Temperature dependence of the viscoelastic recovery of red cell membrane.

摘要: The time-dependent recovery of an elongated red cell is studied as a function temperature. Before release, the in static equilibrium where external forces are balanced by surface elastic force resultants. Upon recovers its initial shape with exponential behavior characteristic viscoelastic solid material undergoing large ("finite") deformation. process characterized time constant, tc, that decreases from approximately 0.27 s at 6 degrees C to 0.06 37 C. From this measurement constant and independent shear modulus elasticity for membrane, value membrane viscosity temperature can be calculated.
