Harmine treatment significantlyreduces the escape latency at 3 and 5 days, compared with the TBI group. Post

8、-TBI administration of Harminesignificantly improves the motor function recovery of the rats at 1, 3 and 5 days following TBI, compared with the TBIgroup without Harmine treatment. The neuronal survival rate in the Harmine-treated group is significantly increased,compared with the TBI group. Adminis

9、tration of Harmine results in marked elevation in the expression of GLT-1,compared with the TBI group. The administration of Harmine significantly reduces the expression of caspase 3,compared with the TBI group4.PROTOCOLAnimal Rats4Administration 4 A total of 150 male Sprague-Dawley rats (age, 10-12

10、 weeks; weighing, 280-320 g; are used in the present study. Therats are randomly divided into three groups: Sham-operated group (sham; n=15); the TBI group (TBI; n=35) and theTBI + Harmine-treated group (Harmine; n=35). Harmine is administered immediately following TBI (i.p, 30 mg/kgper day) for up

11、to 5 days. The sham and TBI groups receive equal volumes of 0.9% saline solution (i.p.). The rats aregrouped as follows for examination of behavioral recovery: Sham, n=3; TBI, n=7; and Harmine, n=7. Following TBI,the NSS is evaluated at 1, 3 and 5 days.
