[Dynamics of the recovery of the structure and function of the sciatic nerve and skin receptors in reinnervation of the hindlimb of white rats].

The dynamics of the structural and functional repair of nerve trunks and receptor endings in the rat foot skin was studied on the model of sutureless connection of the damaged nerve by and implanted arterial vessel. Neurohistological and neurophysiological methods were used to show that the anatomical repair of the nerve integrity, maturation of nerve fibers and formation of receptor endings preceded their functional restoration. Terms of myelinization of regenerating axons, their diameters and initial stages of the formation of receptors in the foot skin were established. The restoration of the skin receptor function was shown to occur within 11-13 months after operation.
