Abstract:
Objective To investigate the changes of antibrain-antibody (AB-Ab) in blood serum and the effect of AB-Ab on blood-brain barrier (BBB) and cerebral edema after the traumatic brain injury (TBI) in rabbits.Methods Forty-five New Zealand rabbits were randomly divided into control group (n =5),sham operation group (fenestration only without injury,n =15) and TBI group (severe lateral fluid percussion brain injury,n =15) according to the random number table.Sham and TBI animals were subdivided at postoperative 1,3,7 and 14 days.Level of AB-Ab,BBB permeability and brain water content were determined after operation.Results At each time point,serum AB-Ab level,BBB permeability and brain water content were higher in sham operation group and TBI group than in control group (P <0.05).At postoperative 3,7 and 14 days,serum AB-Ab level,BBB permeability and brain water content were higher in TBI group than in sham operation group (P < 0.05).Conclusion Serum level of AB-Ab is significantly increased after TBI along with synchronous changes in BBB permeability and brain water content,indicating that AB-Ab may be associated with the increase of BBB permeability and brain edema.
