bronchi
On the basis of an analysis of the experimental data and general physical considerations it is shown that under conditions of forced expiration during the development of stenosis the lumen of the large bronchi may deviate from the equilibrium value.
      
The forced expiration time constant at the level of small bronchi is higher than that for medium bronchi.
      
The diagnosis of a critical airway obstruction reaching from the sublaryngeal region to the main bronchi caused by relapsing polychondritis was made and the patient received corticosteroids and dapsone.
      
To stabilize the airways, a bifurcated stent (dynamic stent?) was implanted into the trachea and the proximal parts of the main bronchi; furthermore a Palmaz stent was placed into left main bronchus.
      
The forced expiration technique is another method of self-treatment, employing expiratory techniques to blow secretions out of the bronchi.
      
the portions of the trachea and bronchi with labia and membranes) as a single membrane.
      
The regulating effects of protein kinase C on the tone of guinea-pig trachea and human lobus bronchi
      
The regulating effects of protein kinase C (PKC) on the tone of guinea-pig trachea and human lobus bronchi were investigated by measuring the tone of isolated tracheal and bronchial strips.
      
The effects of PKC on the tone of guinea-pig tracheal and human lobus bronchi were observed and compared.
      
Human bronchi smooth muscle cells were cultured with CSE at the different concentrations.
      
The results showed the expression of both Hsp70 mRNA and Hsp70 was decreased conformably in human bronchi smooth muscle cells treated with CSE at certain concentrationin vitro.
      
The involved lobular bronchi and part of main bronchi were resected and single-layer continuous suture with 5-0 Prolene was used for suturing of the carina of the reconstructed segmental bronchi to form lobular bronchi.
      
Then, single-layer continuous suture with 4-0 Prolene was employed to anastomose the "lobular bronchi" with main bronchi.
      
The URT morphological model consists of the extrathoracic (ET) region (nasal, oral, pharyngeal, and laryngeal passages) and upper airways (trachea and main bronchi) of the lung.
      
The computer reconstruction of the trachea and main bronchi was based on data from the literature (cited herein).
      
The URT model includes airways of the head (nasal and oral), throat (pharyngeal and laryngeal), and lungs (trachea and main bronchi).
      
Studies from our laboratory have shown that allergen challenge of passively sensitized human bronchi causes a β-adrenoceptor dysfunction as a result of reduced activity of the receptor-coupled Gs protein.
      
However, 30 % of lung cancers cause obstruction in the trachea and main bronchi.
      
In association with perforating or blunt trauma, isolated injuries of the trachea and the bronchi are rarely seen.
      
Five to eight grams of this substance were sufficient to produce a satisfactory contrast-positive layer coating on the surface of trachea and bronchi as far as third order bronchi.
