Bronchiolar fibrosis at 84 d post-exposure to 40 µg dose of CNT/F. The total area of bronchial/bronchiolar fibrosis per mm of basement membrane was quantified in two regions, both the least affected (A) and most affected (B) regions for comparison. *p < 0.05 versus DM. Scale bars represent mean ± standard error
