Fluoxetine downregulated MMP-9 expression and prevented degradation of the tight junction proteins in the ipsilateral cortex at 24 h after SAH. a Representative western blot bands of MMP-9, occludin, claudin-5, and ZO-1. b Densitometric quantification of MMP-9. **p < 0.01 vs sham. ^##p < 0.01 vs SAH+vehicle. n = 6/group. c Densitometric quantification of occludin. **p < 0.01 vs sham. ^#p < 0.05 vs SAH+vehicle. n = 6/group. d Densitometric quantification of claudin-5. **p < 0.01 vs sham. ^##p < 0.01 vs SAH+vehicle. n = 6/group. e Densitometric quantification of ZO-1. **p < 0.01 vs sham. ^#p < 0.05 vs SAH+vehicle. n = 6/group
