[The role of the autonomic nervous system in regulating the excretory function of the stomach in irradiated dogs].
Dogs and rats were exposed to gamma/neutron- and X-radiation. The anterior part of dog's stomach was exposed to 10 Gy and 13 Gy respectively; rats were subjected to whole-body irradiation with absolutely lethal doses. Prior to irradiation, various parts of the vegetative nervous system of both types of animals were "switched off" pharmacologically. In addition to clinical investigation of radiation sickness, the excretory function of the stomach was studied by the excretion of intravenously injected neutral red. The "switching-off" of the parasympathetic nervous system prior to irradiation stabilized the excretory processes in the stomach, increased the resistance of animals, and, vice versa, the "switching-off" of the sympathetic nervous system destabilized the excretory processes and decreased the resistance of the organism.
