Abstract

The use of biological glue for the repair of nerve lesions offers the possibility of acting on axonal regeneration by means of trophic substances included in the glue. A comparative study conducted in the sciatic nerve of the rat shows that incorporation of the liquid exuded by sectioned nerve extremities into the glue to repair a section of the sciatic nerve trunk of other animals significantly increases the muscular tension of the force jerk and the of tetanic contraction of the reinnervated extensor digitorum longus 21 and 28 days after repair. It therefore appears possible to influence the regeneration or the maturation of the regenerating axons by local application of exogenous substances.
