Comparison With Methacholine Inhalation in Asthmatics
reactivity (AHR), because of inherent problems with using a pharmacologic agent in epidemiologic surveys. To our knowledge, no studies exist that compare MIC with EVH in known asthmatics. We conducted a prospective, randomized, crossover trial with a group of subjects (n = 16) who met the American Thoracic Society definition of asthma with these objectives: (1) to compare the sensitivity of EVH...
متن کاملComparison of nasal responsiveness to histamine, methacholine and phentolamine in allergic rhinitis patients and controls.
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 histamine chloride was better at discriminating between healthy subjects and patients than methacholine or phentolamine. This discrimination w...
متن کاملThe Fungi Flora of Healthy Nasal Mucosa in Kerman, Iran
Introduction: Environmental fungi, molds and yeasts, can infest the nasal cavity through inhaled air. There is some evidence that they could be the main cause of Chronic Rhinosinusitis (CRS) but little is known about the normal fungal flora in the human nose. The objective of this study was to assess the normal fungal flora of the nasal mucus in adults in Kerman. Materials and Methods: We ...
متن کاملDissociation between airway responsiveness to methacholine and responsiveness to antigen.
Repeated aerosolized antigen challenges to brown Norway (BN) rats generate nonspecific airway hyperresponsiveness (AHR). On the other hand, some studies have demonstrated that repeated antigen challenge could attenuate antigen-specific AHR in BN rats. The authors questioned whether such dissociation in airway responses actually occurs when assessed in a single study in the same animals. The aut...
