Figure 3

The effect of SB on histological analysis revealed typical pathological features by Masson staining. Pictures presented the histology of lung by Masson at three stages, 12 weeks, 24 weeks, and 36 weeks, respectively. (a) NC group; (b) COPD model group; (c) BUD group; (d) SB low-dose group; (e) SB middle-dose group; and (f) SB high-dose group. Original magnification, ×200. CS = cigarette smoking; SB = Scutellaria baicalensis; BUD = Budesonide; and NC = normal control.
