Cortex ulmi pumilae, the cortex of Ulmus davidiana var. japonica, has been used in traditional folk medicine for its anti-inflammatory effect. Although its various bioactivities such as anti-inflammatory, anti-microbial, and anti-cancer, have been reported, the anti-adipogenic activity of cortex ulmi pumilae remains unclarified. In the present study, we investigated the effect of cortex ulmi pumilae extract on adipocyte differentiation in 3T3-L1 preadipocytes. Treatment with cortex ulmi pumilae extract significantly reduced the formation of lipid droplets and triglyceride content in a dose-dependent manner; this is associated with an inhibition of the adipogenic transcription factors, CCAAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$), $C/EBP{\beta}$, and peroxisome proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$). In addition, cortex ulmi pumilae extract treatment during the early stage of adipogenesis showed more efficient anti-adipogenic activity than treatment during other stages of adipogenesis. Cortex ulmi pumilae extract also inhibited cell proliferation and induced G1 arrest of 3T3-L1 cells in the early stage of adipogenesis. This was associated with upregulated expression of Cdk inhibitor p21 and downregulated expression of cyclin E and phospho-Rb, indicating that cortex ulmi pumilae extract blocks mitotic clonal expansion by cell cycle regulation. Taken together, these results suggest that cortex ulmi pumilae extract possesses anti-adipogenic activity through the inhibition of adipocyte differentiation by blocking mitotic clonal expansion.

Purpose: Obesity has recently emerged as a significant health problem in the pediatric population, and the prevalence of non-alcoholic fatty liver disease is increasing in tandem with a significant rise in childhood obesity. Therefore, this study was conducted to clarify the risk factors of non-alcoholic steatohepatitis in obese children. Methods: We enrolled 84 obese children who visited the pediatric obesity clinic at Yeung-Nam university hospital. The patients were divided into two groups based on their alanine aminotransferase (ALT) level (separated at 40 IU/L), and the mean of ages, total cholesterol levels, HDL-cholesterol levels, LDL-cholesterol levels, triglyceride (TG) levels, as well as the mean obesity index, and body fat percentage of the two groups were then compared. Results: When the mean of ages ($10.5{\pm}1.6$ vs. $10.7{\pm}2.0$ years), total cholesterol levels ($183.0{\pm}29.1$ vs. $183.7{\pm}31.3$ mg/dL), HDL-cholesterol levels ($53.0{\pm}10.2$ vs. $55.7{\pm}13.0$ mg/dL), LDL-cholesterol levels ($113.4{\pm}30.2$ vs. $113.0{\pm}30.0$ mg/dL), triglyceride levels ($99.4{\pm}62.9$ vs. $114.2{\pm}47.3$ mg/dL), obesity indexes ($44.7{\pm}12.2$ vs. $47.9{\pm}15.1%$), and body fat percentages ($32.7{\pm}5.0$ vs. $34.0{\pm}4.8%$) of group 1 (ALT${\leq}$40 IU/L) were compared with those of group 2 (ALT${\geq}$41 IU/L), no significant differences were observed (p>0.05). However, hypertriglyceridemia (TG${\geq}$110 mg/dL) was more frequent in group 2 than in group 1 (p=0.023). Conclusion: TG may be an important risk factor in non-alcoholic steatohepatitis and further study regarding the risk factors in non-alcoholic steatohepatitis is required.

In order to design and develop a product that can treat the fatty liver, natural complex food with all natural ingredients was developed and supplemented to rats with high fat diet to induce fatty liver. As a result, when the amount of natural complex food was increased in diet of subjects, the activities of the blood serum AST, ALT, ALP, 3-GT and LDH were decreased. The total protein concentration levels of the 30% and the 50% natural complex food groups did not show changes in respect to the control group, but the 100% natural complex food groups showed significant decrease (p<0.05). Likewise, the amount of blood serum albumin in the 30% and the 50% natural complex food groups did not show improvement, but the 100% natural complex food did showed significant changes (p<0.05). The amount of blood serum triglyceride decreased as the amount of natural complex food was increased. In order to investigate the appearances of the accumulated fat in the liver, the animals were dissected. Livers of the control group (no natural complex food) were appeared as a white color, which means serious fat accumulation. However, all the natural complex food groups (30,50 and 100% natural complex food) showed noticeable decrease of fat content. Even the histology showed that livers of the control group had expansion of the fat, but a11 the natural complex food groups had e decreased as the contents and continued to show destroyed fatty cells. By observing the biological numeric data, the physical appearance and the history of the fatty liver, it is highly expected that natural complex food is very effective in treating the liver damaged -by the to fat and the cholesterol.

Purpose: Verifying a reliable predictor of the progression of vertebral deformity in patients with acute osteoporotic fractures of the lumbar spine may be useful. A qualitative analysis of the muscle near the spine was performed using magnetic resonance imaging (MRI), and its correlation with a spinal deformity was determined under the hypothesis that the causes of the kyphotic deformity are associated with muscle reduction in the multifidus and erector spinae. Materials and Methods: The study was performed in a retrospective manner using the electronic medical records of patients who presented to the author's institution between January 2007 and March 2018, and were diagnosed with an acute lumbar fracture. The fat infiltration rates of the multifidus and erector spinae were measured using MRI taken at the time of injury, and the mean value was defined as the total fat infiltration rate (TFI). Based on lateral radiographs of the lumbar spine at the one-year follow-up, the loss of height of the vertebral body, the kyphotic angle and the wedge angle were measured. The statistical significance was confirmed by calculating the Pearson correlation coefficient. Results: One hundred twenty-nine patients, of which 30 were male and 99 were female, were examined. The mean age was 71.28 years. The mean T-score was -3.53±0.79 g/cm², and the mean fat infiltration was 15.20%±11.99%. TFI was positively correlated with age (R=0.373, p<0.001), compression rate (R=0.369, p<0.001), and Cobb's angle (R=0.386, p<0.001) after a one year follow-up, but negatively correlated with the BMD score (R=-0.252, p=0.004). As the fracture progressed to the lower lumbar level, the compression rate (R=-0191, p=0.030) and wedge angle (R=-0.428, p<0.001) at the time of injury tended to decrease. Conclusion: In patients with osteoporotic vertebral fractures, the fat infiltration rate may be an important predictor of conservative treatment. The prognosis of patients with a high-fat infiltration rate should be explained during patient education, and the patients must be monitored closely through short-term outpatient follow-up.

목장 경영의 성공과 실패에는 여러 가지 요인이 작용하지만 연중 얼마나 적은 소가 도태되는가 하는 것 또한 아주 중요하게 생각해 보아야 할 사항이다. 낙농에 있어 거의 대부분의 질병이 산욕기에 발병하는데 산욕기(産褥期)란 분만으로 인한 상처가 완전히 낫고, 자궁이 평상시 상태가 되며 신체의 각기관이 임신 전의 상태로 회복되기까지의 기간으로 대개 분만 후 6~8주간을 말한다. 산욕기에 주로 발생할 수 있는 다양한 질병(산욕기 부전마비, 난산, 급성유방염, 제4위 전위증 등)들이 조기에 발견되어 적절히 치료되지 못하고 만성화되면서 전해질불균형, 에너지와 단백질의 섭취부족에 의한 영양장애로 허약과 지방간 및 케토시스 등으로 진행되어 결국 도태됨으로서 목장 경영에 있어 막대한 영향을 끼치는 것이다. 이러한 산욕기 질병의 주 원인은 건유기 사양관리에 있다. 건유기간 동안 체점수(BCS)의 변화를 최대한 줄이면서 분만전의 스트레스를 얼마만큼 줄일 수 있도록 관리하는가에 달려있다. 다시말해 분만 전 마지막 한달간에 건유에서 분만으로의 이행과정을 얼마나 매끄럽게 연결 지어주는가에 따라 산욕기 질병의 발생률이 결정되는 것이다. 본 고에서는 건유기 사양관리 소홀로 발생되는 산욕기 부전마비에 관해서 자세히 설명해 보고자 한다.

날로 광역화, 지능화, 디지털화된 범죄양상과 국민들의 고품질 치안서비스에 대한 관심과 욕구의 증대로 인해 치안수요가 증가하고 있다. 지금까지의 선행연구들은 경찰인력의 수요에 영향을 미치는 특정 변수를 회귀분석을 통해 찾아낸 뒤 이것을 바탕으로 경찰인력에 대한 예측을 시도하였으나, 경찰 업무 전반에 걸친 직무를 분석하여 치안 수요 및 업무량에 따른 적정인력을 산출하는 연구는 부족한 실정이다. 따라서 본 연구는 경찰관서 각 기능별 실무자 면담을 통해 직무를 분석한 후 기능별 주요 업무를 선정하였고 시스템 다이내믹스 방법론을 활용하여 기능별 경찰관서의 표준인력 수요를 예측하였다. 또한 235개의 관서 모델을 만들어 컴퓨터 시뮬레이션을 통해 관서별, 지방청별 효율적 인력 운용 방안에 대해 논의하였다.

We reported on a rare case of recurred macrodystrophia lipomatosa of the foot, and reviewed the literature. A 62-year-old male patient presented with right foot second toe pain; preoperative magnetic resonance imaging and radiograph examination was performed. After surgery the biopsy confirmed the diagnosis. American Orthopaedic Foot and Ankle Society score was checked before and after surgery. Wide excision of the affected area including ray amputation is an effective way to prevent recurrence and relieve the pain after surgery. The 2nd toe ray amputation was performed in the treatment of recurred macrodystrophia lipomatosa of the foot, and is thought to be an effective way to relieve pain and prevent recurrence. After minimally invasive surgery with complete excision surgery, additional data on recurrence and pain relief rate are needed.
