Xanthine oxidase (XO)-generated toxic O2 metabolites appear to contribute to reperfusion injury, but the possibility that XO is involved in hyperoxic or neutrophil elastase-mediated injury has not been investigated. We found that lungs isolated from rats fed a tungsten-rich diet had negligible XO activities and after exposure to hyperoxia developed less acute edematous injury during perfusion with buffer or purified neutrophil elastase than XO-replete lungs from control rats which had been exposed to hyperoxia. In parallel, tungsten-treated XO-depleted cultured bovine pulmonary arterial endothelial cells made less superoxide anion and as monolayers leaked less 125I-labeled albumin after exposure to neutrophil elastase than XO-replete endothelial cell monolayers. Our findings suggest that XO-derived O2 metabolites contribute to acute edematous lung injury from hyperoxia directly and by enhancing susceptibility to neutrophil elastase.
