Metabolite ratios in the right and left HPC regions of the sham, MCAO and MCAO + EA groups, and left/right ratios in each group. Data are presented as mean ± standard deviation (n=12 per group).
a
P<0.05, MCAO vs. sham;
b
P<0.05, MCAO vs. MCAO + EA. HPC, hippocampus; NAA, N-acetylaspartate; Cr, creatine; Glu, glutamate; Cho, choline-containing compounds; MCAO, middle cerebral artery occlusion; EA, electroacupuncture.
