Effects of Achyranthis bidentatae-Cynanchum otophyllum on oxidative stress of cerebral tissue in Parkinson’s disease mice with syndrome of hyperactivity of liver-Yang
as core couplet medicinals of Zhengan xifeng decoction on oxidative stress of cerebral tissue in Parkinson’s disease (PD) mice with syndrome of hyperactivity of liver-Yang.
METHODS
2
C57BL/6 mice were randomly divided into normal control group, model group, Zhengan xifeng decoction group,
A. bidntatae
group,
C. otophyllum
group and couplet medicinals of
A. bidentatae-C. otophyllum
group, with 10 mice in each group. PD model of hyperactivity of liver-Yang was established by intragastric administration of
Aconitum carmichaelii
decoction(4 g/kg) and intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (25 mg/kg).The behavioral changes and ultrastructure of substantia nigra neurons in mice were observed. The expressions of tyrosine hydroxylase (TH) positive neurons in substantia nigra were detected.The expressions of total antioxidant capacity (T-AOC),superoxide dismutase (SOD) and malondialdehyde (MDA) in substantia nigra as well as mRNA and protein expressions of nuclear factor-erythroid 2-related factor 2 (Nrf2), thioredoxin reductase 1 (Trxr1), thioredoxin interacting protein (Txnip) were also determined.
RESULTS
2
Compared with model group, PD behavior and ultrastructure of substantia nigra neurons were all improved in administration groups.The expressions of TH positive neurons, T-AOC (except for
C.otophyllum
group) and SOD (except for
C.otophyllum
group), mRNA relative expression and protein expression levels of Nrf2 and Trxr1 were all increased significantly; the expression of MDA (except for
C.otophyllum
group) and mRNA relative expression and protein expression levels of Txnip were all decreased significantly (
P
<0.05). Intervention effect of couplet medicinals of
A. bidentatae-C. otophyllum
group was better than that of
A.bidntatae
group and
C. otophyllum
group (
P
<0.05), and the effect was similar to that of Zhengan xifeng decoction group (
P
>0.05).
CONCLUSIONS
2
The couplet medicinals of
A. bidentatae-C. otophyllum
can inhibit the level of oxidative stress in the cerebral tissue of PD mice with hyperactivity of liver-Yang by targeting Nrf2, and play a protective role on the brain neurons. Its effect is better than that of
A.bidntatae
and
C.otophyllum
, and it plays the same role as that of the formula in tonifying the kidney, softening the liver and suppressing the Yang.
