Antioxidative Activity of Platinum Nanocolloid and Its Protective Effect Against Chemical-Induced Hepatic Cellular Damage

J Nanosci Nanotechnol. 2015 Aug;15(8):5571-6. doi: 10.1166/jnn.2015.10468.


Oxidative stress, a major cause of cellular injuries, is closely associated with a variety of chronic diseases such as cancer, liver diseases, degenerative brain disease and aging. In this study, we investigated antioxidant properties of platinum nanocolloid (PNC) against various oxidative stress conditions in vitro/in vivo by treating PNC on liver cell or tissue. Antioxidant activities of the PNC were determined by measuring quenching capacity on reactive oxygen species and its protective action against hydrogen peroxide or CCl4-induced oxidative cellular damage in HepG2 cell or liver tissue of mice. In vitro study, PNC markedly suppressed the production H2O2, ·OH, α,α-diphenyl-β-picrylhydrazyl radical and nitric oxide in a dose-dependent manner. PNC also inhibited hydrogen peroxide-induced oxidative cellular damage in HepG2 hepatocytes. In vivo study with mice, PNC reduced hepatic lipid peroxidation and CCl4 induced toxicity. Our results support that platinum nanocolloid has antioxidant activities and protects hepatic cellular oxidative damage. Thus platinum nanocolloid may have a potential to be used as an antioxidant supplement.
