Immunopathology of mucous membranes and exocrine glands

EXOCRINE GLANDS OF Schwarziana quadripunctata

This article describes the location, anatomy, histology and ontogeny of adult Schwarziana quadripunctata exocrine glands. These glands appear either as individualized organs (salivary gland system and Dufour gland) or as epidermis differentiation (tegumentary glands). Variations in the occurrence and degree of development among colony components with regard to their degree of maturity are also ...

A common spectrum of polypeptides occurs in secretion granule membranes of different exocrine glands

A highly purified membrane preparation from rat parotid secretion granules has been used as a comparative probe to examine the extent of compositional overlap in granule membranes of three other exocrine secretory tissues--pancreatic, lacrimal, and submandibular--from several standpoints. First, indirect immunofluorescent studies using a polyclonal polyspecific anti-parotid granule membrane ant...

Oncocytes in human bronchial mucous glands.

Oncocytes were found in the bronchial glands of 30 of 33 lungs in which the left bronchial tree was examined. They were found with similar frequency in the main, upper and lower lobe bronchi. They were found more commonly with increasing age and were most frequent in the collecting duct of the bronchial glands. However, they were absent from the collecting duct in 14 cases. They were not increa...

Aquaporin water channels in exocrine glands.

Ashy dermatosis with involvement of mucous membranes*

Ashy dermatosis is a rare condition, of unknown aetiology, in which mucous membranes are typically spared. The authors report the case of a 57-year-old female with a history of asymptomatic gray-bluish macules located on the trunk and oral mucosa. There were no relief changes on examination. Skin biopsies from the oral mucosa and trunk were performed and both were compatible with ashy dermatosi...
