Abstract:
Objective To study the influences of Jianpizhidong decoction(JPZDD) on bilateral striatal amino acid neurotransmitters in mice with Tourette Syndrome (TS) disease and discuss the mechanism of JPZDD.Methods Thirty mice were injected 3,3-iminodipropionitrile (IDPN) with 350 mg· kg-1 once a day for 7 consecutive days except ten mice of the blank control group which were injected with saline.TS mice were randomly divided into three groups:TS model group,JPZDD group (the Chinese herbal group),Tiapride group (the western medicine group).The TS model group and the blank control group were gavaged with saline(0.9％)at 20 ml ·Kg-1,the Tiapride group with Tiapride at 50 mg · kg-1,and JPZDD group with JPZDD at 20 g · kg-1,respectively,once a day for six weeks.Then behavioral recordings were conducted,and the content of glumatic acid (Glu) and γ-aminobutyric acid (GABA) in the bilateral striatum of the mice were detected by using HPLC.Results Behavioral recording indicated that there were significant differences in the Chinese herbal group and the Tiapride group before(1.90 ± 1.80,2.05 ± 1.40) and after(1.15 ± 1.67,1.00 ± 1.08) treatment (P ＜ 0.05).The content of Glu and GABA in TS model group (1858.33 ± 203.00,261.24 ± 47.31) and Tiapride group (1744.53 ± 234.01,258.57 ± 57.64) were higher compared with the blank control group (P ＜ 0.05),and the content of Glu in JPZDD was significantly higher than that in TS model group.There was no statistical difference between other groups(P＞0.05).The ratio of Glu and GABA were lower in the JPZDD,the Tiapride and the model groups than that in the blank control group,but there were no statistical differences between these groups (P＞ 0.05).Conclusion JPZDD can regulate the content of Glu and GABA in the striatum,and keep the dynamic equilibrium,which might be its pharmacodynamic mechanisms for treating TS.
