Centriacinar bronchiolitis/alveolitis (dashed arrows) was induced by O-MWCNTs in three of four labs (ML1, ML2, ML3); one lab (ML4) found some deposition of O-MWCNTs in alveolar ducts with marginal inflammation.
Differentiated bronchiolar epithelium in alveolar ducts of rats exposed to ozone for 20 months.
In terms perhaps more useful for the pathologist on a daily basis, the term small airways includes membranous bronchioles, respiratory bronchioles, and alveolar ducts (29,36) (Figures 1 and 2).
For each emission wavelength, we photographed five images from the proximal alveolar region, which are alveoli located near the first alveolar ducts from the terminal bronchioles, the alveolar region most affected by particle deposition.
Hyaline membranes are composed of cellular and proteinaceous debris and appear as dense, glassy eosinophilic membranes lining the alveolar ducts and alveolar spaces (Figure 1).
These mice progressively accumulated soot, primarily in alveolar macrophages, and septal fibrosis and bronchiolization of alveolar ducts were observed in areas of soot accumulation.
In the original article of Myers et al, (1) the major pathologic finding was the presence of RB: clusters of slightly golden colored alveolar macrophages ("smoker's macrophages") in the lumens of respiratory bronchioles, alveolar ducts, and in the surrounding alveoli.
6 mm within the walls of respiratory bronchioles and adjacent alveoli; nodules, defined as fibrotic lesions up to 1 cm in size with round, irregular, or serpiginous borders and containing dust-laden macrophages; and interstitial fibrosis, defined as diffuse or irregular fibrosis of alveolar septa and/or alveolar ducts.
