The pathological changes in the lungs of mice in different groups after OVA inhalation. a: Group A & asthma model group, b: Group A & control group, c: Group B & asthma model group, d: Group B & control group, e: Group C & asthma model group, f: Group C & control group, g: Group D & asthma model group and h: Group D & control group. The mice in the control group showed clear structures in the bronchus and alveoli with arranged neatly airway epithelial cells, intact lumen, no infiltration of inflammatory cells (magnification: × 200). The mice in the OVA-induced asthmatic model group showed disordered structures in the lung tissue, with widened alveolar septum, capillary dilatation, congestion, and a large number of inflammatory cell and neutrophil infiltrations (magnification: × 200)
