Abstract:
Objective To study the protective effect of saturated hydrogen saline against cerebral ischemia-reperfusion injury and the related mechanism. Methods Rat middle cerebral artery occlusion (MCAO) models were established by thread ligation of the middle cerebral artery. The rats were sacrificed 24 h later. The cerebral infarction volume was determined by TTC staining, the water content in brain tissue by dry-wet weight method, the degree of cerebral cells by Nissl staining, and the levels of IL-1β and TNF-α in the ischemic cerebral tissues by ELISA. Results Compared with control group, hydrogen saline decreased the brain water content and cerebral infarction volume, and increased the quantity of nissel’s body in the cortex; meanwhile, it also significantly decreased the concentrations of IL-1β and TNF-α in brain tissue(P<0. 05). Conclusion Hydrogen saline can alleviate the cerebral ischemia-reperfusion injury, probably by inhibiting the inflammation response.
