Abstract:
AIM:To observe the intervention ef-fect of Chinese medicine Kangzhen Zhijing spas-modic decoction Ⅰ on the progression of Parkin-son's disease in mice,and to explore the potential mechanism of neuroprotection.METHODS:Thirty-six C57BL/6 mice were randomly divided into con-trol group,model group,drug group and positive drug group.In the model group,the drug adminis-tration group and the positive drug group,1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)(30 mg/kg)was injected intraperitoneally for 5 days to establish the mouse model.The control group was given the same amount of normal saline,the drug administration group was given 1.25 mg/kg,2.5 mg/kg,5 mg/kg dose of Chinese medicine Kang-zhen Zhijing spasmodic DecoctionⅠby gavage,and the positive drug group was given 75 mg/kg Madopar by gavage.Behavioral tests were per-formed on the second day after the administration in each group.Immunopositive cells of Tyrosine hy-droxylase(TH),Amyloid precursor protein(APP),α-synuclein(α-syn)and solute carrier family 6 mem-ber 11(SLC6A11)were detected by immunohisto-chemistry.The protein expressions of TH,APP,α-syn and SLC6A11 in each group were detected by Western blot.RESULTS:It could significantly im-prove the weight loss of mice in the model group,alleviate the decline of autonomic activity in open field test and the decline of coordination ability in pole test and suspension test.In the reverse immu-nohistochemistry and Western Blot experiments,the expressions of TH and SLC6A11 in the brain of the Parkinson's model group were significantly de-creased,and the expressions of APP and α-syn were significantly increased.CONCLUSION:Kang-zhen Zhijing spasmodic decoctionⅠcan significantly improve the behavioral performance of Parkinson's disease mice and effectively improve the reduction of neuronal transmitters.
