Electroacupuncture Ameliorates Tibial Fracture-Induced Cognitive Dysfunction by Elevating α7nAChR Expression and Suppressing Mast Cell Degranulation in the Hippocampus of Rats

Figure 5

EA inhibited tibial fracture-induced apoptosis in the hippocampus. Hippocampal sections (10 µm) were prepared 1 and 3 days after surgery. (a) The apoptosis of neuronal cells was detected using TUNEL. (b) Quantification of apoptotic cells in the hippocampal CA1 region on day 1 and 3 postoperatively. Graphs show the mean ± S.E.M (n = 4). ∗∗ versus the control group; versus the Op group; versus the EA group; scale bar = 25 µm.
