ABSTRACT
AIM:
To investigate the effects of cordycepin on the motor and cognition in Parkinson disease mice induced by 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP).METHODS:
C57BL/6 mice were intraperitoneally injected with MPTP at a dose of 30 mg/kg daily for consecutive 8 d to establish the model of Parkinson disease.HE staining was used to observe the cell number in the substantia nigra pars compacta (SNpc) from the mice.Western blot was used to detect the protein level of tyrosine hydroxylase (TH) in substantia nigra (SN).The effects of cordycepin on the motor, emotional change and cognitive behavior of the Parkinson disease mice were examined by open-field test (OFT) , spontaneous alternating behavior (SAB) and water maze test (WMT) , respectively.RESULTS:
Cordycepin significantly reduced the apoptosis of cells in SNpc and reversed the decrease in the expression of TH in SN induced by MPTP (P<0.05).Furthermore, cordycepin was able to improve the average speed in OFT (P<0.05) , and increased the total number of arm entry and the accuracy in SAB (P<0.05) , but had no obvious effect on the latency in WMT.CONCLU-SIONCordycepin is capable of attenuating the impairments of motor and explorative ability in the early stage of Parkinson disease mice, but does not alter the cognitive dysfunction.
