2 Fig. 1 Schematic chart of the study design. After 6 weeks of fluticasone propionate or placebo treatment, an allergen challenge was performed. Each patient underwent 5 nasal biopsies: at baseline; after 4 weeks of treatment (2 weeks before allergen challenge); 1 hour after challenge with grass pollen; 24 hours after allergen challenge; and 1 week after allergen challenge.
