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.

MALIGNANT MELANOMA OF THE NASAL MUCOSA
Archives of Otolaryngology - Head and Neck Surgery, 1947IN THE study of oncology, melanomas, the group of tumors characterized by melanin-pigmented cells, form a distinctive class of neoplasms that present vexing problems of remarkable interest, with wide differences of opinion regarding their origin and nature. These tumors may be innocuous or malignant. The benign tumor is commonly called a nevus or mole.

Endothelin in Human Nasal Mucosa
American Journal of Respiratory Cell and Molecular Biology, 1993Abstract Endothelin (ET), a potent vasoconstrictor and bronchoconstrictor peptide synthesized by endothelial and epithelial cells, was examined for its potential functions in human inferior turbinate nasal mucosal tissue by four techniques: (1) immunoreactive ET was localized in the mucosa by immunohistochemistry; (2) receptors for ET

Mast cell quantitation in nasal polyps, sinus mucosa and nasal turbinate mucosa
The Journal of Laryngology & Otology, 1993The distribution and abundance of mast cells in nasal polyps, the maxillary sinus mucosa of patients with sinusitis and the turbinate mucosa of allergic rhinitis was microscopically examined using different methods of fixation. In the epithelium of the surface and the ducts of nasal polyps (n = 8), the mean number of mast cells was over 20,000 per mm3 ...

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.

Drug Metabolism in the Nasal Mucosa
Pharmaceutical Research, 1992Nasal delivery is a potential alternative for systemic availability of drugs restricted to intravenous administration, such as peptide and protein drugs. Although nasal delivery avoids the hepatic first-pass effect, the enzymatic barrier of the nasal mucosa creates a pseudo-first-pass effect.

Metastatic choriocarcinoma of the nasal mucosa
Journal of Surgical Oncology, 1977AbstractA patient with a chief complaint of epestaxis coughed persistently during her visit to the emergency room. Questioning revealed she also had vaginal bleeding and occasional bloody sputum. Gynecological examination, a Pap smear, and pathological evaluation showed choriocarcinoma. A chest X ray disclosed metastatic pulmonary choriocarcinoma.
