Figure 4. Baicalein suppresses OVA-induced inflammatory cell recruitment. (A) Histologic lung sections were stained with H&E, which showed that Baicalein reduces inflammatory cell recruitment and infiltration into the airway. Image are shown at 200× magnification with a scale bar representing 100 μm. (B) Lung inflammatory scores were assessed by histological analysis of lung tissues. Baicalein reduced the numbers of total cells (C) and eosinophils (D) in BALF following OVA challenge (Results are presented as the mean ± SEM. n = 6 mice per group; ##P < 0.01 compared with the control group; *P < 0.05, **P < 0.01 compared with the OVA/Vehicle group).
