Apomorphine, a centrally-acting emetic, was administered subcutaneously (50 micrograms/kg) to nine normal subjects (four male, five female; aged 22-36 years) and four patients with idiopathic diabetes insipidus (DI) (one male, three female; aged 24-49 years). In the normal subjects this stimulus
Ipecacuanha syrup induces emesis by an early peripheral (gastric irritant) action and a later central effect at the chemoreceptor trigger zone (CTZ). We have studied the responses of plasma AVP, ACTH and ACTH-precursors to early and late ipecacuanha-induced nausea in nine healthy male subjects.
Familial neurohypophyseal diabetes insipidus (FNDI) is a genetic disorder presenting with polyuria and polydipsia and is caused by mutations in the arginine vasopressin-neurophysin II (AVP-NPII) gene. The clinical manifestations of this disorder vary greatly depending on different mutations. The
Concentrations of plasma arginine vasopressin (AVP) were studied in patients receiving chemotherapy. Of the 18 patients studied, nine experienced nausea and vomiting and the remaining nine were nonvomiters who suffered at worst mild nausea. Plasma AVP in the non-vomiting group remained within the
Nephrogenic syndrome of inappropriate antidiuresis (NSIAD), resulting from activating mutations in the arginine vasopressin receptor type 2 (AVPR2), is a rare cause of hyponatraemia. However, its true prevalence may be underestimated and it should be considered in the investigation of unexplained
Arginine vasopressin 1B receptor (V1B) antagonists may have utility for the treatment of major depressive disorder (MDD).
The V1B antagonist ABT-436 (N = 31) or matching placebo (N = 20) was administered to MDD subjects for 7 days. The main study objectives were to assess the safety and
In order to examine the influence of carotid baroreceptor stimulation on arginine vasopressin secretion, 8 normal healthy males were subjected to static neck suction of -3.3 kPa for 20 min in the upright sitting position after overnight food and fluid restriction. The plasma concentration of
To evaluate the nutritional, metabolic and immune effects of dietary arginine, glutamine and omega-3 fatty acids (fish oil) supplementation in immunocompromised patients, we performed a prospective study on the effect of immune formula administered to 11 severe trauma patients (average ISS = 24), 10
Arginine has been used by millions of athletes over the past 20 years to enhance production of human growth hormone. The effects of arginine supplementation include increased fat burning and muscle building, enhanced immunity, and improvement in erectile function in men. Excessive doses of basic
The response of plasma arginine vasopressin (AVP) to nicotine administered by chewing gum (Nicorette, 2 mg) was examined in nine healthy volunteers. Heart rate, mean arterial pressure, serum osmolality, plasma AVP level, and plasma nicotine level were measured at baseline (control) and at 30, 45,
MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes) is the most representative subtype of mitochondrial diseases. Administration of L-arginine (L-Arg) or a precursor of nitric oxide (NO) has been proposed as a promising medication for MELAS because one of the
Arginine vasopressin (AVP) is a peptide hormone synthesised in the hypothalamus and secreted from nerve terminals within the posterior pituitary gland. Secretion is primarily under osmoregulatory control and levels rise in plasma in response to a body water deficit and are suppressed in response to
Since arginine can stimulate lymphocyte proliferation in the healthy human, its effect on lymphocyte proliferation in vitro was studied in 7 patients with far advanced gastric cancer. These patients with normal nourishment were ambulatory and could consume a regular diet. A daily dietary supplement
Human urine samples, purified on octadecasilyl-silica cartridges, contained immunoreactive angiotensin I, II, arginine vasopressin and oxytocin. The daily excretion of these peptides in healthy volunteers was 190.00 +/- 38.43 (n = 12), 17.48 +/- 3.09 (n = 12), 63.43 +/- 14.84 (n = 8) and 13.52 +/-
The effect of arginine on lymphocyte proliferation in vitro was studied in patients with advanced gastric cancer. Patients who were ambulatory, normally nourished and consuming a normal diet, received a daily supplement of 30 g arginine for 7 days. There was no change in total lymphocyte count, T B
