elastase/necrosis

Leukocyte counts, plasma neutrophil elastase, tumor necrosis factor-alpha and C-reactive protein were determined serially in 19 patients undergoing elective coronary artery surgery with cardiopulmonary bypass. Neutrophil counts (mean +/- standard deviation 3.85 +/- 1.20 x 10(9)/L preoperatively)

Disturbances in arterial wall elastin metabolism appear to be important factors in atherosclerosis development. To evaluate this hypothesis, elastase-like activity was determined in cultured endothelial cells and their surrounding media after exposure to tumor necrosis factor-alpha (TNF),

Intrapulmonary activation of leukocytes and release of cellular mediators and enzymes are involved in the pathophysiology of the adult respiratory distress syndrome (ARDS). To investigate a possible role of local cytokines, we measured bronchoalveolar fluid (BALF) and plasma levels of tumor necrosis

BACKGROUND Our knowledge about the bidirectional interactions between brain and whole organism after trauma is still limited. It was the purpose of this prospective clinical study to determine the influence of severe head trauma (SHT) as well as trauma in different anatomic injury regions on

The aim of this study was to determine interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha) levels and neutrophil elastase (NE) activity in peri-implant crevicular fluid (PICF) of smoker and nonsmoker patients, and to investigate their relationships with clinical parameters. A total

Cytokine levels during infection and sepsis have been extensively studied in the past. In contrast to the excellent data on tumour necrosis factor alpha (TNF-alpha), interleukin 8 (IL-8), and polymorphonuclear (PMN) granulocyte elastase (PMN-E) concentrations in blood, little is known about cytokine

We have related experimentally induced post-cardiac transplant coronary arteriopathy to increased elastolytic activity, IL-1beta, fibronectin-mediated inflammatory and smooth muscle cell (SMC) migration, and SMC proliferation. Since our in vitro studies show that a serine elastase releases SMC

A dissecting aneurysm of the right internal carotid artery was found in a 22-year-old man, who rapidly became unconscious and hemiparetic after an accident occurring during sport. The dissection was limited to the intima and internal elastic lamina. Patterns of cystic medial necrosis with mucoid

Cultured human umbilical vein endothelial cells inhibited tumor necrosis factor-alpha release from whole blood or isolated mononuclear cells exposed to endotoxin. In contrast, the endothelial cells augmented neutrophil elastase release in the same blood. A protein with these functional properties

Plasma levels of tumor necrosis factor-alpha (TNF alpha), interleukin-1 (IL-1), and interleukin-6 (IL-6) were monitored after intravenous administration of Escherichia coli endotoxin with or without ibuprofen pretreatment to healthy volunteers. Intravenous endotoxin (n = 7) resulted in elevated

To localize the protease(s) involved in shedding of tumor necrosis factor receptors (TNF-R) from activated neutrophils (PMN) (Porteu, F., and C. Nathan (1990) J. Exp. Med. 172, 599-607), we tested subcellular fractions from PMN for their ability to cause loss of TNF-R from intact cells. Exposure of

Although the role of tumor necrosis factor-alpha (TNF) as mediator of inflammation is now well established, its interactions with polymorphonuclear neutrophils (PMN) are not fully understood. Therefore, we investigated the possible hydrolytic action on TNF of intra-lysosomal enzymes released by

BACKGROUND Abdominal aortic aneurysm (AAA) involves leukocyte recruitment, inflammatory cytokine production, vascular cell apoptosis, neovascularization, and vascular remodeling, all of which contribute to aortic dilatation. Tumor necrosis factor-like weak inducer of apoptosis (TWEAK) is a cytokine

Proinflammatory cytokines, lipopolysaccharide (LPS), and neutrophil elastase (NE) have been implicated in the induction of hypersecretion of respiratory mucus. In this study, we demonstrated that interleukin-1beta (IL-1beta) increased MUC2 and MUC5AC mRNA levels 2- to 3-fold in a time- and

Tumor necrosis factor (TNF) has been proposed as an important mediator of the inflammatory response in acute lung injury. To better understand polymorphonuclear leukocyte (PMN) activation during acute lung injury, we evaluated the effects of TNF on several in vitro PMN functions, including
