Neuroprotective Effects of Germinated Brown Rice in Rotenone-Induced Parkinson's-Like Disease Rats.

The effects of germinated brown rice (GBR) on the motor deficits and the dopaminergic (DA) cell death were investigated in Parkinson's-like disease (PD) rats. Reactive oxidative species generated by chronic subcutaneous injection of rotenone (RT) lead to neuronal apoptosis particularly in the nigrostriatal DA system and produce many features of PD, bradykinesis, postural instability and rigidity. In this study, 4-phenylbutyric acid (4-PBA), previously reported to inhibit RT-induced DA cell death, was used as the positive control.
