Figure 2. Electro-acupuncture inhibited cell apoptosis and inflammation in ventral horn of injured spinal cord. A. Protein level of cleaved caspase 3, Bax and Bcl2 measured with Western blotting; B, C. Relative level of cleaved caspase 3 and ratio of Bax to Bcl2 quantified by densitometric analysis; D. Relative level of inflammatory factors TNF-α and IL-1β measured with Western blotting; E. Densitometric analysis results of the protein levels of TNF-α and IL-1β. *P < 0.05, **P < 0.01, compared with Sham group; ^#P < 0.05, ^##P < 0.01, compared with SCI group.
