Scalp acupuncture reduced MCAO-induced neuronal apoptosis. (A) H&E staining and (B) Nissl staining results obtained for brain tissue sections based on photographs of specimens as viewed using an optical microscope. (C) Apoptotic cells in brains as detected using TUNEL staining. (D) Numbers of apoptotic cells, as calculated using ImageJ. Results represent triplicate independent experiments and are expressed as the mean ± standard deviation (n = 4). ##p < 0.01 (MCAO vs CON); **p < 0.01 (ACU vs MCAO).
