Background: Flexible bronchoscopy enables visualization of the respiratoryairway mucosa from the oropharynx to third generation branching of the tracheobronchial tree.

In contrast, no relationship between upper respiratoryairway diseases and asthma and allergic rhinitis was observed, with PR of 0.71 (0.35-1.48) and 1.30 (0.87-1.95), respectively.

Treatment of the animals with cyclosporine blunted the inflammatory response and prolonged recombinant gene expression in both conducting and respiratoryairways.
