Low Frequency Electroacupuncture Alleviated Spinal Nerve Ligation Induced Mechanical Allodynia by Inhibiting TRPV1 Upregulation in Ipsilateral Undamaged Dorsal Root Ganglia in Rats

Figure 4

Western blotting analysis of CGRP levels in ipsilateral L5, L4, and L6 DRGs in normal, SNL, and SNL + EA groups. Results were expressed as relative fold changes as compared to normal group after normalization to β-actin. Data are presented as mean ± SEM of three independent experiments. ^∗𝑃<0.05, ^∗∗𝑃<0.01, SNL group or SNL + EA group versus normal group; ^##𝑃<0.01, ^###𝑃<0.001, SNL + EA group versus SNL group.
