Hydrogen-rich saline reduces lung injury induced by intestinal ischemia/reperfusion in rats

In Animal studies, Lungby CHESS

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. Hydrogen-rich saline attenuates lung injury induced by intestinal I/R.
