Changes in the synaptic endings on nerve cells and on the capillary walls of the spinal cord in dogs with acute radiation sickness

Summary

In dogs suffering from acute radiation sickness (the irradiation dose being 450 r) the reaction of synaptic formations in cells and capillary walls consists of two phenomena: a) increased affinity of the synaptic structure for silver (increased argyrophilia); they are detected in numbers, greater than under normal conditions; b) deformation, hypertrophy and destruction of synaptic formations.

The picture of the reactively changed synaptic endings is variable. The presence of intact structures on neurons and capillaries points to the plasticity of the nervous system providing an optimal level of vital processes under given conditions of existence.
