Electroacupuncture (EA) treatment limits neuronal cell death in the hippocampal CA1 and CA3 regions in SAMP8 mice. (a) Representative images of TUNEL staining in the hippocampal CA1 and CA3 regions from SAMR1 or SAMP8 mice. Magnification, ×400, ×800, and ×1600. Scale bars, 50 μm, 25 μm, and 12.5 μm. (b) The number and ratio of TUNEL-positive cells in the CA1 region. (c) The number and ratio of TUNEL-positive cells in the CA3 region. Data are the mean ± SD (n = 10 per group). ^∗∗∗P < 0.001 and ^∗∗P < 0.01 vs. the model group; #P < 0.05 vs. the 2 Hz EA group. ns: not significant.
