Dose-dependent effect in the inhibition of oxidative stress and anticlastogenic potential of ginger in STZ induced diabetic rats
2012
Ginger is an important medicinal herb has numerous bioactive components and is used in the management, control and/or treatment of diseases including diabetes mellitus. The present study was undertaken to see the dose–response effect of ginger and evaluate the possible protective effects of dietary ginger on oxidative stress and genotoxicity induced by streptozotocin (STZ) diabetic rats. Inbred male Wistar/NIN rats of 8–9weeks old were treated with 30mg/kg of STZ. Rats were divided into different groups of control, diabetic non-treated, and diabetic treated with ginger powder at 0.5%, 1% and 5% respectively. After feeding for a month, blood and tissues were collected to see the effect of ginger on antioxidant status, DNA damage and bone marrow genotoxicity. In this study ginger exerted a protective effect against STZ-induced diabetes by modulating antioxidant enzymes and glutathione and down regulating lipid and protein oxidation and inhibition in genotoxicity in a dose–response manner.
