The values are expressed as mean ± SD. Statistical significance was determined by a one-way ANOVA with Bonferroni correction.
P < 0.05 versus sham group.
P < 0.05 versus vehicle group using between group comparisons with Bonferroni correction. CBF, cerebral blood flow; GBC, glibenclamide; TH, therapeutic hypothermia.
