Abstract

Numerous studies indicating that natural plant sources and their active phytochemicals offer protection to the pathological processes related to the development of neurogenerative diseases including Parkinson’s disease (PD). In the present study, the neuro protective efficacy of dietary supplementation of walnut (6 %) for 28 days was examined in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) (i.p., 20 mg/kg body weight/day) for last four consecutive days. MPTP injection diminished the levels of GSH, dopamine and metabolites along with decreased activities of GPx and mitochondrial complex I. Further, the levels of TBARS and enzymatic antioxidants such as SOD and catalase, MAO-B activities were enhanced by MPTP treatment. Behavioral deficits and lowered TH expression are also proved MPTP induced neurotoxicity. Dietary supplementation of walnut attenuated MPTP-induced impairment in PD mice might be by its MAO-B inhibitory, antioxidant and mitochondrial protective actions. To find out the exact mechanism of action walnut on PD mice warrants further extensive studies.
