The serial measurement of the oxidative stress response in Case 1 after lung transplantation. The gray bar shows the treatment of infections by intravenous antibiotics. During this period, d-ROM levels are significantly (p<0.01) higher during treatment of infection (n=23, 401) than during stable conditions (n=32, 277), and after airway silicone stent insertion they seem to have improved. d-ROM: diacron-reactive oxygen metabolite, BAP: biological antioxidant activity of plasma, POD: postoperative day, U.CAAR: Carratelli units
