The author investigited the nerve clements in the dura mater and the eye muscles of ani,als subjected to the radiocobalt (Co/sup 60/) irradiation of daily doses of 1000 to 1500 r in case of rabbits, 400 r in guinea pigs, and 600 to 900 r in rats. The highest radiosensitivity in the dura mater was manifested by the afferent nerve conductors, in 2 to 3 days after the irradiation. Delicate sympathetic fibers were found to be more resistant. The sensory nerves and their endings remain intact in the eye muscles of the same animals. At the same time the motor nerve fibers and their terminal ramifications in the motor end degrees of injury up to complete degeneration and lysis of the end-plate neurofibrillar apparatus from which only the protoplasmic soles are left. As experimentally demonstrated the elements of the peripheral nervous system exhibit a considerable, morphologically minifested, reaction to the action of ionizing radiation. The radiosensitivity exhibited by various peripheral nervous system components is far from being uniform. This depends not only on their nature and functional significance, but also on some still obscure factors. (auth)
