-ATPase
excitatory amino acid transporters(EAATs) and glutamate(Glu) in hippocampus of post-stroke spasticity rats
so as to explore the central mechanism in anti-spasticity. Methods In a total of 48 healthy SD rats
12 rats were randomly selected to be included into sham operation group
and the remaining rats were used to make a middle cerebral artery occlusion(MCAO) model using a suture method. On the 3+-ATPase

GB34(Hui-puncture at GB34) and GB34+GV20(Hui-puncture at GB34 and horizontal insertion at GV20) groups(n=12 rats in each group)
and the treatment was lasted for 7 conse-cutive days. The neurological symptoms and muscle tension score were observed with the Zea Longa score and modified Ashworth scale(MAS). The levels of Glu

-ATPase α1(ATP1α1) was detected by Western blot
the expression of ATP1α1 mRNA was detected by real-time PCR
and the expression of GLAST
GLT-1 and ATP1α1 was detected by immunofluorescence. Results After modeling
Zea Longa score and MAS score were increased(P
<

the level of Glu in the ischemic area of cerebral hippocampus was increased(P

while the expression levels of GLAST

ATP1α1 protein and mRNA were all decreased(P

all the increased and decreased levels of the indexes mentioned above were reversed in the two acupuncture groups relevant to the model group(P
