Effect of the parathyroid hormone—Calcium system on functional activity of the hypothalamus-neurohypophysis complex

The effect of single and repeated parenteral administration of parathyroid hormone on the protein synthesis in neurosecretory cells of the supraoptic nucleus and on the blood vasopressin content is studied. The hormone enhances the synthesis of RNA in the supraoptic nucleus and the blood vasopressin content, particularly after a single administration.
