Protective Effects of Platycodin D3 on Airway Remodeling and Inflammation via Modulating MAPK/NF-κB Signaling Pathway in Asthma Mice

Figure 4

(a) HE staining of asthma mice lung tissues, PD₃ treatment alleviated airway pathological lesion. Blue arrows pointed the inflammatory cells immersed in the lung tissues. The 200x scale bar was 100 μm; the 400x scale bar was 50 μm. (b) AB-PAS staining of asthma mice lung tissues, PD₃ treatment alleviated airway mucus secretion and goblet cells hyperplasia. The 200x scale bar was 100 μm; the 400x scale bar was 50 μm. PD3, platycodin D3.
