Downregulation of Spinal G Protein-Coupled Kinase 2 Abolished the Antiallodynic Effect of Electroacupuncture
EA treatment attenuated the severity of mechanical allodynia inflammatory hypernociception induced by complete Freund’s adjuvant (CFA). Single (a) and repeated (b) EA treatment statistically raised the decreased mechanical threshold. However, sham EA treatment did not exhibit any effect on paw withdrawal threshold (PWT). The data are expressed as the mean ± SEM (, versus saline group; #, ### versus sham EA group).
