[Effects of parathormone on 45Ca2+ accumulation in neurosecretory cells and contents of vasopressin in blood after administration of parathyroidin in parathyroid gland insufficiency].
The functional state of hypothalamic-hypophyseal-neurosecretory complex was studied in parathyroidin injection and hypofunction of the parathyroid glands. In these conditions vasopressin levels in blood of the rats increased. The incubation of the hypothalamus with parathormone and 45Ca2+, as well as the injection of parathyroidin increased 45Ca2+ transfer to the neurosecretory cells and vasopressin release in the blood. Various mechanisms of similar influence of the parathormone and hypofunction of the parathyroid glands on a vasopressin level in blood are discussed.
