BACKGROUND The development and validation study of the Clinical Chronic Obstructive Disease (COPD) Questionnaire (CCQ) has recently been published in this journal. The CCQ is the first questionnaire that incorporates both clinician and patient guideline goals in the clinical control evaluation of patients with COPD in general clinical practice. The aim of(More)
The rheological behavior and clearance of bronchial mucus samples collected by protected expectoration from 24 out-patients with simple chronic bronchitis were investigated before, at the end of a short period of treatment (4 days) with a single oral dose of 2.7 g (sachet) of carbocysteine-lysine (evening meal), and on the 4th and 8th days after the end of(More)
Here we describe the identification of Toxoplasma gondii circulating antigens in sera of BALB/c mice experimentally infected with either the virulent RH strain, or the cystogenic WTD1 strain or with an isolate from a human patient. The circulating antigens were identified by immunoblot in tachyzoite (RH strain) and in tissue cyst (ME-49 strain) crude(More)
The topical tolerability of an intranasal salmon calcitonin spray preparation, of the excipients alone and of sodium taurocholate has been studied by assessment of the mucociliary transport velocity (MTV) on the frog's palate. The rate of mucus transport was investigated in 3 groups of animals (Rana esculenta; 6 frogs per group) in basal conditions and(More)
The effects of an oxidizing gaseous pollutant on tracheal mucous velocity have been studied in conscious sheep. Acute (2 hours) exposure to 1.0 ppm of ozone showed an effect on tracheal mucous velocity that resulted in a significant decrease 40 minutes and 2 hours after exposure (35% and 40% of the baseline, respectively). Repeated exposure for longer(More)
Proteolytic enzymes can act on the polymeric structure of the bronchial mucus, shortening the long chain of mucoproteins, DNA and other macromolecules, and thus reducing the viscosity of the mucus facilitating its expectoration. Seaprose (Flaminase, Puropharma) belongs to this class and is a proteinase from Aspergillus melleus and it is mainly used in(More)
Nesosteine, a new agent shown to improve physical characteristics of bronchial mucus in animal models, has been studied in chronic bronchitic patients to confirm its effect on viscoelasticity of bronchial secretions. Sputum was collected from hypersecretory bronchitic patients in a stable condition before and after seven days of treatment with nesosteine(More)
