Summary

The author studied the condition of interneuronic synapses in the superior cervical sympathetic ganglion of adult cats after a single total x-ray irradiation in doses of 30, 100, 500, and 1200 r. Argentophilia of the synapses was noted on the 9th day after the irradiation in the animals (100 r). On irradiation with a dose of 500 r, such changes occurred by the 7th day, whereas, with a dose of 1200 r, on the 5th day. Comparison of the synaptic structures according to the series on the 9th day after irradiation demonstrated that the morphological changes were greater, the higher the irradiation dose. Synapses were restored in 2–2.5 months in the animals which survived, after irradiation with sublethal doses.
