AM alleviated the apoptosis of neural cells after SCI. Spinal cord tissues were prepared and assessed by TUNEL at 7 and 14 days after SCI. The brown positive cells were apoptotic cells and pointed by red arrows. Ratio of apoptotic cells to total cells was counted. Data are expressed as the mean ± SD (n = 4). * Compared to that from SCI 7d group, P < 0.05; # Compared to that from SCI 7d group, P < 0.05. SCI: spinal cord injury; AP: acupuncture; MX: moxibustion; AM: acupuncture combined with moxibustion
