The experiments were staged on dogs subjected to chronic administration of low quantities of Sr/sup 90/ (0.002 mc/kg, 0.02 mc/kg, and 1 mc/kg). Electrocardiographic examinations and studies of the arterial pressure changes with the employment of pharmacological loading of adrenaline and acethylcholine were performed. It was found that chronic action of low concentrations of Sr/sup 90/ changes the functional state of the cardiovascular system. The sensitivity of the heart to adrenaline and acethylcholine rises; moreover, changes of the latter are of phase nature. Soon after the administration of strontium there is noted a prevalent tone of the parasympathetic portion of the vegetative nervous system. At late periods of affection the arterial pressure reaction to adrenaline decreases and dystrophic disorders of the myocardium may develop. (auth)
