  • 풀사료를 주식으로 하며 자유롭게 방목되는 호주산 소와 곡물사료를 주식으로 하며 상대적으로 제한된 면적의 축사에서 사육되는 한국산 소의 두 가지 근육에서 디스트로핀 단백질 발현 수준을 비교하였다. 총 244 두의 식용소 도체로부터 양국에서 같은 부위의 골격근 조직을 채취하고 10% 중성 포르말린을 이용해 고정하였다. 본 연구에서 지방 침착률이 골격근 막 관련 단백질들의 소실과 밀접한 연관이 있다는 점을 발견하였는데, 특히 디스트로핀이 지방이 침착된 골격근에서 가장 유의적으로 감소하는 것을 확인하였다. 이와 동시에 CD36이 지방이 침착된 골격근에서 가장 풍부하게 발현하는 것도 확인하였다. 이렇게 정상 골격근의 구조를 유지하는 데 필요한 세포골격 단백질들의 소실에는 산화적 스트레스에서부터 사료의 종류에 따른 산화 지질 및 운동, 기후, 성장 기간 등의 환경에 이르기까지 다양한 사육 조건들이 영향을 미쳤을 것으로 여겨졌다. 디스트로핀은 근형질막 관련 단백질들 중에 근이영양증이나 근육 변성과 관계된 가장 민감한 막 단백질이다. 그러므로 본 연구는 사람의 근이영양증 관련 연구를 비롯해 동물모델을 이용하여 근육질환의 기전을 찾는 연구에도 중요한 초석이 될 것으로 보이며, 나아가 근이영양증 기전 규명을 위한 기초연구뿐만이 아니라 치료를 위한 실용화 연구에도 응용될 수 있을 것으로 사료된다.

  • Purpose: This quasi-experimental study was performed to investigate the effects of a health promotion program(HPP) on self-efficacy, healthy lifestyle and blood lipid profile in employees with hyperlipidemia. Methods: The subjects were forty-three employees who were diagnosed as having hyperlipidemia during routine health examination at two worksites in Seoul in 2001. Of the forty-three subjects, thirty were allocated to the experimental group and the remaining thirteen were allocated to the control group. Data were collected from September 24, 2001 to March 16, 2002. The HPP was applied to the experimental group for 11 weeks and included health education, diet counseling, watching videos, conference, and so on. The health education included information about exercise, smoking cessation, and abstinence from drinking alcohol and seven sessions of hyperlipidemia education. The experimental group was requested to keep a daily health promotion lifestyle diary. This diary was analyzed by a dietician and subjects were instructed based on the results. As for data analyses, wilcoxon signed rank test and wilcoxon rank sum test and x2-test were carried out using SAS program. Results: 1. Self-efficacy scores of the experimental group were significantly more increased than those of the control group (experimental: 5.86 10.80, control: -4.04 11.91, p=0.018). 2. Healthy lifestyle scores of the experimental group were significantly more increased than those of the control group (experimental: 0.19 0.26, control: -0.05 0.29, p=0.024). 3. Blood total cholesterol values of the experimental group were significantly more decreased than those of the control group (experimental: -13.07 30.10mg/dl, control: 10.00 26.57mg/dl, p=0.033). 4. Blood triglyceride values of the experimental group were significantly more decreased than those of the control group (experimental: -29.17 192.40mg/dl, control: 63.31 107.53mg/dl, p=0.050). Conclusion: These findings indicate that the HHP could be effective in improving self-efficacy, healthy lifestyle and blood HDL cholesterol and decreasing blood total cholesterol in employees with hyperlipidemia. Therefore, the HHP could be suggested as an effective nursing intervention for employees in the worksite by ultimately preventing cerebral and cardiac vessel complications related to hyperlipidemia.

  • Purpose: The purpose of this study was to investigate how induced microcurrent shoes influenced changes of the blood circulation in patients with Plantar Fasciitis. Methods: Initially, the subjects were comprised of 5 males and 5 females, who agreed with this research and are more than fifty years old, but 4 of those were dropped during the experiment. They all have plantar fasciitis and pain on their feet. Subjects wore the induced microcurrent shoes for more than 4 hours everyday during 4 weeks. When they wore those shoes, they also wore the specially produced shocks made of silver-mixed thread and they were asked to avoid intense exercise. Assessments were carried out before and after walking on a treadmill and we measured changes between the test before and after 4 weeks. In the examination of the before test, general shoes were used, and in the examination of the after test, induced microcurrent shoes were used. Temperature difference was measured by thermograpy DOREX spectrum 9000MB(USA). Subjects walked total 20 minutes and during gait, the walking rate on a treadmill was increased from 2Km/h to 3Km/h after 10 minutes. We measured plantar temperature by thermograpy especially both heel, 1st, and 5th metatarsal areas. Results: Firstly, in comparison of the blood circulation on the left and right foot at 0 week and 4 weeks, it tended toward increasing blood circulation but there was. no statistically significant difference (p>0.05). Secondly, in comparison of the blood circulation before and after treadmill with the induced microcurrent shoes, the blood circulation of the heel and the 5th area on the right foot was increased to all subjects(p<0.05). Conclusion: The results of this study revealed that subjects showed tendency to increase blood circulation in both right and left feet after wearing microcurrent shoes and specially after walking treadmill at 4 weeks. Therefore induced microcurrent shoes are useful to improve blood circulation for patients with plantar fasciitis.

  • Purpose : This study is intended to examine the motor skill learning on balance and coordination in the cerebellar injured rats by 3AP. Methods : This study selected 60 Sprague-Dawley rats of 8 weeks. Experiment groups were divided into four groups and assigned 15 rats to each group. Group I was a normal control group(induced by saline); Group II was a experimental control group(cerebellar injured by 3AP); Group III was a group of motor skill learning after cerebellar injured by 3AP; Group IV was a group of treadmill exercise after cerebellar injured by 3AP. In each group, motor performance test, histologic observations, synaptophysin expression and electron microscopy observation were analyzed. Results : In motor performance test, the outcome of group II was significantly lower than the group III, IV(especially group III)(p<.001). In histological finding, the experimental groups were destroy of dendrities and nucleus of cerebellar neurons. Group III, IV were decreased in degeneration of cerebellar neurons(especially group III). In immunohistochemistric response of synaptophysin in cerebellar cortex, experimental groups were decreased than group I. Group III's expression of synaptophysin was more increased than group II, IV. In electron microscopy finding, the experimental groups were degenerated of Purkinje cell. Conclusion : These result suggest that improved motor performance by motor skill learning after harmaline induced is associated with dynamically altered expression of synaptophysin in cerebellar cortex and that is related with synaptic plasticity.

  • Few studies investigated the effects of nutrition education and exercises in women with osteopenia. This study examined the relationship between changes in dietary intakes and changes in indicators related to bone health in postmenopausal women with osteopenia (-2.5 ${\leq}$ T-score ${\leq}$ 1) after a 12-week intervention. Thirty-one postmenopausal women aged > 50 years residing in Seoul were recruited and participated in nutritional education regarding bone health and general nutrition practices and aerobic exercises (three times a week; 60 min per session). Twenty-five subjects completed the study and were eligible for the analysis. Bone mineral density (BMD) at femoral neck was measured by dual energy x-ray absorptiometry. Serum calcium, osteocalcin, and intact parathyroid hormone (PTH) were also measured. Dietary intake was estimated by using a one-day 24 recall by a clinical dietitian. After 12 weeks, meat consumption increased (P = 0.028) but vegetable intake decreased (P = 0.005). Intakes of animal protein (P = 0.024), vitamin B1 (P = 0.012) and vitamin $B_2$ (P = 0.047) increased, and sodium intake decreased (P = 0.033). Intact PTH (P = 0.002) decreased and osteocalcin (P = 0.000) increased, however, BMD decreased (P = 0.000). Changes in mushroom consumption were positively correlated with femoral neck BMD (r = 0.673, P = 0.003). Changes in animal iron intake were negatively correlated with intact PTH (r = -0.488, P = 0.013) but were positively correlated with osteocalcin (r = 0.541, P = 0.005). These results suggested that the association between animal iron intake and biochemical markers of bone turnover may play an important role in bone metabolism. Further studies are needed to shed light on complicated mechanisms of diet, hormonal levels of bone metabolism, and bone density.

  • Purpose: Childhood obesity is an increasing public health issue worldwide. We examined dietary patterns among adolescents in a dormitory school, identified obese adolescents and tried to intervene to improve food habits and physical activity. Methods: We conducted an experimental prospective longitudinal study based on 36 obese (body mass index $[BMI]{\geq}95th$ percentile) adolescents (aged 12-18 years) compared with controls (healthy children: normal age-appropriate BMI ($BMI{\leq}85th$ percentile). Six months' intervention included lifestyle-modification counseling (once a week by a clinical dietician), and an exercise regimen twice a week, 60 minutes each time, instructed by a professional pediatric trainer). Both groups underwent baseline measurements at the beginning of the study and 6 months later (arterial stiffness, blood pressure, pulse, weight and height, hemoglobin, creatinine, liver enzymes, highly sensitive C-reactive protein and complete lipid profile). Results: Twenty-one participants completed the study. Low compliance from participants, school staff and parents was observed (participation in planned meetings; 71%-83%). BMI significantly decreased from $32.46{\pm}3.93kg/m^2$ to $30.32{\pm}3.4kg/m^2$ (P=0.002) in the study group. Arterial stiffness was not significantly different between the 2 groups and did not change significantly after 6 months' intervention (P=0.494). No significant changes in CRP and lipid profile were observed after the intervention. Conclusion: Making lifestyle modifications among adolescents in a dormitory school is a complex task. Active intervention indeed ameliorates BMI parameters. However, in order to maximize the beneficial effects, a multidisciplinary well-trained team is needed, with emphasis on integrating parents and the school environment.

  • Copy number variations (CNVs), important genetic factors for study of human diseases, may have as large of an effect on phenotype as do single nucleotide polymorphisms. Indeed, it is widely accepted that CNVs are associated with differential disease susceptibility. However, the relationships between CNVs and gene expression have not been characterized in the horse. In this study, we investigated the effects of copy number deletion in the blood and muscle transcriptomes of Thoroughbred racing horses. We identified a total of 1,246 CNVs of deletion polymorphisms using DNA re-sequencing data from 18 Thoroughbred racing horses. To discover the tendencies between CNV status and gene expression levels, we extracted CNVs of four Thoroughbred racing horses of which RNA sequencing was available. We found that 252 pairs of CNVs and genes were associated in the four horse samples. We did not observe a clear and consistent relationship between the deletion status of CNVs and gene expression levels before and after exercise in blood and muscle. However, we found some pairs of CNVs and associated genes that indicated relationships with gene expression levels: a positive relationship with genes responsible for membrane structure or cytoskeleton and a negative relationship with genes involved in disease. This study will lead to conceptual advances in understanding the relationship between CNVs and global gene expression in the horse.
