Figure 2

Deposition of collagen in the alveolar walls in addition to small airway walls. Photomicrographs of collagen in alveolar walls of one representative control subject (A), GOLD II patient (B), GOLD IV patient (C) and small airway walls of a control (D), a GOLD II patient (E) and a GOLD IV patient (F). Quantitative measured collagen content in alveolar walls (G) and small airway walls (H). Data were analysed using ANCOVA and results are expressed as means + SD; *P < 0.05 compared to control, **P < 0.05 compared to control and GOLD II.
