elastase/inflammation

BACKGROUND We previously reported the isolation of aptamer irreversible inhibitors of human neutrophil elastase. We now report on the application of aptamer technology to the field of diagnostic imaging. RESULTS The enzyme elastase has been reported to bind to the surface of activated neutrophils.

We have examined the effect of ONO-5046.Na, a synthetic specific inhibitor of neutrophil elastase, on lipopolysaccharide (LPS)-induced acute lung inflammation. Syrian golden hamsters were injected intraperitoneally with either 300 mg.kg-1 of ONO-5046.Na or saline, 30 min before and 1 h after

BACKGROUND Among the serine proteases, neutrophil elastase is a powerful cytotoxic enzyme and plays a pivotal role in the inflammatory response associated with cardiopulmonary bypass. This study assesses the effects of the specific inhibition of neutrophil elastase by a novel, potent,

BACKGROUND 'Post-Perfusion Syndrome' (PPS) after cardiopulmonary bypass (CPB) is known to be evoked by inflammatory reactions. The hypothesis of a pathogenetic role for the neutrophil granulocytes in this inflammation would be strengthened if elevated concentrations of a neutrophil product such as

Elastase activity and concanavalin A (Con A) low affinity bovine lactoferrin (bLf) molecule were detected in mammary gland secretions (MGSs) from mammary glands (MGs) with clinical staphylococcal mastitis. Changes in clinical symptoms correlated with increases in both elastase activity and the

OBJECTIVE A neutrophil elastase inhibitor FR901277 was examined for its inhibitory effect on degradation of natural substrate elastin in vitro, and on acute inflammatory states and pulmonary emphysema in vivo. METHODS Elastin-congo red was used as a substrate for elastin degradation assay. Paw edema

BACKGROUND Recent evidence suggests that pancreatitis-associated hepatic injury is regulated by inflammatory mediator production. Our laboratory demonstrated in vitro that pancreatic elastase is a pancreatic enzyme that can induce inflammatory cell cytokine production. Therefore we now explore the

BACKGROUND A commercially available ELISA kit for fecal elastase measurement can be used in the diagnosis of exocrine pancreatic insufficiency (EPI) in dogs. However, other causes of diarrhea also may affect fecal elastase concentration. OBJECTIVE This study was undertaken to determine whether

The present study was undertaken to estimate elastase in biological fluids and assess its usefulness as an indicator of inflammation/infection. Elastase was measured in seminal plasma, serum, urine, and cervical specimens using a specific substrate and was expressed in arbitrary units (AU). It was

Neutrophil elastase is secreted by inflammatory cells during airway inflammation and can elicit airway hyperreactivity in vivo. Elastase can degrade multiple components of the extracellular matrix. We hypothesized that elastase might disrupt the connections between airway smooth muscle (ASM) cells

Elastase-inhibitor complex was assessed by immunoassay in the seminal plasma of 312 men attending the outpatient infertility clinic. Using receiver operating characteristic (ROC) curve analysis, elastase at the cut-off value of > or =290 ng/ml was shown to be efficient (sensitivity 79.5%,

Elastase, a specific inflammatory parameter of polymorphonuclear (PMN) granulocytes, was quantified with a sensitive enzyme immunoassay in the ejaculates of 188 patients consulting the andrological outpatient service. Correlations of the elastase concentrations to other parameters used up to now for

OBJECTIVE To compare elastase concentrations in gingival crevicular fluid (GCF) from individual sites of smokers and non-smokers. METHODS Twelve pairs of smokers and non-smokers with untreated, moderate to advanced chronic inflammatory periodontal disease were matched for gender, age, ethnicity and

BACKGROUND Exposure to ultrafine particles (<100 nm in diameter) is postulated to cause chronic obstructive pulmonary disease (COPD). However, the mechanism remains to be elucidated. OBJECTIVE We aimed to evaluate whether ultrafine particle exposure causes the infiltration of inflammatory and

In viral myocarditis, inflammation and destruction of cardiac myocytes leads to fibrosis, causing progressive impairment in cardiac function. Here we show the etiologic importance of serine elastase activity in the pathophysiology of acute viral myocarditis and the therapeutic efficacy of an
