  IAN: I found and acquired another study on the effect
  of mercury vapor on brain tubulin, which is what the
  last study I posted was exploring and it found that
  mercury vapor (Hg0) acted like Alzheimer's disease
  (AD) at levels one could expect if you have many
  "silver" amalgam fillings. That abstract is here:

  Neurotoxicology 1997;18(2):315-24

  The new study, a review of studies, has no abstract
  on-line, but I got it at the National Library o Meds.

  Met Ions Biol Syst 1997;34:461-78

  This study reports that mercury prechelated with EDTA,
  EGTA, or glutamine "selectively abolishes tubulin-GTP
  interactions in normal human brain tissues." Apparently
  mercury can become chelated to glutamine in the brain.
  Such diminished GTP interactions are a biomarker of AD
  and is the same harmful effect found in the first study.

  The study concludes: "The data found in the references
  used in this presentation demonstrate that exposure to
  mercury causes the same aberrancy in non-AD brain and
  rat brain as observed in AD brain. These results do not
  prove that mercury causes AD. They do strongly suggest
  that exposure to mercury, and especially mercury vapor,
  would exacerbate the condition clinically defined as AD.
  Therefore, individuals with family histories indicating
  a genetic predisposition toward AD should avoid any
  exposure to mercury." I've never that important info
  anywhere except as resulting from my PubMed searches.
  One constantly finds info there you don't get elsewhere.
  The American Dental Association continues to claim that
  there is NO evidence of any risk associated with amalgam.
