airway remodelling is characterized by the thickening and reorganization of the airways seen in mustard  lung patients. mustard lung is the  general description  for  the  chronic obstructive  pulmonary  disease induced  by  sulfur  mustard(sm). pulmonary  disease was diagnosed as the most important  disorder in individuals that had been exposed to sulfur mustard. sulfur mustard is a chemical w...

Plastic bronchitis (PB) refers to the presence of inspissated Bronchial casts (BC) is uncommon in children.Our case presented with subcutaneous emphysema as the dominant manifestation and was suspected to have foreign body in airway, but bronchoscopy revealed a bronchial cast. Subcutaneous emphysema as the initial/sole manifestation of plastic bronchitis is very rare in children.

In asthmatic subjects there is a pronounced diurnal variation in bronchial responsiveness. If this phenomenon is due to variation in factors that control drug delivery, then it should be paralleled by a similar variation in competitive antagonist blockade. In order to study this possibility, we performed the methacholine challenge test and after 45 minutes, administered atropine by inhalat...

treacher collin’s syndrome (tcs) is a rare inherited condition characterized by bilateral and symmetric abnormalities of structures within the first and second bronchial arches. patients with tcs present a serious problem to anesthetists maintaining their airway as upper airway obstruction and difficult tracheal intubation due to severe facial deformity. because of retrognathia, airway manageme...

Rhesus monkeys with airway responses to aerosol challenge with Ascaris antigen constitute a primate model of inhalant asthma. Previous studies have shown that bronchial lavage cells from airway-reactive animals will release histamine or a slow-reactive substance of anaphylaxis after challenge with antigen. Because these bronchial lumen cells are the first cells in contact with inhaled antigen, ...

The bronchial vasculature is the systemic arterial blood supply to the lung. Although small relative to the pulmonary blood flow, the bronchial vasculature serves important functions and is modified in a variety of pulmonary and airway diseases. Congestion of the bronchial vasculature may narrow the airway lumen in inflammatory airway diseases, and formation of new bronchial vessels (angiogenes...

BACKGROUND Impaired epithelial barrier function renders the airway vulnerable to environmental triggers associated with the pathogenesis of bronchial asthma. We investigated the influence of protocadherin-1 (PCDH1), a susceptibility gene for bronchial hyperresponsiveness, on airway epithelial barrier function. METHODS We applied transepithelial electric resistance and dextran permeability tes...

Bronchial asthma is characterized by the bronchial hyperresponsiveness and airway obstruction related to airway smooth muscle contraction. Eosinophilic airway inflammation is involved in its pathogenesis. To reproduce the condition, various animal models have been prepared. However, there are many models that do not reflect the spontaneous history of bronchial asthma onset in humans due to the ...
