Effect of conditioned medium on neutrophil infiltration, apoptosis, and nitro-oxidative stress after ischemia/reperfusion injury. a Immunohistochemical scores of stainings for myeloperoxidase (MPO, × 400, scale 50 μm), nitrotyrosine (NT, × 200, scale 100 μm), caspase-3 (× 200, scale 100 μm), caspase-8 (× 200, scale 100 μm), caspase-9 (× 200, scale 100 μm), and caspase-12 (× 200, scale 100 μm). b Representative photomicrographs. CM, conditioned medium; IR, ischemia/reperfusion; BD, brain death. Values are mean ± SEM. *p < 0.05 vs. BD and ^#p < 0.05 vs. BD-IR. n = 6–9 rats
