Shear rate dependent viscoelastic behavior of human glandular salivas.

摘要: Rheological properties of unstimulated human whole saliva (CHWS) and glandular salivas (parotid, submandibular, sublingual, palatal) 7 healthy persons were investigated. The viscosity eta' elasticity eta" these measured as a function oscillating shear rate gamma on an capillary viscoelasticity analyzer (Vilastic 3). Viscosity total decreased in the following order: SL > Pal approximately CHWS SM Par. behavior palatal sublingual displayed comparable pattern, although showed significantly higher absolute values. difference between submandibular was not due to differences mucin concentration saliva. Flow curves range dilutions flow concentrated that intrinsically more elastic than
