POST-TRAUMATIC DEGENERATION AND REGENERATION OF SYNAPSES IN THE ACTION OF IONIZING RADIATION

TL;DRAbstract

A study was made of degeneration and regeneration of synapses in the upper cervical ganglion and section of the sympathetic trunk on the neck of cats after total single x ray irradiation in a dose of 30, 100, or 500 r. There was an acceleration of these processes after the action of low doses, and delay after the action of high doses. The synapses first restored undergo considerable structural changes with the lapse of time and become small and delicate. The scar at the site of nerve section considerably diminishes in size after the high doses of x-ray irradiation. (auth)
