Quantitative computerized analysis of PPARγ immunostained epithelium in sections from biopsies of nasal mucosa and nasal polyps from 5 patients, and 6 patients with fluticasone treatment. The area of those parts of the epithelium that were immunostained by PPARγ antibodies was measured in relation to the length of the epithelium. Bold lines represent the median values. * P < 0.05.
