C, Collapsed bronchiolar epithelial lined alveoli (Lambertosis) can look concerning, but the relationship to the bronchiole confirms a benign metaplastic proliferation (hematoxylin-eosin, original magnifications X10 [A], X2 [B], and X20 [C]).
In Group II was observed an increased amount of the number and caliber of the bronchi and bronchioles (Figures 2D and 2E), decreased mesenchyme and the initial opening of the internal lumen of the bronchioles (Figure 2F).
8) Narrowing of the bronchioles is the main cause of reduced airflow through the lungs, and also contributes to air trapping during exhalation.
The study did not indicate whether asthma, which is the result of inflammation in the bronchioles of the lungs, also contributes to increased inflammation in the blood vessels.
In the control mice, influenza virus infection resulted in severe inflammation of the bronchioles and appeared to be flooded and surrounded with inflammatory cells.
Result: Structural changes were found in the experimental (5-fluorouracil) group compared to the controls, including abnormal alveolar duct, sac, and terminal bronchioles with emphysematous changes in most of the alveoli in addition to peribronchiolitis, perivasculitis, inflammatory cells infiltration and interstitial fibrosis.
The trachea bronchi and bronchioles of these animals were explored carefully for the presence of the adult lungworms.
First, nicotine seems to trigger the nervous system to cause contraction of the bronchi and bronchioles, the little tubes through which air should whistle happily on its way to the oxygenexchanging areas of the lung.

However, compared to other avian influenza viruses, the attachment to epithelial cells by H7N9 in the bronchioles and alveoli of the lung was more abundant and the viruses attached to a broader range of cell types.
Bacterial respiratory colonization and subsequent inflammation probably play an important role in dilating the bronchioles and causing bronchiectasis--which leads to more colonization.
Alveoli were packed with serosanguineous mass and bronchioles revealed degeneration in lining epithelial cells.
