Abstract: The purpose of the present study was to evaluate the change in the sizes of the gland following tracheoplasty and bronchoplasty, as well as to investigate the effect of steroid therapy on changes in the size of the bronchial gland following bronchoplasty. The total number of the glands, the mean bronchial gland area (MGA), and the ratio of the total gland area to the bronchial wall area (G/W) were measured in 70 dogs after tracheoplasty and left upper sleeve lobectomy of the lung. Nine dogs were used as a control. The results are as follows: 1) The mean gland area (MGA) and the G/W increased in both tracheoplasty and bronchoplasty groups, however the number of the bronchial gland has not increased. As a significant change in the bronchial gland following the plastic operations, hypertrophy of the bronchial gland develops. 2) In the tracheoplasty group, the MGA and the G/W much more increased at a resection of 14 tracheal cartilaginous rings than at that of 3 and 8. 3) In bronchoplasty group, the MGA and the G/W increased on day 7 than on day 21 and in the steroiduntreated group than steroid-treated group. It is concluded that tracheobronchial plastic operation enables the size of the bronchial glands to enlarge, and the enlarged bronchial glands grately responded to corticosteroid.
