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 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 کاملMUC5B and MUC7 are differentially expressed in mucous and serous cells of submucosal glands in human bronchial airways.
Mucins are high molecular-weight glycoproteins involved in the protection and lubrication of respiratory, gastrointestinal, and reproductive tracts. Hypersecretory diseases such as cystic fibrosis (CF), chronic bronchitis, and asthma result in dysregulated levels of mucin production stemming from increased abundance of mucin-secreting cell types in the surface airway epithelium and submucosal g...
متن کاملAcomparison of changes in the mucous glands and goblet cells of nasal, sinus, and bronchial mucosa.
as measures of hypertrophy. In 14 of these cases the relationship between goblet cell hyperplasia in the sinus mucosa and the presence of chronic bronchitis was investigated by comparing the proportion of goblet cells with the corresponding Reid index. No significant correlation was found between nasal and bronchial mucous gland size, and no association was demonstrated between the proportion o...
متن کامل[Electron microscope studies of human tracheal glands, with special reference to oncocytes and oncocytic cells].
Twenty-nine cases of human tracheal glands were studied in electron microscopy . The materials used in this study were taken from patients whose ages ranged from 1 to 90 years old of both sexes. The tracheal glands were composed of occasionally branched tubulo-alveolar glands consisting of the duct and the terminal portion of both mucous and serous type , and furthermore, smoothmuscle type myoe...
