The two basic proteins lysozyme and lactoferrin have been isolated from solubilized mucoid sputum from patients with chronic bronchitis in one step by cation exchange chromatography. In sputa from 13 patients with chronic bronchitis their mean concentrations were 0.4 g/l and 0.7 g/l, respectively, representing 6.6% and 11.5% of the total amount of(More)
Albumin, transferrin, alpha1-acid glycoprotein, IgA, IgG, IgM, lysozyme and C3-complement factor have been immunologically determined in sputum and serum samples from 16 patients with chronic bronchitis. The sputa were effectively solubilized prior to the analysis. This is necessary for correct determination of the compositions of sputum. IgA (approx. 3(More)
Sarizotan 1-[(2R)-3,4-dihydro-2H-chromen-2-yl]-N-[[5-(4-fluorophenyl) pyridin-3-yl]methyl] methenamine, showed an in vivo pharmaco-EEG profile resembling that of methylphenidate which is used in attention deficit/hyperactivity disorder (ADHD). In turn, we tested sarizotan against impulsivity in juvenile rats measuring the choice for large delayed vs. a(More)

A viscometer for measurement of sputum viscosity is described. The apparatus makes possible continuous measurement of sputum samples from 5 to 50 ml in volume. It has been calibrated against capillary and rotation viscometers with excellent correlation. The recordings obtained from sputum impressively display the heterogeneity of this material. They render(More)
Addition of lysozyme (1 g/l) to sputum from patients with chronic obstructive lung disease increased the viscosity of the material significantly. The effect was prevented by addition of salt (LiCl) in the high concentration (0.25 mol/l). The sole addition of salt decreased the viscosity of native sputum. These results together with our earlier [5] studies(More)
