Sections show staining in nasal antral mucosa (A, B), nasal polyps (C), airway sub-mucosal glands (D, E), epithelial cells of the airways (F) and negative staining in peripheral lung (G). Staining was also found in parotid (H), submandibular (I) and sub-lingual (J) glands and minor glands from the tongue (K) and tonsil (L).
