Figure 2From: Detection of reactive oxygen species in isolated, perfused lungs by electron spin resonance spectroscopyThe ESR signal intensity in isolated perfused and ventilatedrabbit lungs during baseline conditions and in the presence of FeCl 2 /H 2 O 2 . Lungs were either perfused with Krebs-Henseleit buffer containing 1 mM CPH only (control) or in the presence of FeCl2 (1 μM, added at 0.5 h, FeCl2/H2O2). After 1.5 h, H2O2 was added to the buffer fluid by continuous infusion (8 μmol/min) in the FeCl2-perfused lungs. Bar indicates significant differences between the FeCl2/H2O2 group and control.Back to article page
