Recently, the evidence for platelet association with allergic diseases has been established by many researches. Activated platelets contribute to airway hyper reactivity, bronchoconstriction, airway inflammation and airway remodeling in asthmatic patients. We aimed to clarify platelet activation and key molecules on platelets, which are mainly associated with the mechanism underlying aspirin-ex...

Airways reactivity, hyper-reactivity, and hyper-responsiveness are terms used to describe airways for which there appears to be increased bronchial smooth muscle tone or responsiveness. Some patients with cystic fibrosis (CF) have concomitant asthma causing airway hyperresponsiveness as manifested by recurrent acute symptoms of dyspnea that is impressively responsive to an inhaled beta 2 agonis...

Background The concept of Atopic march was developed to study the progress of Atopic Dermatitis to Allergic Rhinitis to Asthma. Epidemiologic studies have constantly demonstrated strong associations between Rhinitis and Asthma. Bronchial hyper-reactivity is an important component in the definition of Asthma. Many patients with Allergic Rhinitis have lower Airway hyperreactivity or bronchial hyp...

Objective: To evaluate and compare the protective effects of salbutamol and montelukast in amelioration of insulin induced airway hyper-reactivity on isolated tracheal smooth muscle of guinea pig in vitro. Study Design: Laboratory based randomized control trials (Experimental study). Place and Duration of Study: Pharmacology Department and Centre for Research in Experimental and Applied Medicin...

BACKGROUND The current paradigm describing asthma pathogenesis recognizes the central role of abnormal epithelial function in the generation and maintenance of the disease. However, the mechanisms responsible for the initiation of airway remodeling, which contributes to decreased lung function, remain elusive. Therefore, we aimed to determine the role of altered pulmonary gene expression in dis...

Asthma and other respiratory diseases have increased in the last years among Venezuelan children from helminthic endemic areas where the infection by Ascaris lumbricoides has been associated to bronchial airway inflammation in parasitized individuals. The aim of this work was to investigate the possible associations between the development of bronchial hyper reactivity and the immune response a...

This paper reviews the basis for bronchoalveolar lavage and lung function tests for the diagnosis of inflammatory airway disease (IAD)—defined as cough, airway mucus, and/or exercise intolerance. It is important to realize that these signs, no matter how subtle, may indicate the presence of lower airway inflammation, airway obstruction, and airway hyper-reactivity, which are inextricably linked...

Release of human lung mast cell tryptase may be important in the pathophysiology of asthma. We examined the effect of the reversible, nonelectrophilic tryptase inhibitor MOL 6131 on airway inflammation and hyper-reactivity in a murine model of asthma. MOL 6131 is a potent selective nonpeptide inhibitor of human lung mast cell tryptase based upon a beta-strand template (K(i) = 45 nM) that does n...

the relationship between mycoplasma pneumoniae (mp) infection and asthma has rarely been explored through examination of airway reactivity. the aim of this study was to determine airway reactivity changes after mp infection in children. first, 106 children were divided into four groups according to the existence of mp infection and/or asthma. then children with only mp belonged to the mp group;...
