The functionlan condition of adrenal cortex was studied in acute radiation injury. The working capacity of the skeletal and the smooth muscles served as an index of the cortical junction. Experiments were conducted on x-ray irradiated cats given doses of 600 r. The author investigated the Working capacity of gastrocnemius in electric stimulation of the sciatic nerve and of the smooth muscle of the nicti tating membrane in stimulating the postganglionic fiber of the sympathetic nerve. A pronounced increase of the muscular working capacity was observed in 3 days after the irradiation with its subsequent decrease beginning from the 5th day. Definite changes in the nictitating membrane contractile reaction were revealed in the iriadiated amimals in stimulating the postainglionic fiber of the sympathetic nerve. Primary short phase of muscular relaxation in response to switching the current on with its subsequent contraction was noted after the irradiation. There was an additional contractile reaction in switching the current off. These phenemona are regarded as parabiotic. They were removed with decrease of the intensity of the stimulation. Changed frequency of the stimulation had no effect on the character of the reaction. There were no modifications in the character of the contractile reaction of the nictitating membrane in the irradiated animals in stimulating the preganglionic fiber. (auth)
