Abstract :

We aimed to evaluate the antioxidant effect of silver nanoparticles on oxidative stress in adult female of Wistar rats. In this experimental study, 50 adult female of Wistar rats were randomly divided into 5 groups. The control group (no treatment), sham group (0.2 mg/kg physiology serum), experimental group 1 (50 mg/kg isoniazid), experimental group 2 (50 mg/kg isoniazid and 0.25 mg/kg silver nanoparticles) and the experimental group 3 (50 mg/kg isoniazid and 0.5 mg/kg silver nanoparticles) were given. All injections were prescribed for 15 d and isoniazid and silver nanoparticles were injected in gavage and intraperitoneally, respectively. Then all animals were anesthetized and blooded. In the end, the data were examined by ANOVA test at a significance level of P<0.05 using SPSS software. Isoniazid increases nitric oxide, reduces glutathione peroxidase activity and total antioxidant capacity. While treating the animals with silver nanoparticles reduced the side effects of oxidant-induced by isoniazid, with decreasing nitric oxide, increased glutathione peroxidase and total antioxidant capacity by reducing nitric oxide production and increasing glutathione peroxidase activity oxidative, silver nanoparticle prevent from oxidative damages and the destruction of red blood cell (RBC) membrane. In other words, the tests showed the antioxidant role of silver nanoparticles as well.
