Ischaemia/reperfusion, inflammatory responses and acute lung injury.

Effect of renal ischemia-reperfusion on lung injury and inflammatory responses in male rat

Objective(s):Acute kidney injury (AKI), a syndrome characterized by decreased glomerular filtration, occurs in every 1 of 5 hospitalized patients.  Renal ischemia-reperfusion, one of the main causes of AKI, is of particular importance in the setting of kidney transplantation. Materials and Methods: Sixty male rats were divided into four groups including control, nephrectomy, sham surgery and re...

Regulation of Acute Lung Inflammatory Injury

Genomic insights into acute inflammatory lung injury.

Acute lung injury (ALI) is a devastating syndrome (usually associated with sepsis) that represents a major healthcare burden in the United States. We have focused our studies on unraveling the genetic underpinnings of this syndrome utilizing a candidate gene approach to identify novel genes for ALI susceptibility. Two novel genes identified by this approach include pre-B cell colony-enhancing f...

Acute lung injury: how the lung inflammatory response works.

Acute lung injury in rodents (mice, rats) can be induced by intrapulmonary deposition of immunoglobulin (Ig)G immune complexes, which trigger an intense inflammatory response characterised by the influx of polymorphonuclear neutrophils (PMN), interstitial and alveolar oedema, and intra-alveolar haemorrhage [3]. This model of acute inflammation has been extensively evaluated in order to understa...

4'-Hydroxywogonin suppresses lipopolysaccharide-induced inflammatory responses in RAW 264.7 macrophages and acute lung injury mice

4'-Hydroxywogonin (4'-HW), a flavonoid, has been isolated from various plants and shown to inhibit NO production in macrophages. However, the molecular mechanisms and its in vivo activity have not been determined. Our study aimed to investigate the mechanisms underlying the anti-inflammatory effects of 4'-HW in vitro and in vivo. We showed that 4'-HW potently reduced the expression levels of CO...
