Objective:To investigate the effect of lateral hydraulic injury(LFPI)on the integrity of blood-brain bar-rier in rats and its molecular mechanism.Methods:The rat LFPI model was prepared.Neurological impairment of rats was assessed by neurological severity score(NSS).The integrity of blood-brain barrier was assessed by dry/wet ratio test and Evans blue penetration test.The expressions of zonula occludens-1(ZO-1),occludin,and aquaporin 4(AQP4)were detected by Western Blot.Results:LFPI resulted in neurological dysfunction,increased cerebral water content,increased Evans blue permeability,decreased occludin and ZO-1 expression,and increased AQP4 expression.Conclusion:LFPI can cause cerebral edema and damage the integrity of blood-brain barrier in rats.
