phase microscope. The formation of contraction bands was well under way before the A-band came into contact with the Z-membrane. This is in disagreement with the hypothesis that contraction bands are formed when the A-band pushes against the Z-membrane.

متن کاملAcutely slipped gastric band with gastric necrosis and massive haemorrhage
We present a case of acute gastric band slippage with gastric necrosis and massive haemoperitoneum necessitating an emergency surgery. The patient presented with an 8h history of dysphagia, vomiting and epigastric pain. Initial examination was unremarkable, but within 6h the patient suddenly deteriorated with a distended peritonitic abdomen. At laparotomy the patient was found to have gastric b...
