A 19-year-old male patient presented with facial hemi-atrophy with unilateral spasms of the masseter and temporalis muscles. Ultrasound therapy and Transcutaneous Electric Nerve Stimulation therapy, known as combination therapy, were given on alternate days for 2 weeks. At the end of 2 weeks of combination therapy the patient reported a drastic reduction in the number of episodes of muscle spasm. The visual analog scale score for tenderness of the masseter and temporalis was also markedly reduced. No one has previously used combination therapy for the treatment of facial hemi-atrophy with hemi-facial spasms. The encouraging results of the combination therapy has prompted us to document this study.

To elucidate the action of $P_2$-purinoceptor, effects of adenosine triphosphate(ATP) and perivascular nerve stimulation were investigated from polygraph in the isolated renal artery of rabbit 1. ATP caused the relaxation on the precontraction with noradrenaline$(10{\mu}M)$ on the presene and absence of endothelium in the isolated renal artery of rabbit, the relaxative response was increased between 0.1 and $30{\mu}M$ on dose-dependent manner. 2. The relaxative response induced by ATP$(10{\mu}M)$ on precontraction with noradrenaline$(10{\mu}M)$ was blocked by the pretreatment with reactive blue 2$(10{\mu}M)$. 3. ATP inhibited the contractile response by perivascular nerve stimulation(0.3ms, 80V, 50Hz, 1 sec), the inhibitory action was blocked by the pretreatment with 8-phenyltheophylline$(10{\mu}M)$.

Magnetic nerve stimulation treatment is much backward real condition than other field. Specially, successful medical treatment introduction of magnetic field (MF) can was refered long ago in Avicenna's work, and is thought as age of medicine magnetology development recently. These development is achieved through biologist and biophysicist and clinician's joint effort, but, new mountings and relationship air tassel are developed steadily. Magnetic nerve stimulation treatment field designs treatment system by each function during long wave high-amplitude (traditional magneto therapy of greatly great that strong that) short time that CMF, VMF, PMF field etc. are representative but are HPMT technology in this research and manufacture and special quality did comparative analysis.

Facial nerve paralysis(or Bell's palsy) which commonly occurs unilaterally, gives rise to paralysis of facial expression muscle. This condition is classified into symptomatic facial nerve paralysis due to intracranial tumor, post operative trauma, etc. and idiopathic facial nerve paralysis. To explain the etiology of idiopathic facial nerve paralysis, many hypothesis including ischemic theory, viral infection, exposure to cold, immune theory etc. were suggested, but there is no agreement at this point. The method to evaluate the facial nerve paralysis, when it occurs, consists of three stage scale method, image thechnics like CT and MRI, laboratory test to examine the antibody titers of viral infection, neurophysiologic test to evaluate the degree and prognosis of paralysis. Treatment includes medication, stellate ganglion block(SGB), surgery, physical therapy and other home care therapy. In medication, systemic steroids, vitamins, vasodilating-drug and ATP drugs were used. SGB was also used repeatedly to attempt the improvement of circulation and to stimulate the recovery of nerve function. Physical therapy including electric acupuncture stimulation therapy(EAST) and hot pack was used to prevent the muscle atrophy. When No response was showed to this conservative therapies, surgery was considered. After treating two patients complaining of Bell's palsy with medication(systemic steroids) and EAST, favorable result was obtained. so author report the case of facial nerve paralysis.

Background: Transcutaneous Electrical Nerve Stimulation (TENS) has been widely used for pain relief after surgery instead of opioid analgesics therapy. This study was designed to study the effectiveness of TENS on perianal pain after anal surgery. Methods: Forty-eight patients who underwent anal surgery were evaluated in this suudy. Caudal anesthesia with 1.5% lidocaine 30 ml mixture 1：200,000 epinephrine was performed. TENS was done at 100 Hz for 25 min. duration, postoperatively at 4 hrs and 24 hrs. Pain was also measured at the 4 hrs and 24 hrs postoperatively by visual analogue scale (VAS). VAS value were compared before and after TENS application. Results: Values of VAS after TENS were significantly lower compared to those before TENS. Conclusions: From these results, we concluded, TENS may be effective for postoperative perianal pain relief after anal surgery.

The rostral ventrolateral medulla (RVLM) has been established recently as a sympathoexcitatory area. The present study was conducted to investigate whether the somatosympathetic pressor and/or depressor responses are mediated through RVLM in cats anesthetized with ${\alpha}-chloralose$. An occipital craniectomy was performed and ventrolateral medulla were stimulated either electrically or chemically to evoke changes in arterial blood pressure. And then the effect of lesions in the ventrolateral medulla on the changes in blood pressure elicited by the peripheral nerve stimulation was observed. Followings are the results obtained: 1) Pressor areas were found in the ventrolateral medulla, lateral reticular nucleus and rostral dorsal area. 2) Depressor areas were found mainly in the ventrolateral medulla rostral to the pressor areas. 3) Some areas showed biphasic responses: a depressor response to lower frequency and a pressor response to higher frequency stimulation. 4) After electrical lesion in pressor area in RVLM, the somatosympathetic pressor response was abolished or depressed markedly. The somatosympathetic depressor response, however, remained after the lesion. 5) Electrical lesion in the depressor area abolished somatosympathetic depressor response. From the above results it is concluded that somatosympathetic pressor response is mediated through RVLM, while somatosympathetic depressor response is not mediated through RVLM.

Sphincter of Oddi dysfunction (SOD) is a syndrome of chronic biliary pain or recurrent pancreatitis due to the functional obstruction of the pancreaticobiliary flow. We report a case of spinal cord stimulation (SCS) for chronic abdominal pain due to SOD. The patient had a history of cholecystectomy and had suffered from chronic right upper quadrant abdominal pain. The patient had been diagnosed as having SOD. The patient was treated with opioid analgesics and nerve blocks, including a splanchnic nerve block. However, two years later, the pain became intractable. We implanted percutaneous SCS at the T5-7 level for this patient. Visual analog scale (VAS) scores for pain and the amount of opioid intake decreased. The patient was tracked for more than six months without significant complications. From our clinical case, SCS is an effective and alternative treatment option for SOD. Further studies and long-term follow-up are necessary to understand the effectiveness and the limitations of SCS on SOD.

Schwann cells play an important role in peripheral nerve regeneration. Upon neuronal injury, activated Schwann cells clean up the myelin debris by phagocytosis, and promote neuronal survival and axon outgrowth by secreting various neurotrophic factors. However, it is unclear how the nerve injury induces Schwann cell activation. Recently, it was reported that certain cytoplasmic molecules, which are secreted by cells undergoing necrotic cell death, induce immune cell activation via the toll-like receptors (TLRs). This suggests that the TLRs expressed on Schwann cells may recognize nerve damage by binding to the endogenous ligands secreted by the damaged nerve, thereby inducing Schwann cell activation. Accordingly, this study was undertaken to examine the expression and the function of the TLRs on primary Schwann cells and iSC, a rat Schwann cell line. The transcripts of TLR2, 3, 4, and 9 were detected on the primary Schwann cells as well as on iSC. The stimulation of iSC with poly (I : C), a synthetic ligand for the TLR3, induced the expression of $TNF-{\alpha}$ and RANTES. In addition, poly (I : C) stimulation induced the iNOS expression and nitric oxide secretion in iSC. These results suggest that the TLRs may be involved in the inflammatory activation of Schwann cells, which is observed during Wallerian degeneration after a peripheral nerve injury.
