Nasal glands in nasal allergy.

The entire nasal mucosa from a patient with nasal allergy and hay fever was studied by the whole mount method, and the density of submucous glands was determined. Their density was essentially greater than in normal noses in all parts of the nose, especially on the conchae. This finding indicates that new-abnormal-glands form in the course of the disease, glands which also differ morphologically from the normally occurring glands. As this greatly increases the secretory capacity of the mucous membrane, there is a patho-anatomical basis for assuming that the nasal secretion in allergy is formed exclusively by the existing glands. Other sources of nasal secretion, such as exudation and transudation under normal conditions and in allergy, as well as the mode and causes of gland formation, are discussed.
