Figure 1

Pathological changes of spinal cord tissues in the spinal cord injury (SCI) rat model after electroacupuncture (EA) treatment for 14 days. Sham: sham operation, postoperative anti-infection agents, fixed in the prone position for 30 min starting at 11:00 daily 24 h after sham operation for 14 days; SCI: modeling, postoperative anti-infection agents and nursing, fixed in the prone position for 30 min starting at 11:00 daily 24 h after modeling for 14 days; SCI+EA: modeling, postoperative anti-infection agents and nursing, EA treatment at bilateral Zusanli points for 30 min starting at 11:00 daily 24 h after modeling for 14 days. Spinal cord tissues were stained by hematoxylin and eosin and observed under light microscopy (×40).
