[Reaction of sensory neurons of the spinal ganglia to sectioning of their peripheral and central processes].
Transversal ++semi-sectioning of the spinal ganglion (SG) is a good model for studying the reaction of the ganglional sensory neurons to sectioning of their peripheral and central processes. At sectioning the peripheral and central processes of the SG neurons degeneration of the neurons and their death take place. The degenerative processes are more pronounced in the neurons with the peripheral processes sectioned, and the restorative ones-with the central processes sectioned. The dynamics of the posttraumatic changes in absolute number of the neurons, profile areas of the body fields and neuronal nuclei, amount of neurons with certain signs of axonal reactions in the SG demonstrate a maximally pronounced reaction on the 7th day and beginning of restorative processes on the 15th day. They are not completed by the 180th day.
