Eco-friendly Microwave Synthesis of Gold Nanoparticles for Attenuation of Brain Dysfunction in Diabetic Rats

In this current work, gold nanoparticles (AuNPs) were used to attenuate the brain dysfunction in experimental model of diabetes. Microwave radiation technique was utilized in the production of AuNPs. Afterward, 40 male albino rats were consumed in this study and divided into five groups: control, diabetic, diabetic administered only dextran, diabetic administered AuNPs in a dose of 1 mg/kg body weight in aqueous solution/day, and diabetic administered AuNPs in a dose of 2 mg/kg body weight in aqueous solution/day. In addition, brain neurotransmitters and cholinesterase activity were also evaluated. Results: In diabetic group, diabetes complications were appeared in elevation of oxidative stress parameters and pro inflammatory markers, in addition to disturbances of neurotransmitters as well as cholinesterase activity, however in treated groups, AuNPs significantly controlled all these hazardous induced by induction of diabetes. In conclusion, AuNPs appeared as a promising agent, that has the ability to augment neuronal damage and brain dysfunction appeared during diabetes mellitus. Additionally, the high dose (2 mg/kg body weight) appeared more potent than the lower dose (1 mg/kg body weight) in attenuating diabetic complications during experimental diabetes.
