bronchial responsiveness to bronchodilator medications is usually tested to establish reversibility of airflow obstruction. among the various tests to establish bronchodilator response, fev1, fef25-75% or fef50%, and fvc are the most widely used. in a cross-sectional study, we assessed spirometric responses after administration of bronchodilator in 187 workers with obstructive pattern in spirom...

The pattern and clinical implications of bronchial bacterial colonization have been widely investigated in patients with chronic lung disease, particularly chronic obstructive pulmonary disease. The main aim of this study was to determine the frequency and risk factors for bronchial colonization in lung cancer patients who have undergone surgical resection. Forty-one patients with resectable lu...

The extracellular matrix (ECM) influences a variety of cellular functions, including survival, adhesion molecule expression, differentiation, and migration. The ECM composition of the epithelial basement membrane is altered in asthmatics. In this study, we elucidate the major survival signals received by bronchial epithelial cells in vitro by studying the effects of a variety of ECM factors and...

Histamine, administered to dogs by various routes, produced peribronchial interstitial edema. Using colloidal carbon as an electron-dense tracer, it was shown that bronchial venules had become leaky at the same time that the minute blood vessels of the pulmonary circulation remained unaffected by the histamine. The effect of histamine was rapid and brief in duration: wide interendothelial gaps ...

Introduction . One of the important problems medical imaging is differential diagnosis patients with acute and chronic pulmonary embolism. The widely used minimally invasive technique multispiral computed tomography intravenous bolus contrast enhancement can serve to solve this problem, in particular, assess state parenchyma vascular structures lungs. purpose To bronchial arteries parenchymal c...

To document the normal values of pulmonary function tests in children and changes occurring in their values with various respiratory disorders, a study was carried over a period of one year in 95 healthy controls (39 females and 56 males) of 8-13 years of age and 51 cases with respiratory disorders (bronchial asthma-31, pneumonia-10, empyema-10) of matched age, sex and height distribution. The ...

the purpose of this study was to determine the clinical significance of changes in the plasma  adiponectin  concentration  in  patients  with  bronchial  asthma  and  to  test  the association between the single nucleotide polymorphisms (snps) rs2241766 and rs1501299 in the adipoq gene and bronchial asthma in the chinese li population.we selected 120 cases and 120 controls, and plasma adiponect...

CASE SUMMARY Herein we describe an unusual metastatic pattern and paraneoplastic manifestation of a bronchial carcinoma in a cat. An 8 year-old cat presented with a diminished appetite, dysphagia, weight loss, lethargy and coughing. Thoracic radiographs revealed a lung mass. Bronchial carcinoma was diagnosed on the basis of histology and was associated with a lymphoplasmocytic infiltration of t...
