[Effect of x-ray contrast substances in vitro on blood rheological properties].

It has been demonstrated that the radiographic contrast substances (RCS) having a high protein-binding capability, bilignost and endocystobil, exert the most pronounced effects on blood rheological properties, which manifests in an increase in blood fluidity and hydrodynamic strength of aggregates. A reverse, correlation was found between the degree of red cell aggregation and red cell binding with the RCS. The diatrizoate derivatives were shown to have the least significant effects on the rheological properties of the blood.

[Changes in hemorheologic indices during hemorrhagic shock].

Experiments were conducted on dogs. A study was made of interrelationship between the rheological, hemodynamic and metabolic indices in hemorrhagic shock. As found, mechanical properties of the blood altered after the blood loss in parallel with the macrohemodynamic disturbances and preceded metabolic acidosis.
