Astrocytes are star-shaped glial cells in the brain and spinal cord. They perform many functions, including biochemical support of endothelial cells which form the blood-brain barrier, the provision of nutrients to the nervous tissue (neurons), and a principal role in the repair and scarring process in the brain - - The study show: - - - Colloidal Silver was non-toxic to Astrocytes and showed Anti-oxidant properties. - - Colloidal Silver did not protect against H2O2 free radical damage, which in my opinion is a positive finding, Colloidal Silver does not interfere H2O2 which is used by the Immune System. - - From the Abstract available online at Pubmed.com - - - Central Research Institute, Natural F&P Co., LTD, - Chunchon, South Korea. [email protected] - - One major pathogenesis in degenerative disorders of the - central nervous system (CNS), including Alzheimer's disease, Parkinson's - disease, amyotrophic lateral sclerosis, and ischemia, is the oxidative stress - induced by reactive oxygen species (ROS). The present study investigated the - protective effect of colloidal silver, which is widely marketed as a dietary - supplement for diseases like diabetes, AIDS, cancer, and various infections, - upon the oxidative brain damage induced by H(2)O(2) or naphthazarin treatment. - LDH release from primary cultured astrocytes was enhanced by naphthazarin - treatment, and this elevation of the LDH concentration in medium was blocked by - colloidal silver treatment. However, hydrogen peroxide was little affected by - the colloidal silver. Fluorescence of DCF (peroxides) increased in astrocytes - incubated with hydrogen peroxide or naphthazarin compared to the control. When - exposed to naphthazarin-induced cells, ROS formation appeared to be reduced by - colloidal silver. However, intracellular ROS formation in hydrogen - peroxide-treated cells slightly reduced by colloidal silver. These results - suggest that colloidal silver has a protective activity against the oxidative - stress induced by naphthazarin, but not by hydrogen peroxide. - - - Kim DW, Hong GH, Lee HH, Choi SH, Chun BG, Won CK, Hwang IK, Won MH. - - Effect of colloidal silver against the cytotoxicity of hydrogen peroxide and naphthazarin on primary cultured cortical astrocytes. - - Int J Neurosci. 2007 Mar;117(3):387-400. - - Best Regards, - - Steve Foss -

It sounds like a bunch of crap. Or are they talking about nanoparticles smaller than ionic silver?
