Improvement of ventilation-induced lung injury in a rodent model by inhibition of inhibitory κB kinase.

Background: Inhibition of nuclear factor κB (NF-κB) activation is a well-know strategy to ameliorate ventilation-induced lung injury (VILI). Inhibitory κB kinase (IKK) plays a key role in the regulation of NF-κB activation. In this study, we determined whether inhibition of IKK by an IKK inhibitor exerts lung protection in a rat model of VILI.

Galangin dampens mice lipopolysaccharide-induced acute lung injury.

Galangin, an active ingredient of Alpinia galangal, has been shown to possess anti-inflammatory and antioxidant activities. Inflammation and oxidative stress are known to play vital effect in the pathogenesis of acute lung injury (ALI). In this study, we determined whether galangin exerts lung protection in lipopolysaccharide (LPS)-induced ALI.

Inhaled neutrophil elastase inhibitor reduces oleic acid-induced acute lung injury in rats.

Rationale: Neutrophil elastases (NE) play an important role in the pathogenesis of acute lung injury (ALI). NE activities are significantly increased in serums and lungs of patients or animals with ALI. Intravenous infusion (IV) of Sivelestat, an NE inhibitor, can reduce ALI.

Attenuation of hyperoxia-induced lung injury in rats by adrenomedullin.

Oxidative stress and inflammation are involved in the pathogenesis of acute lung injury (ALI). Adrenomedullin (AM) is an endogenous peptide with anti-inflammatory and antioxidant properties. This study investigated that whether AM treatment may ameliorate hyperoxia-induced ALI in rats via inhibition of oxidative stress and inflammation.
