Cytokines and Bronchial Hyperreactivity
1990Cytokines and interleukins are a potent group of molecules that is primarily involved in maintaining homeostasis. These molecules regulate the growth and function of many cells of the immune system including eosinophils, mast cells/basophils and others.

Bronchial hyperreactivity revisited.
Annals of allergy, asthma & immunology : official publication of the American College of Allergy, Asthma, & Immunology, 1995The purpose of this article is to review bronchial reactivity: how it is detected, what are the clinical and pathologic correlates and what treatment modulates it. Is it a good diagnostic test for a disease such as asthma? Is it a reasonable parameter to follow in assessing disease severity and response to treatment?Recent studies on human subjects in ...

[Bronchial asthma and bronchial hyperreactivity].
Monatsschrift Kinderheilkunde : Organ der Deutschen Gesellschaft fur Kinderheilkunde, 1990Bronchial hyperreactivity to allergens and non-allergic stimuli is a feature of most patients with asthma as measured by the response to inhalants as pharmacological agents and physical stimuli. In contrast to adults there is an obvious relation of asthmatic episodes to allergen exposure in childhood.

[Bronchial hyperreactivity: neurogenic factors].
Revue des maladies respiratoires, 1994Over the last fifty years, the role of neurogenic factors in asthma and bronchial hyperreactivity has been intensively investigated. The roles of the cholinergic and adrenergic nervous systems have been clarified and several sub-types of muscarinic receptors identified.

[Bronchial hyperreactivity in infancy].
Anales espanoles de pediatria, 1993Airway responsiveness may be defined as the case with which airways narrow upon exposure to physical and chemical stimuli and drugs. Bronchial hyperresponsiveness reflects an excessive bronchoconstricting response to these stimuli. Although in part it may be genetically mediated, a number of environmental factors (allergens, viruses and contaminants ...

Experimental induced bronchial hyperreactivity.
European journal of respiratory diseases. Supplement, 1981Bronchial hyperreactivity can be influenced by antigen inhalation as well as by infections which affect the bronchial tree. Bronchial hyperreactivity characterizes the obstructive airway diseases. In order to study this problem, we have performed in our laboratory a series of experiments concerning this problem.

[Bronchial hyperreactivity in athletes].
Nordisk medicin, 1994Elite athletics, particularly endurance sports, are characterised by a high prevalence of bronchial hyperresponsiveness (BHR) and exercise-induced asthma (EIA). Findings in several studies suggest short-term high intensity physical activity to cause a transient increase in BHR.

Factors in Bronchial Hyperreactivity
1987In patients with asthma, bronchospasm can be provoked by the inhalation of a wide variety of different agents [11]. These agents, which are sometimes called inciters of bronchospasm [31], include analogues of the parasympathetic neurotransmitter acetylcholine, chemical mediators of inflammation such as histamine, serotonin, prostaglandins, and ...

Virus-Induced Bronchial Hyperreactivity
1996Exacerbations of asthma and chronic bronchitis are commonly due to viral infections of the airways [1–11]. The association of viral infection with asthma exacerbation is most striking in children, in whom at least 30–40% [12–14] and perhaps as many as 75% of exacerbations [15] of asthma are caused by viral infections.
