NEW RESEARCH CONNECTS MERCURY TO ALZHEIMER'S DISEASE!
Research conducted at the University of Calgary Faculty of Medicine has
demonstrated that trace amounts of mercury can cause the type of damage
to nerves that is characteristic of the damage found in Alzheimer's
Disease.
The level of mercury exposure is consistent with those levels found in
humans with mercury/silver amalgam dental fillings.
The exposure to mercury caused the formation of "neurofibrillar
tangles,"
which are one of the two diagnostic markers for Alzheimer's Disease.
The scientists found that other metals, including aluminum, did not
cause
the damage.
Previous research has shown that mercury can cause the formation of the
other Alzheimer's Disease diagnostic marker, "amyloid plaques."
The research, published in a peer-reviewed medical journal, is
accompanied
by a video visual presentation of the effect.
Utilizing digital time-lapse photography, this video shows rapid damage
to
the nerve cells after introduction of minute amounts of mercury.
Funding for this video was provided by the International Academy of
Oral Medicine and Toxicology (IAOMT).
SPECIAL NOTE: The University of Calgary has placed a copy of the video on
their site at:
BIOPROBE COMMENT: This study should remove all doubt regarding the role
that dental mercury from amalgam fillings plays in the development of
Alzheimer's Disease (AD).
Although the American Dental Association would like to have you
believe otherwise, science has clearly demonstrated that there is a
positive correlation between brain mercury levels and the number and
surfaces of "mercury/silver"
amalgam dental fillings.
The mercury levels that caused the devastating damage to nerve cells in
the above referenced study were 100 to 1000 times below those found in the
brains of people with "mercury/silver" amalgam dental fillings.
In 1997, researchers at the University of Calgary Medical School and
the
College of Pharmacy at the University of Kentucky clearly demonstrated
that exposing rats to the same levels of mercury vapor that can be released
from "mercury/silver" amalgam dental fillings caused the mercury to interact
with brain tubulin and disassemble microtubles that maintain neurite
structure.
The identical neurochemical lesion of similar or greater magnitude is
evident in Alzheimer brain homogenates from approximately 80% of
patients, when compared to human age-matched neurological controls.

In 2000, researchers at the Neurobiology Laboratory, Psychiatric
University Hospital in Basel, Switzerland using neuroblastoma cells exposed
to
mercury demonstrated an increase in production of amyloid protein that makes
up
the amyloid plaques as well as significantly increasing the phophorylation
of Tau protein. (J Neurochem 2000 Jan;74(1):231- 236)

There is plenty to read on all of the above subjects. You could take
a look at www.amalgam.org OR www.bioprobe.com OR
www.talkinternational.com -- or try a search engine. Among other
things, you could look for American Academy of Biological Dentistry,
Internation Academy of Oral Medicine and Toxicity, and Foundation for Toxic
Free Dentistry. Generally the topic of what materials are
best seems complex.
