elastase/hemorrhage

OBJECTIVE To investigate the mechanism by which activated leukocytes induce gastric mucosal lesions, we examined whether granulocyte elastase is involved in the formation of such lesions in a rat model of hemorrhagic shock. METHODS Prospective, randomized, controlled study. METHODS Research

Acute hemorrhagic pancreatitis was produced in pig to study serum concentration of elastase and its physiological role. Pancreatitis was induced in two groups of young pigs by the injection of autologous bile. One group was injected with autologous bile (0.5 ml/kg) at high pressure, and the second

The typical reverse passive Arthus reaction (RPA) was attained in rats by the instillation of a rabbit antiovalbumin serum into the lungs and intravenous injection of ovalbumin. Instillation of antiserum alone caused accumulation of polymorphonuclear leukocytes (PMN) and increased vascular

A pharmacokinetic model is described for testing of polymorphonuclear leukocyte (PMN) elastase inhibitors administered by intratracheal or aerosol dosing of hamsters. Acute lung injury, measured as hemorrhage occurring within hours after intratracheal instillation of human PMN elastase, correlated

A new series of benzoxazinone analogs were designed, synthesized, and assayed to determine their effects on superoxide anion generation and neutrophil elastase (NE) release in formyl-L-methionyl-L-leucyl-L-phenylalanine (FMLP)-activated human neutrophils. Of these, compounds 6-10 showed a potent

Argentine hemorrhagic fever (AHF) is a disease caused by Junin virus. In the acute phase, patients present hematologic and neurologic involvement with high levels of interferon-alpha and tumor necrosis factor-alpha (TNF-alpha. Nineteen patients with a confirmed diagnosis of AHF were studied: six

Toxoids of protease and elastase of Pseudomonas aeruginosa were successfully prepared by treatment with 8% formalin plus 0.2 m lysine and by 4% formalin respectively. The two toxoids proved sufficiently potent to elicit high antibody titers as estimated by both the enzyme-neutralizing and passive

The effects of common protective antigen (OEP) of Pseudomonas aeruginosa strain N10 (serotype 5) and OEP plus toxoids of protease and elastase from P. aeruginosa strains IFO 3080 and IFO 3455 were studied during an enzootic of hemorrhagic pneumonia caused by P. aeruginosa serotype 3 in mink. The

In patients with severe head injury or multiple trauma a multitude of inflammatory mediators are released. As in cerebral bleeding, elevations of body temperature can be observed even in the absence of bacterial infections. In order to evaluate the diagnostic significance of plasma elastase levels

We investigated the relationship between the levels of granulocyte elastase alpha 1-proteinase inhibitor complex (E-alpha 1-PI) in plasma and severe intraventricular hemorrhage (IVH) in very low birthweight infants. The concentrations of E-alpha 1-PI and the ratio of the concentrations of E-alpha

In acute pancreatitis, particularly in severe cases, polymorphonuclear neutrophil (PMN) elastase induces tissue damage in remote organs such as the lung, as well in the pancreas itself. Therefore, we examined the therapeutic effect of a specific synthetic inhibitor of PMN elastase (ONO-5046: Ono

The protective effects of a neutrophil elastase inhibitor (ONO-5046) on cerulein-induced pancreatitis followed by a septic challenge with intraperitoneal lipopolysaccharide (LPS) were studied in a rat model. Pancreatitis was induced by four intramuscular injections of cerulein (50 micrograms/kg at

This study evaluated the effects of aprotinin on plasma levels of elastase, platelet count, fibrinogen levels and postoperative bleeding. Thirty cardiac surgery patients were randomly chosen for this study. The protease inhibitor aprotinin was given in high doses to 20 patients before and during

Hemorrhagic shock followed by resuscitation (HSR) causes neutrophil sequestration in the lung which leads to acute lung injury (ALI). Neutrophil elastase (NE) is thought to play a pivotal role in the pathogenesis of ALI. This study investigated whether sivelestat, a specific NE inhibitor, can

BACKGROUND We describe a lethal complication of an aneurysm model in rabbits for saccular aneurysmal creation via endoluminal incubation with elastase. METHODS In 24 anaesthetized female New Zealand White rabbits, the right common carotid artery (CCA) was ligated distally to the arteriotomy. A 4F
