Figure 6From: Combination of cyclosporine and erythropoietin improves brain infarct size and neurological function in rats after ischemic strokeTUNEL assay for indentifying apoptotic nuclei in brain infarct area. The number of apoptotic nuclei (yellow arrows) notably higher in group 2 (B) than in group 1 (A), group 3 (C), group 4 (D) and group 5 (E), significantly higher in group 3 and 4 than in group 1 and 5, and significantly higher in group 5 than in group 1, but no significant difference between group 3 and 4. Scale bars in right lower corner represent 20 μm (400x). †vs. other groups, p < 0.001 (ANOVA test). Symbols (*, †, ‡, §) indicate significance (at 0.05 level) (by Scheffe multiple-comparison post hoc test).Back to article page
