A nonlinear mathematical model of blood flow in a vessel 
has been constructed where blood is considered as a suspension with 
aggregating and deformable particles and vessel walls possess elasticity 
according to the Hooke law. The blood viscosity, which is dependent 
on the gradient of the rate of shear on the vessel wall, becomes a 
function of the time in the case of pulsatory motion. The cases of 
normal blood flow in eye vessels and of that in diabetes mellitus 
have been considered as examples. It has been shown that in the latter 
case the contribution of the aggregability of erythrocytes to the 
value of the viscosity of blood substantially increases.
