Effect of DHA treatment on FITC-dextran leakage at 72 h after MCAo. (A) Relative fluorescent intensity of FITC-dextran at six bregma levels in cortex, subcortex and ischemic hemisphere. (B) Total relative fluorescent intensity of FITC-dextran in cortex, subcortex and ischemic hemisphere. FITC-dextran leakage was decreased by DHA treatment compared to the corresponding saline group. Values are mean ± SEM; n = 6-7 rats per group. *Significantly different from corresponding saline group (p < 0.05, repeated measures ANOVA followed by Bonferroni tests).
