Abstract
This study investigated the neuroprotective potential of silver nanoparticles (AgNPs) synthesized using Diosmin against rotenone-induced behavioral and motor impairments in a male Wistar rat model of Parkinson’s disease (PD). Thirty-six male Wistar rats were randomly divided into six groups of six animals each. Group I served as the vehicle control, while Group II received intraperitoneal rotenone (0.5 mg/kg body weight). Groups III, IV, and V were co-treated with rotenone and orally administered biosynthesized AgNPs at doses of 5, 10, and 20 mg/kg, respectively, for 60 days. Group VI received AgNPs alone (20 mg/kg). Motor and behavioral performance was assessed using open field, rotarod, hanging wire, and narrow beam walking tests, among others. Rats treated with rotenone exhibited significant behavioral deficits and impaired motor coordination compared with controls (p < 0.001). Co-administration of Diosmin-based AgNPs markedly improved locomotor activity, balance, and muscle strength, restoring performance parameters close to normal levels. These findings suggest that diosmin-mediated AgNPs could serve as promising therapeutic agents for managing Parkinsonian neurodegeneration
