<I>Bacopa monniera</I> Stabilized Silver Nanoparticles Attenuates Oxidative Stress Induced by Aluminum in Albino Mice

Abstract

In the recent years usage of nanomedicine plays a promising strategy in the improvement of medical treatment. The ecofriendly synthesized silver nanoparticles has introduced a new opportunity to increase the efficacy of drug by reducing its side effects. In the present study, we investigated the antioxidant property of Bacopa monniera stabilized silver nanoparticles against aluminum induced toxicity in albino mice. Forty male albino mice were randomly divided into five groups. First group was treated as control, second group received aluminum acetate (5 mg/kg b . w), third group received Bacopa monniera extract (5 mg/kg b . w), fourth group received BmSNPs (5 mg/kg b . w), fifth group received aluminum acetate plus BmSNPs. Exposure to aluminum acetate significantly increased lipid peroxidation levels with a significant decrease in the antioxidant enzymes such as superoxide dismutase, catalase and glutathione peroxidase activities in the brain, liver and kidney of mice. Degenerative changes were also observed in brain, liver and kidney of aluminum treated mice. No significant changes in the oxidative stress were observed in the Bacopa monniera and BmSNPs alone treated mice. Whereas, co-administration of BmSNPs to Al treated mice showed a significant decrease in lipid peroxidation levels with a significant increase of SOD, CAT and GPx indicating the antioxidant potential of nanoparticles and in counteracting Al induced oxidative stress and histological response in male albino mice. These findings clearly implicate that BmSNPs are able to eradicate the oxidative stress and prevent the tissue damage in aluminum exposed mice.

“…Aluminium-induced oxidative stress indicated by a significant increase in the lipid peroxidation levels and decrease of SOD, CAT and GPx was counteracted by the co-administration of B. monnieri stabilized silver nanoparticles (BmSNPs). These findings implicate that BmSNPs can eradicate oxidative stress and prevent tissue damage in aluminium exposed mice [85].…”

Zinc Oxide Nanoparticles Ameliorate Aluminum Chloride-Induced Hepato-Renal Oxidative Stress and Inflammation in Rats

“…Chronic administration of Al-induced changes in the morphological structure of glomeruli and proximal tubular cells and affected the levels of kidney function parameters [6]. Oxidative stress is an important mechanism involved in Al-induced hepato-renal toxicity, through enhanced lipid peroxidation, nitric oxide formation and depressed cellular glutathione [5,7].…”

Facile approach to synthesize magnesium oxide nanoparticles by using Clitoria ternatea—characterization and in vitro antioxidant studies

“…Due to their desired distribution, dispersion, sizes and shapes, the nanoparticles have numerous applications in human-day to day life, ranging from consumer goods to medicine Mahitha et al 2015;Mansee Thakur et al 2014). The main objective of this new field is to design and produce the multifunctional materials of nano scale range which are gearing the biological fields (Salata 2004;Nagarajan and Kuppusamy 2013) by making improvements in existing materials (Anamika Mubayi et al 2012;Geoffrey Ozin and Cademartiri 2009;Revell 2006).…”
