[Microcirculatory bed of the auricle floor in rabbits after blood substitution].

Microvessels of rabbit ears chamber and blood samples drawn from the internal ear vein have been studied after blood substitution. It has been shown that the left microvessel bed responds to the hemodilution with 38% decrease of its length and 5.9% decrease of the mean diameter of its vessels, decrease apparent viscosity of outflowing blood, but RBC concentration per volume unity of blood (N) being preserved. The right one--with 7.8% increase of microvessel diameter, their length being preserved and 10% increase of the N.
