The effect of electroacupuncture on Nissl staining-positive neurons in rat hippocampal CA1 region. (a) Representative Nissl staining images at the end of observation in rat hippocampal CA1 region (arrow) of Wistar (a1), Wistar + Sham (a2), Wistar + EA (a3), SHR (a4), SHR + Sham (a5), and SHR + EA (a6) group, respectively. Bar = 50 μm. b1–b6, high magnification of a1–a6, respectively. Bar = 200 μm. (b) Quantitative evaluation of Nissl staining-positive neurons. Wistar: Wistar rats without any treatment. Wistar + Sham: Wistar rats with stimulation at nonacupoints. Wistar + EA: Wistar rats with stimulation at acupoints. SHR: SHR without any treatment. SHR + Sham: SHR with stimulation at nonacupoints. SHR + EA: SHR with stimulation at acupoint. Data were expressed as mean ± SD from six animals. *P < 0.05 versus Wistar group; ^# P < 0.05 versus SHR group; ^§ P < 0.05 versus SHR + Sham group.
