Some Factors Concerning the Distribution of Bronchial Glands

It is well known that the secretion from bronchial glands play an important role to make the airway clean up against sticky bronchial secret. The aim of the present study was to evaluate the relationship between the functional modality of bronchial glands and occurrence of postoperative pulmonary complication due to difficulty of expectoration. However, the noteworthy development of bronchial glands was proved histologically with a distribution index (DI) in each circumstances of either the elderly more than 40 of age or existing inflammation of bronchial trees. Based on histochemical examination by means of PAS stain, the almost same attitudes in regard to magnitude of secretion were not necessarily documented even among bronchial glands with marked development. It was of note that the intimate correlation between secretory behavior of bronchial glands and development of bronchial glands was not certified in the series of this study and that secretory function of bronchial glands did not compatible with pronounced distribution and marked development of them. As a result of this study, the preventive role of bronchial glands from occurrence of postoperative pulmonary complication has not been substantiated by morphological and biochemical study
