Abstract

Objective : Neuropathic pain can be caused by a partial peripheral nerve injury. This kind of pain is usually accompanied by spontaneous burning pain, allodynia and hyperalgesia. It is not clear that scolopendrid aqua-acupuncture can control neuropathic pain effectively. The purpose of this study is to examine if scolopendrid aqua-acupuncture may be effective to the neuropathic pain (mechanical allodynia, cold allodynia) in a rat model of neuropathic pain. Methods : To produce the model of neuropathic pain, under isoflurane 2.5% anesthesia, tibial nerve and sural nerve was resected. After the neuropathic surgery, the author examined if the animals exhibited the behavioral signs of allodynia. The allodynia was assessed by stimulating the medial malleolus with von Frey filament and acetone. Three weeks after the neuropathic surgery, scolopendrid aqua-acupuncture was injected at Hwando(GB30) one time a day for one week. After that the author examined the withdrawl response of neuropathic rats' legs by von Frey filament and acetone stimulation. And also the author examined c-fos in the midbrain central gray of neuropathic rats and the change of WBC count in the blood of neuropathic rats. Results & Conclusion : 1. The scolopendrid aqua-acupuncture injected at Hwando(GB30) decreased the withdrawl response of mechanical allodynia in SHA-1, SHA-2 and SAH-3 group as compared with control group. 2. The scolopendrid aqua-acupuncture injected at Hwando(GB30) decreased the withdrawl response of chemical allodynia(cold allodynia) in SHA-1, SHA-2 and SAH-3 group as compared with control group. 3. The scolopendrid aqua-acupuncture injected at Hwando(GB30) showed the significant difference between sham group and control group(p=0.01), sham and SHA-3 group(p=0.026), control group and SHA-1 group(p=0.01), control group and SHA-2 group(p=0.024) in the c-fos expression. 4. The scolopendrid aqua-acupuncture injected at Hwando(GB30) showed the significant difference between sham group and SHA-3 group(p=0.010), control group and SHA-3 group(p=0.006) in the WBC count.
