Fig 1 Examples of the immunohistochemical stainings. The same biopsy section is shown for the immunohistochemical staining for α-SM-actin (A), myosin (B), desmin (C), vimentin (D), calponin (E), MLCK (F), type III collagen (G), fibronectin (H), and elastin (I). Original magnification ×200 for all graphs.

Fig 2 Associations between smooth muscle markers and lung function parameters. The mean density of desmin (r = 0.61; P = .02) (A) and MLCK (r = 0.55; P = .05) (B) in relationship with FEV1% of predicted; desmin (r = −0.56; P = .04) (C) and actin (r = −0.62; P = .02) (D) in relationship with PC20 methacholine; and desmin (r = −0.60; P = .03) (E) and MLCK (r = −0.60; P = .03) (F) in relationship with the change in RrsInsp by deep breath. DI, Deep inspiration; SM, smooth muscle.
