The Effect of Repeated Electroacupuncture Analgesia on Neurotrophic and Cytokine Factors in Neuropathic Pain Rats

Figure 1

Effect of EA treatment on spinal IL-1β expression on astrocytes in different groups. The expression of IL-1β is shown in red and GFAP in green; the coexpression of IL-1β and GFAP is yellow. GFAP is the marker for the astrocytes, suggesting the expression of astrocytes (green). The histogram shows the count of the coexpression of IL-1β and GFAP (yellow). The yellow area represents the expression of IL-1β on the astrocytes. The coexpression level of IL-1β and GFAP (yellow) was increased after CCI and decreased after repeated EA treatment. Scale bar: 200 μm. EA2D: after 2 days’ EA treatment; EA1W: after 1 week’s EA treatment; EA2W: after 2 weeks’ EA treatment; compared with the normal group; compared with the CCI group; compared with the CCI+EA2D group.
