Objectives : Sarcopenia is a disease that leads to a decrease in skeletal muscle, and the importance of prevention and treatment thereof is increasing in an aging society. However, there is a definite limitation of exercise therapy for sarcopenia, and thus, there is an urgent need for a pharmacologic research to the treatment of sarcopenia. Methods : 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay was performed to confirm the antioxidant efficacy of water extract of Lacca Sinica Exsiccata (WELSE). To determine the effect of WELSE on myoblast activity, 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay was performed. To confirm the effect of WELSE on the differentiation of myoblast into myotubes, protein expression levels of myosin heavy chain 3 (Myh3) and paired box 3/7 (pax3/7) were confirmed by immunoblot analysis. In addition, immunofluorescence microscopy was performed to confirm the effect on myotube formation of WELSE. Results : It was confirmed that WELSE had high antioxidant activity and showed no cytotoxicity to myoblast up to 200 ㎍/㎖ concentration. Myoblast was treated with WELSE at a concentration of 100 ㎍/㎖ and differentiated for 5 days. The expression of Myh3, which forms myotubes, was promoted and the morphology of myotubes was changed and Increasing the thickness. Conclusions : In this paper, we confirmed the excellent antioxidant efficacy of WELSE and positive effects on muscle differentiation and myotube formation. These results suggest valuable as a material for pharmaceutical research on the prevention and treatment of sarcopenia.

Purpose : The study aims to determine the effects of virtual and non-virtual realities in a normal person's mirror walk on gait characteristics. Methods : Twenty male adults (Age: 27.8 ± 5.8 years) participated in the study. Reflection markers were attached to the subjects for motion analysis, and they walked in virtual reality environments with mirrors by wearing goggles that showed them the virtual environments. After walking in virtual environments, the subjects walked in non-virtual environments with mirrors a certain distance away after taking a 5 min break. To prevent the order effect caused by the experiential difference of gait order, the subjects were randomly classified into groups of 10 and the order was differentiated. During each walk, an infrared camera was used to detect motion and the marker positions were saved in real time. Results : Comparison between the virtual and non-virtual reality mirror walks showed that the movable range of the leg joints (ankle, knee, and hip joints), body joints (sacroiliac and atlantoaxial joints), and arm joints (shoulder and wrist joints) significantly differed. Temporal characteristics showed that compared to non-virtual gaits, the virtual gaits were slower and the cycle time and double limb support time of virtual gaits were longer. Furthermore, spacial characteristics showed that compared to non-virtual gaits, virtual gaits had shorter steps and stride lengths and longer stride width and horizontally longer center of movement. Conclusion : The reduction in the joint movement in virtual reality compared to that in non-virtual reality is due to adverse effects on balance and efficiency during walking. Moreover, the spatiotemporal characteristics change based on the gait mechanisms for balance, exhibiting that virtual walks are more demanding than non-virtual walks. However, note that the subject group is a normal group with no abnormalities in gait and balance and it is unclear whether the decrease in performance is due to the environment or fear. Therefore, the effects of the subject group's improvement and fear on the results need to be analyzed in future studies.

PURPOSE: This study aimed to evaluate the correlation between executive function and gait evaluations for the elderly, and validate the obstacle gait evaluation as a cognitive impairment test tool. METHODS: This study was a cross-sectional design. 79 people aged 65 years or older were selected as subjects. The Korean version of the Mini-Mental State Examination (MMSE-KC) to evaluate overall cognitive function and the Trail Making Test (TMT) A, B to measure executive function were performed. The 4-meter walking speed test and the walking speed test while crossing over an obstacle were carried out to evaluate gait. The Spearman's correlation was used to measure the correlation between cognition and gait speed. RESULTS: There was no significant correlation between the 4 m gait speed and executive function( TMT-A (p = .056), TMT-B (p = .115)). However, there was a significant correlation between the 4 m gait speed and MMSE-KC (r = .277, p < .05). There was also a significant correlation between walking speed while crossing over an obstacle and all tests (MMSE-KC (r = .382, p < .01). TMT-A (r = -.327, p < .01), TMT-B (r = -.283, p < .05)). CONCLUSION: It was found that the gait speed while crossing over an obstacle was correlated with all cognitive function tests. Therefore, we suggest the use of the gait speed test while crossing over an obstacle rather than the simple gait test to diagnose cognitive decline.

PURPOSE: This study examined the effects of applying mat Pilates and kinesio taping on the craniovertebral angle and muscle activity of adults in their 20s with a forward head posture. METHODS: The subjects were 20 adults in their 20s with a forward head posture: 10 from the Mat Pilates group (MPG) and 10 from the Kinesio taping group (KTG). Each group received the intervention for four weeks. The craniovertebral angle and muscle activity were measured before and after the intervention. Statistical analysis of this study was performed using SPSS Ver. 23.0 for Windows was used, and the statistical significance level was set to α = .05. RESULTS: The change in the craniovertebral angle within each group was decreased significantly after the intervention for both MPG and KTG (p < .05), but there was no significant difference in the comparison result of the difference in the amount of change between each group (p > .05). The change in muscle activity within each group did not show any significant change before and after the intervention in all the MPG and KTG muscles (p > .05), and there was no significant difference in all variables for the difference in the amount of change between each group (p > .05). CONCLUSION: Mat Pilates effectively reduced the CVA, but neither intervention significantly affected muscle activity.

BACKGROUND/OBJECTIVES: The prevalence of diabetes has continued to increase globally. Changes in eating habits, lack of exercise, increased stress, and aging are major contributors. Glycemic control is the key strategy of diabetes management. The purpose of this study was to analyze the utilization of nutrition labels and related factors among patients with diabetes. MATERIALS/METHODS: Data from the 7th Korea National Health and Nutrition Examination Survey were used. General, health-related, diabetes-related characteristics from 1,587 adults with diabetes history were included. Nutrition label utilization was assessed with awareness and use of nutrition labels and effects on food choice. For statistical analyses, chi-square test and multiple logistic regression analysis were performed. RESULTS: The prevalence of awareness, use, and effects of nutrition labels on food choice among diabetic patients were 48.8%, 11.4%, and 9.6%, respectively. High monthly income, walking frequency, family history of diabetes, younger age at diagnosis, and shorter duration of diabetes were associated with higher nutrition label awareness. Nutrition label use and effect on food choice were higher in women, those with high monthly income, those diagnosed at younger than 45 yrs, those with diabetes for less than 10 yrs, those with meal therapy, or patients who had undergone a fundus examination. CONCLUSIONS: Nutrition label utilization status was low in Korean patients with diabetes. Strategies are needed to promote nutrition label use as a diet management tool for patients with diabetes.

본 연구의 목적은 성숙한 당나귀의 큰잘록 창자 폐색 증례를 진단하여 보고하고자 한다. 당나귀(Equus africanus asinus; 암, 6세) 1마리가 제주경마공원 동물병원에 전날부터 시작된 식욕부진 증상으로 내원하였다. 장음소실, 탈수, 심한 복강 확장 등의 증상을 확인하였으나 호흡수 및 심박수는 정상이었고, 복통 증상은 없었다. 직장검사에서 폐색된 부분이 잘록 창자임을 확인하였다. 위세척, 수액요법 및 비스테로이드 계열의 진통제를 투여하였으나 다음날 새벽 갑자기 몸을 떨며 기립곤란과 같이 신체상태가 악화되기 시작한지 2시간 만에 폐사하였다. 부검에서 특히 왼배쪽 잘록 창자와 같은 큰잘록 창자에서 다량의 식괴를 발견하였고, 막창자와 곧창자는 정상이었다. 당나귀는 내원하기 11일 전에 새로 입사해서 사양 관리체계가 바뀌었다. 사료변경, 수분섭취 감소, 운동부족 등이 질병을 유발하였을 것으로 생각된다. 그러나 당나귀의 정확한 급사원인은 더 연구해야 할 과제로 남는다.
