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...
متن کاملUltrastructural immunocytochemical localisation of lysozyme in human bronchial glands.
An immunocytochemical unlabelled antibody method using rabbit antihuman lysozyme, antirabbit immunoglobulin, and soluble rabbit antihorseradish peroxidase/horseradish peroxidase complexes was used to study the fine structural distribution of lysozyme in human bronchial glands. None was identified in mucous cells but there was heavy staining of the serous cell granules. The serous cell granules ...
متن کاملIncreased myoepithelial cells of bronchial submucosal glands in fatal asthma.
BACKGROUND Fatal asthma is characterised by enlargement of bronchial mucous glands and tenacious plugs of mucus in the airway lumen. Myoepithelial cells, located within the mucous glands, contain contractile proteins which provide structural support to mucous cells and actively facilitate glandular secretion. OBJECTIVES To determine if myoepithelial cells are increased in the bronchial submuc...
متن کاملDistribution of acid mucus in the bronchial mucous glands.
The percentage area of the bronchial glands taking up the Alcian blue (pH 2-6) stain for acid mucin was obtained from sections from the trachea and from each generation down the inferior lingular axial bronchial pathway in five non-smokers and five cigarette smokers. The mean percentage value for the smokers (59-5%) was significantly less than for the non-smokers (74-4%). The percentage increas...
متن کاملUltrastructural localisation of lactoferrin and glycoprotein in human bronchial glands.
The distribution of lactoferrin and glycoprotein in human bronchial glands has been studied by electron microscopy using an immunoperoxidase method to stain the former and a periodic acid-chromic acid-silver methenamine sequence for the latter, each applied to ultrathin Epon sections. The distribution of lactoferrin corresponds to that of lysozyme. Lactoferrin and lysozyme are both confined to ...
