Figure 2: Panel-A indicates H and E stain whereas panel-B showing masson's trichrome stains of rat lungs (magnification ×100). In panel A, Groups I: Normal control animals, Groups II: Sephadex control shows swollen cuboidal epithelial cells of the terminal bronchiole and infl ammatory cell infi ltration, Groups III: Rosiglitazone showed a number of small tubular structures of bronchiolar epithelial cells and some foci of small intraalveolar fi brosis and Groups IV: Dexamethasone treated group did not show perivasculitis and peri-bronchial degradation. In panel B, collagen stain showed light green. Groups I: Normal control has normal architecture, Groups II: Sephadex treated animal showed dense mature collagen, peribronchial/perivascular cellular infiltration of eosinophils and mononuclear cells; Groups III: Rosiglitazone treated animal has mild cellular infiltration and collagen deposition; Groups IV: Dexamethasone treated animal having no collagen deposition
