... significant changes in basal plasma levels of vasopressin-associated neurophysin (VP-RNP) and oxytocin-associated neurophysin (OT-RNP). In response to intravenous infusion of 18% saline, all three groups of rats had similar rises in Posm. The slopes of the relationship between the rise in plasma VP-RNP...

.... Acute salt-loading was induced by intravenous infusion of 18% saline in conscious, chronically catheterized animals and the activities of VP-neurons and OT-neurons were interpreted from plasma concentrations of VP-associated neurophysin, [VP-RNP] and OT-associated neurophysin, [OT-RNP] at different time...

...- and 90-day groups. Each experimental group was divided into two subgroups that were injected with 7 µg colchicine into either the cisterna magna or the lateral cerebral ventricle. The hypothalamo-neurohypophysial system was investigated immuno-cytochemically using an antiserum against both neurophysins...

... nucleus is depolarized with high K + solutions, hormone is released into areas close to the nucleus. Similar experiments with guinea pig hypothalamus suggest that neurophysin may also be co-released with oxytocin and vasopressin. Use of acetylcholine to selectively stimulate vasopressin neurones appears...

...Judy E. Stern; Teresa Mitchell; Victoria L. Herzberg; William G. North Secretion of the neurohypophyseal principles arginine vasopressin, oxytocin, vasopressin-neurophysin, and oxytocin-neurophysin by hypothalamic-neurohypophyseal explants in organ culture was studied. The viability of explant...

...Ania C. Reinharz; Marcella Klein; Robin E. Offord; Michel B. Vallotton We have compared the immunoreactive oxytocin neurophysin from the human pineal gland with human neurohypophyseal neurophysin. The two proteins were reduced and carboxymethylated with [ 14 C]-iodoacetic acid. Since the pineal...

..., neurophysins, corticotropin-releasing hormone, and γ-amino butyric acid. In addition, functional interactions were demonstrated by the presence of close appositions of NPY fibers with Y5-ir expressing cells. The wide distribution of the Y5 receptor-ir, as well as the colocalization within specific neuronal...
