Epithelial Damage of Nasal Mucosa in Nasal Allergy
Annals of Otology, Rhinology & Laryngology, 1998Epithelial alterations arising from moderate nasal allergy to house dust were examined and compared to findings in epithelia from nonallergic controls. Biopsy specimens were taken during natural allergen exposure from two different sites: 1) the anterior tip of the inferior turbinate and 2) 2 cm behind it.

Inflammatory cells in nasal mucosa and nasal polyps
Auris Nasus Larynx, 2000Since some controversy exists concerning the frequency of inflammatory cells in nasal polyps, we have compared the frequency of tissue inflammatory cells (lymphocytes, neutrophils, eosinophils and plasma cells) including 11 kinds of lymphocyte subsets in the same specimens of nasal mucosa and nasal polyps.Histopathological observations and flow ...

Cytological alterations of nasal mucosa after nasal packing
American Journal of Otolaryngology, 2014To assess the efficacy, tolerability and cytological alterations of nasal mucosa with various materials for nasal packing.One hundred and five patients, submitted to a nasal surgery and post-operative packing with four different materials (Clauden®, Merocel®, two-fingered glove pack with gauzes inside and Lyofoam™) were prospectively enrolled in the ...

Autonomic Innervation of the Nasal Mucosa
ORL, 1988The nasal passages play a crucial role in the protection and functioning of the lower airways. Consequently the nerve supply of the nasal mucosa is extensive, which is related to an immediate and adequate reaction upon a variety of external and internal stimuli.

Interaction of Cocaine With Nasal Mucosa
Archives of Otolaryngology - Head and Neck Surgery, 1991Canine nasal mucosa was studied in vitro to examine (1) the production of vasoconstriction by cocaine and, (2) the epithelial permeability of cocaine. Cocaine, by itself, failed to induce any contraction of the nasal blood vessels but did enhance contractions resulting from electrical stimulation or addition of norepinephrine.

Contact Endoscopy of the Nasal Mucosa
Acta Oto-Laryngologica, 1997The possibility of contact endoscopy in the nasal mucosa, using a contact microlaryngoscope is examined. With contact endoscopy it has been possible to visualize in vivo and in situ (60x, 150x) the superficial cell layers of the nasal epithelium, previously stained with methylene blue.

Effect of snuff on nasal mucosa
American Journal of Otolaryngology, 2005The inhalation of nasal snuff (powdered tobacco) is a common addiction in the Indian subcontinent. In the western world, there is a resurgence of interest in nasal snuff because it does have the morbidity associated with smoked tobacco. Very few studies have reported the long-term effects of snuff on nasal mucosa. The objective of the present study was

Nasal Mucosa in Pancreatic Cystic Fibrosis
Archives of Otolaryngology - Head and Neck Surgery, 1967UNDERSTANDING of the nasal respiratory changes in cystic fibrosis of the pancreas has developed slowly during the past 20 years. At present this area has received little attention and offers much information to the investigator. An attempt is made to compare the nasal polyps of cystic fibrosis patients to normal nasal respiratory mucosa using various ...

Fluorescein Flowmetry in Human Nasal Mucosa
Acta Oto-Laryngologica, 1986In sixteen patients a relative blood flow, expressed as an index, in the nasal mucosa was measured by fluorescein flowmetry (FF) using an endoscope technique. Duplicate determination showed slightly lower values in the second measurement performed 5 min after the first one.

Glutathione transferases in human nasal mucosa
Archives of Toxicology, 1989Glutathione transferase (GST) was investigated with 1-chloro-2,4-dinitrobenzene as substrate in tissues specimens of human nasal mucosa. The average +/- (SD) of GST activity in the cytosol was 76.8 +/- 21 nmol/min/mg with a range of 47-113. Using affinity chromatography and isoelectric focusing, the isozymes of GST from human nasal mucosa have been ...
