Abstract:
Hydrogen gas is neuroprotective in cerebral ischemia animal models. In this study, we tested the neuroprotective effects of hydrogen saline, which is safe and easy to use clinically, in a rat model of middle cerebral artery occlusion (MCAO). Sprague-Dawley male rats weighting 250-280 g were divided into sham, MCAO plus hydrogen saline and MCAO groups, and subjected to 90-min ischemia followed by 24 h of reperfusion. Hydrogen saline was injected intraperitoneally at 1 ml/100 g body weight. Infarct volume and brain water content were evaluated at different time points after reperfusion. Oxidative stress, inflammation, and apoptotic cell death markers were measured. Hydrogen saline significantly reduced the infarct volume and edema and improved the neurological function, when it was administered at 0, 3 and 6 h after reperfusion. Hydrogen saline decreased 8-hydroxyl-2'-deoxyguanosine (8-OHdG), reduced malondidehyde, interleukin-1β, tumor necrosis factor-α, and suppressed caspase 3 activity in the ischemic brain. These findings demonstrated hydrogen saline is neuroprotective when administered within 6 h after ischemia. Because hydrogen saline is safe and easy to use, it has clinical potentials to reduce neurological injuries.| Publish Year | 2011 |
