Figure 6 NOx in Myocardial Tissue and Plasma During Ischemia-Reperfusion Injury

(A) Myocardial oxidized nitric oxide species (NOx) levels in the infarct, border, and remote zones of the porcine heart after 40 min of ischemia and 4 h of reperfusion. Data are expressed as mean ± SEM. *p < 0.05 compared with border and remote zone in iNO; p < 0.01 versus infarct zone in IV-NTG pigs; and p < 0.001 versus infarct zone in control animals. n = 8 per group. (B) Plasma NOx levels after 45 min of ischemia, and 30, 60, 120, and 240 min of reperfusion. Data are expressed as mean ± SEM. *p < 0.05. n = 4 per group. Abbreviations as in Figure 1.
