Vasopressin Secretion

Ingestion of water stimulates a powerful inhibitory input to secretion of arginine vasopressin (AVP) in many species. A previous study in dogs has suggested that the stimulus arises from activation of oropharyngeal receptors, but the nature of the stimulus is unknown. The objectives of this study were to determine if the taste, osmolality, or temperature of the solution ingested constituted an important element in the inhibitory mechanism and if these same attributes affected the volume ingested in response to 24 h of water deprivation in conscious dogs. Experiments consisted of a control period, a 6-min period of access to fluid, and a 60-min period after drinking, with blood samples taken frequently to assess changes in plasma AVP. Dogs were placed in a sling that allowed them to stand or lie supported with easy access to a bowl. The solutions were water at 20 and 38 degrees C; 0.9% NaCl at 20 and 38 degrees C; 1.8 and 2.7% NaCl at 20 degrees C; 5% glucose and mannitol and 10% mannitol at 20 degrees C; and liquified food at 20 degrees C. In the time-control experiment dogs were allowed to see but not drink water for 6 min.(ABSTRACT TRUNCATED AT 250 WORDS)

1. Urinary excretion of digoxin-like immunoreactive factor and arginine-vasopressin and other parameters related to salt and water metabolism were studied in hyper- and hypo-thyroid rats after different tests. 2. Urinary excretion of arginine-vasopressin was increased in hyperthyroid and reduced in hypothyroid rats with respect to controls, in response to water deprivation or a hypertonic saline load. 3. Control and hypothyroid rats showed the highest urinary excretion of digoxin-like immunoreactive factor after a hypertonic saline load. However, hyperthyroid rats had the highest urinary levels of digoxin-like immunoreactive factor under normal conditions. 4. From these results it is suggested that: (a) hyper- and hypo-thyroid rats exhibit hyper- and hypo-responsiveness of arginine-vasopressin secretion to osmotic stimuli, respectively; (b) an unidentified digoxin-like immunoreactive factor measured in unextracted rat urine may be related to diuresis and natriuresis in control and hypothyroid rats; however, dissociation between this factor and natriuresis is observed in hyperthyroid rats.

Vasopressin Secretion

The roles of oropharyngeal and gastric factors in satiation and arginine vasopressin (AVP) secretion were examined in water-deprived dogs. Dogs were prepared with chronic gastric fistulas and received six treatments after 24 h of water deprivation: rehydration with H2O or extracellular fluid (ECF) with the fistula closed; rehydration with H2O or ECF with the fistula open; gastric administration of H2O or ECF via the fistula. Drinking occurred immediately after presentation and was always completed by 6 min. At the end of the 60-min period of observation, water was offered in order to assess the degree of satiety. No differences were observed between the volumes of H2O or ECF consumed. However, only absorption of the water drunk produced complete satiety assessed 60 min later. Drinking H2O caused a fall in plasma AVP 6 min before a detectable decline in osmolality and reached water-replete levels by 15 min after drinking. Drinking H2O or ECF plus removal via the fistula and drinking ECF also brought about a rapid decline in plasma AVP without any change in plasma osmolality. Gastric administration of H2O caused a fall in plasma AVP that coincided with the fall in osmolality, and gastric administration of ECF had no effect on plasma AVP. We conclude that oropharyngeal factors account for temporary satiety and the rapid inhibition of vasopressin secretion.

1. Five normal subjects were studied before and during treatment with carbamazepine. 2. Plasma sodium, plasma and urine arginine-vasopressin and urine osmolality were measured during a day of water deprivation, before and during drug treatment. 3. During treatment with carbamazepine plasma sodium increased whereas plasma and urine arginine-vasopressin and urine osmolality decreased. Plasma and urine arginine-vasopressin were significantly correlated with urine osmolality. However, carbamazepine did not affect the osmolality of urine produced by the kidney, in response to endogenous arginine-vasopressin. 4. Plasma and urine arginine-vasopressin were significantly correlated with plasma sodium on both control and drug-treatment days, but the relationships of plasma and urine arginine-vasopressin to plasma sodium were different during carbamazepine treatment, as compared with the control period. 5. It is suggested that the threshold of the hypothalamic osmoreceptors for release of arginine-vasopressin is modified by carbamazepine, and that this may be either a direct action or secondary to another action of the drug.

Von Willebrand’S Disease

SummaryWe have investigated the effects of 1-desamino-8-D-arginine vasopressin (DDAVP) infusion on platelet count and bleeding time in 4 patients with type IIB von Willebrand’s disease (vWd). Three of four patients showed a normalization of the bleeding time within 1 h after the infusion, while bleeding time was not modified in the fourth. In accordance with the literature, thrombocytopenia was observed after DDAVP infusion, but this thrombocytopenia was due to the anticoagulants used for blood collection. In two patients (F. I., G. F.) no thrombocytopenia was observed when platelets were counted by fingerstick method but there was a 20% platelet decrease in blood samples collected in sodium citrate and a 50% decrease in samples collected in EDTA. Dramatic falls in platelet counts (70–95%) were observed in the additional two patients (C. A., D.Z.) after DDAVP infusion, when both sodium citrate or EDTA were used as anticoagulants. In the latter two patients there was also a 50% decrease in platelet count when the fingerstick method was used. The decrease in the patient’s platelet count in EDTA samples after DDAVP infusion could be prevented, in part, by the previous additions of an anti GPIb monoclonal antibody and an anti GPIIb-IIIa monoclonal antibody.Thus, the thrombocytopenia observed in the four IIB vWd patients studied after DDAVP infusion seems to be, at least partially, a pseudothrombocytopenia depending on the calcium concentration in the blood samples and the availability of GPIb and GPIIb-IIIa receptors. These findings and the normalization of the bleeding time observed in three of the four patients has led us to reconsider the possible use of DDAVP in the treatment of our IIB vWd patients.

The gonadal axis is thought to modulate adrenocorticotropic hormone (ACTH), arginine vasopressin (AVP), and plasma renin activity (PRA) responses to stimuli in several species. These experiments were designed to compare the responses to hypotension in chronically ovariectomized ewes and intact ewes. The ewes were infused with nitroprusside at rates of 5, 10, or 15 micrograms.kg-1.min-1 or infused with vehicle for 10 min. The response to 15 micrograms.kg-1.min-1 was also tested with or without treatment with 10 mg of dexamethasone 2 h before nitroprusside. Blood samples were collected before and at 5, 10, 15, 20, and 30 min after the start of the infusion for measurement of plasma ACTH, AVP, and PRA. In both groups of animals there were significant responses to hypotension. There was a significant effect of ovariectomy on ACTH, AVP, and PRA responses. ACTH and PRA responses were lower in the ovariectomized ewes; AVP responses were increased in the ovariectomized ewes. Administration of dexamethasone inhibited ACTH responses and did not inhibit PRA responses in both groups of ewes. Administration of dexamethasone did not inhibit the AVP response in the intact ewes but did reduce the response in the ovariectomized ewes.

Device Implantation

A device for chronic implantation was developed that allowed sampling of cerebrospinal fluid (CSF) from the anterior part of the third cerebral ventricle (A3V) of dogs in repeated experiments for up to 4 mo. Osmolalities, electrolyte concentrations, and concentrations of arginine vasopressin (AVP) measured with a radioimmunoassay were determined in repeated experiments on the chronically prepared animals under conditions of normal hydration, both in the conscious state and during inhalation anesthesia. In conscious dogs, AVP concentrations in plasma and CSF were 3.3 +/- 0.4 and 21.8 +/- 2.5 pg X ml-1, respectively. During anesthesia without surgical interference, the AVP concentrations in plasma and CSF were increased twofold above the levels obtained in conscious dogs. During the time of observation (180 min) all measured parameters remained constant. The AVP concentrations in plasma and CSF samples collected during the surgical procedure of device implantation were about 10-fold higher than in the samples collected during the conscious state. Thus, in each experimental condition, AVP concentration in the CSF collected from the A3V was consistently higher than that in the simultaneously collected blood samples.
