Here is the list of mercury related research with a sentence of explanation. You will see that it
lays out a very clear picture of exposure, intake, body burden, distribution and
pathophysiology related to mercury released from set dental amalgam. The authors email was
provided when I had their address. Almost all of the authors are available if needed except
Michael Ziff who has passed away.

First they measured the intra-oral levels of mercury generated using a standardized technique.

after 90 minutes.

expose experimental subjects to excessive levels of mercury so our work turned to animals.

The German Department of Health had banned amalgam use in women and children following
the International Academy of Oral Medicine and Toxicology in Düsseldorf in 1992. Members of
the dental profession protested that they hadn’t been given an opportunity to present their
evidence of safety. This conference consisted of 25 presenters and 2 moderators who are
experts in mercury. The peer reviewed conclusions supported the German ban on exposure of
children and women of childbearing age to mercury from amalgam.

The video from this research shows that the introduction of 100 times less mercury than found
in the cerebral spinal fluid of amalgam bearers into a cell culture of growing nerve cells
immediately halts growth and produces neurofibrillar tangles similar to those seen in
WHO Environmental Health Criteria 118: Inorganic Mercury. World Health Organization,
The WHO has determined that dental amalgam is the predominant source of human exposure
human daily dose of mercury from various sources is:
Dental amalgam = 3.0-17.0µg/day (Hg vapor)
Fish and Seafood = 2.3 µg/day (methylmercury)
Other food = 0.3 µg/day(inorganic Hg)
Air & Water = Negligible traces
“A specific no-observed–effect level (NOEL) cannot be established”
In 1991 Dr. Murray Vimy our founder participated in the WHO assessment of the daily dose
received from amalgam in Genoa, Italy. The conclusions of this expert ad hoc committee are
now in the Criteria document 118. Email: Murray Vimy <firstname.lastname@example.org>
Inhalation of mercury vapor (Hg0) inhibits binding of GTP to rat brain tubulin, thereby inhibiting tubulin polymerization into microtubules. A similar molecular lesion has also been observed in 80% of brains from patients with Alzheimer disease (AD) compared to age-matched controls. However the precise site and mode of action of Hg ions remain illusive. Therefore, the present study examined whether Hg ions could affect membrane dynamics of neurite growth cone morphology and behavior. Since tubulin is a highly conserved cytoskeletal protein in both vertebrates and invertebrates, we hypothesized that growth cones from animal species could be highly susceptible to Hg ions. To test this possibility, the identified, large Pedal A (PeA) neurons from the central ring ganglia of the snail Lymnaea stagnalis were cultured for 48 h in 2 ml brain conditioned medium (CM). Following neurite outgrowth, metal chloride solution (2 μl) of Hg, Al, Pb, Cd, or Mn (10-7 M) was pressure applied directly onto individual growth cones. Time-lapse images with inverted microscopy were acquired prior to, during, and after the metal ion exposure. We demonstrate that Hg ions markedly disrupted membrane structure and linear growth rates of imaged neurites in 77% of all nerve growth cones. When growth cones were stained with antibodies specific for both tubulin and actin, it was the tubulin/microtubule structure that disintegrated following Hg exposure. Moreover, some denuded neurites were also observed to form neurofibrillary aggregates. In contrast, growth cone exposure to other metal ions did not effect growth cone morphology, nor was their motility rate compromised. To determine the growth suppressive effects of Hg ions on neuronal sprouting, cells were cultured either in the presence or absence of Hg ions. We found that in the presence of Hg ions, neuronal somata failed to sprout, whereas other metalic ions did not effect growth patterns of cultured PeA cells. We conclude that this visual evidence and previous biochemical data strongly implicate Hg as a potential etiological factor in neurodegeneration.
