Hi Silver List, Re Silver and non-neurotoxicity:
Below is an abstract of an vitro (test-tube) trial in which Colloidal Silver showed protective against the type of free radical damage (Reactive Oxygen Species) caused by chemotherapy and observed in some forms of neuro-degenerative illnesses. The Brain Cells cultured where Astrocytes. 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.
