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. The tissues were examined by both electron and

The nasal mucosa and outcomes of dacryocystorhinostomy
Arkhiv patologii, 2019To investigate the impact of the nasal mucosa on the outcomes of dacryocystorhinostomy on the basis of morphologic findings.The investigation enrolled 73 patients who had undergone endonasal endoscopic dacryocystorhinostomy. Nasal mucosal biopsies were intraoperatively taken from all the patients.

Atraumatic Biopsy of Nasal Mucosa
Archives of Otolaryngology - Head and Neck Surgery, 1969AN UNDERSTANDING of the cellular events that occur in the nose during the course of virus infections may be of importance if we are to make progress in developing satisfactory measures of preventing or treating common colds and related problems. One of the deficiencies in our knowledge in the past has been insufficient information about the location ...

Autonomic Innervation of the Nasal Mucosa
ORL, 2010The 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.

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

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.

Metabolism of Dopamine by the Nasal Mucosa
Journal of Pharmaceutical Sciences, 2006The nasal route of administration offers several advantages over oral and intravenous administration, including the ability to avoid hepatic first pass metabolism. Dopamine deficiency has been associated with several neurological disorders; it has been shown to have good systemic bioavailability and significant uptake into the CNS following intranasal ...

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.

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.
