Objective To evaluate the expression level of glucose regulating protein 78(GRP78) in the model of Parkinson's disease(PD)induced by 6-Hydroxydopamine(6-OHDA) in PC12 cells.

Objective:To study the effect of glutathione (GSH), Ligustrazine and Salvia miltiorrhiza on dopamine (DA) and its metabolites of corpus striatum and DA neurons in rats injected with 6-OHDA.

Objective To investigate the possible neuroprotective effect of dopamine(DA) receptor agonist R-apomorphine(R-APO) on the 6-hydroxydopamine(6-OHDA)-induced rat model of Parkinson's disease.
