Histopathology of Olfactory Mucosa in Kallmann's Syndrome
Annals of Otology, Rhinology & Laryngology, 1993Olfactory mucosa was harvested by intranasal biopsy from a man with Kallmann's syndrome in whom the absence of the olfactory bulbs was documented by magnetic resonance imaging. On electron microscopic examination, several pathologic changes were evident in the olfactory mucosa.

Immunohistopathology of variations of human olfactory mucosa
European Archives of Oto-Rhino-Laryngology, 1991The characteristics of the human olfactory mucosa were studied immunohistologically. Regular, zonal distribution of the supporting cells, multilayered olfactory receptor cells and basal cells was commonly found in the olfactory mucosa of the human fetus. In contrast, most of the olfactory mucosa in the adult varied to some extent.

Carnosine-like Immunoreactivity in Human Olfactory Mucosa
Acta Oto-Laryngologica, 1990By means of immunohistochemical techniques it is demonstrated for the first time ever that carnosine (beta-alanyl-L-histidine)-like immunoreactivity (LI) is localized in the olfactory receptor neuron in human olfactory mucosa. Carnosine-LI was found in all regions of the receptor cells, i.e. in dendrites, olfactory vesicles, soma and axons.

Olfactory Evoked Potentials Produced by Electrical Stimulation of the Olfactory Mucosa
Auris Nasus Larynx, 1996We stimulated the olfactory mucosa electrically and elicited evoked potentials in rabbits. A bipolar stimulating electrode was placed on the olfactory region of the nasal mucosa via an anterior naris non-invasively. Evoked potentials were detected from the surface of a head.

AbstractOlfactory ensheathing cells (OEC) have the ability to promote regeneration in the nervous system. Hence, they hold promise for cell therapy. Most of the experimental studies have investigated the role of OECs taken from olfactory bulb (OB). However, for a clinical human application, olfactory mucosa (OM) seems to be the only acceptable source ...

Immunohistochemical Studies of Olfactory Mucosa in Patients with Olfactory Disturbances
American Journal of Rhinology, 1989In order to examine the functional morphology of the human olfactory mucosa when olfaction is disturbed, immunohistochemical methods have been applied to mucosal biopsies. In the group of patients examined anosmia was due to bilateral choanal atresia, to chronic sinusitis, to the common cold (viral infection), and to head trauma.

The Olfactory Mucosa of Vertebrates
1971The vertebrate olfactory mucosa is that part of the lining membrane of the nasal cavities that contains olfactory receptor neurons. It is structurally different from the surrounding respiratory mucosa in many important respects, such as, a) the presence of Bowman’s glands, b) a characteristic yellow to brown color due to a pigment, c) and cilia not ...

Nonneoplastic Lesions of the Olfactory Mucosa
1996In recent years there has been a considerable increase in the number of reports on the histopathology of nasal olfactory mucosal responses to inhaled and parenterally administered chemicals (Bogdanffy 1990; Doty et al. 1991; Gaskell 1990; Mery et al. 1994a; Morgan and Monticello 1989).

Olfactory mucosa, aluminosilicates and Alzheimer's disease
Neurobiology of Aging, 1986Abstract Age-related degenerative changes in mucosal epithelium may result in decreased barrier function. This change may predispose the adjacent brain areas to invasion by organisms and toxins leading to regional tissue damage as seen in Alzheimer's disease (AD). Age-related decrease in nasal mucosal barrier function, however, would explain some but
