This research was performed to compare spinal segment motion angle between low back pain (LBP) group and painless group during trunk flexion-extension and to investigate the effect of transversus abdominis strengthening exercise on spinal segment motion angle in LBP group. Nine subjects with LBP and ten subjects without LBP participated. Transversus abdominis strengthening exercise was peformed in LBP group for three weeks, and spinal segment motion angles were compared before and after the exercise performance. Spinal segment motion angles were measured both in sitting and standing position. Results were as followed: 1) Subjects' average age was 24.79 years, height was 167.84 ㎝, and weight was 59.95 ㎏. 2) Spinal segment motion angle of T10/11 was significantly higher in LBP group compared with painless group (p<.05) in sitting position during trunk flexion-extension. 3) In sitting position, whereas entire lumbar segment motion angles were lower in LBP group compared with painless group (p<.05), angle of L4/5 was higher in LBP group compared with painless group (p<.05). 4) There was no significant difference in thoracic segment motion angle in standing position. 5) After three weeks of transversus abdominis strengthening exercise, thoracic segment motion angle increased both in sitting and standing position (p<.05). 6) In painless group, there was no significant difference in entire spinal segment motion angles in sitting and standing position (p>.05). When spinal segment motion angles were compared between sitting and standing position, there were slight differences. In sitting position, there was no difference in spinal segment motion angle between LBP group and painless group while hip joint motion angle and sacral inclination angle of LBP group was lower than those of painless group (p<.05). In standing position, lumbar segment motion angle was significantly lower in LBP group than that of painless group. Transversus abdominis strengthening exercise influenced thoracic segment motion angle more significantly than lumbar segment motion angle.

이 연구는 2013년 3월부터 6월까지 3개월간 연세대학교 치위생학과 특성화 선택과정 실습기관 현장실무자 12명을 대상으로 실습학생에게 바라는 역량과 실습체계에 대해 심층 면접한 결과로 내용분석을 하였다. 현장실무자들이 치위생학을 전공하는 학생에게 바라는 역량을 종합해보면, 현장실무 수행과정에서 ‘의욕적 태도와 활발함., ‘우수한 발표능력과 결과물. 그리고 ‘창의력과 리더십., ‘영어 등의 외국어 능력.을 발휘할 때 좋은 역량을 갖춘 학생으로 평가하고 있었다. 그에 반해, ‘현장실무에 대한 준비.와 ‘직업에 대한 헌신과 소명.이 부족해 보일 경우는 그 학생의 역량을 낮게 평가하게 된다는 의견으로 수렴되었다. 더 나은 특성화 선택과정 실습체계 마련을 위해서는 ‘학교와 현장이 지속적으로 협력할 수 있는 프로젝트., ‘현장실무를 위한 기관 간의 원활한 행정교류.와 ‘학생들이 수행하길 원하는 구체적인 활동사항 리스트.를 구축하고, ‘실습과 관련된 제반 사항에 대한 과정평가.가 필요하다는 의견으로 모아졌다. 이 연구를 통해 특성화 선택과정 실습 현장실무자들이 학생들의 역량에 대해 긍정적으로 인식하고 있었고, 기대하는 바도 큰 것을 알 수 있었다. 따라서 학교 밖 현장교육을 보다 체계적이고 지속적으로 활성화할 필요가 있다. 특성화 선택과정 실습은 학생에게는 진로모색을 구체화할 수 있는 좋은 기회를 제공한다. 그리고 현장실무자에게는 학생의 역량을 미리 엿보는 계기가 되고 있음을 알 수 있었다. 따라서 특성화 선택과정 실습이 현장실무자에게 향후 치과위생사 인력선발 과정에 긍정적이고 수월하게 영향을 미칠 수 있을 것으로 기대한다. The aim of this study was to take the field manager`s opinion about the dental hygiene student`s competency. Study design was cross sectional contents analysis with the in-depth interviews. Twelve subjects were randomly selected in half an hour interview. They were signed there`s own autograph on the informed consents. The contents of the qualitative interviews were divided into two parts: student`s competency required for the field practice and the system of the field practice. The first part consisted of the attitude of the field`s practice, how well has accomplished the job, and demanded requirements for the better performance. And the other part was made up of duration of practice, the number of students per institution and other opinion. The results showed that most of them have positive conception about student`s competency. They mentioned that many students have ``enthusiastic behavior and attitude in task performance`` and ``progressive attitude and mind in duty``. While ``lack of interest in practice and sociality``, ``the arrogant demeanor in the fields``, and ``passive behavior and attitude in the interpersonal relationship`` should be avoided for excellent competency. It is required for dental hygiene students to write daily practice record and clarify their reasons to choose the institution for better performance. In addition, it should be considered to make concrete evaluation items and students and field managers should have mutual responsibility.

The ranula is a form of mucocele which specifically occurs in the floor of the mouth. The ranula is classfied into simple ranula and plunging ranula according to the mechanism of development such as the salivary duct obstruction or the extravasation. Clinically this lesion develops as a slowly enlarging painless, fluctuant mass on one side of the floor of the mouth and the mucosa may have a translucent bluish color. An 8-month-old male infant visited our hospital with the chief complaint of the left submandibular swelling and the mass on the floor of the mouth. We tentatively diagnosed a simple ranula. The marsupialization was performed but the sign and the symptom did not subside, so we took the MRI. By the MRI we diagnosed a plunging ranula and excised the sublingual gland via the intraoral approach. The correct diagnosis is essential for the most effective treatment, which is the excision of the sublingual gland.

Background/Aims: Helicobacter pylori infection is presumably associated with iron deficiency and iron deficiency anemia (IDA). This study aimed to evaluate the relationship between H. pylori infection and the decline in iron stores in non-elderly adults during their health check-ups. Methods: We identified a total of 1,069 subjects who were tested for iron, ferritin, and total iron-binding capacity during their health check-ups, from January 2016 to May 2017. Of these, subjects who underwent endoscopy via rapid urease test and those aged 65 years or below were finally enrolled. Results: Overall, 281 subjects were enrolled, and 187 patients (66.5%) tested positive for H. pylori. The mean age was 36.1 years (range, 22 to 65), and 176 subjects (62.6%) were male. The mean levels of hemoglobin (14.1 ± 1.7 g/dL vs. 14.6 ± 1.4 g/dL, p = 0.019) and ferritin (121.7 ± 106.9 ng/mL vs. 151.8 ± 107.8 ng/mL, p = 0.027) in the H. pylori-positive group were significantly lower than those in the H. pylori-negative group. Iron deficiency (ferritin < 30 ng/mL) was more common in patients with H. pylori infection (p = 0.002). There was no significant difference in anemia (hemoglobin < 13 g/dL in men, < 12 g/dL in women) or IDA (anemia, ferritin < 10 ng/mL, and transferrin saturation < 16%) with H. pylori. Logistic regression analysis demonstrated that female sex (odds ratio, 197.559; 95% confidence interval, 26.461 to 1,475.015) and H. pylori infection (odds ratio, 3.033; 95% confidence interval, 1.216 to 7.567) were factors associated with iron deficiency. Conclusions: H. pylori infection is associated with iron deficiency, suggesting a decline in iron stores among infected non-elderly adults.

Objectives: This study was designed to examine the effects of extracts of Ojeoksangamibang(Wujisanjiaweifang) on the lipid lowering, anti-oxidation and concentration of proinflammatory cytokines and was investigated on hyperlipidemic rats. Methods: Male rats weighing 182.39±4.71 g were fed high fat diet for 8 weeks and 36 rats(above 400 g) were divided into 4 groups. Each of 9 rats was divided into a control group and experimental groups. We fed a control group of rats a basal diet and administered normal saline(100 mg/kg, 1 time/1 day) for 4 weeks. And we fed each experimental group of rats basal diet and administered an extract of Ojeoksangamibang(Wujisanjiaweifang) extracts(100 mg/kg, 200 mg/kg, 300 mg/kg, 1 time/1 day) for 4 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. We measured lipid of plasma and liver, concentration of proinflammatory cytokines, anti-oxidative activity and TNF-α, Apo-B, Apo-E and leptin gene expression. Results: 1. Concentration of plasma free fatty acid(FFA) showed no significant difference in all the treatment groups. Concentration of plasma triglyceride(TG) showed a significant decrement in the 300 mg/kg in Ojeoksangamibang(Wujisanjiaweifang) groups than that of control group. 2. Concentration of plasma total cholesterol showed a significant decrement in the 200 and 300 mg/kg in Ojeoksangamibang(Wujisanjiaweifang) groups than that of control group. Concentration of plasma low density lipoprotein(LDL)-cholesterol showed a significant decrement in the 300 mg/kg in Ojeoksangamibang(Wujisanjiaweifang) groups than that of control group. Concentration of plasma high density lipoprotein(HDL)-cholesterol showed a significant increment in the 300 mg/kg in Ojeoksangamibang(Wujisanjiaweifang) groups. 3. Concentration of liver total cholesterol showed a tendence to decrease in Ojeoksangamibang(Wujisanjiaweifang) groups. Concentration of liver TG showed a significant decrement in all Ojeoksangamibang groups than that of control group. 4. Concentration of plasma and liver thiobarbituric acid reactive substance(TBARS) showed a tendence to decrease in Ojeoksangamibang(Wujisanjiaweifang) groups. 5. The values of glutathione peroxidase(GSH-Px), superoxide dismutase(SOD) and catalase(CAT) activity showed a significant increment in all Ojeoksangamibang (Wujisanjiaweifang) groups than that of control group. 6. The values of plasma aspartate aminotransferase(AST) and alanine aminotransferase(ALT) activity showed no significant difference in all treatment groups. 7. Concentration of plasma interleukin(IL)-1β showed no significant difference in all the treatment groups. Concentration of plasma IL-6 showed a significant decrement in the 300 mg/kg in Ojeoksangamibang(Wujisanjiaweifang) groups than that of control group. Concentration of plasma tumor necrosis factor-α (TNF-α) a significant decrement in the 200 and 300 mg/kg in Ojeoksangamibang(Wujisanjiaweifang) groups than that of control group. However the concentration of plasma IL-10 in the 300 mg/kg Ojeoksangamibang(Wujisanjiaweifang) groups showed a significant increment than that of control group. 8. Concentration of liver IL-1β, TNF-α, IL-6 and IL-10 showed no significant difference in among treatment groups. 9. In the analysis of reverse transcription-polymerase chain reaction(RT-PCR), gene expression of TNF-α, Apo-B and Apo-E in the Ojeoksangamibang (Wujisanjiaweifang) groups showed a lower expression than that of control group. However the gene expression of leptin showed no difference in the treatment groups. 10. The ratio of TNF-α, Apo-B and Apo-E per β-actin expression in the Ojeoksangamibang(Wujisanjiaweifang) groups showed a significant decrement than that of control group. However The ratio of leptin expression per β-actin expression showed no significant difference among all the treatment groups. Conclusions: According to above results, in lowering lipid effect, anti-oxidation and control of pro-inflammatory cytokines production, Ojeoksangamibang(Wujisanjiaweifang) gives positive effect.

LT, Other : O-072 ; Host injury in acute viral hepatitis is attributed to cytotoxic T lymphocytes not specific to the infecting virus

( Dong Yeop Chang ),( Hyun Woong Lee ),( Won Seok Kang ),( Young Jun Koh ),( Jino Lee ),( So Youn Shin ),( Soo Seong You ),( Yoon Seok Choi ),( Ji Hye Kim ),( In Soo Oh ),( Dong Ho Lee ),( Kyung Suk S 대한간학회 2012 춘·추계 학술대회 (KASL) Vol.2012 No.-

Background/Aims: During viral infection, tissue damage is caused not only by direct cytopathic effects of virus but also by host immune responses. We investigated activation status and functions of CD8+ T cells and the mechanism of CD8+ T cell-mediated host injury in acute hepatitis A (AHA), which is caused by hepatitis A virus (HAV) infection and manifested by severe liver injury in adults. Methods: The study population was AHA-diagnosed 56 patients, hospitalized in Chung-Ang University Hospital. All patients were seropositive for anti-HAV IgM and had clinical and laboratory features of acute hepatitis. The whole blood and serum were obtained, and peripheral blood mononuclear cells were isolated by Ficoll density-gradient centrifugation and cryopreserved. Direct ex vivo IFN-γ ELISpot assay of peripheral blood lymphocytes was performed by stimulating them with overlapping peptides for HAV VP2 and 3C proteins in order to assess comprehensively HAV-specific IFN-γ response. Results: Total IFN-γ response against VP2 and 3C did not show positive correlation to serum ALT level, corroborating that the liver injury of AHA is not associated with HAV-specific T cell response. Activation of unrelated virus-specific CD8+ T cells significantly correlated with the percentage of CD38+HLA-DR+ cells in total CD8+ T cells, which was a correlate of the liver injury. In a prospective analysis, the percentage of CD38+ HLA-DR+ cells in total CD8+ T cells or that in unrelated virusspecific CD8+ T cells decreased along with the decrease in serum ALT level at the time of discharge, but that in HAVspecific CD8+ T cell population did not. Conclusions: We demonstrate that unrelated virus-specific CD8+ T cells, which are not specific to HAV, are activated and proliferating in AHA, the severity of liver injury correlates with the activation of non-HAV-specific CD8+ T cells, not to that of HAV-specific T cells.
