Thank you try.

I have realized what is the difference of gold ions. Some medical and other deadly. And the difference was in charge. Deadly is the positive зарях ion, which contain the chemical salts of gold and the healing is negative charge, which becomes коллоидая piece of the solution . That's the information I finally realized that need to explore what the charge in the balance is a solution of + or -
Gold is a precious metal which exists in nature in two basic forms: metallic gold and gold salts, Metallic gold is called a noble metal because it does not react with other compounds easily and is usually inert. This is true for bulk gold, such as gold nuggets. If metallic gold is divided into fine particles with sizes ranging from one to one hundred billionths of a meter, metallic gold becomes colloidal and possesses new properties due to the large amount of gold atoms exposed at the surface of the particles. Colloidal gold possesses a negative charge at the surface of the particles and absorbs strongly to other molecules without changing their chemical and biological properties.
On the other hand, gold salts contain positively charged gold that forms strong chemical bond with other compounds normally present in the body and change their properties. This causes toxic reactions in the body because the immune system does not recognize these gold salts' complexes as self. (Schuhmann, D, et al: Adverse Immune Reactions to Gold. I. Chronic Treatment with an Au (I) Drug Sensitizes Mouse T Cells not to Au (1), but to Au (III) and Induces Autoantibody Formation, J. Immunol., 145:2132-2139, 1990.)
Gold salts are currently used in the treatment of rheumatoid arthritis (RA) with some success, but they cause side effects, sometimes severe enough to discontinue the gold salts: skin rashes, diarrhea, anemia, abnormalities in blood and urine tests. Because of those immune reactions, gold salts cease to be effective after 1-2 years and are rarely used in RA at the present time because of their toxicity. (Epstein, WV, et al: Effect of Parenterally Administered Gold Therapy on the Course of Adult Rheumatoid Arthritis, Ann. Int. Med., 114:437-444, 1991.)
