... in vasopressin synthesis that are inherited as autosomal dominant, autosomal recessive or X-linked recessive traits. The diagnosis of the underlying condition is challenging and raises several concerns for patients and parents as it requires long-term follow-up. Proper etiological diagnosis can be achieved via...

...J.J. Legros; V. Geenen When they were discovered by Acher and co-workers, neurophysins were thought to act as carriers for the active nonapeptides vasopressin (AVP) and oxytocin (OT) and were then recognized as the inactive fragment of a precursor with a higher molecular weight (propressophysin...

...Yasumasa Iwasaki; Kunikazu Kondo; Haruhiko Hasegawa; Yutaka Oiso Neurohypophyseal function was studied by hypertonic saline infusion with plasma vasopressin measurement in 3 patients with adrenal insufficiency before and after cortisol replacement. Although each patient had different causes...

... and circadian variation in the vasopressin (AVP) cell number of the SCN was observed in relation to the variation in photoperiod. During normal ageing, the circadian variation and number of AVP-expressing neurons in the SCN decreases. The sexually dimorphic nucleus (SDN), intermediate nucleus or INAH-1...

... peptides, namely vasopressin and oxytocin, are themselves capable of modifying behaviour. In this paper the author discusses current understanding of the anatomy and physiology of the main central vasopressinergic and oxytocinergic pathways, followed by a description of the principal actions of exogenously...

...G. Hamon; S. Jouquey The effects of opiates on vasopressin secretion have been controversial for many years. This is probably due to the existence of different types of opioid receptors and to the lack of specificity of the compounds used. Specific ĸ agonists, which have been described recently...

In recent years, the use of a sensitive radioimmunoassay for plasma vasopressin has implicated the role of nonosmotic vasopressin...

...M. Thibonnier In this article, the discrete modifications of the structure of the vasopressin molecule which led to the development of specific V 1 vascular, V 2 renal, and mixed V 1 /V 2 analogs are reviewed. Particularly, the third generation of vasopressin antagonists produced by deletions...

...Jane Garland; Athanasios P. Zis In order to further examine the possible role of endogenous opioid peptides and vasopressin in the phenomenon of dexamethasone nonsuppression, we studied the effect of naloxone, vasopressin, and vasopressinnaloxone combination on cortisol secretion following...

...T. Barreca; R. Franceschini; C. Siani; A. Cataldi; N. Francaviglia; C. Silvestro; E. Rolando Arginine vasopressin (AVP) concentrations were determined in plasma and in cerebrospinal fluid (CSF) in 8 adult male patients suffering from hydrocephalus of various etiologies, before and after intravenous...

...J.J. Legros; M. Ansseau Basal plasma vasopressin-neurophysin (hN p I) was estimated in 50 drug-free neuropsychiatric patients classified according to the Research Diagnostic Criteria. The hN p I concentration was higher in the 5 manics (0.76 ± 0.15 ng/ml) than in the 16 schizophrenics (0.53 ± 0.08...

...Sophia Ish-Shalom; Simona Ben-Haim; David Barzilai; Zeev Hochberg This report describes a 38-year-old patient with prolactinoma, without adrenal or thyroid insufficiency, with syndrome of inappropriate secretion of vasopressin due to downward resetting of the hypothalamic osmoreceptors.

... and osmotic, threshold tests. The presence of endogenous vasopressin, and the normally functioning volume receptors, was demonstrated by the normal urine osmolality during dehydration. The osmotic threshold was 263 mosm/kg on one test and 300 mosm/kg on the other. More extreme values might be suspected based...

...F.H. Katz; J.A. Smith; J.P. Lock; D.E. Loeffel Plasma concentrations of vasopressin and plasma renin activity were measured every 30 min for 24 h in 5 normal active humans, in 1 normal woman confined to bed (except for brief periods up to the bathroom), in 2 active patients with primary...
