The olfactory mucosa, first actor of olfactory detection, is sensitive to glucocorticoid hormone
European Journal of Neuroscience, 2020The olfactory mucosa (OM) is the primary site of odorant detection, and its axonal projections relay information to brain structures for signal processing.

Olfactory mucosa/air partitioning of odorants
Brain Research, 1987The present study evaluates the contribution of the receptor cell compartment to the total mucosal odorant uptake. Using radioactive odorants, partition coefficients for normal bullfrog olfactory mucosa were compared to the partition coefficients from mucosa in which the receptor cells had been removed by cutting one of the olfactory nerves and ...

Cell dynamics in the olfactory mucosa
Tissue and Cell, 1973Abstract By means of ultrastructural and autoradiographic observations from the olfactory mucosa of frog, it has been shown that olfactory receptor neurons as well as supporting cells are continuously replaced during the adult life of the animal. The severing of the olfactory nerve in adult frogs results in rapid degeneration of all mature olfactory ...

The Ultrastructure of the Human Olfactory Mucosa [PDF]
, 1991 The purpose of this Chapter is to present a detailed description of the ultrastructure of the human olfactory mucosa. To this end, the Chapter is divided into four major sections which describe the biopsy technique; the ultrastructure of the normal olfactory mucosa in humans; the microvillar cell, and histopathologic changes of the olfactory mucosa in ...

Immunohistochemical Studies of Olfactory Mucosa in Patients with Olfactory Disturbances [PDF]
American Journal of Rhinology, 1989 In 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.

Mineralocorticoid Receptors in the Mammalian Olfactory Mucosa
Annals of Otology, Rhinology & Laryngology, 1999Mineralocorticoid hormones regulate secretion and absorption in a wide variety of epithelial tissues, although specific mechanisms in the olfactory mucosa are currently unknown. Utilizing reverse transcription—polymerase chain reaction (RT-PCR) analysis, we have demonstrated the expression of mineralocorticoid (type I) receptor messenger RNA in the ...

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.

Histochemical study of the olfactory mucosae of the horse
Acta Histochemica, 2016The olfactory mucosae of the horse were examined by using histology and lectin histochemistry to characterize the carbohydrate sugar residues therein. Histological findings revealed that olfactory epithelium (OE) consisted of both olfactory marker protein (OMP)- and protein gene product (PGP) 9.5-positive receptor cells, supporting cells and basal ...

The fine structure of the olfactory mucosa in man
Journal of Neurocytology, 1982This report gives a detailed description of the fine structure of the olfactory mucosa in man. Using a special biopsy instrument and technique, fresh biopsies of olfactory epithelium were taken under local anaesthesia from eight normal volunteers.
