3. Fig 2
Analysis of variance for repeated measures, which consists of all measurements made during the reperfusion period for oxygenation, significantly differed (p = 0.001) between the surfactant group (SURF [solid line] and the control group (CON [broken line]). Oxygenation: partial arterial oxygen pressure/fraction of inspired oxygen (PaO2/FiO2 ratio). Timepoints: baseline (BL); 10 minutes before occlusion of the right lung (BO); 1 hour after occlusion of the right side (T1); 2 hours after occlusion of the right side (T2); 3 hours after occlusion of the right side (T3); 4 hours after occlusion of the right side (T4); 5 hours after occlusion of the right side (T5); and 6 hours after occlusion of the right side (T6).

4. Fig 3
Bronchoalveolar lavage (BAL) neutrophil count at the end of experiment (BAL3) was significantly higher (p = 0.03) in the control group (CON [gray bars]) compared with the surfactant-treated group (SURF [black bars]). BAL1 = 24 hours after acid injury before retrieval at the end of 24 hours of ventilation (left lung); BAL2 = right lung without injury before retrieval at the end of 24 hours of ventilation; and BAL3 = transplanted left lung, at the end of experiment.

5. Fig 4
Bronchoalveolar lavage (BAL) interleukin (IL)-6 levels. A significantly lower IL-6 level was observed in the surfactant group (SURF) compared with the control group (CON) in BAL3 (p = 0.03). BAL1 = 24 hours after acid injury before retrieval at the end of 24 hours of ventilation (all left lungs from 2 groups, n = 12]); BAL2 = right lung without injury before retrieval at the end of 24 hours of ventilation (all right lungs from both groups, n = 12); and BAL3 = transplanted left lung, at the end of experiment (SURF, n = 6; CON, n = 4).

Serum interleukin (IL)-8 level was higher in the control group (CON) compared with the surfactant group (SURF) at 3 hours (T3 [gray bars]) and 6 hours (T6 [black bars]) after left lung dependent reperfusion (p = 0.03). (Open bars = baseline.)

Myeloperoxidase activity in lung tissue at the end of experiment was significantly higher (p = 0.03) in the control group (CON) compared with the surfactant group (SURF).

Minimal surface tension in bronchoalveolar lavage (BAL). BAL1 = 24 hours after acid injury before retrieval at the end of 24 hours of ventilation (left lung) (all left lungs from 2 groups, n = 12); BAL2 = right lung without injury before retrieval at the end of 24 hours of ventilation (all right lungs from both groups, n = 12); and BAL3 = transplanted left lung, at the end of experiment (surfactant group [SURF], n = 6; control group [CON], n = 4). BAL3 SURF versus BAL3 CON, p = 0.03.

(A) The surfactant group showed relatively normal structure with reduced cellular infiltration. (B) The control group showed alveolar congestion, hemorrhage, and neutrophil and macrophage infiltration.
