Brain accumulation of Hg from Thimerosal

[Guest guest]

The findings on brain accumulation from ethylmercury cited by Dr.

are the same as that found in a recent NIH-sponsored

primate study At equivalent doses, more Hg accumulates in brain

from the thimerosal due to its rapid conversion to inorganic

mercury, which, unlike methyl, cannot easily leave the CNS.

Scientists applaud move away from use of mercury

By Highfield, Science Editor

/(Filed: 10/08/2004)/

Scientists searching for a link between mercury and damage to the

developing brain welcomed yesterday's decision to remove the

_mercury-based preservative from childhood vaccines_

<http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2002/06/23/nmmr23.xml>.

Dr Salisbury, the head of immunisations at the Department of

Health, said the decision had nothing to do with concerns over a

link between the preservative thiomersal and autism.

But the reality is that the effects of the preservative are not

fully understood, according to a British professor who has

discovered that thiomersal accumulates and changes in the brain.

Prof Graham , of the University of Saskatchewan in

Saskatoon, Canada, is studying the fate of mercury in the body,

since the toxicity of organic compounds of this metal critically

depends on their molecular form and other factors, such as the

presence of selenium.

Advances in x-ray technology have enabled Prof 's team to

collect information that has eluded scientists in the past and it

is now studying the transformation of thiomersal (called

thimerosal in America) in the body.

Prof stressed that his findings are preliminary but

" indicate that mercury administered to rabbits as thimerosal does

accumulate in the brain in a relatively short time " . Thiomersal is

taken up in " about an hour " and is chemically modified, though he

would not be more specific because the work has not been published.

However, " it is a very good thing that it is coming out " .He said:

" It shocked me when I found out it is in vaccines. If you wanted

to chose something to put into a vaccine, and you were doing it

fresh, thiomersal would be the last thing.

" It is known to be neurotoxic and would never get approval for

drug use these days. It is only because it has been 'grandfathered

in' since the 1930s that it is in use at all.

" I made sure my kids did not get mercury in their vaccines and,

when my wife was pregnant, she did not have flu shots. Pregnant

women who receive the flu vaccine get a great big dose of

thiomersal and it is pretty well established where that will end

up - in the brain of the foetus or the kidney. "

He would " not be surprised " if there is a link with autism.In the

journal Molecular Psychiatry, a mechanism linking the preservative

to such developmental disorders has been set out by Prof

Deth of Northeastern University and colleagues.

Despite the reasons given for its removal by the Department of

Health, the move will decrease the risk of developmental

disorders, Prof Deth said yesterday.

Hi Sallie,

You said the ethylmercury cannot easily leave the cns........but does it

eventually?And using what product,natural agent or drug?Are the products

used the same as for methymercury?How long does it take for ethylmercury

and how do we know its out?

One point I wish to make here is a couple weeks ago there was some discussion

and concern over the fact that the White House is aiding the drug companies in

liability claims using FDA approval as a reason to throw out claims.

It occurred to me that in the case of thimerosal claims the argument is moot in

that the FDA to my knowledge, still has not established an ethylmercury

standard. Unless something has happened that I don't know about they are still

" borrowing " the methylmercury standard.

The FDA approval argument in order to dismiss vaccine injury claims or future

liability does not hold water until they get off their duffs and establish an

ethylmercury standard, IMHO.

Not until you chelate it with ALA (at least once it is converted to

inorganic mercury).

Neither ethlymercury nor methylmercury last long in your body. They

are metabolically converted to inorganic mercury within a few months.
