    Background/AimThe aim of this study was to investigate whether a hydrogen administration can produce neuroprotective effects after brain ischemia reperfusion in rats.Materials And MethodsA brain ischemia reperfusion injury was induced by a 2-h left middle cerebral artery occlusion (MCAO) using an intraluminal filament, followed by 46 h of reperfusion. A hydrogen-rich saline (1 mL/kg body weight i.p.) was administered at the beginning of reperfusion. Saline (1 mL/kg)-treated animals were used as the control. Sham-operated animals were also used. Subsequently, 48 h after the MCAO, histological alternations, heme oxygenase-1 (HO-1) expression, and levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in the cerebral cortex and the hippocampus were examined.ResultsHydrogen significantly alleviated brain tissue histological damage, promoted HO-1 expression, upregulated levels of SOD, and decreased the levels of MDA in brain tissue after the ischemia reperfusion injury.ConclusionThe results suggest that the neuroprotective effects of hydrogen may be mediated by promoting HO-1 expression and attenuated the oxidative injury.
