C'è un po' di confusione sull'effetto della Calcitonina a livello del tubulo renale. Rettifico una mia precendente affermazione perché sinceramente preferisco lasciare la decisione ad altri ;-)

Copio una parte della discussione nella versione inglese

That's what the article says:

Inhibits Ca2+ and phosphate reabsorption by the kidney tubules[7]

Though the very references number 7 ( http://www.ncbi.nlm.nih.gov/pubmed/9058369 ) says: "It is concluded that in man calcitonin like PTH is a renal Ca- and Mg-conserving hormone."

So according to PubMed's most recent researchs even though calcitonin's action is to reduce calcemia, it's effect on the kidney tubules is to actually enhance Ca2+ reabsorption.

Recent research may show that Ca2+ is reabsorbed in the kidney, but it is by no means an established fact and should not be included as factual in the article. Established textbooks such as Rhoades and Bell: Medical Physiology and BRS Physiology, which was already cited, say that Ca2+ is not reabsorbed in the kidney. The article cited is useful but by no means evidence of a complete contradiction of knowledge which has already been established. I've never changed a wikipedia article so I'll leave that to more experienced users, but it should be made clear in the article that although recent research may be in contradiction, when a med student takes their board exam, the kidney will DECREASE reabsorption of Ca2+ in response to calcitonin.

"In the kidneys, CT decreases the tubular reabsorption of calcium and phosphate. This leads to an increase in urinary excretion of both calcium and phosphate and, ultimately, to decreased levels of both ions in the plasma." from Rhoades and Bell Medical Physiology 2009

--72.88.239.221 (talk) 05:18, 31 March 2011 (UTC) Must agree with the above. Numerous current medical texts (Martini and Nath: Anatomy and physiology 2009; Rhoades and Bell: Medical Physiology 2009) maintain the traditional view that Calcitonin effects an increase in renal Ca++ excretion. It should be noted that both the Rhoades text, as well as Marieb/Hoehn (Human Anatomy and Physiology 2010) stress that the influence of Calcitonin on Ca++ homeostasis appears to be minor, especially with regard to renal reabsorption. Wiki article should be revised to reflect scientific consensus and current medical practice, rather than outdated fringe research. — Preceding unsigned comment added by 68.57.177.106 (talk) 15:54, 10 July 2011 (UTC)
