Tumoral and non-tumoral trachea stenoses: evaluation with three-dimensional CT and virtual bronchoscopy.
BACKGROUND We evaluated the ability of 3D-CT and virtual bronchoscopy to estimate trachea stenosis in comparison to conventional axial CT and fiberoptic bronchoscopy, with a view to assist thoracic… Expand
Endothelin-1 levels in the pathophysiology of chronic obstructive pulmonary disease and bronchial asthma.
BACKGROUND Endothelin-1 (ET-1) has been implicated in the pathogenesis of asthma and chronic obstructive pulmonary disease (COPD). The ET-1 levels are elevated during exacerbations of asthma and COPD… Expand

Can High Resolution Computed Tomography Predict Lung Function in Patients with Chronic Obstructive Pulmonary Disease?
High-resolution computed tomography (HRCT) is a useful method for quantifying the extent of emphysema. Few reports have mentioned the relationships between HRCT scans and pulmonary function tests in… Expand
Antianginal Efficacy of the Combination of Trimetazidine-Propranolol Compared with Isosorbide Dinitrate-Propranolol in Patients with Stable Angina
SummaryTrimetazidine is a new anti-ischaemic drug that exerts cytoprotective effects without modifying coronary blood flow or systemic haemodynamics. We tested the antianginal efficacy of… Expand
Mechanisms of Endothelin-1 Elevation in Chronic Obstructive Pulmonary Disease Patients with Nocturnal Oxyhemoglobin Desaturation
Background: Nonapneic, oxyhemoglobin desaturation associated with sleep has been described in patients with chronic obstructive pulmonary disease (COPD). Hypoxemia stimulates endothelin-1 (ET-1)… Expand
Non-Invasive Estimation of Pulmonary Arterial Hypertension in Chronic Obstructive Pulmonary Disease
Abstract. The feasibility and reliability of the combination of several noninvasive methods using a multivariate method of analysis to predict pulmonary artery hypertension (PAH) is evaluated in 20… Expand
Arterial and bronchoalveolar lavage fluid endothelin-1 concentration in asthma.
Endothelins are a family of peptide mediators that have a number of biological properties, including the ability to act as bronchoconstrictors and vasoconstrictors of isolated airways and vessels.… Expand
Salivary immunoglobulin A production in chronic bronchitis patients given an orally administered bacterial extract.
- K. Spiropoulos, D. Lymberopoulos, G. Garantziotis, C. Gogos
- Respiration; international review of thoracic…
The concentration of secretory immunoglobulin A (IgA) has been measured by the immunodiffusion method in 28 chronic bronchitis patients (group A) and in 11 comparable patients receiving… Expand
