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 ...

Histopathological changes in nasal mucosa with nasal septum deviation
European Archives of Oto-Rhino-Laryngology, 2014Histopathological changes in septal and nasal mucosa of patients with nasal septum deviation are not well known. Biopsies of septal and lateral nasal mucosae from both sides of nose were obtained from 20 patients undergoing septoplasty and control group of 10 patients undergoing head and neck surgery.

Beta adrenoceptors in human nasal mucosa
The Journal of Laryngology & Otology, 1991AbstractThe significance of the beta adrenergic system in the nasal mucosa isunclear. The authors have used the technique of autoradiography to localize and classify beta adrenoceptors in human nasal mucosa. The receptors have been found to beexclusively of thebeta-2 subtype and the highest density is found in the glandularducts.

Parasympathetic Influence on the Nasal Mucosa
Acta Oto-Laryngologica, 1977The effect of graded parasympathetic nerve stimulation on the exchange and capacitance vessels of the nasal mucosa, as well as the secretory response, is reported. Possible postganglionic mediators of the vascular and secretory effects are discussed.

Archives of Otolaryngology - Head and Neck Surgery, 1935
The diverse and frequently extensive manipulations of the nasal mucous membranes involved in surgical procedure on the nose and paranasal sinuses have generally been initiated and governed by the final results obtained. Most of the literature on experimentation on animals also has been devoted to this end.

Sympathetic Influence on the Nasal Mucosa
Acta Oto-Laryngologica, 1977The tone of the resistance vessels determines the capillary flow and the tone of the capacitance vessels --the nasal patency. Lower impulse frequencies in the sympathetic nerves affect mainly the capacitance vessels, while higher frequencies affect both types of vessel.
