['Hydrogen has been reported to selectively reduce the hydroxyl radical, the most cytotoxic of reactive oxygen species. In this study we investigated the effects of hydrogen-rich saline on the prevention of lung injury induced by intestinal ischemia/reperfusion (I/R) in rats.', 'Male Sprague-Dawley rats (n=30, 200-220g) were divided randomly into three experimental groups: sham operated, intestinal I/R plus saline treatment (5ml/kg, i.v.), and intestinal I/R plus hydrogen-rich saline treatment (5ml/kg, i.v.) groups. Intestinal I/R was produced by 90min of intestinal ischemia followed by a 4h of reperfusion.', 'Hydrogen-rich saline treatment decreased the neutrophil infiltration, the lipid membrane peroxidation, NF-kappaB activation and the pro-inflammatory cytokine interleukin IL-1beta and TNF-alpha in the lung tissues compared with those in saline-treated rat.'] Does hydrogen-rich saline reduce lung injury induced by intestinal ischemia/reperfusion in rats?
