This research has been conducted to provide the spinal cord injured patients with comprehensive necessity of and backup data for their rehabilitation in the community and make the aware of importance of overall community support to patients. The data was collected through questionnaire made to 83 patients charged to general hospital in Jeonbuk Province between 1 and 31 March 1997 to analyse the patients ability on activities of daily living through the research on general characteristics and Modified Barthel Index(MBI). As a result the outcome of the research was as follows : 1. Sexual distribution represented that 57 male (68.7%) and 26 female(31.3%) and in the age distribution majority group was 36 thirties (43.4 %) most active in social activities. 2. Analysis on occupation of patients showed majority group was in technicians, 21 people representing 25.4 % and the major cause of injury was traffic accident, 45people representing 54.2%, fall down, 17 people representing 20.5% and industrial accident, 13 people representing 15.7%, respectively. 3. In the multiple choice questionnaire on complications, the rate of appealing pain was highest and spasticity, pressure sore, contracture, depression which restrict the patients from activities of daily living ability were also appeared. 4. The theoretical points in MBI Should lie between 1 and 115 and the average point be 58 but the average point of the MBI among 83 patients was 63. 5. The MBI point by the level of injured represented statistically critical difference(P<0.001) and the MBI points tested by Duncan's Multiple Area Testing in lumbar(80.1) and in thoracic (65.8) represented critically higher than the one in cervical(42.5). 6. In the distribution of the method of Urination after spine injury, the intermittent catheterization represented highest numbar of 34(41.1 %). Testing by Duncan's Multiple Area Testing, as we found the critical difference in the analysis on MBI points(P<0.001), the point in independent self voiding patients ($90.87{\pm}29.34$) was higher than the one in other self voiding patients(P<0.05). 7. In th category of social activities after spine injury, the number of people classified in others, 41 people representing 49.5% was highest and in the MBI points of the spinal cord injured people in religious activity, hobby activity, private club, occupation was critically higher than the people classified in miscellancous(P<0.01) who are the spinal cord injured people and mostly depend on their family's assistance at home in their daily activities.

Purpose In this study, We observed the recovery process in the ability to move in the hind limbs of the rats whose spinal cord injuries were treated by Radix acouniti(RA). The purpose of this study is to see the effects of Radix acouniti(RA) water extract on the contraction of rat's spinal cord injury. Procedure First, the rats were subjected to hemisectional spinal cord injuries by a scalpel blade. Those rats, then, were divided into three groups: Sham operated rats group and the experimental group, which received the Radix acouniti(RA) water extract, and the control group, which had no treatment. Their recovery in the ability to walk was observed by the Open Field Test (OFT) for 14 days after the injuries. Method The OFT was applied at four points: the hip, knee, ankle joint, and the tail. Each joint was given a movement rating of from 0 to 3, depending on the amount of movement. A movement rating of 0 designates no movement, a 1 designates slight movement, a 2 designates increased movement, and a 3 designates active movement. Slight movement is defined as a joint displaying less than or equal to 30% of that joint range, increased movement is displaying less than or equal to 60% of that joint's range, and active movement is greater than or equal to 90% of that joint's range. Tail movement is also graded on a scale of 0 to 3. A rating of 0 indicates that the tail is down 100% of the time, one of 1 indicates that the tail is down more than 10%, one of 2 shows that the tail is down less than 50% but more than 10% of the time, and one of 3 shows that the tail is down less than 10% of the time. All four ratings were added together and then averaged to arrive at a single score. Results The sham group which did not go through spinal cord injuries showed near normal results on all 3 joints and tail from right after the operation, which one would expect. The RA oral application group showed more effective recovery of movememt function than the control group around 4 days after the spinal cord injuries. However, after 14 days, both groups displayed almost the same degree of movement recovery. The results of this study are summarized as follows: 1. After 14days the spinal cord injuries, movement was recovered in sham operated group, control group, and experimented group in the hip, the knee, the tail and then the ankle of rats, in that order. 2. Around 7 days after the spinal cord injuries, the experimental group proved the effectiveness of the therapy in terms of movement recovery. 3. The level of ALT, ALP, AST in RA treated group was slightly increased. 4. The level of BUN and creatinine in RA treated group was slightly increased. The above results indicate that RA therapy at an early stage can bring about better movement recovery in patients with spinal cord injuries from traffic accidents or industrial disasters. But there is apparent side effect of RA on clinical, therefore the study on this should be continued.

Objectives: This study aimed to compare the gait patterns of cerebellar infarction patients with those of corticospinal tract stroke patients through a follow-up of patients with ataxic gait due to cerebellar infarction and corticospinal tract stroke. Methods: We investigated two cases of patients with cerebellar infarction and two cases each of acute or chronic corticospinal tract stroke who were hospitalized at Wonkwang University Gawangju Medical Center from September 1, 2017 to February 15, 2020 based on medical records and gait analyses. The spatiotemporal gait parameters of each patient were measured three times at 2-week intervals except those of the chronic corticospinal tract stroke patients, which were measured twice at a 1-month interval. Results: Spatiotemporal gait parameters, which include velocity, cadence, step length, stride length, and single support, were consistently increased in the cerebellar infarction patients in comparison to the corticospinal tract stroke patients. The stance phase was decreased in all the patients. Conclusions: The cerebellar infarction patients' gait spatiotemporal parameters were found to consistently improve. Moreover, gait analysis can be used to effectively measure improvement of ataxic gait.

Purpose: This study aimed to compare the effect on nerve regeneration of ultrasound irradiation in rats with peripheral nerve injury. Methods: To investigate alterations of the NCAM immunoreactivity in non-crushed part and crushed part of the spinal cord, the unilateral sciatic nerve of the rats were crushed. The expression of NCAM was used as the marked of peripheral nerve regeneration, and also plays an important role in developing nerve system. Experimental animals were sacrificed by perfusion fixation at post-injury 1, 3, 7, 14 days after ultrasound irradiation. The pulsed US was applied at a frequency of 1MHz and a spatial average-temporal average Intensity of 0.5W/of (20% pulse ratio) for 1 mins. The Luxol fast blue-cresyl violet stain were also done to observe the morphological changes. Results: Alteration of NCAM immunoreactivity in the crushed part and the non-crushed part of lower lumbar spinal cord were observed. NCAM-immunoreactivity cells were some increased in the dorsal horn lamina I, III and cell ventral horn at 1 day after unilateral sciatic nerve injury. However, there was not significant difference in the relationship between crushed part and non-crushed part. NCAM-inmmunoreactivity was remarkably increased at 3 days after unilateral sciatic nerve injuryin the gray matter and white matter. NCAM-immunoreactivity was increased in the ventral horn and post horn of experimental crushed part. Also, NCAM-immunoreactivity in large motor neurons in ventral horns lamina VIII, IX were increased at 7 days after unilateral sciatic nerve injury. At 14 days after sciatic nerve crushed injury, there was no significant difference. All group were decreased for 14 days. In the time course of NCAM expression, all groups showed a significant difference at 3day groups(p<0.05). Whereas, CC group was noted a significant difference between 3day and 7 day group respectively. In NCAM expression, there were significantly increased in all group. In the relationship between CNC group and ENC group, significant difference was detected among 3, 7, 14 day group(p<0.05). The difference between CC group and ENC group were noted in all groups(p<0.05). Conclusion: It is consequently suggested that the effects of the ultrasound irradiation may increase the NCAM immunoreactive neurons and glial cell in the spinal cord after unilateral sciatic nerve crushed injury. Therefore, the increased NCAM immunoreactivity in the spinal cord may reflect the neuronal damage and healing process induced by a ultrasound irradiation after peripheral nerve injury in rat.

Background: Zaprinast is an inhibitor of phosphodiesterase 5, 6 and 9. Phosphodiesterase inhibitors could produce anti-nociceptive effects by promoting the accumulation of cGMP. We hypothesized that intrathecal zaprinast could attenuate the allodynia induced by chronic constriction injury of the sciatic nerve in rat. Methods: Sprague-Dawley rats were prepared with four loose ligations of the left sciatic nerve just proximal to the trifurcation into the sural, peroneal and tibial nerve branches. Tactile allodynia was measured by applying von Frey filaments to the lesioned hindpaw. The thresholds for the withdrawal responses were assessed. Zaprinast ($3-100{\mu}g$) was administered intrathecally by the direct lumbar puncture method to obtain the dose-response curve and the 50% effective dose ($ED_{50}$). Measurements were taken before and 15, 30, 45, 60, 90, 120, and 180 min after the intrathecal doses of zaprinast. The side effects were also observed. Results: Intrathecal zaprinast resulted in a dose-dependent antiallodynic effect. The maximal effects occurred within 15-30 min and then they gradually decreased down to the baseline level over time in all the groups. There was a dose dependent increase in the magnitude and duration of the effect. The $ED_{50}$ value was $17.4{\mu}g$ (95% confidence intervals; $14.7-20.5{\mu}g$). No severe motor weakness or sedation was observed in any of the rats. Conclusions: Intrathecally administered zaprinast produced a dose-dependent antiallodynic effect in the chronic constriction injury neuropathic pain model. These findings suggest that spinal phosphodiesterase 5, 6 and 9 may play an important role in the modulation of neuropathic pain.

Peripheral nerve injury sometimes leads to neuropathic pain and depletion of calcitonin gene related-peptide (CGRP) and substance P (SP) in the spinal cord. However, the pathophysiological mechanisms for depletion of CGRP and SP following the neurorathic injury are still unknown. This study was performed to see whether the distribution of immunoreactivity for CGRP and SP in the superficial dorsal horn and dorsal root ganglia(DRG) was related to the distance between the DRG and injury site. To this aim, we compared two groups of rats; one group was subjected to unilateral inferior and superior caudal trunk transections at the level between the S3 and S4 spinal nerves (S34 group) and the other group at the levels between the S1 and S2, between S2 and S3 and between S3 and S4 spinal nerve (S123 group). The transections in both groups equally eliminated the inputs from the tail to the S1-3 DRG, but the distance from the S1/S2 DRG to the injury site was different between the two groups. Immunostaining with SP and CGRP antibody was done in the S1-S3 spinal cord and DRG of the two groups 1 and 12 weeks after the injury. The results obtained are as follows: 1. The immunoreactivity for CGRP and SP in the ipsilateral superficial dorsal horn and DRG decreased 1 and 12 weeks after neuropathic nerve injury. 2. The immunoreactive area of SP and CGRP in the S1 dorsal horn was smaller in the S123 group than in the S34 group, whereas that in the S3 dorsal horn was not significantly different between the two groups. The number of SP-immunoreactive DRG cells decreased on the neuropathic side as compared to the sham group's in all DRGs of experimental groups except the S1 DRG of the S34 group. These results suggest that the amounts of SP and CGRP in the dorsal horn and DRG following neuropathic injury inversely decrease according to the distance between the DRG and injury site.

Purpose: Human adipose tissue-derived mesenchymal stem cells(hATSCs) can be differentiated into multiple mesenchymal lineages, including bone, cartilage, and muscle. And growth hormone play important roles in the normal growth and development of the CNS. In this study, we explored whether the transplanted hATSCs and growth hormones could improve functional recoveries from rats with contusive spinal cord injury. Methods: We divided 30 female rats, which were subjected to a weight driven implant spinal cord injury, into 3 groups with 10 rats each; Group A as a control group, group B with hATSCs transplantation on injured region, and group C with hATSCs transplantation and GH administration for 7 days. Then, we researched their neurologic functional recoveries before and 2, 4, and 8 weeks after transplantation using Basso-Beattie-Bresnahan (BBB) locomotor rating scale. And we checked Y-chromosome positive cells by FISH(Fluorescent in situ hybridization) to identify the survival of transplanted mesenchymal stem cells. Results: After 4 weeks of transplantation, the group B and group C showed significant improvement of neurologic function on BBB locomotor rating scale in comparison with the group A(Group A: $13.1{\pm}0.58$, Group B: $14.6{\pm}0.69$, Group C: $14.9{\pm}0.56$). Moreover, the group C displayed meaningful recovery of neurologic function after 8 weeks in comparison with group B (Group B: $15.7{\pm}0.63$, Group C: $16.5{\pm}1.14$). The group A, the control one, improved for 5 weeks after injury, and had no more recovery. On the other hand, Group B and C showed the improvement of neurologic function continuously for 9 weeks after injury. Conclusion: In this study, we found out that hATSCs transplantation have an effect on neurologic functional recovery of spinal cord injured rat and GH injection seems to bring the synergistic results on this good tendency.
