Figure 3. Blood occludin levels in MCAO rats without reperfusion correlate well with that with 5-min reperfusion.
(a) Blood occludin levels at the end of the indicated MCAO time and after 5-min reperfusion, as measured by ELISA. Data were presented as mean ± SEM (0 h, n = 12; 1.5, 3 and 4.5 h, n = 4). *P < 0.05 versus without reperfusion. (b) Linear regression analysis demonstrated a significant correlation between the blood occludin level before and after 5-min reperfusion; P < 0.0001 (Pearson correlation test).
