Systemic lupus erythematosus(SLE) is an autoimmune disease which may affect many different organs and disclose various clinical manifestations. Recently central nervous system(CNS) involvement has been recognized as an increasingly significant contributor to morbidity and mortality of SLE. The clinical manifestations of CNS-lupus are highly variable and range from mild cognitive dysfunction, movement disorder, headache, psychosis to life-threatening stroke and coma. Among the neuropsychiatric disorders encountered in patients with SLE, cerebrovascular disease has been a relatively rare complication. The diagnosis and management of CNS-lupus is difficult because of the lack of useful diagnostic methods. If cerebrovascular involvement is suspected, aggressive treatment such as high dose steroid, immunosuppressive therapy, plasma exchange may be required to reduce high mortality rate. We experienced 2 cases cerebrovascular dis eases occurring in SLE patients which presented with various neuropsychiatric manifestations. They were diagnosed as CNS-lupus by neuropsychiatric symptoms, brain MRI, and BEG, and showed good response to high dose steroid pulse therapy.

Arthrography of the temporomandibular joint is a useful method of demonstrating the soft tissue abnormalities related to disc dysfunction. In this study, 19 asymptomatic joints, 31 joints with anterior disc displacement with reduction, 31 joints with anterior disc displacement without reduction which were classified by arthrotomography under fluoroscopy were evaluated to determine the linear measurement of anterior recess of inferior joint space and the relationship between the condylar anterior translation and the severity of the internal derangements. Their fluoroscopic images were also evaluated to describe the characteristics of condylar paths in internal derangements of the temporomandibular joints. The results were as follows; 1. The mean lengths of the anterior recess in asymptomaic group. reduction group. and non-reduction group were 8.7±1.6㎜. 11.2±1.7㎜, 12.8±1.7㎜ respectively. The length of the anterior recess was increased according to the severity of the internal derangements(P<0.05). 2. Linear measurements of anterior movement of condyle on maximum mouth opening were 13.1 ±4.2㎜, 15.9±4.1㎜, 5.0±3.7㎜ in asymptomatic group. reduction group, and non-reduction group respectively. Compared with asymptomatic group, reduction group showed hypermobolity of the condyle and non-reduction group showed hypomobility. 3. Condyles moved beyond the crest of articular eminence in 80% of reduction group and did not reach it in 70% of non-reduction group. 4. The condyle moved mainly superiorly in reduction group(66%) and horizontally in asymptomatic group(47%). There were no cases to move superiorly in non-reduction group.

Handwriting identifications are often faced with difficulties in evaluating handwriting by persons under the influence of alcohol. Cerebellar dysfunction is associated with deficits in the control of movement extent, as well as changes in the amplitude and relative amounts of acceleration and deceleration and action tremor. Although numerous articles are available on the subject of alcohol influence on handwriting quality, most of them were based on empirical data such as experience method, without any statistical evaluation. In this study, Hangul signature giyeok and nieun of consonant were measured in samples of handwriting. The result of this study can be used as a basic data of comparison on handwriting by identifying consistency of features and relative individualization of.

Background: Individuals with mechanical neck pain show biomechanical and neurophysiological changes, including cervical spine muscle weakness. As a result of deep muscle weakness, it causes stability disability and reduced upper thoracic spine mobility, which finally leads to functional movement restriction such as limited range of motion and dysfunction. Recent studies have shown that thoracic spine manipulation and mobilization could reduce symptoms of mechanical neck pain in patients. Objects: The purpose of this study was to investigate the effects of thoracic mobility exercise on cervicothoracic function, posture feature, and pain intensity in individuals with mechanical neck pain. Methods: The study subjects were 26 persons who were randomly assigned to the experimental (with thoracic mobility exercise) and control groups (without thoracic mobility exercise), with 13 subjects in each group. The cervicothoracic function (neck functional disability level and cervicothoracic range of motion), posture feature, and pain rating (using a quadrupled visual analogue scale [QVAS]) were measured before, after 3 weeks, and after 6 weeks. Results: Statistically significant group-by-time interactions were found with repeated analyses of variance for the Korean neck disability index (KNDI), all cervical range of motion (CROM), all thoracic range of motion (TROM), cranial rotation angle, sagittal shoulder posture (SSP), and QVAS (p<.05). All groups showed significant improvements from all times in all the evaluated methods. The KNDI, CROM, TROM of left rotation, and SSP in the experimental group showed significant improvements after 3 weeks, and the TROM of the right rotation and QVAS in the experimental group showed significant improvements after 6 weeks when compared with the control group. Conclusion: Thoracic mobility exercise during 6 weeks might be effective intervention to improve the functional level, posture feature, and QVAS pain rating for managing individuals with mechanical neck pain.

This study is for the elderly with mental and physical dysfunction, developing resistance exercise program using tube elasticity, and analysing the effects of this movement on the improvement of gait ability, balance ability and muscle strength of the elderly. After a 12-week program for 58 participants of the daycare center, dependent t-test was performed. As a result, the total participants showed average improvement in gait, balancing and hand grip strength. This means a lot in terms of improving one's ability of ADL(Activities of daily living) and reducing the risk of falling. Therefore, if the program expands and activates the target as an entire elderly, it is expected to be a preventative way to prevent healthy elderly people from moving to the frailty who need treatment and to delay the deterioration of the frailty with disabilities.

Purpose : This study's purpose is consideration about change of the hand grip strength according to different posture and shoulder flexion angle. The shoulder joint permits the greatest mobility and carries out the important function of stabilization for hand use. Hand grip activity is important to evaluate while assessing loads of shoulder in hand mobilities. Methods : Thirty(15 male, 15 female) college students with unknown shoulder dysfunction participated subject in five different positions of elbow extension with sitting and standing posture, different positions is followed : (1) shoulder $0^{\circ}$ flexion (2) shoulder $45^{\circ}$ flexion (3) shoulder $90^{\circ}$ flexion (4) shoulder $135^{\circ}$ flexion (5) shoulder $180^{\circ}$ flexion. Results : On the average, in the hand grip strength, the standing posture is higher than sitting posture. Sitting posture showed a most high level at the man's $0^{\circ}$ and woman's $135^{\circ}$. And standing posture showed a most high level at the man's $135^{\circ}$ and woman's $90^{\circ}$. Conclusion : The paired t-test was used to determine the different in grip strength between sitting and standing posture by shoulder angle change. There was no significant difference between the five position by sitting and standing posture. In man, correlation analysis revealed significant connection for all five position by sitting and standing posture. And in woman, correlation analysis revealed connection for all five position by sitting and standing posture.

Purpose: Balance and gait dysfunction caused by aging affect elderly individuals' independent life, which, in turn, can reduce their overall quality of life. The purpose of this study is to compare the differences in the vestibular function of healthy elderly and young adults based on the subjective visual vertical (SVV) test as well as to compare and analyze the gait ability between these two groups to study the differences and association between vestibular, dizziness, and balance ability. Methods: The subjects were 18 young and 16 elderly adults with no neurological or musculoskeletal damage. To evaluate vestibular function, a subjective visual vertical test was performed. To evaluate the gait function, the step time, step length, stride length, stance phase ratio, and swing phase ratio were measured. Balance was evaluated using the Berg Balance Scale (BBS), and dizziness was evaluated using a dizziness handicap inventory (DHI). Results: There were significant differences in the SVV, BBS, and DHI between the young and elderly adults (p < 0.05). The gait variables of the older adults were all significantly different (except for the swing phase ratio) than those of the young adults (p < 0.05). As the result of correlation analysis, the SVV values of the young adults showed a significant negative correlation with step length and stride length (p < 0.05), while the SVV values of the elderly adults only showed a significant positive correlation with the DHI (p < 0.05). Conclusion: The elderly appeared to show a decrease in vestibular function when compared to the young adults, and it is thought that walking and balance function declined, while dizziness increased. Moreover, it is believed that these results can be used as basic data for vestibular rehabilitation in the future.

Objective: There are many cases of applying various taping methods to prevent muscle damage and to assist with movement. The purpose of this study was to investigate and to compare the effects of dynamic taping on joint position sense and to find out the difference in error values during various degrees of shoulder flexion. Design: Cross-sectional study. Methods: A total of 20 subjects participated in this study with a randomized cross-over design. The order of taping was adjusted by randomly proceeding with dynamic taping, sham taping, and no taping. After the taping, the proprioception of the shoulder joint was evaluated. The evaluation of proprioceptive sensation was performed by evaluating joint position sensation. The sequence was adjusted by randomly performing joint position tests at each shoulder flexion of 50, 90, and 110 degrees. All angles were repeated 3 times. Results: There was a significant difference between dynamic taping and no taping in 50 degrees of shoulder flexion. There was a significant difference between sham taping and no taping in 90 degrees of shoulder flexion (p<0.05). No significant difference was found in 110 degrees of shoulder flexion. Conclusions: In this study, it was confirmed that dynamic taping is effective in improving the joint position sense in 50 degrees of shoulder flexion. In the future, it is expected that further studies will be conducted on patients with shoulder dysfunction with decreased proprioception.

For the toxicological pathologic study of amanita muscaria, we have investigated single and repeated dose toxicity in Sprague-Dawley (SD) rats. Single dose toxicity study was identified as catalepsy, incline and tail pinch methods (control 0 mg/kg, low 3.3 mg/kg, middle 16.5 mg/kg, high 33.0 mg/kg). Repeated dose toxicity study was carried out in blood tests, serum tests and histopathological methods. Neurotoxicity - muscle paralysis, and convulsion and loss of movement - was observed at 33.0 mg/kg group in the single dose toxicity study. Dysfunction of liver and kidney were shown in the repeated oral administration of the amanita muscaria at 3${\sim}$4 weeks. Serum chemistry results revealed a marked increase of LDH [Lactate Dehydrogenase (3181.5 IU/L; normal 230-460 IU/l)], ALT [Alanine transaminase (124.0 IU/l; normal <40 IU/l)] but the kidney was normal. Histopathological results show interstitial edema and tubular epithelial necrosis in the kidney. These results suggest that amanita muscaria has a neurotoxic effect and causes dysfunction of liver and kidney in the SD rat.
