From: Similar matrix alterations in alveolar and small airway walls of COPD patients
Decreased elastin in alveolar and small airway walls of COPD patients. Photomicrographs of elastin 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 elastin 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.
