Effect of EA on ultrastructure of hippocampal neurons in diabetic rats. A Electron microscopic pictures of hippocampal neurons in diabetic rats. Scale bar = 1 μm, magnification ×6000. The protective effects of EA on ultrastructural damage in the hippocampus CA1 area of diabetic rats were identified by electron microscopy. B Comparison of the number of autophagic vacuoles in diabetic rats. Data are expressed as mean ± standard error of the mean (n = 8 in each group). *p < 0.05 versus control group; ^#p < 0.05 versus model group; ^△p < 0.05 versus EA group
