title: Protective effect of GSH on PD model induced by 6-OHDA in vitro.
abstract: To study the effects of 6-hydroxydopamine (6-OHDA) and reduced glutathione (GSH) on the nigral dopaminergic neurons in brain slices in vitro, immolunohistochemical technique was used to observe the changes of TH-stained neurons, including cell bodies and the dendrites, in the substantia nigra (SN) of midbrain slices of rats after incubation for 1 h in the presence of GSH 15 min before and during the period of incubation with 6-OHDA. The results showed that cell bodies remained intact but dendrites were fragmented and truncated after treatment with 6-OHDA. The antioxidant GSH alone did not significantly affect the dendrites of SN neurons but prevented 6-O-HDA-induced damage of dendrites. It was concluded that glutathione may prevent 6-OHDA-induced dopaminergic neurodegeneration and play a protective role in dopaminergic neurons.
