Scutellaria baicalensis Attenuates Airway Remodeling via PI3K/Akt/NF-κB Pathway in Cigarette Smoke Mediated-COPD Rats Model

Figure 2

The effect of SB on histological examination by HE staining. Rats were exposed to CS for 12, 24, and 36 weeks with SB (1.5, 3, and 6 mg/(kg⋅d)) or BUD (0.2 mg/(kg⋅d)). Lung tissue was stained using H&E being examined. (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; HE = hematoxylin and eosin staining; SB = Scutellaria baicalensis; BUD = Budesonide; and NC = normal control.
