[The effect of small doses of ionizing radiation on the cAMP system in the thyroid gland of chick embryos].
Adenylate cyclase activity and cyclic adenosine monophosphate (cAMP) content were studied in the thyroid gland of intact and irradiated (0.029 Gy given before incubation) embryos and chickens. The enzyme activity was stimulated and the nucleotide content increased on the 18th day of the embryo development. It is suggested that the observed stimulation of the cAMP system is associated with the increased secretion of the thyrotropic hormone which controls the functional activity of the thyroid gland.
