	Vasopressin - Wikipedia, the free encyclopedia
		Vasopressin is a peptide hormone liberated from a preprohormone precursor that is synthesized in the hypothalamus as it is transported to the posterior pituitary.
		Vasopressin is secreted from the posterior pituitary gland in response to reductions in plasma volume and in response to increases in the plasma osmolality.
		Vasopressin is released into the brain in a circadian rhythm by neurons of the suprachiasmatic nucleus of the hypothalamus.

	Arginine (L-arginine) - MayoClinic.com
		Arginine is a precursor of nitric oxide, which causes blood vessel relaxation (vasodilation).
		Preliminary evidence suggests that arginine may be useful in the treatment of medical conditions that are improved by vasodilation, such as angina, atherosclerosis, coronary artery disease, erectile dysfunction, heart failure, intermittent claudication/peripheral vascular disease, and vascular headache.
		Arginine has been well tolerated by most people in studies lasting for up to six months, although there is a possibility of serious adverse effects in some individuals.

	MedlinePlus Herbs and Supplements: Arginine (L-Arginine)
		Arginine is considered a semi-essential amino acid, because although it is normally synthesized in sufficient amounts by the body, supplementation is sometimes required (for example, due to inborn errors of urea synthesis, protein malnutrition, excess ammonia production, excessive lysine intake, burns, infection, peritoneal dialysis, rapid growth, or sepsis).
		Arginine can be a helpful treatment by shifting the way the body processes nitrogen, but should be avoided in patients with hyperargininemia (high arginine levels).
		Arginine supplements are not recommended in children because there is not enough scientific information available and because of potential side effects.

	Vasopressin - Psychology Wiki - A Wikia wiki
		Vasopressin is secreted from the posterior pituitary gland in response to reductions in plasma volume and in response to increases in the plasma osmotic pressure.
		Vasopressin is secreted from parvocellular neuroendocrine neurons of the paraventricular nucleus into the hypothalamo-hypophysial portal vessels of the median eminence.
		The amino acid sequence of arginine vasopressin is cysteine - tyrosine - phenylalanine - glutamine - asparagine - cysteine - proline - arginine - glycine.

		In one of the patients, the same arginine vasopressin doses produced a persistent decrease in forearm blood flow.
		Subsequent administration of DD-arginine vasopressin during L-NMMA infusion produced a slight reduction in the forearm blood flow increase compared with DD-arginine vasopressin alone, but this was significant only for the absolute forearm blood flow increase induced by 10 ng/min per dl in all subjects.

	Product Abstract: Arginine
		Arginine, used in synthesis of body proteins, is essential for ammonia detoxification via urea synthesis, which prevents metabolic derangements caused by elevations in tissue ammonia.
		Arginine at supraphysiologic doses is thymotropic and a secretagogue for hormones that control growth and metabolism.
		Recent studies of intraspecies and interspecies differences in responses to arginine reemphasize that dispensability or indispensability of arginine is a matter of definition and that growth and nitrogen balance data impose significant limitations on the drawing of far-reaching conclusions about the needs for arginine by mammalian adults including humans.

	NEJM -- Abnormalities in plasma and cerebrospinal-fluid arginine vasopressin in patients with anorexia nervosa
		In all four subjects studied before correction of weight loss, the response to hypertonic saline was abnormal: in one, the plasma level of arginine vasopressin increased subnormally relative to the plasma sodium level; in the other three, it fluctuated erratically, with no relation to plasma sodium.
		Abnormalities in the osmoregulation of plasma arginine vasopressin were not accounted for by nonosmotic stimuli and were almost always associated with an absolute increase in the level of arginine vasopressin in the cerebrospinal fluid or a reversal of the normal (less than 1.0) cerebrospinal fluid/plasma ratio of arginine vasopressin.
		These results indicate that most if not all patients with anorexia nervosa have abnormal levels of arginine vasopressin in their plasma and cerebrospinal fluid that are corrected very slowly with weight gain.

		Serum arginine vasopressin concentrations were low in cases of vasodilatory shock, at 12.0 6.6 pg/mL.
		The arginine vasopressin dose administered was 0.01 to 0.1 U/kg, yielding plasma concentrations of 150 pg/mL.
		It is hypothesized that the efficacy of arginine vasopressin is dependent upon its ability to counteract vasodilatory mechanisms.

		The vasopressin (AVP, ADH) receptor subtypes belong to the G protein–coupled receptor superfamily.
		The V1a and V1b receptors signal by activation of phospholipase C and elevation in intracellular calcium, which in turn stimulates protein kinase C. V1a subtype is ubiquitous and found on cells such as vascular smooth muscle cells, hepatocytes, platelets, brain cells, and uterus cells.
		In addition, nonosmotic stimuli for arginine vasopressin release, particularly hemodynamic derangements (eg, due to hypotension, nausea, uncontrolled pain, or drugs) must be excluded.

		Arginine vasopressin (AVP), the naturally occurring ADH in humans, is an octapeptide similar in structure to oxytocin.
		It is synthesized in the cell bodies of neurons in the supraoptic and paraventricular nuclei of the anterior hypothalamus and travels along the supraopticohypophyseal tract into the posterior pituitary, where it is stored in secretory granules in association with a carrier protein, neurophysin.
		This pattern is consistent with an increased renal sensitivity to vasopressin and is observed in patients with bronchogenic carcinoma and diabetes mellitus.
