Compounds of vanadium are known to cause bronchiolar
constriction, shortness of breath, conjunctiva irritation.
The genesis of the pulmonary tree and its branches--the mainstem, lobar, segmental and bronchiolar
airways--are defined by periods of lung development.
The major pathophysiologic changes in emphysema include chronic infection, excess mucous and inflammatory edema, entrapment of air in the alveoli and bronchiolar
obstruction increasing airway resistance.
In the lungs, reduced chloride secretion reduces the salt and water content of bronchiolar
mucus and periciliary liquid.
Peripheral increase in vascular resistance can be caused by underlying lung consolidation, atelectasis, or peripheral bronchiolar
Organizing pneumonia is diagnosed by its histopathologic pattern of fibroblastic plugs within alveolar ducts and inflammatory changes in the surrounding alveoli with varied bronchiolar
We move silently and cleanly about our towns or countryside at almost no risk to anyone else, and (this puts us even more on the side of the angels) we leave the air cleaner than we find it, thanks to the trapping of airborne particulate debris by the mucous sheet covering our bronchial and bronchiolar
The imidazolines have a lesser myocardial and bronchiolar
effect, whereas the amines produce more rapid tachyphylaxis and are less toxic to the nasal cilia.
Bronchoalveolar lung carcinoma spreads along the alveoli and bronchiolar
surfaces, making it nearly impossible to resect.
The immunohistochemical study demonstrated morbilliviral antigen in bronchiolar
epithelium, type 2 pneumocytes, and multinucleate (syncytial) cells from lung (Figure 1).
CCSP mRNA was significantly more abundant in distal bronchiolar
airways (generations 8-10) (Figure 1B) at GD150 (p = 0.
Thyroid transcription factor 1 (TTF-1), a nuclear transcription factor that is expressed in the developing forebrain, thyroid epithelium, and fetal lung epithelial cells, is expressed in normal adult bronchiolar
and alveolar epithelium as well as many pulmonary neoplasms, including small cell carcinomas (11) and adenocarcinomas.
