Effect of a Single Dose Montelukast Sodium on Methacholine Chloride PC20 [PDF]

open access: yesCanadian Respiratory Journal, 2005
BACKGROUND: It is currently recommended that leukotriene modifiers (receptor antagonists and synthesis inhibitors) be withheld for a minimum of 24 h before direct bronchoprovocation testing, but there is little evidence to support this recommendation.

Etiologies and Treatment Outcomes of Chronic Cough Diagnosed with a Pathophysiological Diagnostic Procedure: A Single-center Retrospective Observational Cohort Study [PDF]

open access: yesThoracic Research and Practice
OBJECTIVE: We developed a pathophysiological diagnostic procedure to identify etiologies of chronic cough (CC) like cough variant asthma (CVA), atopic cough (AC), cough predominant asthma, sinobronchial syndrome (SBS), and mucoid impaction of small ...

Comparison of nasal responsiveness to histamine, methacholine and phentolamine in allergic rhinitis patients and controls [PDF]

open access: yes, 1987
In a selected group of rhinitis patients with an IgE‐mediated allergy to house dust mites the nasal response to insufflation of histamine chloride, methacholine and phentolamine was demonstrated to be higher than in a control group. With the methods used

Smooth Muscle Hypocontractility and Airway Normoresponsiveness in a Mouse Model of Pulmonary Allergic Inflammation

open access: yesFrontiers in Physiology, 2021
The contractility of airway smooth muscle (ASM) is labile. Although this feature can greatly modulate the degree of airway responsiveness in vivo, the extent by which ASM’s contractility is affected by pulmonary allergic inflammation has never been ...

Comparison of arterial storage conditions for delayed arterial ring testing

open access: yesJVS - Vascular Science, 2023
Objective: Arterial ring testing is the gold standard for measuring arterial function. Increased arterial tone through arterial contraction and impaired endothelial relaxation (endothelial dysfunction) are key metrics of impaired arterial health in ...

Bronchodilator Response in Patients with Persistent Allergic Asthma Could Not Predict Airway Hyperresponsiveness [PDF]

open access: yes, 2007
Anticholinergics, or specific antimuscarinic agents, by inhibition of muscarinic receptors cause bronchodilatation, which might correlate with activation of these receptors by the muscarinic agonist methacholine.

Pulmonary Function Tests in Thunderstorm-associated Respiratory Symptoms: A Cross-sectional Study [PDF]

open access: yesIranian Journal of Medical Sciences
Background: Epidemic thunderstorm asthma is an observed increase in cases of acute bronchospasm following thunderstorms. This study aimed to compare the frequency of obstructive airway disease or bronchial hyperresponsiveness in subjects with ...
