Nose, Olfactory epithelium - Inflammation, Suppurative, and Nose, Respiratory epithelium - Inflammation, Suppurative in a male F344/N rat from a chronic study. In addition to the suppurative reaction in the nasal cavity, the nasopharyngeal duct is also affected.

Nose, Olfactory epithelium - Inflammation, Suppurative in a male F344/N rat from a chronic study. A pronounced epithelial proliferative reaction is present secondary to the suppurative inflammation.
