Abstract

Parkinson's disease (PD) is a neurological disorder originated from the death of dopaminergic neurons in the midbrain. Evidences showed that oxidative and nitrosative stress play a central role in neurodegeneration. In this study, we examine the neuroprotective effects of EBN (20 mg/kg and 100 mg/kg) in 6-hydroxydopamine (6-OHDA)-treated C57BL/6J mice. Twenty eight days of EBN oral administration greatly improved locomotor activity of PD mice in terms of travel distance and balancing. EBN also protected dopaminergic neuron against 6-OHDA in the substantia nigra. EBN reversed the reduction in the expression of antioxidant enzyme glutathione peroxidase 1 and the increased microglia activation in PD mice. Our results also showed that EBN effectively reduced 6-OHDA-induced nitric oxide formation and lipid peroxidation in SH-SY5Y cells. The data altogether indicates that EBN exerted neuroprotection through enhancement of antioxidant enzyme activity and the inhibition of microglia activation, nitric oxide formation and lipid peroxidation in PD model.
