Synthesis, transport, and release of posterior pituitary hormones.

Vasopressin and oxytocin are made and released by neurons of the hypothalamo-neurohypophysial system. Pulse labeling these neurons with radioactive amino acid indicates that the two hormones and their respective neurophysin carrier proteins are synthesized as parts of separate precursor proteins. The precursors seem to be processed into smaller, biologically active molecules while they are being transported along the axon.

Development pharmacokinetics of the posterior pituitary hormones.

Arginine vasotocin, arginine vasopressin, and oxytocin play a critical role in the stimulation of labor and delivery and in salt and water homeostasis in the newborn infant. The authors present information on their chemistry, secretion, and metabolism, and discuss the clinical effects upon target organs of their presence or absence.
