(A) Infarct size in COX-2 +/+
(n = 6), +/− (n = 7),
and −/− (n = 8) null mice 96 h after
MCA occlusion (MCAO). Ctx (E.C.), cerebral cortical infarct corrected
for swelling. (*, P < 0.05 from COX-2
+/+ and +/− mice; #, P < 0.05 from
COX-2 −/− and +/+ mice). (B) Infarct
size in COX-2-null mice 24 h after MCAO (n = 6
per group; *, P < 0.05 from COX-2
+/+ mice). (C and D) CBF reduction
in the center (C) and periphery (D) of
the ischemic region in COX-2 +/+ and −/− mice after
MCAO (n = 6 per group).
