[Morphofunctional asymmetry of the microvascular bed of the rabbit concha auriculae].

Microvessels of rabbit ears chamber and blood samples drawn from the internal ear vein after 30 min ischemia were studied. In the initial state the length of the left ear microvascular bed was 1.5 times higher, mean microvessel diameter 14.6% less, apparent viscosity of outflowing blood 16.8% less, RBC concentration per volume unity of blood 8% higher, RBC electrophoretic mobility 13.7% higher than those in the right one. It was shown that the left microvessel bed responds to the ischemia with the 13.2% increase of its length and 13.6% increase of the outflowing blood viscosity, the right one--with the 9.7% increase of microvessel diameter and 7.9% decrease of the viscosity.
