(20) Peak uptake values were found 5 min after Adriamycin administration, and the amounts of Adriamycin in normal and carcinogen-altered bronchi were found to be similar.
Tracheobronchial
Definition:
(a.) Pertaining both to the tracheal and bronchial tubes, or to their junction; -- said of the syrinx of certain birds.
Example Sentences:
(1) Anhidrotic ectodermal dysplasia is characterized by an absence of seromucous glands in the oropharynx and tracheobronchial tree, making children with this disease prone to viral and bacterial respiratory infections.
(2) Findings for 56 patients show the largest normal mediastinal nodes to be in the subcarinal and right tracheobronchial regions.
(3) Patients with malignant disease are known to have an increased incidence of multinucleation in their tracheobronchial ciliated epithelial cells as compared with controls matched by age, sex and smoking habit.
(4) It imitates the conventional percussion massage of the thorax by introducing high-frequency gas oscillations (300 impulses per minute) into the tracheobronchial system.
(5) The effect of manual percussion of the thorax in nine patients with stable chronic airflow obstruction and excessive tracheobronchial secretion has been studied.
(6) Mean tracheobronchial mucociliary clearance was depressed after administration of both beta blocking drugs, although the reduction was significant (p less than 0.05) only when propranolol was compared with placebo.
(7) We conclude that the characteristics of the epithelial lining of the mammalian tracheobronchial airway tree are very species-specific.
(8) The inoculated metastases do not deteriorate the prognosis of the bronchogenic cancer, if the mediastinoscopy is strictly limited to the paratracheal and tracheobronchial lymphnodes.
(9) These results indicate that human tracheobronchial apomucins consist of a family of different proteins.
(10) We report three patients who had small caliber feeding tubes passed through the tracheobronchial tree perforating into the pleural space.
