title: [Physical properties of tracheobronchial contents in patients with bronchial asthma and patients with nonpulmonary allergy].
abstract: OBJECTIVE
  The study of viscoelastic properties of tracheobronchial contents (TBC) in patients with bronchial asthma (BA) of different severity and in allergic patients free of bronchopulmonary disorders.
  
  
  METHODS
  Viscoelastic properties of TBC were studied in 97 BA patients and 39 allergic patients. 19 of the latter had clinical symptoms of allergy, the rest 20 had the history of allergy.
  
  
  RESULTS
  Viscoelasticity of TBC in patients with clinical symptoms of extrapulmonary allergy was higher than in healthy subjects and was similar to that of patients with mild BA. Viscoelasticity was maximal in patients with moderate BA, while in severe BA it was somewhat less.
  
  
  CONCLUSIONS
  Low viscoelasticity of TBC in patients with severe BA compared to mild and moderate BA and extrapulmonary allergy may be explained by qualitative changes in physical properties of secretion in severe BA.
