Fig. 7. Conjugated diene activity in muscle was measured as a marker of oxidative stress during ischemia–reperfusion. Low conjugated diene content was observed in patients receiving inhaled nitric oxide (NO) compared with the control group. ABS = acrylonitrile butadiene styrene.  P < 0.05, † compared with baseline values and ‡ compared with inhaled NO reperfusion group.
