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-${\alpha}$(TNF-${\alpha}$) following sciatic crushed nerve injury in rats were investigated. For this study, walking tract analysis, plantar test, western blot for COX-2 and TNF-${\alpha}$, 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-${\alpha}$ 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-${\alpha}$ 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.

Purpose: The purpose of this study was to develop a 12-week structured exercise program (12-week-SEP) and evaluate its effects on pain, physical function and quality of life in patients with total hip arthroplasty (THA). Methods: A nonequivalent control group non-synchronized design was utilized to examine the effects of the 12-week-SEP on patients' outcomes after THA. A total of 46 adult patients (experimental group=25, control group=21) who had THA were recruited for the study. The 12-week-SEP consisted of education, exercise (muscle strengthening and progressive walking), and feedback. Data were analyzed by SPSS/WIN 21.0 using the $x^2$ test and repeated measures ANOVA. Results: The mean age of the participants was 60.9 years and 25 men (54.5%) and 21 women (45.7%) were included in the study. There were significant intervention effects on pain reduction and increased physical function but no effects on quality of life. Conclusion: The 12-week-SEP provided pain relief and enhanced physical function in patients underwent THA. Clinical application of the 12-week-SEP can improve postoperative nursing practices for patients with THA. Future research with larger sample is of necessity to obtain greater generalizability of the empirical evidences of the 12-week-SEP.

Nitric oxide (NO), a diffusible gas, is produced in the central nervous system, including the spinal cord dorsal horn and the trigeminal nucleus, the first central areas processing nociceptive information from periphery. In the spinal cord, it has been demonstrated that NO acts as pronociceptive or antinociceptive mediators, apparently in a concentration-dependent manner. However, the central role of NO in the trigeminal nucleus remains uncertain in support of processing the orofacial nociception. Thus, we here investigated the central role of NO in formalin (3%)-induced orofacial pain in rats by administering membrane-permeable or -impermeable inhibitors, relating to the NO signaling pathways, into intracisternal space. The intracisternal pretreatments with the NO synthase inhibitor L-NAME, the NO-sensitive guanylate cyclase inhibitor ODQ, and the protein kinase C inhibitor GF109203X, all of which are permeable to the cell membrane, significantly reduced the formalin-induced pain, whereas the membrane-impermeable NO scavenger PTIO significantly enhanced it, compared to vehicle controls. These data suggest that an overall effect of NO production in the trigeminal nucleus is pronociceptive, but NO extracellularly diffused out of its producing neurons would have an antinociceptive action.

Background: Reactive oxygen species play critical roles in homeostasis and cell signaling. Dexmedetomidine, a specific agonist of the ${\alpha}2$-adrenoceptor, has been commonly used for sedation, and it has been reported to have a protective effect against oxidative stress. In this study, we investigated whether dexmedetomidine has a protective effect against $H_2O_2$-induced oxidative stress and the mechanism of $H_2O_2$-induced cell death in normal human fetal osteoblast (hFOB) cells. Methods: Cells were divided into three groups: control group-cells were incubated in normoxia without dexmedetomidine, hydrogen peroxide ($H_2O_2$) group-cells were exposed to $H_2O_2$ ($200{\mu}M$) for 2 h, and Dex/$H_2O_2$ group-cells were pretreated with dexmedetomidine ($5{\mu}M$) for 2 h then exposed to $H_2O_2$ ($200{\mu}M$) for 2 h. Cell viability and apoptosis were evaluated. Osteoblast maturation was determined by assaying bone nodular mineralization. Expression levels of bone-related proteins were determined by western blot. Results: Cell viability was significantly decreased in the $H_2O_2$ group compared with the control group, and this effect was improved by dexmedetomidine. The Hoechst 33342 and Annexin-V FITC/PI staining revealed that dexmedetomidine effectively decreased $H_2O_2$-induced hFOB cell apoptosis. Dexmedetomidine enhanced the mineralization of hFOB cells when compared to the $H_2O_2$ group. In western blot analysis, bone-related protein was increased in the Dex/$H_2O_2$ group. Conclusions: We demonstrated the potential therapeutic value of dexmedetomidine in $H_2O_2$-induced oxidative stress by inhibiting apoptosis and enhancing osteoblast activity. Additionally, the current investigation could be evidence to support the antioxidant potential of dexmedetomidine in vitro.

In the present study, the effect of intrathecal (i.t.) or intracerebroventricular (i.c.v.) administration with cholera toxin (CTX) on the blood glucose level was examined in ICR mice. The i.t. treatment with CTX alone for 24 h dose-dependently increased the blood glucose level. However, i.c.v. treatment with CTX for 24 h did not affect the blood glucose level. When mice were orally fed with D-glucose (2 g/kg), the blood glucose level reached to a maximum level at 30 min and almost returned to the control level at 120 min after D-glucose feeding. I.c.v. pretreatment with CTX increased the blood glucose level in a potentiative manner, whereas i.t. pretreatment with CTX increased the blood glucose level in an additive manner in a D-glucose fed group. In addition, the blood glucose level was increased in formalin-induced pain animal model. I.c.v. pretreatment with CTX enhanced the blood glucose level in a potentiative manner in formalin-induced pain animal model. On the other hand, i.t. pretreatment with CTX increased the blood glucose level in an additive manner in formalin-induced pain animal model. Our results suggest that CTX administered supraspinally or spinally differentially modulates the regulation of the blood glucose level in D-glucose fed model as well as in formalin-induced pain model.

마사지 치료는 1회 치료만으로 통증을 경감시키고 스트레스를 이완시킵니다. 그러나 아직까지 1회 마사지 치료의 효과에 대한 객관적인 데이터를 확인한 연구가 없었습니다. 그래서 본 연구에서는 마사지 치료와 동일한 효과가 있는 것으로 보고된 척추 마사지 기구로 1회 치료를 실시하여 통증 경감과 스트레스 이완의 효과의 증거를 확인하고자 하였습니다. 10년 전부터 시각적상사척도 4점의 요통이 있었던 45세 남자 환자 1인을 대상으로 척추 마사지 기구를 실시한 1차 실험과 침상안정을 실시한 2차 실험을 실시하였습니다. 시각적상사척도 측정과 실시간으로 심박 변이도를 측정하여 자율신경계를 확인하였고 총 5회 혈액검사를 실시하여 스트레스 관련 혈액검사(코르티솔, 에피네프린, 노르에피네프린)를 실시하였습니다. 침상안정을 취한 2차 실험에 비해 척추 마사지 기구로 1회 치료를 받은 1차 실험에서 유의미한 통증 감소효과를 보였습니다. 또한 1차 실험에서 자율신경계 활성도 및 부교감 신경계의 활성도가 증가되어 있었으며 혈중 에피네프린과 노르에피네프린이 감소되어 있었습니다. 이것은 기존의 마사지 치료 효과와 동일한 결과이며 1회 척추 마사지 기구를 통해 얻어지는 효과의 증거라 사료됩니다.

Pulmonary edema is a major cause of mortality due to acute lung injury (ALI). The involvement of protein kinase C-${\delta}$ (PKC-${\delta}$) in ALI has been a controversial topic. Here we investigated PKC-${\delta}$ function in ALI using PKC-${\delta}$ knockout (KO) mice and PKC inhibitors. Our results indicated that although the ability to produce proinflammatory mediators in response to LPS injury in PKC-${\delta}$ KO mice was similar to that of control mice, they showed enhanced recruitment of neutrophils to the lung and more severe pulmonary edema. PKC-${\delta}$ inhibition promoted barrier dysfunction in an endothelial cell layer in vitro, and administration of a PKC-${\delta}$-specific inhibitor significantly increased steady state vascular permeability. A neutrophil transmigration assay indicated that the PKC-${\delta}$ inhibition increased neutrophil transmigration through an endothelial monolayer. This suggests that PKC-${\delta}$ inhibition induces structural changes in endothelial cells, allowing extravasation of proteins and neutrophils.

A solitary fibrous tumor (SFT) is a rare neoplasm originated from the pleura, but they can occur in a variety of extrathoracic regions. Although many cases of primary SFT have been reported, there are extremely rare repots to date of a malignant SFT in the spine or skull. A 54-year-woman visited our hospital due to low back pain and both leg radiating pain. Several imaging studies including magnetic resonance imaging and computed tomography revealed expansive enhanced lesions in the occipital bone, T8, S1-2, and ilium, with neural tissue compression. We performed surgical resection of the tumor in each site, and postoperative radiosurgery and chemotherapy were performed. However, after six months, tumors were recurred and metastasized in multiple regions including whole spine and lung. The authors report here the first case of patient with malignant SFT of tandem lesions in the various bony structures, including skull, thoracic spine, and sacral spine, with a rapid recurrence and metastasis. Although malignant SFT is extremely rare, it should be considered in the differential diagnosis and carful follow-up is needed.

Peripheral nerve injuries are a commonly encountered clinical problem and often result in chronic pain and severe functional deficits. At the Dept. of Oriental Rehab. Medicine, we have used for pain control a herbal bath containing the following herbs: Harpagophytum radix, Atractylodes japonica and Corydalis tuber. In the present study, we investigated the effects of this herbal bath on the recovery rate of the locomotor function and the expression of c-Fos in the ventrolateral periaqueductal gray (vIPAG) region of the brain following sciatic crushed nerve injury in rats. In the present study, characteristic gait change with decreasing of the sciatic function index (SFI) was observed and c-Fos expression in the vIPAG was suppressed following sciatic crushed nerve injury in rats. Immersion into herbal bath enhanced SFI value and restored c-Fos expression in the vIPAG to the control value. These results suggest the herbal bath might activate neurons in the vIPAG, and could facilitate functional recovery from peripheral nerve injury.

Active and therapeutic sport recovery is becoming a popular and important component in approving performance for pro and recreational athletes alike. It is also helping in the realm of injury prevention. In the search of finding modalities that are widely effective, natural, and safe, acupuncture is a viable and cost-effective treatment for helping athletes achieve this goal. More direct related research is needed, but testimonials from pro athletes and the body of research that currently exists provides powerful evidence on acupunctures ability to help with enhancing recovery. Specializing in acupuncture and exercise science, Chris integrates acupuncture into musculoskeletal rehabilitation therapy or fitness training for pain modulation, speedy recovery, and enhanced performance. Clients can choose to focus on one-on-one corrective exercise therapy, manual and massage therapy, or acupuncture. However, for best results, Chris recommends all three. Other modalities that he uses in therapy are acu-taping, herbal therapy, nutrition supplementation, cupping, guasha, and stretching techniques. The corrective exercise component is one-on-one body balancing management, focusing on strength and conditioning, post physical rehab - exercise therapy, integrative sport specific exercise, weight loss, core strengthening, dynamic lumbar stabilization, active recovery techniques, and myo-fascial release techniques. The acupuncture component focuses on sport injuries, myofascial pain, peripheral neuropathy, arthritis, facial rejuvenation, stress, smoking cessation, addiction detoxification program, weight management, sport recovery and performance.
