This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

Objectives Mindfulness-base cognitive therapy (MBCT) has been used to treat patients with depression to prevent relapse. The purpose of this study was to examine the effectiveness of Mindfulness-Base Cognitive Therapy for patients who suffer with generalized anxiety disorder or panic disorder for 1 year. Methods 19 patients with generalized anxiety disorder or panic disorder were assigned to receive MBCT for a period of 8 weeks. The Hamiltion Anxiety Rating Scale (HAM-A), the Hamilton Depression Rating Scale (HAM-D), the Beck Anxiety Inventory (BAI) and the Beck Depression inventory (BDI) were used at 0 weeks, 8 weeks and 1 year to assess the results. Results MBCT demonstrated significantly decreases on all the anxiety scale scores (HAM-A, p=0.00 ; BAI, p=0.00) and depressive scale scores (HAM-D, p=0.99 ; BDI, p=0.00). The patients who received 8-week of MBCT showed a higher remission rate (15/19, 78%) during the 1-year follow-up period. Conclusion MBCT may be effective at relieving the anxiety and depressive symptoms of patients who suffer with generalzed anxiety disorder or panic disorder for 1 year. However, further well-designed controlled trials are needed to assess the value of MBCT.

윤의성,천병철,박미숙,김순덕,염용태 고려대학교 의과대학 1997 고려대 의대 잡지 Vol.34 No.3

We reviewed the health screening record(1996) of a university to compare cardiovascular risk factors and major health behavior of teaching staffs with those of other staffs. The reviewed cardiovascular risk factors were body mass index (BMI), blood pressure (BP), total cholesterol (TCH) and fasting blood sugar (FBS). Smoking, drinking, exercise and diet habits were cheked as major risk factors. We defined the obesty (BMI>25), hypertension (systolic BP 140 or diastolic BP 90 mmHg), hypercholesterolemia (TCH 230mg/dl), and hyperglucosemia (FBS 110mg/dl) , drinking group (alcohol intake 3-4 times a week and over 1 bottle of soju a time), smoking group (smoking over 10 cigarettes a day), non-exercising group(do excercise below 3-4 times a week, and below 30 min a times), unbalanced diet group(do favor salty and spicy food or do favor flesh food). The 1,341(81.7%) of 1,640 staffs were screened in 1996, the teaching staffs were 614(69.3% of 886 teaching staffs) and other staffs (mainly clerks and administrators) were 737(97.7% of 754). 41 (6.7%) of teaching staffs were female and 166(22.4%) of the other staffs were. Among the teaching staffs, there were no below age 30 but 11.5% of them were over 60; in case of the other staffs 11.3% and 2.0% were in each age group. We divided the teaching staffs into medical staffs and non-medical staffs and compare the risk factors of each group. The total number of screened medical staffs were 92(36.2%) of 254, and non-medical staffs were 522 (82.6%) of 632. The results were follows; 1) The frequency of hypertension of each group were significantly different (7.2% in teaching staff, 11.8% in other staffs) after adjusting sex, age, smoking, drinking, exercise, and diet habits by multiple logistic regression (p<0.001). Hyperglucosemia were founded 10.5% and 12.4% in each staffs and the difference were significant after adjusting age, sex and health habits(p=0.005). Teaching staffs had more hypercholesterolemic persons than other staffs(24.3%, 16.3% in each staffs, p=0.019). Obesity frequency was not significantly different. 2) The number of drinking group were 114(18.6%), 208(28.3%) in each staffs, and this difference were significantly different (CMH=38.295, p=0.001). The number of smoker were 140(22.8%) and 274(37.2%) (CMH=58.109, p=0.001). The frequency of non-exercising group and the frequency of unbalanced diet group were not significantly different. 3) The frequency of obesity were 39.1% and 30.9% in each medical and non-medical staffs (CMH=4.414, p=0.036), but this difference remains non-significant after adjusting by the health habits. The frequency of hyperglucosemia of medical staffs (17.4%) were significantly higher than non-medical staffs (9.2%) after adjusting age, sex and the health habits (p=0.0005). Other risk factors were not significantly different. 4) Medical staffs had more smoker(29.4%) than non-medical staffs(21.5%) (CMH=6.401, p=0.011) and more non-exercising persons (27.2%) then non-medical staffs(11.1%) (CMH=12.446, p=0.001). Other health behaviors are not significantly different.

유현상,강선녀,정창모,윤미정,허중보,전영찬 대한치과보철학회 2012 대한치과보철학회지 Vol.50 No.1

연구 목적: 임플란트 경부가 잘 설계된 경우 양호한 연조직 반응을 통해 변연골을 보존하는데 도움이 된다. 본 실험에서는 연, 경조직 경계부에 가장 가까이 위치하는 임플란트의 collar design이 변연골 변화와 연조직 반응에 미치는 영향을 동물실험을 통해 알아보고자 하였다. 연구 재료 및 방법: 2마리의 건강한 Beagle dog에 임플란트 collar design만 다른 두 종류의 임플란트(Neobiotech Co. Seoul, Korea)를 식립하였다. Collar에 bevel 을 부여한 군(Bevel 군)과 "S"자 형태를 부여한 군(Bioseal 군)으로 나누어 마리 당 7개, 군당 7개, 총 14개의 임플란트를 무작위로 식립한 후 Healing abutment를 즉시 체결하였다. 디지털 표준구내 방사선사진을 이용해 4주 간격으로 총 12주간 근원심 변연골 변화를 관찰하였고, 12주에 희생하여 조직학적 분석을 통해 협설 변연골 흡수 및 임플란트 주변 연조직 반응을 평가하였다. Mann-Whitney test를 통해 동일한 방사선 사진 촬영 시점에서 근원심 변연골 변화량 및 조직계측치를 군 간 비교하였고, Kruskal-Wallis test를 통해 방사선 사진상 근원심 변연골 변화량이 시간에 따른 차이가 있는지 군 내 분석 한 후 Duncan test를 통해 사후 검증하였다(α=.05). 결과: 방사선학적 분석 결과 각 촬영 시점에서 두 군간 근원심 변연골 변화량의 차이를 보이지 않았다(P>.05). 군 내에서 시간에 따른 근원심 변연골의 흡수량을 분석한 결과 Bevel 군에서는 시간에 따른 차이를 보이지 않았으나 (P>.05), Bioseal 군에서는 시간에 따른 차이를 보였으며, 4주및8주와 비교했을 때 12주에서 변연골의 증가를 보였다(P<.05). 조직학적 분석 결과 협설측 변연골 흡수량에서 두 군간 차이를 보이지 않았으나 (P>.05), Bevel 군에 비해 Bioseal 군에서 더 견고한 결합조직부착을 관찰할 수 있었으며, 생물학적 폭경의 값은 두 집단 간 차이를 보이지 않은 반면에 (P>.05), 접합상피부착은 Bevel 군에서 유의하게 길었고, 결합조직부착은 Bioseal 군에서 더 길게 나타났다(P<.05). 결론: Bevel 군에 비해 Bioseal 군에서 결합조직부착은 길게 형성된 반면에 접합상피부착은 더 짧게 나타났으며, 생물학적 폭경과 초기 변연골 흡수에는 차이가 없음을 알 수 있었다. 연조직 반응의 차이가 실제 기능하중 하에서 변연골 변화에 미치는 영향에 대해서 향후 연구가 필요할 것으로 생각된다. PURPOSE. The purpose of this study was to investigate the effects of implant collar design on marginal bone change and soft tissue response by an animal test. MATERIALS AND METHODS. Two types of Implant (Neobiotech Co. Seoul, Korea) that only differs in collar design were planted on two healthy Beagle dogs. The implants were divided into two groups, the first group with a beveled collar (Bevel Group) and the second group with "S" shaped collar (Bioseal group). Standardized intraoral radiographs were used to investigate the mesio-distal change of the marginal bone. Histological analysis was done to evaluate the bucco-lingual marginal bone resorption and the soft tissue response adjacent to the implant. Mann-Whitney test was done to compare the mesio-distal marginal bone change at equivalent time for taking the radiographs and the tissue measurements between the groups. RESULTS. Radiographic and histological analysis showed that there was no difference in marginal bone change between the two groups (P>.05). Histological analysis showed Bioseal group had more rigid connective tissue attachment than the Bevel group. There was no difference in biological width (P>.05). Bevel group showed significantly longer junctional epithelium attachment and Bioseal group showed longer connective tissue attachment (P<.05). CONCLUSION. For three months there were no differences in marginal bone change between the Bevel group and the Bioseal group. As for the soft tissue adjacent to the implant, Bioseal group showed longer connective tissue attachment while showing shorter junctional epithelium attachment. There were no differences in biologic width.

목적: 최근 국내에서도 골다공증과 관련된 생활양식의 규명에 관한 연구가 이루어지고 있으나, 아직까지 남성 골다공증에 대한 연구가 활발하게 이루어지지 않아 40, 50대 남성근로자를 대상으로 유병률을 파악하고, 골감소증 및 골다공증 관련 위험요인을 확인하고자 하였다. 방법: 원자력발전소에 근무하는 40, 50대 남성 근로자 2,073명을 대상으로 2004년 3월~7월 기간동안 생활습관을 파악하기 위하여 자기기입식 전산입력 방식으로 최종학력, 흡연여부, 음주여부, 신체활동 횟수를 조사하였고, 골밀도검사, 체성분검사(체지방률, 허리-엉덩이둘레비), 신체계측(신장, 체중)을 시행하였고, 골밀도 검사는 Osteosys사의 EXE-3000을 이용하여 종골부위를 측정하였고, 체지방률, 허리-엉덩이 둘레비는 Biospace사의 Inbody 3.0을 이용하여 측정하였다. 통계분석은 골감소증 및 골다공증의 관련요인을 분석하기 위해 다중로지스틱회귀분석을 시행하였다. 결과: 연구대상자의 골감소증 및 골다공증 유병률은 22.8%와 3.0%이었으며, 골감소증 및 골다공증의 관련요인으로는 연령이 증가할수록, 흡연자이거나 과거흡연자일 경우, 체질량지수가 25 kg/m^(2) 미만일 경우, 30분 이상 신체활동 횟수가 주 3회 미만일 경우가 유의한 연관성이 있었다. 결론: 성인 남성 40, 50대의 골감소증 및 골다공증의 유병률이 높은 편이었으며, 골감소증 및 골다공증으로 이환을 예방하기 위하여 금연, 활발한 신체활동을 촉진하여 골밀도를 개선시키는 생활습관으로의 변화를 권고해야 할 것이다. Objective: This study was conducted to investigate the prevalence and risk factors of osteopenia and osteoporosis in 40-59 year-old male workers working at nuclear power plants. Methods: Bone density, body composition, and anthropometry data were analyzed for 2,073 subjects were carried out from March 2004 to July, 2004. Educational level, smoking status, drinking status and frequency of physical activity were investigated by self-reported questionnaires through internet to identify lifestyles related to bone mass density. Bone mass density was measured by EXE-3000 of Osteosys Co. And body fat percentage, and waist-to-hip ratio by inbody 3.0 of Biospace Co. Results: The prevalence of ostepeniaosteopenia and osteoporosis was 22.8% and 3.0%, respectively. According to multinominal multinomial logistic regression analysis, age, smoking status (current smoker and former smoker), low body mass index (< 25kg/m^(2)), and frequency of physical activity were significantly associated with osteopenia and osteoporosis. Conclusions: The prevalence of ostcopenia and osteoporosis wasseemed high for the, when it was inferred from subjects' age compared to the results of previous studies. The This study results suggeststhat it is necessary for 40-59 year-old male workers to stop smoking, and exercise regularly in order to prevent osteopenia and osteoporosis.

유기용제 사용 소규모사업장의 체계적 건강관리 프로그램 개발에 관한 연구1) : 신경행동학적 검사법의 적용 가능성 Application of Neurobehavioral Core Test Battery(NCTB)

한상환,하미나,권호장,윤덕로,조수헌 大韓産業醫學會 1995 대한직업환경의학회지 Vol.7 No.2

It is known that there appear some nonspecific and delicate changes in neuropsychiatric aspect on the workers when they are exposed for a long period to low concentrated organic solvents in the work places. Therefore, it gives rise to the necessity of developing a program for the health supervisor stationed in the work place to supervise these neurobehavioral health affection. In addition to the questionnaire posed to the workers exposed to organic solvents, the study team conducted NCTB(Neurobehavioral Core Test Battery) respectively on an exposed group and a non-exposed group to organic solvents. The study team compared the results and decided whether or not to apply the results to the evaluation program of health affection. The study team divided 132 workers in 6 car repairing factories and 2 textile printing factories into exposed group and non-exposed group, pairing them off into 66 research objects according to their age, sex, and job. Neurobehavioral test was conducted on 6 items, except the POMS test, of NCTB developed by the World Health Organization(WHO). The study team conducted examinations of working environment on the exposed and non-exposed groups of each work place. The analysis of the collected materials for examinations were conducted with GC-MS. The concentration of the mixture in the air, relative to their respective threshold limit values(TLV) was calculated according to the formula of the ACGIH and the Korean threshold limits. The results indicated that for two of eight factories samples the recommended concentration limits for mixtures was exceeded. Of the six tests, the 'digit span forward', 'digit span backward' and 'digit symbol' produced conspicuous statistical differences between the two groups(p<0.1) as a result of compairing the test values by means of paired t-test. The results of respective analysis of the car repairing factories and textile printing factories revealed that the textile printing factories had greater differences between the exposed and the non-exposed than in the car repairing factories. It is presumably because the textile printing workers are continuously exposed to the organic solvents during working hours, whereas the car repairing workers are exposed only when they are doing painting works, The NCTB is assessed very useful in examining the neurobehavioral health affection under the exposure to organic solvents, and, therefore, the study team expects that the NCTB will play an important part in the course of developing a health program for the workers exposed to organic solvents.

B16 melanoma 세포에서 nitric oxide가 멜라닌 생성에 미치는 영향

심상수,조남영,윤미연,이지윤,김창종 중앙대학교 약학연구소 2002 약학 논총 Vol.16 No.-

To investigate the effects of nitric oxide and cGMP on melanin production, we measured the melanin production in B16 melanoma cells stimulated by alpha-melanocyte stimulating hormone (MSH). NO donor, such as, sodium nitroprusside (SNP), SIN-1, SNAP and L-arginine increased melanin production in basal state. SNAP potentiated melanin production by MSH, but other NO donors did not. In the study the potentiating effect of sodium nitroprusside on cAMP-dependent melanin production, sodium nitroprusside did not increase melanin production induced by MSH, forskolin and 8-Br-cAMP. Non-selective cAMP/cGMP phosphodiesterase inhibitor (IBMX) and selective cGMP phosphodiesterase inhibitor (zaprinast) significantly increased MSH-induced melanin production, whereas soluble guanylyl cyclase inhibitor (ODQ) inhibited MSH-induced melanin production. These results suggest the possibility that MSH-stimulated melanin production may be mediated via not only cAMP-dependent pathway but also cGMP-dependent pathway in B16 melanoma cells.

김윤신,이미숙,장원재,임성철,기근홍,전호종,서재홍 조선대학교 1994 The Medical Journal of Chosun University Vol.19 No.2

Pancreas is known for the unfavorable soil to the metastatic carcinoma, and pancreatic metastasis is achieved after systemic dissemination was developed. The primary tumors of metastatic pancreatic carcinoma are breast, lung, Iymphoma, malignant melanoma, leukemia, stomach. and colon. The breast carcinoma is the commonest tumor to metastasize to pancreas and both tumors are related to estrogen receptor for tumor growth. In the present case, tumor cells had small round nucleus and showed indian file infltrating pattern and lack of cohesion, which are seen in infiltrative breast carcinoma. The patient was underwent radical mastectomy due to infiltrative ductal carcinoma three years ago. And also the tumor cells showed nuclear reactivity to immunostaining for estrogen receptor In combination of the histopathologic. immunohistochemical, and her past history, we concluded that breast carcinoma was metastasized to pancreas, and we report a case of metastatic pancreatic carcinoma from breast with review of literatures.
