Fig. 6. Western blot analyses of AQP4 (A , B ) and measurements of brain wet-to-dry (W/D) weight ratio after 24 and 72 h of reperfusion (C ). Data are presented as mean ± SD. (B ) *P < 0.05 versus ischemia–reperfusion (I/R), P1, and P2 groups. (C ) *P < 0.01 versus I/R, P1, and P2 groups. AQP4 = aquaporin-4; GAPDH = glyceraldehyde-3-phosphate dehydrogenase; KD = kilodalton.
