Histopathological changes after single challenge of PM-b. A Experimental schedule. PM-b was intratracheally injected at day 0, and mice were euthanized on days 7 (n = 5) and 14 (n = 5). B Representative images of the lung of mice on days 7 and 14. Pulmonary histopathological changes after single challenge of PM-b were evaluated by three different types of staining (HE: Hematoxylin-Eosin staining; MT: Masson’s Trichrome staining; SR: Sirius Red staining). Scale bar: 100 μm
