Histopathological examination of asthmatic pulmonary tissue using H&E staining. Asthmatic changes were indicated by prominent interstitial pneumonia (arrows), focal hemorrhagia (arrows heads), and emphysema. The pathological remodeling coincided with the peribronchial cuffing, bronchial smooth muscle hypertrophy, and BALT hyperplasia. These features highlight the efficiency of our protocol in the induction of asthmatic changes using OVA.
