Guest guest Posted April 19, 2006 Report Share Posted April 19, 2006 This important peer reviewed article may help to illuminate why we are seeing higher levels of metals excretion in the urine during antiviral therapy, and why we sometimes observe the mobile rashes that change color and intensity (possibly metals rashes). - Stan ------------- <Article forwarded by Binstock> Biol Trace Elem Res. 2005 Winter;108(1-3):215-24. Related Articles, Links Selenium and mercury are redistributed to the brain during viral infection in mice. Ilback NG, Lindh U, Minqin R, Friman G, Watt F. Section of Infectious Diseases, Department of Medical Sciences, Uppsala University Hospital, Uppsala, Sweden. As part of the general host response to coxsackievirus B3 (CB3) infection, the concentration of essential and nonessential trace elements changes in different target organs of the infection. Essential (e.g., Se) and nonessential (e.g., Hg) trace elements are known to interact and affect inflammatory tissue lesions induced by CB3 infection. However, it is unknown whether these changes involve the brain. In the present study, the brain Hg and Se contents were measured through inductively coupled plasma-mass spectrometry and their distribution investigated by means of nuclear microscopy in the early phase (d 3) of CB3 infection in normally fed female Balb/c mice. Because of the infection, the concentration of Hg (4.07 +/- 0.46 ng/g wet wt) and Se (340 +/- 16 ng/g wet wt) in the brain increased twofold for Hg (8.77 +/- 1.65 ng/g wet wt, p < 0.05) and by 36% for Se (461 +/- 150 ng/g wet wt, ns). Nuclear microscopy of brain sections from mice having elevated Se and Hg concentrations failed to find localized levels of the elements high enough to make detection possible, indicating approximately homogeneous tissue distribution. Although the pathophysiological interpretation of these findings requires further research, the increase of Hg in the brain during infection might have an influence on the pathogenesis of the disease.

Guest guest Posted April 19, 2006 Report Share Posted April 19, 2006 So is this extra selenium in the brain a bad thing? Should one not give too much selenium during viral treatments? Boyd Haley had done a study about how selenium binds with mercury in the brain and renders it inert. It didn't quite answer the question of whether this was a good thing or a bad thing. The downside might be, how do you get this mercury-selenium combo to get out of the brain. Okay I looked in my files and found a parent on CK2 who had contacted Boyd Haley and had said that it was okay to share this information. Not sure whether he meant only the CK2 list or any list, I am removing his name for privacy. If he is on here anyway, he could comment on it. Gayatri PS Sorry about the formatting, too much to clean up! All, A while back, Dr. McCandless posted (on CSB) that Dr. Boyd Haley recommended not to give Selenium during chelation days as it binds mercury (thus preventing excretion). We give Selenium to our boys in drop form and in Picmins during chelation days because our boys are low in Selenium. So, this statement peaked my interest and made me wonder if the low urine Hg output we see could be caused by giving Selenium during chelation days. Below is a series of emails and responses between Dr Haley and I. He was gracious enough to clarify this and I feel that it is important enough to share so everyone can make their own decision on when to administer Selenium. Dr Haley is fine with me sharing this information. In addition, I thought I would ask Dr. Haley about the new chelator he is working on. He was also nice enough to give me an update which is at the bottom of this post.

The information indicated that you recommended that selenium NOT be given during chelation days, as it keeps the mercury tied up so it is non-toxic to the body and when we chelate we want the mercury to be available for removal. So giving it all the time might slow down mercury excretion. I think I understand why this is so, but it really caught my attention as I know that many many parents actually give Selenium during chelation days. If I am understanding this correctly, then many parents need to know to stop giving Selenium during chelation. Would you mind elaborating on this? My concern is that many parents may not be seeing full mercury excretion because of what you are indicating. All of the parents I know on the various forums have a great deal of respect for you and this could help us in our quest to chelate mercury. Sincerely, From: Boyd E.

Therefore, if both Se2- and DMSA are in the blood at the same time the Hg2+ will preferentially be bound by the Se2- and will not be Hg2+ excreted in the urine and one will end up with a lower excretion reading if they are using urine as the test material, which is the normal way it is done. I don't think having Se2- in the blood will do any damage, it may even help to remove the toxic mercury from the proteins being inhibited. But it will likely give a lower urine mercury reading on a DMPS or DMSA challenge test. HgSe is not rapidly removed from the body, but it is of very low, if any, toxicity.

I thought that if Selenium bound Mercury during chelation then the Mercury would stay internal (instead of being swept) and cause more damage to the CNS. But, if the Selenium is rendering the Mercury inactive then I guess it would not cause damage, although it would not be excreted. If the latter is true, then would the mercury leave your system during OFF days of chelation. Can you please elaborate as this may seem like a small point, but I assure you it is important for parents to know if they should stop giving Selenium during chelation ON days, which is what I gather from this. Not that it is harmful, but that it impedes chelation progress. Also, may I share your response on the chelation parent forum please? From: Boyd E.

I don't keep my opinions on mercury chemistry/biochemistry secret from anyone. It is well known that mercury miners have very high levels of mercury in their body tissues, levels that would make more normal individuals quite sick, yet they appear relatively healthy. It was also determined that for each unit of mercury they retain they also retain an equal unit of selenium from their diet. Therefore, they are retaining mercury selenide (HgSe) at high levels and this compound appears not to be toxic because the typing up of the Hg2+ with Se2- keeping the Hg2+ from reacting with and inhibiting enzymes in the body. This does not mean that it is good to have HgSe in the body and that there are no negative effects from this build up, but HgSe is much less toxic than Hg2+. I don't think that it is known how or if HgSe is excreted by the body. It is probably dependent on where the HgSe forms. If it is formed in the blood it might be excreted, but if it is formed in the brain it is likely to be there for a long time. Finally, I don't know the answer as to whether it is good or bad to give selenium on days of chelation, but it seems likely to me that the presence of Se2- in the blood would decrease the binding and excretion of mercury in the urine by DMPS or DMSA. However, the presence of Se2- in the blood could increase the fecal excretion of Hg, but I do not know of any study that addresses this issue. > > This important peer reviewed article may help to illuminate why we are seeing higher > levels of metals excretion in the urine during antiviral therapy, and why we sometimes > observe the mobile rashes that change color and intensity (possibly metals rashes). > > - Stan > > ------------- > > <Article forwarded by Binstock> > > Biol Trace Elem Res. 2005 Winter;108(1-3):215-24.
