[Changes in the blood vessels of the spinal cord and spinal ganglia following chronic stimulation of the lumbar regions of the sympathetic trunks and gangliosympathectomy].

Morphological studies in 40 rabbits demonstrated that chronic irritation of the lumbar sympathetic trunks resulted in more pronounced architectonic changes, in vessel walls and in neurons of the lumbar sympathetic ganglia in 15 days than did the bilateral lumbar gangliosympathectomy at the same time. In both series of experiments more prominent changes were noticed in the spinal ganglia than in the spinal cord, that could be explained by different degree of lesions in the nerves supplying them and by organic specification of their angioarchitectonics. The data obtained made it possible to include novocain block (anesthesia) into complex therapy to manage spinal apoplexy in clinic.
