[Catecholamine and electrolyte content in the vascular wall of animals with radiation sickness and administered radioprotectors].

Experiments on adult cats have shown that total x-ray irradiation in a single dose of 400 Gy produces different changes in electrolyte and catecholamine metabolism in the aortal wall in response to the injection of varying doses of adrenaline (1.5, 15, 150 mg/kg). Premedication with cystamine (75 mg/kg) lowers the degree and frequency of inadequate changes in the biochemical response of vascular tissue to adrenaline injection in a dose of 15 mg/kg.
