Figure 2. Ischemia reperfusion group. A diffuse lymphocytic infiltration (*) was present in lung tissue.Histologic structurewas damaged. Infiltrative cells were increased, and muscle layer thickened in terminal bronchioles (TB). Bronchial lumen has cellular debris. Respiratory bronchioles were degenerative. Vascular smooth muscle cell increase and pericapillary edema were seen (hematoxylin-eosin 2A× 100, 2B × 400).
