Figure 4

ECC-BYF III improved the pathological changes in COPD rats. (a) The representative image of the lung tissue pathology (HE; alveoli, 100×, scale bar: 200 μm; large airway, 400×, scale bar: 50 μm; small airway, 200×, scale bar: 100 μm). The green arrows indicate the fracture and fusion of the alveolar wall, orange arrows indicate inflammatory cell infiltration, red arrows indicate goblet cells, and blue arrows indicate small airway wall thickening. (b, c) Changes in the mean linear intercept (MLI) and mean alveolar number (MAN). All data are presented as the mean ± S (n = 6). aa versus the control group and bb versus the model group.
