title: [Experimental investigation of the effect of segmental blood supplies to peripheral nerves on their axonal regeneration].
abstract: Experimental investigations, with median nerve of adult cat, of axonal regeneration in nerve graft, fresh and predegenerated, with or without segmental blood supply gave following results. Four different kinds of nerve graft were performed in 4 groups. In group A and B, fresh 3 cm nerve graft was placed with or without segmental blood supply, respectively, and in group C and D, predegenerated nerve graft was placed with or without segmental blood supply, respectively. Number of regenerated axons was more and its diameter was larger in group A, compared with group B, within 2 months postop., but those became nearly equal after 3 months postop. In group C, the number of axons remained more and its diameter larger than in group D until 3 months postop. Of 4 groups, regenerated axons outnumbered other groups in group C, but mean diameter of them was the largest in group A.
