Objectives: Electroacupuncture (EA) has been demonstrated to aid stroke recovery. However, few investigations have focused on identifying the potent molecular targets of EA by comparing EA stimulation between naïve and disease models. Therefore, this study was undertaken to identify the potent molecular therapeutic mechanisms underlying EA stimulation in ischemic stroke through a comparison of mRNA sequencing data obtained from EA-treated naïve control and ischemic stroke mouse models. Methods: Using both naïve control and middle cerebral artery occlusion (MCAO) mouse models, EA stimulation was administered at two acupoints, Baihui (GV20) and Dazhui (GV14), at a frequency of 2 Hz. Comprehensive assessments were conducted, including behavioral evaluations, RNA sequencing to identify differentially expressed genes (DEGs), functional enrichment analysis, protein-protein interaction (PPI) network analysis, and quantitative real-time PCR. Results: EA stimulation ameliorated the ischemic insult-induced motor dysfunction in mice with ischemic stroke. Comparative analysis between control vs. MCAO, control vs. control + EA, and MCAO vs. MCAO + EA revealed 4,407, 101, and 82 DEGs, respectively. Of these, 30, 7, and 1 were common across the respective groups. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses revealed upregulated DEGs associated with the regulation of inflammatory immune response in the MCAO vs. MCAO + EA comparison. Conversely, downregulated DEGs in the control vs. control + EA comparison were linked to neuronal development. PPI analysis revealed major clustering related to the regulation of cytokines, such as Cxcl9, Pcp2, Ccl11, and Cxcl13, in the common DEGs of MCAO vs. MCAO + EA, with Esp8l1 identified as the only common downregulated DEG in both EA-treated naïve and ischemic models. Conclusion: These findings underscore the diverse potent mechanisms of EA stimulation between naïve and ischemic stroke mice, albeit with few overlaps. However, the potent mechanisms underlying EA treatment in ischemic stroke models were associated with the regulation of inflammatory processes involving cytokines.
Background: Bupivacaine with fentanyl might be suitable as the spinal anesthesia for performing ambulatory surgery to treat varicose vein. Material and Method: Thirty patients who underwent spinal anesthesia for a varicose vein operation were enrolled in this study. They were classified into 2 groups of either fentanyl 25ug mixed with bupivacaine 4mg (group FB4) or bupivacaine 8mg (group B8). We compared the groups for the success of the analgesia, the recovery time from sensory and motor block, the side effects and the postoperative complications. Result: The groups did not differ significantly regarding the success of analgesia (13 of 15 [group FB4], 15 of 15 [group B8]). None of the patients were converted to general anesthesia due to surgical pain. None of the patients required medication for hypotension and/or bradycardia. The operative and nonoperative side effects of motor block (tested for by using a modified Bromage scale) was significantly lower in group FB4 than that in group B8, as checked at 2 hours after spinal anesthesia (p<0.05). Recovery from spinal block was significantly quicker in group FB4 than that in group B8 (p<0.05). The first voluntary micturition time did not differ significantly (6.5 hours v 4.5 hours [p=0.143]) between the groups, but a nelatone catheter was inserted into 2 of the group B8 patients due to dysuria. Conclusion: Adequate intraoperative analgesia and hemodynamic stability and faster mobilization were achieved using bupivacaine 4mg with fentanyl 25ug. Low dose spinal anesthesia with fentanyl is suitable for performing ambulatory surgery to treat varicose vein.

Objective : This research investigated the intervention effects, protocol of modified constraint-induced movement therapy in children with hemiplegic cerebral palsy. Methods : For the key words of a database search, "Cerebral Palsy", "Hemiplegia", "Constraint Induced Movement Therapy", "modified Constraint Induced Movement Therapy" were used. We examined papers published in journals from January 2001, when the modified Constraint Induced Movement Therapy was first suggested, to May 2011, using PubMed, Medline. Ovid. Results : A total of 10 papers were analyzed and results of modified Constraint Induced Movement Therapy were an effective therapeutic method to improve motor function, quality of movement and that they also increased the frequency of functional use of the affected hands of hemiplegic cerebral palsy. Conclusion : This paper conducted a systematic review of the research literature reporting on the effects of modified constraint-induced movement therapy in children with hemiplegic cerebral palsy. Analysis of the fewer number of papers, there was limitation that we consider studies at all levels of evidence. However the restraint methods should be decided according to the characteristics of the individually and apply a variety of therapeutic activities, there is positive support for the use of modified constraint-induced movement therapy to improve the recovery of the paretic upper extremity with cerebral palsy.
Skeletal muscle fatigue is often associated with diminished athletic performance and inability to maintain an expected force output as a function of time. The purpose of this study was to compare the effect of duration of exercise on skeletal muscle fatigue between Weight Lifters(WL) and Non-Weight Lifters(NWL). There were twelve normal healthy adult volunteers, ranging in age from 18 to 35 years. The group consisted of six NWL and six WL. Randomized cross-over design was set up and work-rest cycle was 8 minutes work and 1 minute rest based on 15% MVC. Muscle fatigue was measured by the amount of force produced by the wrist flexor muscle and EMG amplitude over time. Repeated measures ANOVAs($2{\times}4$) were used to determine two types of subjects(WL, NWL) during four different duration of exercises(16, 32, 48, 64 minutes). The force decreased over time in NWL and WL, but there was no significant difference(F=2.83, p>0.05). However, the EMG amplitude increased in WL(0.8200) and NWL(0.6348). The WL exhibited an increase in EMG at the end of the period, especially at 48 minutes of exercises than did the NWL(F=9.58, p<.05). This suggests the WL were able to adjust to prolonged effort with adaptations in neural effect over time, resulting in higher EMG amplitude. That is, WL may be able to learn to recruit more motor units with training. It is important to the degree of neuromuscular fatigue and the time needed for recovery may differ considerably between WL and NWL, there is a need to plan proper strength training or rehabilitation protocols to match with the requirements in different characteristics of groups.
Objective : Localized vibration has been shown to have a positive effect on recovery of upper-limb motor function in patients with hemiparetic stroke, but there has been little research on kinematic analysis for qualitative changes in movement. This study investigated kinematic changes in elbow motion during reaching after localized vibration in persons with hemiparetic stroke. Methods : This study used a one-group, cross-over trial design. Ten chronic stroke patients randomly received localized vibrations on the affected biceps brachii for 5, 10, or 20 min, at 70 Hz. Kinematic analysis of reaching was measured using a 3-D motion analysis system. Variables included peak angular velocity, time to peak angular velocity, and movement units during elbow motion. Result : Affected side elbow motion during reaching was faster, smoother, and more efficient after 20 min localized vibration. Peak angular velocity increased (p<0.05), and time to peak angular velocity (p<0.05) and the movement unit were significantly decreased (p<0.05) during elbow motion for reaching. Conclusion : Localized vibration can improve kinematic components during reaching motion in persons with hemiparetic stroke.

A 5-year old, intact male, Cocker spaniel dog was referred with paraplegia and loss of deep pain perception. Physical, neurological examinations, radiography, and computed tomography were evaluated. Based on the clinical examinations, the dog was diagnosed with severe disc herniation ($L_2$ to $L_3$ intervertebral disc space). On the next day of presentation (6 days after loss of deep pain perception), hemilaminectomy was performed. After decompression of spinal cord and removal of herniated disc materials, $1{\times}10^6$ canine allogenic adipose tissue-derived mesenchymal stem cells (MSCs) diluted by $50{\mu}l$ saline were directly applied to the injured site of the spinal cord. Ten weeks of follow-up after surgery, full recovery of deep pain perception and motor function were evaluated in both hind limbs. Based on the result, we suggest that the transplantation of allogenic adipose tissue-derived MSCs to dogs with spinal cord injuries could be a considerable method to expect better clinical outcomes in veterinary practice.
Since 1960's along with industrialization and urbanization, economic growth has been . achieved, however, at the same time, environmental condition has been seriously deteriorated. . Currently, volume of wastewater has been increasing at annual rate of 7% in sewage and 20% in industrial wastewater. However, the nation's sewage treatment serves only 33% of the municipal wastewater as of 1991. Major portion of air pollutants comes from combustion of oil and coal which comprise 81% of total energy use and emission gases from motor vehicles increasing at an accelerated rate. It is known that Korea generates the highest amount of waste per capta. Nevertheless, it is not sufficient to reduce the volume of waste by means of resources recovery and recycling. Recognizing the importance of global environmental problems such as ozone layer depletion, global warming and acid rain, international society has been making various efforts since the 1972 Stockholm conference. In particular, it is expected that the Rio conference which has adopted the Rio declaration and Agenda 21 will form a crucial turning point of the emerging new world order after the Cold War confrontation. To cope with such issues as domestic pollution and global environmental problems, the fundamental national policy aims at harmonizing "environmental protection and sustainable development". The Ministry of Environment has recently set up a mid-term comprehensive plan which includes annual targets for environmental protection. According to the government plan, gradual improvement of various environmental conditions and specific measures to achieve them is planned in time frame. Additional sewage treatment plants will be constructed in urban areas with the target to treat 65% of the nation's municipal sewage by 1996. Supply of clean fuels such as LNG will also be expanded starting from large cities as a cleaner substitute energy for coal and oil. In parallel with expansion of LNG, emphasis will be placed on installation of stack monitoring system. Due to the relatively limited land, government's basic policy for solid waste treatment is to develop large scale landfill facilities rather than small sized ones. Thirty three regional areas have been designated for the purpose of waste management. For each of these regions, big scale landfill site is going to be developed. To increase the rate of waste recycling the government is planning to reinforce separate collection system and to provide industries with economic incentives. As a part of meeting the changing situation on global environmental problems after UNCED, and accommodation regulatory measures stipulated in the global environmental conventions and protocols, national policy will try to alter industrial and economic structure so as to mitigate the increasing trends of energy consumption, by encouraging energy conservation and efficiency. In this regard, more attention will be given to the policy on the development of the cleaner technology. Ultimately, these policies and programs will contribute greatly to improving the current state of national public health.
The effect of the developed symmetric upper extremity motion trainer on the cortical activation pattern was investigated in three chronic hemiparetic patients using both fMRI and Fugl-Meyer test. The training program was performed at 1 hr/day, 5 days/week during 6 weeks. Fugl-Meyer tests were performed every two weeks during the training. fMRI was performed at 3T scanner with wrist flexion-extension in two different tasks before and after the training program: the only unaffected hand movement (Task 1) and passive movements of affected hand by the active movement of unaffected hand (Task 2). fMRI studies in Task 1 showed that cortical activations decreased in ipsilateral SMC but increased in contralateral SMC. Task 2 showed cortical reorganizations in bilateral SMC, PMA and SMA. Therefore, it seems that the cortical reorganization in chronic hemiparetic patients can be induced by the training with the developed symmetric upper extremity motion trainer.
Facial nerve is subject to injury at any point in the course from the cerebral cortex to the motor end plate in the face, so many etiologic varieties of facial paralysis may be encountered, including trauma, viral infection and the idiopathic. Authors have studied 39 cases of facial paralysis which had experienced of treatment in our department from March, 1996 to March, 1997 at Dong San Medical Center. The results obtained are as follows : 1) The highest age incidence showed 10 cases(24.6%) in 3rd decade 2) Among the total of 39 cases, male were 21 cases(53.8%) and female were 18cases(46.2%). 3) At the involved side, left side were 19 cases(48.7%) and right side were 18 cases(46.2%). 4) The causes of facial paralysis were; idiopathic (Bell's palsy) in 19 cases(48.7%) infectious in 6 cases(15.4%) neoplastic in 6 cases(15.4%) traumatic in 5 cases(12.9%) metabolic in 2 cases(5.1%) congenital in 1 cases(2.6%) 5) In time interval between onset of symptom and treated initial date, 26 cases(66.7%) in below 10 days and 8 cases(20.5%) in 11-20 days 6) Correlation of recovery rate according to the treated duration did not differ significantly 7)Result after treatment were satisfactory
Objectives : This study was designed to evaluate the effects of Ohyaksungi-san(Wuyaoshungi-san) and Jungsongouhyul pharmacopuncture on pain reduction and nerve regeneration after crush injury in rat sciatic nerve. Methods : Animal model was produced through crush injury of right sciatic nerve and they were divided into four groups; Group I: no treatment control group; Group II: experimental group treated with Ohyaksungi-san(Wuyaoshungi-san); Group III: experimental group treated with Jungsongouhyul pharmacopuncture; Group IV: experimental group treated with Ohyaksungi-san(Wuyaoshungi-san) and Jungsongouhyul pharmacopuncture. For the assessment of pain, this study was observed the paw withdrawal latency(PWL) and immunoreactivity on the substance-P. For the assessment of nerve regeneration, the sciatic functional index(SFI) and immunoreactivity on the BDNF were measured. Results : 1. In the assessment of pain, the PWL of experimental groups was significantly higher than control group and group IV was significantly higher than other groups at the all days. 2. In immunohistochemical response of substance-P, as time passes, the immunoreactivity of all groups were decreased gradully. Especially, group IV had the lowest immunoreactivity. 3. In the assessment of SFI, the SFI of experimental groups were significantly higher than control group. 4. In immunohistochemical response of BDNF, the BDNF immunoreactivity of all groups was significantly higher than control group and especially, group IV had the highest immunoreactivity at the 14 days after injury. 5. H & E stain was used on the liver and kidney to investigate toxic effect of Jungsongouhyul pharmacopuncture and Ohyaksungi-san(Wuyaoshungi-san) on on 21 days after injury. However there were no any toxic effects both control group and experimental groups. Conclusions : On the basis of these results, we propose that Ohyaksungi-san(Wuyaoshungi-san) and Jungsongouhyul pharmacopuncture were related to pain reduction and motor nerve recovery, also decreased substance-P expression and increased BDNF expression after crush injury of sciatic nerve, especially these two treatments could be more effective when they were combined simultaneously.
