Pathological Physiology and General Pathology


A study was made of the extent of sympathin (a sympathetic nervous system mediator) liberation into the fluid perfused through the frog cardiac cavity at the moment of sympathetic nerves excitation. Sympathin (adrenalin) was determined by the method of luminescent analysis. As established, the total x-ray irradiation of frogs in a dose of 4,500 r disturbs the symphatin-forming process. On the 2nd–4th day after irradiation the amount of the sympathin liberated was found to be down and below its normal level; it almost regained from the 5th to the 7th day, but on the 13th–18th day experienced a new considerable drop. Only by the 30th day after irradiation there occurred a gradual normalization of the sympathin-forming process.
