[Neurovascular autoregulation of the regeneration of nerves in the upper extremities].

Functional features of tissue microcirculation in injury and regeneration of nerves were revealed from analysis of 440 polarograms and capillarograms recorded in 30 healthy individuals and 70 patients with sequelae of injury to the median and ulnar nerves. The initial regeneration of the nerve trophic function proper increases the level of microcirculation and oxygenation of the tissues and thus prepares them for the subsequent reinnervation and is conducive to the trophics of the penetrating axons. "Neurovascular autoregulation" of nerve regeneration takes place. A microcirculatory approach to control of the regeneration of nerves makes it possible to study their trophic function proper, identify the presence or absence of anatomical interruption of the nerves, and study the early regeneration stages before the nerve impulse function is restored.
