Uptake of Antibiotics by Nasal Mucosa

The Fungi Flora of Healthy Nasal Mucosa in Kerman, Iran

Introduction: Environmental fungi, molds and yeasts, can infest the nasal cavity through inhaled air. There is some evidence that they could be the main cause of Chronic Rhinosinusitis (CRS) but little is known about the normal fungal flora in the human nose. The objective of this study was to assess the normal fungal flora of the nasal mucus in adults in Kerman. Materials and Methods: We ...

Metabolism of tobacco-specific nitrosamines by cultured rat nasal mucosa.

The metabolism of two nasal carcinogens, N'-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), was investigated using cultured nasal septa of F344 rats. The explants were cultured with 14C-labeled N-nitrosamines, and unbound metabolites present in the medium were quantitated by high-performance liquid chromatography. The results indicated that the mucosa of the n...

Uptake and Transport Pathways for Ultrafine Nanoparticles (Quantum Dots) in the Nasal Mucosa

Comparison of Expression of Cytokeratin 7 on Epithelium of Nasal Polyps and Mucosa of Chronic Rhinosinusitis

Background and Objective: Nasal polyp is the most common benign mass of the nasal cavity and it is originated from nasal cavity or sinuses. Cytokeratins (CK) are intermediate filament proteins that provide mechanical support in epithelial cells. The purpose of this study was to compare the expression of cytokeratin 7 in epithelium of nasal polyps and nasal mucosa in chronic rhinosinusitis. Mate...
