From: Fipronil induces lung inflammation in vivo and cell death in vitro
H&E staining of mice lungs. Lung sections from control mice (a-b) have normal lung histology of alveolar septa (arrows) and bronchiolar (B) epithelium (Ep). The oral treatment with fipronil caused lung inflammation and lung sections (c-d) show inflammation (asterisks) around bronchioles (B) and blood vessels (BV). Lung sections from mice treated intranasally with fipronil (e-g) show septal congestion in septa (arrows; e)), cells adhering (arrows) to endothelium (En; f) and swollen epithelium (Ep) of bronchioles (B; 1 g).
