The use of surface rheology is a convenient way to study the forces arising between surface adsorbed protein molecules. A surface rheological measuring head has been designed for the Contraves LS-30 viscometer. Plasma samples of healthy human subjects showed a rapidly developing viscous surface layer with a mean peak value of 2.10(-3) Ns/m surface viscosity at 30- 60 seconds. After that the viscosity of the surface layer gradually decreased to zero between 8-20 minutes. The rate of the observed decrease was not related to shearing. There was no difference between samples anticoagulated with heparin or EDTA.

Two main types of experimental methods have been used for the characterization of the bulk shear properties of biorheological fluids: (A) In continuous laminar shearing motion, the tangential and normal components of stress are measured at a series of rates of shear. From these parameters, the apparent viscosity, an elastic modulus and a recoverable strain, are calculated as functions of the rate of shear. In this continuous shear experiment, the physical structure present in the material at any given rate of shear may be quite different from the material in its rest state or at other rates of shear. (B) In harmonic oscillatory motion, the material is subjected to a harmonic laminar shear about its rest state at a number of frequencies and small strain amplitudes. From these experiments the dynamic moduli of viscosity and elasticity are calculated. Preparations of biological materials, such as whole blood and systems of blood components, both in health and disease states, have been investigated using methods A and B, together with studies of surface layers of plasma proteins at interfaces.</p>","PeriodicalId":79205,"journal":{"name":"Biorheology.

Different disorders can be described by 'profiles of viscosity factors' which form a rheological fingerprint specific to a particular disease or a group of disorders. Determination of viscosity factors is carried out utilizing a series of instruments: (a) rotational viscometers, (b) capillary viscometers, (c) erythrocyte sedimentation tubes in 20C and 37C water tanks, (d) variable frequency thrombo-viscometer, (e) slit-capillary photo-viscometer, etc. One known factor which is not measured routinely is 'inversion phenomenon', and this is due to complexity and expense of measurements.
