Abstract:
Objective To explore the protective mechanisms of hydrogen-rich saline on renal ischemiareperfusion injury.Methods Mice were divided in to 3 groups:control (sham operation),ischemia-reperfusion (IR) and ischemia-reperfusion+ hydrogen-rich saline (HRS).Mice in IR+ HRS group were administrated HRS by intravenous injection 3days and 1min before operation and 4 times in the following 2hours after operation.Mice in control and IR group were administrated normal saline as the same volume and frequency with IR + HRS group.Mice were sacrificed 24 hours after operation,creatinine and urea nitrogen in serum were detected by biochemical analyzer,MDA and SOD level were detected by spectrophotometer,expression of Bcl-xl,Bcl2,Bak,Bax,Cleaved Caspase-3 proteins level were detected by western blot.Results Compared to IR group,creatinine,urea nitrogen,MDA level decreased significantly after HRS consumption.SOD enzyme activity increased significantly after HRS consumption.HRS treatment down-regulates expression of Bak,Bax and Cleaved Caspase-3 protein level,and up-regulates expression of Bcl2,and Bcl-xl protein level.Conclusion HRS eliminates ROS and elevates antioxidant activity in renal after IR,besides,HRS also regulate apoptosis signal pathway to protect IR injury in renal.
