Objectives :In present study, we investigated the effects of ginsenoside Rg3 on early-stage inflammatory response in spinal cord compression of rodents. Methods :Spinal cord injury(SCI) was induced by a vascular clip method(30 g, 5 min) on the spinal cord of mice. Rg3 was treated orally at 1 hour prior to the SCI induction. Messenger ribonucleic acid(mRNA) expression of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6(IL-6) and cyclooxygenase-2(COX-2) was measured by the real-time polymerase chain reaction(RT-PCR). Microglia in the spinal cord tissue, neurophils and COX-2 in the peri-lesion and inducible nitric oxide synthase(iNOS) expression in the ventral horn of SCI induced rats were measured by immunohistochemical stain. Results :1. Rg3 significantly reduced the mRNA expression of TNF-α, IL-1β, and COX-2 in the spinal cord tissue compared with SCI group(p<0.05, p<0.01). 2. Rg3 significantly reduced the total number of activated microglia and proportion of phagocytic form in the total activated microglia compared with SCI group(p<0.05, p<0.01). 3. Rg3 significantly reduced myeloperoxidase(MPO) positive neurophil in the peri-lesion compared with SCI group(p<0.05). 4. Rg3 reduced the COX-2 expression in the tissue and motor neurons compared with SCI group. 5. Rg3 significantly reduced iNOS positive motor neurons in the ventral horn compared with SCI group(p<0.01). Conclusions :In conclusion, we demonstrated at first that treatment of ginsenoside Rg3 could reduce significantly the levels of inflammatory mediators in a spinal cord compression model of rodents. Therefore, these results suggested that ginsenoside Rg3 may be a useful antimiflamatory therapeutic candidate for SCI.

Objectives :Peripheral nerve injuries are commonly encountered clinical problems and often result in serve functional deficit. Bee venom and scolopendra subspinipes have been traditionally used in oriental medicine to treat several inflammatory diseases and chronic pain conditions. Methods :In the present study, the effects of bee venom pharmacopuncture and scolopendra subspinipes pharmacopuncture on functional recovery, severity of pain, and expressions of neurofilament, cycloxygenease-2(COX-2), and tumor necrosis factor-α(TNF-α) following sciatic crushed nerve injury in rats were investigated. For this study, walking tract analysis, plantar test, western blot for COX-2 and TNF-α, and immunohistochemistry for neurofilament were performed. Results :In the present results, sciatic functional index(SFI) in walking tract analysis was significantly decreased following sciatic crushed nerve injury, and pain severity in plantar test was significantly increased. COX-2 and TNF-α expressions were increased whereas neurofilament expression was decreased by sciatic crushed nerve injury. On the other hand, bee venom pharmacopuncture and scolopendra subspinipes pharmacopuncture improved SFI in walking tract analysis and suppressed the pain severity in sciatic crushed nerve injury. Bee venom pharmacopuncture and scolopendra subspinipes pharmacopuncture suppressed COX-2 and TNF-α expression and enhanced the neurofilament expression in sciatic crushed nerve injury. Conclusions :In the present study, we have shown that treatment with bee venom or scolopendra subspinipes is the effective therapeutic modality to ameliorate the symptoms of sciatic crushed nerve injury. The efficacies of bee venom and scolopendra subspinipes were similar.

Objectives :Peripheral nerve injuries are commonly encountered clinical problems and often result in severe functional deficits. Sukjiyanggeun-Tang(shúdˋlyǎngj l̄n-tāng ), in oriental medicine, has been used to treat various musculoskeletal disorders. Methods :In the present study, the effects of aqueous extract of Sukjiyanggeun-Tang(shúdˋlyǎngj l̄n-tāng ) on functional recovery, severity of pain, and expressions of neurofilament, cycloxygenease-2(COX-2), inducible nitric oxide synthase(iNOS), and tumor necrosis factor-α(TNF-α) following sciatic crushed nerve injury in rats were investigated. For this study, walking tract analysis, plantar test, western blot analysis for COX-2 iNOS, and TNF-α, and Immunofluorescence test for neurofilament were performed. Results :In the present results, sciatic functional index(SFI) in walking tract analysis was significantly decreased following sciatic crushed nerve injury, and pain severity in plantar test was significantly increased. COX-2, iNOS and TNF-α expressions were increased whereas neurofilament expression was decreased by sciatic crushed nerve injury, In contrast, treatment with Sukjiyanggeun-Tang(shúdˋlyǎngj l̄n-tāng ) improved SFI in walking tract analysis and suppressed the pain severity in sciatic crushed nerve injury. Sukjiyanggeun-Tang(shúdˋlyǎngj l̄n-tāng ) treatment also suppressed COX-2, iNOS, and TNF-α expressions and enhanced the neurofilament expression in sciatic crushed nerve injury. Conclusions :In the present study, we have shown that Sukjiyanggeun-Tang(shúdˋlyǎngj l̄n-tāng ) is the effective therapeutic modality to ameliorate the symptoms of sciatic crushed nerve injury.
