BACKGROUND/AIMS The purpose of this study was to examine the clinical presentations and pathological features of spontaneously necrotic choroidal melanomas. METHODS The clinical and histological features of patients who underwent enucleation for uveal melanoma from 1989 to 2012 at Emory University and were found to have spontaneously necrotic choroidal melanomas were retrospectively analyzed....

BACKGROUND The aim of the study is to investigate the healing effect of the bone-marrow derived mesenchymal stem cells (BM-MSCs) on ischemic colon anastomosis in systemic application and to recovery the adverse effect of ischemia. MATERIALS AND METHODS Fourty male Wistar Albino rats weigthing 250-300 g were divided into four equal groups (n=10 Group 1: control; ischemic left colonic anastomos...

dried oleander leaves at single lethal dose of 110 mg/kg body weight were administered orally to fivenative female goats. clinical signs of toxicosis in goats began to appear about 1 hr after receiving theoleander and included abdominal pain, ruminal atony and tympany, frequent urination, bradycardia,tachycardia, tachyarrhythmia, depression, weakness and convulsive movement and death at the end...

BACKGROUND AND PURPOSE Studies assessing the relationship between chronic poststroke language impairment (aphasia) and ischemic brain damage usually rely on measuring the extent of brain necrosis observed on MRI. Nonetheless, clinical observation suggests that patients can exhibit deficits that are more severe than what would be expected based on lesion location and size. This phenomenon is com...

R eperfusion injury is an issue of concern to every physician treating patients with acute myocardial infarction in the 1990s. For patients without specific contraindictions to therapy presenting for medical care early in the course of myocardial infarction, an attempt at reperfusion of ischemic, but not yet necrotic, myocardium is the current standard of clinical care. Whether a patient is tre...

Cardiac biomarkers such as CK-MB, troponins, and myoglobin provide the basis for the diagnosis of acute myocardial infarction (AMI) through identifi cation of the necrosis of myocardial cells in the heart. For emergency physicians, or any clinician evaluating and treating patients presenting to the hospital with acute coronary syndrome (ACS), ischemic changes on the 12-lead electrocardiogram or...

The effects of superoxide dismutase (SOD) alone or in combination with acidified sodium nitrite (NaNO2), a liberator of nitric oxide were examined in dogs after ischemia and reperfusion. Animals were divided into five groups. Left anterior descending coronary artery was occluded for 90 min followed by 4 hours of reperfusion with or without therapeutic interventions given preceding reperfusion. ...

Preconditioning of the myocardium with short episodes of sublethal ischemia will delay the onset of necrosis during a subsequent lethal ischemic insult. Ischemic preconditioning seems to involve a variety of stress signals which include activation of membrane receptors and signaling molecules such as protein kinase C, mitogen-activated protein kinases, opening of ATP-sensitive potassium channel...

Ischemic colitis is the most common subtype of intestinal ischemia usually resulting from vasospasm, vessel occlusion or mesenteric hypoperfusion. Neuroleptics have seldom been linked to ischemic colitis by blocking peripheral anticholinergic and antiserotonergic receptors inducing severe gastrointestinal paresis. We report a young patient with severe ischemic colitis requiring surgery due to n...

Abstract Coronary heart disease leading to myocardial ischemia is a major cause of failure. A hallmark failure fibrosis. Using murine model ischemia/reperfusion injury (IRI), we showed that, following IRI, in mice genetically deficient the central factor complement system, C3, necrosis was reduced compared with WT mice. Four weeks after ischemic period, C3 −/−mice had significantly less cardiac...
