Figure 5 Quantitative Analysis of Myocardial Hemorrhage, Neutrophil Infiltration, and Cardiomyocyte Apoptosis After Ischemia-Reperfusion Injury

(A) Hemorrhage scores in the infarct zone of control pigs and pigs treated with iNO or IV-NTG. (B) Score of neutrophil infiltration (top) and MPO activity (bottom) in the infarct and border zones of animals receiving saline, iNO, or IV-NTG. (C) Percentage of TUNEL-positive cardiomyocytes in the infarct border zone. Data are expressed as mean ± SEM; *p < 0.05 versus control; p < 0.05 versus control and IV-NTG. Abbreviations as in Figures 1 and 4.
