| Abstract: | Sensory fibers regeneration after dorsal root ganglion (DRG) section was studied in the rat. After middle cross-section of DRG-13 (left side) there were neurons in the proximal part with damage to peripheral processes and in the distal part with damage to central processes. Axonal ionophoresis of cobalt salts was used for the study of sensory fibers regeneration through the scar in DRG during 3, 7, 15, 30, 120 and 180 days after the damage. Peculiarity regeneration of the sensory fibers was shown in spite of damage localization near ganglion cells body, the regeneration of peripheral and central processes of ganglion cells started already on the 3rd day, and sprouting sensory fibers through the scar of DRG--on the 7th day. |
