Mystery Solved: Gold's Power Against Autoimmune Diseases Defined" from http://www.bio.com/newsfeatures/news...l?cid=17500004

02/27/06 -- Gold compounds have been used for the treatment of rheumatoid arthritis and other autoimmune diseases for more than 75 years, but until now, how the metals work has been a mystery. Harvard Medical School researchers report in the Feb. 27 issue of Nature Chemical Biology that special forms of gold, platinum, and other classes of medicinal metals work by stripping bacteria and virus particles from the grasp of a key immune system protein.

Effect of Colloidal Metallic Gold
on Cognitive Functions: A Pilot Study

Abstract:
In order to evaluate the effect of colloidal metallic gold on cognitive functions, the revised Wechsler Intelligence scales battery of tests (WAIS-R) was administered to 5 subjects aged 15 to 45 years, before, after 4 weeks on colloidal gold at 30 mg/day and again 1 to 3 months off the gold preparation. The WAIS-R total scores (I.Q) were calculated by adding the sum of the verbal test scores to the sum of the performance scores. After 4 weeks on colloidal gold, there was a 20% increase in I.Q scores with mean + SE of 112.8 + 2.3 pre gold and 137 + 3.8, post gold (p <0.005). Both the performance and verbal test scores contributed equally to this increase in I.Q scores. The effect of the colloidal gold persisted in 3 subjects after 1 to 2 month off gold, where as in 2 subjects who took the tests 3 months after stopping the gold , I.Q scores were down to baseline levels.
