3-hydroxy-3-methylglutaryl-coa reductase inhibitors (statins), are effective serum cholesterol-lowering agents which also have anti-inflammatory properties. the objective of this study was to evaluate the effect of atorvastatin on bronchial hyperresponsiveness. adult patients (age 14 to 65 years) with bronchial hyperresponsiveness (bhr) diagnosis based on the spirometry with methacholine challe...

the purpose of the present study is to investigate the prevalence of th17 and regulatory t (treg) cells in children with allergic rhinitis (ar) accompanying with bronchial asthma (ba).24 children with ar, 22 children with ba, 18 children with ar accompanying with ba,and 20 healthy controls were recruited. the prevalence of peripheral blood th17 and treg cells were determined by flow cytometry. ...

Sulfur mustard (SM) is a strong alkylating and mutagenic compound that targets humanairway system. We considered the expression of Forkhead box M1 (FOXM1) and apolipoproteinE (APOE) genes, which are responsible for cell proliferation, differentiation, tumorigenesis,and increased risk of lung cancer, in the lung bronchial tissue of patients exposed to SM.After performing pulmonary functional tes...

glutaraldehyde is commonly used in endoscopy labs to clean and disinfect instruments. it can cause direct irritation of the skin and the upper and lower airways. health care workers are also at risk for the development of irritant-induced or sensitizer-induced occupational asthma when exposed to this chemical. herein, we report on a patient who had frequent exposures to glutaraldehyde over one ...

BACKGROUND Overall expression of neurotrophins in the respiratory tract is upregulated in infants infected by the respiratory syncytial virus (RSV), but it is unclear where (structural vs. inflammatory cells, upper vs. lower airways) and why, these changes occur. We analyzed systematically the expression of neurotrophic factors and receptors following RSV infection of human nasal, tracheal, and...

INTRODUCTION While spirometry plays a key role in diagnosing chronic obstructive pulmonary disease (COPD), imaging methods including endobronchial ultrasound (EBUS) and chest computed tomography (CT) appear to be useful for investigating structural changes in the lungs. OBJECTIVES The aim of this study was to evaluate remodeling in COPD patients using EBUS and chest CT. PATIENTS AND METHODS...

Eosinophilic granulomatosis with polyangiitis formerly named “Churg-Strauss syndrome (CSS)” is a systemic disease with bronchial asthma, hypereosinophilia, and systemic vasculitis. We report a case of CSS with cholecystitis and mononeuritis multiplex. A 50-year-old woman with a history of sinusitis and bronchial asthma of 8 years’ duration was referred with a complaint of left-hand deformity an...

Mucociliary clearance velocities in bronchial airway generations were calculated in asymmetric multiple-path models of the bronchial tree by solving mass transport equations based on the assumption of conservation of mucus volume and normalized to measured tracheal mucus velocities of 5.5 mm/min for humans and 1.9 mm/min for rats. Average mucus velocities decreased in a roughly exponential fash...
