Rheological Properties of Nasal Mucus of Calves During Periods of Development of Bronchopneumonia

摘要

Determination of viscosity and adhesion of nasal discharge is considered to be promising diagnostic tests to evaluate the mucociliary system in calves in case of respiratory diseases. The aim of the study was to find out the rheological properties of sputum in the development of bronchopneumonia. In clinically healthy animals, the viscosity of the nasal exudates amounted to 1.228±0.0238 mm~2/s, and the adhesion -tol.018±0.0375 g/cm~2. At the stage of manifestation of bronchopneumonia, the rheologicalproperties of nasal secretion change with an increase in its viscosity and adhesion.
