Heightened airway reactivity is a cardinal feature of asthma and correlates with many clinical features of the illness, such as the acute response to bronchodilator drugs, the magnitude of diurnal fluctuations in lung function, and the amount of therapy required to control symptoms. Data have accumulated indicating that a reduction in airway reactivity can decrease asthma morbidity, and many ad...
The mechanism of hyper-reactivity of the Dextrostix system when contaminated with alcoholic skin cleaning agents was investigated. When sodium fluoride was supplied to block glucose oxidase activity and hydrogen peroxide was exogenously provided benzidine peroxidation could be preferentially studied. Benzidine hydrochloride was the most likely site of the hyper-reaction.
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, ...
This study presents a comprehensive cellular atlas describing the ongoing pulmonary immune responses in early stages of diffuse alveolar damage. work indicates vital role hyper-inflammatory fibroblast subset around bronchus, mediating neutrophil infiltration through secreting soluble signaling mediators, thus boosting neutrophilic airway inflammation.
The purpose of this study was to evaluate whether nedocromil sodium benefits urban asthmatic children showing seasonal bronchial hyper-reactivity to ultrasonic nebulization of distilled water (UNDW). A prospective, randomized, placebo-controlled, parallel-group, double-blind study was carried out at the outpatient pulmonology service at a tertiary-care teaching hospital. Twelve children living ...
BACKGROUND Relationship between recurrent wheeze and airway function and inflammation in preschool children is not fully known. OBJECTIVE To investigate the relationship between recurrent wheeze and airway inflammation, lung function, airway hyper-reactivity (AHR) and atopy in preschool children. DESIGN Observational study, comparing forced expiratory volume in 1 s (FEV1), forced vital capa...
