(A), Representative photomicrographs of cross-sections from IR myocardium stained with NF-B (p65 subunit), MCP-1, ED-1 and TUNEL. Scale bar: 20 μm. (B), Quantification of the number of NF-B (p65 subunit) positive cells, the MCP-1-positive area, ED-1-positive leukocytes (monocytes) in IR myocardium and the number of TUNEL-positive cells in infarct border myocardium 24 hours after reperfusion. Data are mean±SEM (n = 5–8 per group). Data are compared using one-way ANOVA followed by Dunnett’s multiple comparison tests.
