Talk:Vasopressin

message: I feel like this article should be moved to Vasopressin.  First of all, it would allow us to quickly get out of the way the issue of arginine vasopressin vs. lysine vasopressin.  More importantly, the actions of vasopressin go way beyond water retention, etc..  ADH is a pretty outdated name.  AVP has a lot of important neuralpeptide actions, as a social recognition signal in the forebrain.  Hard to get into this in the current article structure and with the current title.  --Chinasaur 19:14, 28 Jan 2005 (UTC)
replies: text: Vasopressin is probably a good title, and is increasingly being used instead of ADH. It is, incidentally, still not indicative of its function outside the vascular and renal signal transduction systems. Could you please add more about the social recognition signal role?

text: The articles are identical: vasopressin redirects here. Why is urea reabsorption so important in this article? JFW | T@lk 15:39, 25 January 2006 (UTC)
replies: text: ADH's effect on urine concentration isn't only due to its effects on water permeability; a large part of this effect is from ADH's contribution to the osmolality of the medullary interstitium, which is where urea is of great importance. ADH acts on the inner medullary collecting tubules, raising their permeability to urea and allowing its reabsorption. This raises the interstitial osmolality substantially (by as much as 500-600 mOsm/kg), which — combined with the increased collecting duct water permeability — drives the reabsorption of water from the collecting duct, leading to highly concentrated urine. --David Iberri (talk) 03:47, 15 March 2006 (UTC)

In the context of AVP, parvocellular refers to cells of the paraventricular nucleus. So no linkage necessary. --David Iberri (talk) 18:03, 6 April 2006 (UTC)

thread_title:  caffeine and vasopressin- Reference?  

message: The name vasopressin is indeed outdated, all newer textbooks I've seen use ADH. Vasoconstriction is only a tertiary fuction of this hormone expressed in the extreme case of hemorrage. Its main function is homeostasis as antidiuretic hormone therefore ADH is definitely a more appropriate name. EerieNight 11:02, 25 August 2007 (UTC)
replies: text: You may believe that vasopressin is outdated, but that train has left the station.  The international nomenclature commission has assigned vasopressn and AVP as the official name and symbol, respectively, for the gene and peptide. And, although ADH describes its action at the kidney, it fails as much as AVP does to describe the equally important actions of vasopressin at the pituitary and within the brain.AlbertHall 16:52, 25 August 2007 (UTC)

thread_title:  In need of Revision 

message: The section describing the interaction of vasopressin and behavior is, like too much scientific and medical writing, a maddening exercise in circumlocution. For Pete's sake, state what the hormone does or doesn't do and let the article be revised by someone else in the future rather than write an article for the ages so open-ended that it ought not to have been written at all because it says absolutely NOTHING.
The description of G protein signaling by G alpha s within the "Kidney" chapter is a crap.
G protein alpha subunit does exchange GDP by GTP for activation and not - as described here - vice versa.
The cyclisation of ATP to cAMP does not provide 2 anorganic phosphates. Indeed, one molecule of pyrophosphate is produced.
cAMP may regulate the gene repressor of PKA. However, this cellular response would be far to slow. For fast response reactions the interaction of cAMP to regulatory subunits of PKA is important, resulating in the release of PKAs catalytic subunits.  —Preceding unsigned comment added by 85.179.128.249 (talk) 15:25, 10 March 2008 (UTC)
thread_title:  This article should be revised 

message: To explain a small (but important) edit I made...
Previously, the article stated that ADH retains water, but not salt.  This is not entirely true.
ADH's primary function is indeed to increase water permeability in the collecting system.  However, ADH also stimulates Na/K/Cl cotransport (in the thick asc. limb of loop of Henle), and stimulates apical Na channels in collecting tubules.  Source: Boron & Boulpaep, Medical Physiology, Updated Ed., p. 787.
I have changed the page (removing the words "but not salt").
Enclosed please find a helpful reference for sodium reabsorption by - acute - admionitration of AVP, with serveral further referecnes, which one might use as citation within the article. Chronic administartion of AVP has not been studies so far. AVP has an intrinsic activity on the amiloride-sensitive sodium channel ENaC of the collecting duct of the kidney, and the epithelium of the colon (Bücker 2018), with increased reabsortion of Na. however Na absortion might require highter concentrations of AVP than water reabsorption.

replies: text: Generally, the preprohormone's name is the same as the major hormone. In the cases of vasopressin and oxytocin, they are just the vasopressin preprohormone and oxytocin preprohormone, respectively. Therefore, the article is accurate in just saying that vasopressin comes from a preprohormone. Interestingly, there are only 9 Google hits for the term preprooxyphysin and none for a preprovasophysin.  AlbertHall (talk) 15:32, 9 March 2009 (UTC)

message: I realize such assertions seem unwelcome sometimes, but I wish to call attention to a specific lack of rigor with regard to (1) the use of the term peripheral resistance, and (2) the belief that the mammalian arterial pressure is regulated via any mechanism involving the direct control of generalized peripheral resistance. This latter concept reached its heyday forty years ago when Frank Netter illustrated ads for Ciba-Geigy's Apresoline. The simple fact is that the net venous return is a real measurable phenomenon, and peripheral resistance is an artificial concept defined by a word experiment. The net venous return at the heart is the sum of all the local blood flows. Each local blood flow is determined by local arteriolar diameters, which in turn relate to specific local mechanisms — from oxygen tension in many cells to carbon dioxide in others. Also, when autonomic neurohormonal factors override local mechanisms, the various results can include death from shock. Remember, we are talking about Homeostasis, not the Ischemic Reflex. Local arterioles MUST respond to changes in BP in order to provide the correct local flow. Not the other way around. Every physiologist knows this. Since Harvey. 
Most engineers would understand how these circulatory systems are easily described as elastic reservoir trees interconnected with programmable peripheral current sources, and a variable transconductance amplifier heart.  However, a simple experiment can show it far more easily. My father did this at Emory University School of Medicine in 1945. Some number of subjects are tested on a ballistocardiogram (which estimates cardiac output). Their pressures are measured before and after by cuff. Between measurements, you release a previously attached tourniquet from one or both legs, and the blood rushes in due to reactive hyperemia. This shows a 2X to 5X increase in total blood flow. Yet blood pressures are still well regulated here, showing both small increases and decreases, presumably related to discomfort or fear in the procedure. 
Based on my studies at my father knee, and extensive simulations in the Pennsylvania State University Hybrid Computer Lab and the Penn State mainframe (1976), the sensitivities of the mammalian circulation to small changes in "Total Blood Flow" (a proxy for "PR") would never keep pace with the big blood flow changes that are otherwise normal among organs doing their normal jobs. Simulations suggest that short term regulation seems reasonably likely by modifying the heart function (increased contractility and hear rate) and long term arterial blood pressure control is synonomous with body fluid level control, especially the total blood volume. Other mechanisms (rather than direct control of PR) seem likely as well. Arthur Guyton tried to bring this out, but he lacked credibility as a theorist later in his career. Vasodilators, obviously, can have a big impact on blood volume if they act on the kidneys. In this way, I would expect them to work, but _not_ because they overperfuse tissues or cause a cardiac output that would kill you. 
Therefore, I hereby dispute the statement "It also increases peripheral vascular resistance, which in turn increases arterial blood pressure." I challenge anyone to produce scientific evidence to support it. It is _not_ common knowledge; it is a common misconception. If you remove that ONE sentence, the remaining paragraph actually describes well enough (for me) how Vasopressin controls [arterial] blood pressure by helping to manage water, salt, and kidney functions. 
Please remove that ONE sentence. It is a small (even if some might feel outrageous) request on behalf of scientific rigor and the facts. Having stated a bias here, I should not do it myself. Should I?

Ventricle (Romanowsky 2003, Nakamura2011) , both areas have interleukin-6 receptors (Swart 2011), are stimulated by non-osmotic stimuli, i.e. IL-6, In other words: fever due to IL-6 released from monocytes, PMN, or further to that from central cells inside oft he blood-brain-barrier,  such pituicytes  will release AVP thru activation of osmocentre from the pituitary, causing hyponatremia due to water reabsorption at the kidney,i.e. dilutuion of plasma, similar to SIADH (Mastorakos 1994), which is different from salt wasting. Acute – not chronic - fever as a course of AVP release is now a well now fact in clinical settings, such as bacterial tuberculosis, or viral SARS, Dengue etc.
