[Formation of spinal cord cicatrix under various experimental conditions].

Structure of the cat spinal cord scar has been studied by means of light and electron microscopy after its lateral hemisection, complete dissection and hemisection in combination with autotransplantation of the sympathetic ganglion, which keeps its connection with the sympathetic trunk, into the cut of the spinal cord. Three zones are revealed in the scar: central (connective tissue), intermediate (glio-connective tissue) and peripheral (zone of glio-cystous and reactive changes of the nervous tissue). Peculiarities of intercellular reactions are revealed in the process of formation of various zones in the scar and their dependence on the type of the experiment. In the experiments with autotransplantation of the sympathetic ganglion into the spinal cord, a definite possibility to restrict scarry changes of the spinal cord is demonstrated in connection with improving reinnervation and revascularization of the traumatized segment.
