Evaluation of vascular endothelial growth factor A and endostatin levels in induced sputum and relationship to bronchial hyperreactivity in patients with seasonal allergic rhinitis

, 2013
Background: Studies about the pathogenesis of bronchial hyperreactivity (BHR) in patients with allergic rhinitis (AR) and its relationship with lower airway remodeling are extremely limited.

Epithelium-derived relaxing factor(s) and bronchial reactivity

, 1988
Damage to or dysfunction of respiratory epithelial cells may contribute to the etiology of bronchial hyperreactivity in asthma and airway infection. This brief overview summarizes the data, which suggest that release of relaxing factor(s) from epithelial

[Bronchial hyperreactivity].

Allergologia et immunopathologia, 1987
Bronchial hyperreactivity is a condition in which the airways show a much greater bronchoconstriction response to provocative stimuli than what is normal. The stimuli may be specific (different allergens) or non-specific (exercise, infection, cold, air, ozone, kerosene or a variety of inhalant irritants).

Dissociation between bronchial hyperreactivity in vivo and reduced β-adrenoceptor sensitivity in vitro in allergen-challenged guinea pigs

, 1994
In a recently developed guinea pig model of allergic asthma, we investigated the relationships between allergen-induced bronchial hyperreactivity in vivo, tracheal smooth muscle function in vitro, and the number of inflammatory cells in the ...

Effect of inhaled beclomethasone dipropionate on bronchial hyperreactivity in asthmatic children during maximal allergen exposure

, 1991
In this double blind study we evaluated the effect of a 2 months long treatment with inhaled beclomethasone dipropionate (300 micrograms/day) on methacholine responses in asthmatic children, during a period of maximal allergen exposure.

CONTRIBUTION OF A CHOLINERGIC REFLEX MECHANISM TO ALLERGEN-INDUCED BRONCHIAL HYPERREACTIVITY IN PERMANENTLY INSTRUMENTED, UNRESTRAINED GUINEA-PIGS

, 1995
1 In conscious, permanently instrumented, unrestrained, ovalbumin-sensitized guinea-pigs the development of allergen-induced bronchial hyperreactivity to histamine- and methacholine-inhalation was investigated after the early as well as after the late ...

Clinical Characteristics of Bronchial Asthmatics Who Showed Negative Conversion of Airway Hyperreactivity in the Methacholine Provocation Test [PDF]

, 2008
Background: Clinical characteristics of asthmatics undergoing negative conversion of bronchial hyperreactivity in the methacholine bronchial provocation test (M-test) were not completely evaluated yet. We investigated clinical characteristics of negative

CPAP increases bronchial reactivity in OSAS patients

European Respiratory Review, 2008
Continuous positive airways pressure (CPAP) is a well known and safe method of treatment patients with obstructive sleep apnoea syndrome (OSAS). The effects of CPAP administration on the upper respiratory tract are known. However its effects on the lower
