Staining and quantification of TNFα (tumor necrosis factorα) positive cells. (A) upper panel: Bar graphs depict the percentage of cells positively stained for TNFα in specimens from left ventricular free wall. (B) lower panel: Original images showing TNFα staining of the left ventricle. Arrows indicate positively stained red cells. Scale bar = 20 µm. All data are given as means ± SEM. Significant differences (p < 0.05) versus control are indicated by *, significant differences versus control-minocycline by a §, significant differences versus CPB by a &.
