Abstract:

OBJECTIVE: To investigate the oil from the spores of ganoderma lucidum, a rare Chinese herb, on the behaviors and pathological changes in the substantia nigra pars compacta (SNpc) in mouse models of Parkinson's disease (PD) induced by MPTP. METHODS: C57BL mice were divided into 3 groups, and the ganoderma spores oil + MPTP group were treated with ganoderma spores oil for 8 days, together with subcutaneous injection of MPTP (30 mg/kg) starting on the third day for 6 days; MPTP group were pretreated with normal saline before subcutaneous MPTP injection, and the normal control group received pretreatment with normal saline before subcutaneous normal saline injection. The behavioral changes of the mice in different groups were observed by pole test, dopamine and its metabolic products in the striatum determined by HPLC, tyrosine hydroxylase (TH) positive cells detected by immunofluorescence method, and expression of TH protein by Western blotting. RESULTS: The mice in the ganoderma spores oil + MPTP group presented significantly less involuntary movement of the limbs in the pole test than the mice in MPTP group. The levels of dopamine and DOPAC in the striatum of ganoderma spores oil-treated mice were increased as compared with those in MPTP group. The number of surviving TH-positive neurons in SNpc of mice in ganoderma spores oil + MPTP group was significantly greater than that in MPTP group, with also significantly increased TH protein expression. CONCLUSION: Ganoderma spores oil has neuroprotective effect for preventing doparminergic neuron from impairment by MPTP.
