Effects of Zusanli and Ashi Acupoint Electroacupuncture on Repair of Skeletal Muscle and Neuromuscular Junction in a Rabbit Gastrocnemius Contusion Model

Figure 6

Content of acetylcholinesterase (AChE) in the recruited muscles. The optical density (OD) value at 492 nm obtained by ELISA was provided for skeletal muscle samples for the AChE protein. Increases in AChE content were observed in the treatment groups compared to that of contusion group at different time points during repair (P < 0.05). Compared with that of the EA-ST36 group, AChE content in the EA-Ashi group was higher on day 7 but became lower on the 28th day (P < 0.05) (EA-Ashi versus EA-ST36, ^▲P < 0.05; EA-AS versus EA-Ashi and EA-ST36), ^#P < 0.05; contusion group versus treatment groups, ^★P < 0.05; EA-Ashi, electroacupuncture at Ashi acupoints; EA-ST36, electroacupuncture at ST36; EA-AS, electroacupuncture at Ashi acupoints and ST36; treatment groups (EA-Ashi, EA-ST36, and EA-AS)).
