Effect of Electroacupuncture on Rats with Chronic Constriction Injury-Induced Neuropathic Pain

Figure 2

Effect of EA on cortical TRPV4 immunostaining positive cells in SD rats with CCI-induced neuropathic pain. TRPV4 immunostaining positive cells (arrow) of the cerebral cortex (cortex) increased in the control group without treatment (control) than those in the normal group (normal). These increases were reduced for the 2EA (2EA) and 15EA (15EA) treatment, but not for the Sham EA treatment (sham). normal = normal group; control = control group; sham = sham group; 2EA = 2EA group; 15EA = 15 EA group.
