Figure 1.

Representative photomicrographs showing haematoxylin and eosin (H&E) stained lung sections from a bleomycin-induced C57 mouse model of pulmonary fibrosis: (a–d) day 7; (e–h) day 14; and (i–l) day 28 following initiation of prednisolone acetate/dermatan sulphate treatment. Four study groups included controls treated with saline only (a, e, i), bleomycin-induced fibrosis model (b, f, j), bleomycin-induced fibrosis treated with 6.67 mg/kg prednisolone acetate (c, g, k) and bleomycin-induced fibrosis treated with 5.3 mg/kg dermatan sulphate (d, h, l).
