2. Fig 1
Photomicrographs showing the bronchial mucosa from a nonsmoker (A), a smoker with normal lung function (B), a patient with mild/moderate COPD (C), and a subject with severe COPD (D) immunostained for identification of NT+ cells (arrows) in the submucosa. Results are representative of those from 11 nonsmokers, 13 smokers with normal lung function, 14 patients with mild/moderate COPD, and 13 patients with severe COPD. E, Epithelium.

Photomicrographs showing the bronchial mucosa from a nonsmoker (A), a smoker with normal lung function (B), a patient with mild/moderate COPD (C), and a subject with severe COPD (D) immunostained for identification of iNOS+ cells (arrows) in the submucosa. Results are representative of those from 11 nonsmokers, 13 smokers, 14 patients with mild/moderate COPD, and 13 patients with severe COPD. E, Epithelium.

Photomicrographs showing the bronchial mucosa from a nonsmoker (A), a smoker with normal lung function (B), a patient with mild/moderate COPD (C), and a subject with severe COPD (D) immunostained for identification of eNOS+ cells (arrows) in the submucosa. Results are representative of those from 11 nonsmokers, 13 smokers with normal lung function, 14 patients with mild/moderate COPD, and 13 patients with severe COPD. E, Epithelium.

Photomicrographs showing the bronchial mucosa from a nonsmoker (A), a smoker with normal lung function (B), a patient with mild/moderate COPD (C), and a subject with severe COPD (D) immunostained for identification of MPO+ cells (arrows) in the submucosa. Results are representative of those from 11 nonsmokers, 13 smokers with normal lung function, 14 patients with mild/moderate COPD, and 13 patients with severe COPD. E, Epithelium.

6. Fig 5
Regression analysis between postbronchodilator FEV1 % predicted (A and C), FEV1/FVC % (B and D), and numbers of NT+ (A and B) and MPO+ (C and D) cells in the submucosa of all patients with COPD. Correlation coefficients were calculated by using the Spearman rank method.
