Objectives : The purpose of this study was to evaluate whether acupuncture at $SP_6$ attenuates esophageal inflammation on refluxed-induced esophagitis. Methods : Acupuncture at $SP_6$ was stimulated by acupuncture torsion technique for 30 seconds four times every hour after an operation induced reflux esophagitis(RE), and its effects were assessed in comparison with RE rats without acupuncture, and normal rats. Results : $SP_6$ acupuncture stimulation markedly ameliorated mucosal damage in the histological evaluation. Reflux-induced esophagitis rats exhibited the down-regulation of antioxidant-related protein expression levels such as heme oxygenase-1(HO-1) in the esophagitis; however, the associated levels with $SP_6$ acupuncture stimulation were significantly higher than those in RE rats without acupuncture stimulation. Moreover, $SP_6$ acupuncture stimulation significantly reduced the expression of inflammatory proteins through mitogen-activated protein kinase(MAPK)-related signaling pathways. The increased protein expressions of inflammatory mediators, cyclooxygenase-2(COX-2) and inducible nitric oxide synthase(iNOS), by nuclear factor-kappa B(NF-kB) activation were significantly suppressed through $SP_6$ acupuncture stimulation. Conclusions : Our findings support the therapeutic evidence for $SP_6$ acupuncture stimulation alleviating the development of esophagitis via regulating inflammation through the activation of the antioxidant pathway.

Background: Spasmodic torticollis is a disorder that is described by sustained muscle contractions causing repetitive and twisting movements, and abnormal postures in a single body region. The purpose of this case is to describe the manual therapy for a patient with spasmodic torticollis. Methods: The patient was a 64 years old man with an 3 month history of left side laterocollis spasmodic torticollis. No known genetic history or trauma. Prior to intervention, his score on the Western Spasmodic Torticollis Rating Scale (TWSTRS) severity score was 24, disability score was 20, pain score was 11. There is a noticeable distinction between left and right side cervical range of motion. The intervention consisted of manual therapy (MET, PNF) 3 times per week for the treatment during 4 weeks. Results: After intervention for 4weeks, his TWSTRS score and range of motion was improved quite a bit before therapeutic exercise. But symptoms are not improving sufficiently fast. Conclusions: Manual therapy is that MET and PNF is effective in improving for patient had spasmodic torticollis with laterocollis of neck.

Background: Lumbar epidural steroid injection for relief of low back pain and sciatica has become a popular procedure. further, cervical epidural steroid injection with nerve block (CESNB) is known to be effective for the management of acute and chronic pain of neck, shoulder and arm. However, many anesthesiologists are not familiar with CESNB. Methods: Charts of 34 patients who had undergone 60 cervical epidural steroid injections over a three year period, 1993 to 1995, were reviewed. We studied the followings: initial visit and department, injected interspaces, personal characteristics, indications for injection and complications. Results: Patients' first visits were mainly to orthopaedics (11 patients) and neurosurgery (10 patients). Epidural injection sites were: C7-T1 interspace (29 patients) and C6-C7 interspace (6 patients). Mean age of patients were 50.1 years. range 21~73 years. There were twenty male and fourteen female patients. Complications varied from dizziness after CESNB (1 patient). loss of consciousness with transient apnea (2 patients), and local infection with suspicious meningitis (1 patient). Conclusion: We conclude from the above data that CESNB is a good, safe and conservative form of therapeutic procedure in the management of patients suffering from cervical radiculopathy, and neck and shoulder pain.

CT는 단층촬영을 이용한 의학적인 영상 진단 기법이다. CT는 3차원적인 방사선학적 영상 기법으로 염증의 평가에는 적합하지 않으나, 석회화된 조직을 직접적인 3차원 영상으로 보여주므로 뼈 손상의 평가에는 유용하다. 본 연구는 실험적으로 유도된 랫드의 보조관절염에서 관절의 병리학적 변화와 뼈 파괴의 정량적 분석을 3차원 CT 영상을 통하여 평가하고자 실시되었다. 그 결과 랫드의 보조관절염에서 병변의 파괴성 진행이 3차원 CT 영상을 통해 정량화될 수 있었고, 따라서 관절염 질환의 상태 및 실험적인 치료 약제의 효능 평가에 3차원 CT 영상 기법이 효과적일 것으로 생각된다.

MiRNAs are non-coding RNAs that play a role in the regulation of major processes. The inhibition of miRNAs using antisense oligonucleotides (ASOs) is a unique and effective technique for the characterization and subsequent therapeutic targeting of miRNA function. Recent advances in ASO chemistry have been used to increase both the resistance to nucleases and the target affinity and specificity of these ASOs. Peptide nucleic acids (PNAs) are artificial oligonucleotides constructed on a peptide-like backbone. PNAs have a stronger affinity and greater specificity to DNA or RNA than natural nucleic acids and are resistant to nucleases, which is an essential characteristic for a miRNA inhibitor that will be exposed to serum and cellular nucleases. For increasing cell penetration, PNAs were conjugated with cell penetrating peptides (CPPs) at N-terminal. Among the tested CPPs, Tat-modified peptide-conjugated PNAs have most effective function for miRNA inhibition. PNA-based ASO was more effective miRNA inhibitor than other DNA-based ASOs and did not show cytotoxicity at concentration up to 1,000 nM. The effects of PNA-based ASOs were shown to persist for 9 days. Also, PNA-based ASOs showed considerable stability at storage temperature. These results suggest that PNA-based ASOs are more effective ASOs of miRNA than DNA-based ASOs and PNA-based ASO technology, compared with other technologies used to inhibit miRNA activity can be an effective tool for investigating miRNA functions.

In the 40 years since the first benzodiazepine was brought into clinical use there has been a substantial growth in understanding the molecular basis of action of these drugs and the role of their receptors in anxiety disorders. Benzodiazepine receptors are present throughout the brain with the highest concentration in cortex, and it potentiate and prolong the synaptic action of the inhibitory neurotransmitter GABA. Central benzodiazepine receptors and $GABA_A$ receptors are part of the same macromolecular complex. Abnormalities of these $GABA_A$-benzodiazepine receptors as a result of drug challenge tests and neuroimaging studies may underlie some anxiety disorders. The role of $GABA_A$-benzodiazepine receptors in the action of benzodiazepine and as a factor in anxiety disorder, in both animal and humans including knock-out and knock in technique, may lead to new anxiolytics that have potentially significant therapeutic gains without unwanted side effects.

Discriminating between two herbal medicines (Panax ginseng and Panax quinquefolius), with similar chemical and physical properties but different therapeutic effects, is a very serious and difficult problem. Differentiation between two processed ginseng genera is even more difficult because the characteristics of their appearance are very similar. An ultraperformance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF MS)-based metabolomic technique was applied for the metabolite profiling of 40 processed P. ginseng and processed P. quinquefolius. Currently known biomarkers such as ginsenoside Rf and F11 have been used for the analysis using the UPLC-photodiode array detector. However, this method was not able to fully discriminate between the two processed ginseng genera. Thus, an optimized UPLC-QTOF-based metabolic profiling method was adapted for the analysis and evaluation of two processed ginseng genera. As a result, all known biomarkers were identified by the proposed metabolomics, and additional potential biomarkers were extracted from the huge amounts of global analysis data. Therefore, it is expected that such metabolomics techniques would be widely applied to the ginseng research field.

The nitrone-based free radical trapping reagent, $\alpha$-phenyl-n-tert-butyl nitrone (PBN) has been proposed as therapeutic agent for stroke. We used this for model drug of development of new drug for neuroprotection. The purpose of this study was to evaluate the blood-brain barrier (BBB) permeability of PBN in Sprague-Dawly (SD) rats. The BBB transport of PBN was investigated in SD rats using internal carotid artery perfusion (ICAP) method at a rate of 4 mι/min for 15 second. We also obtained pharmacokinetic parameters of PBN using single intravenous injection technique. When we estimated BBB permeability of PBN with ICAP method, the brain volume of distribution of PBN was 60.0 $\pm$ 12.0 $\mu\textrm{g}$/ι. The brain uptake of PBN after IV injection at 120 min was 0.15 $\pm$ 0.01%ID/g. The PBN was transported to the brain through the BBB well in rats, because PBN is small molecule (MW 177) and lipid-soluble (log P 1.23) compound.

Arteriovenous malformations (AVMs) are characterized by the presence of abnormal connections between feeding arteries and draining veins. It is generally assumed that symptomatic lesions can preferably be treated. Due to high arterial blood flow, there is a risk of bleeding with surgical excision alone, which can be massive and life threatening during the operation. According to recent advances in interventional technique, a hybrid approach using embolization of the feeding artery with subsequent immediate excision of the AVM for successful management of vascular lesions could be applied to AVMs. Herein, we describe a case of successful excision of AVM in the left soleus muscle using a hybrid approach.

Refractory angina pectoris is defined as angina refractory to optimal medical treatment and standard coronary revascularization procedures. Despite recent therapeutic advances, patients with refractory angina pectoris are not adequately treated. Spinal cord stimulation is a minimally invasive and reversible technique which utilizes electrical neuromodulation by means of an electrode implanted in the epidural space. It has been reported to be an effective and safe treatment for refractory angina pectoris. We report a case of spinal cord stimulation which has effectively relieved chest pain due to coronary artery disease in a 40-year-old man. This is the first report of spinal cord stimulation for treatment of refractory angina pectoris in South Korea.
