[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.

[Regeneration of the rat sciatic nerve after various experimental lesions (morphologic and morphometric analysis)].

Dynamics of structural restoration of the peripheral nerve (n. ischiadicus) have been studied in the noninbred rats in 3 series of experiments: after local freezing, pinching and cutting with a subsequent connection of the nerve ends by means of an implanted arterial vessel. As demonstrate the methods of light and electron microscopy, myelinization of the nervous fibers in the distal part of the nerve begins between the 10th-20th days after the effect.
