혈중 지질농도는 식이단백질 종류보다는 연령의 영향을 많이 받아, young군보다 old군의 총 콜레스테롤, TG, HDL-콜레스테롤, LDL+VLDL-콜레스테롤 및 AI 모두 높았다. 한편 콩 단백질군에서 HDL-콜레스테롤 수준이 증가하고, LDL+VLDL-콜레스테롤와 AI는 감소하여, 심혈관질환에 대한 콩 단백질의 유익한 효과를 확인할 수 있었다. 식이단백질에 의해 유의한 영향을 받은 혈장 인지질의 지방산조성중 22:0, 18:1ω9, ∑MUFA 조성은 카제인군에서 콩 단백질군 보다 높았으며, 반대로 ∑SFA 조성은 카제인군에서 낮았다. 연령에 의해 혈장 인지질 지방산 조성에 있어 유의한 차이를 보인 지방산 중 22:0, 18:1ω9, 22:1, 18:3ω3 및 22:4ω6는 young군에서 높은 반면에, 22:6ω3, ∑ω3, 18:2ω6, 20:4ω6, ∑ω6 및 ∑PUFA의 조성비율은 old군에서 높게 나타났다. 이와 같이 식이 단백질의 종류보다 연령의 영향력이 더 많이 나타난 것은 혈중 콜레스테롤 수준이 식이 단백질보다는 연령의 영향을 더 크게 받았기 때문으로 생각된다. 혈장 인지질 지방산의 대사지표 중 Δ7-desaturation index(16:0⇒16:1ω7)와 Δ9-desaturation index(18:0⇒18:1ω9)가 식이 단백질의 영향을 받아 카제인군에 비해 콩 단백질군에서 유의하게 낮았다. Δ7- 및 Δ9-desaturation index만이 식이 단백질의 영향을 받은 것은 식이 단백질보다 desaturase 활성에 더 큰 영향력을 미치는 콜레스테롤이 식이에 첨가되었기 때문이라 생각된다. Δ-4 desaturation index (22:4ω6⇒22:5ω6)는 young군에 비해 old군에서 높았으며, elongation index(20:4 ω6⇒22:4ω6)는 old군에서 낮았다. 대부분의 elongation과 desaturation 단계는 연령에 따라 유의한 차이를 보이지 못하였으나, ω3계 지방산의 전체적인 elongation-desaturation 단계를 나타내는 ∑products-fatty acid(ω3)/α-LNA(ω3) 비율이 old군에서 young군보다 유의하게 높아, 연령에 따른 PUFA 대사의 변화가 관찰되었다. 이상에서와 같이, 콩 단백질의 섭취로 흰쥐 혈장 인지질의 ∑MUFA 조성은 낮고 ∑SFA 조성은 높아 다른 지질 강화성분의 섭취와 유사한 결과를 나타내었다. 혈중 콜레스테롤 수준이 높은 old군에서 체내 막조직의 유동성을 유지하기 위해 PUFA의 합성 특히 ω3계 지방산의 elongation-desaturation이 증가하여 총 PUFA 조성이 young군보다 높았다. 연구결과로 이소플라본을 포함한 콩 단백질의 혈중 지질저하 기전에 대해 체계적인 설명은할 수 없지만, 콩 단백질이 혈장 지방산의 조성을 변화시킴으로써 간접적으로 심혈관계 질환에 대해 유익한 효과를 미침을 알 수 있었다. 한편, 이러한 혈관의 건강과 관련된 콩의 유익한 효과는 이소플라본과 같은 콩의 특정 성분의 단독효과라기보다는 콩 단백질과의 복합효과에 의한 것이라는 주장은 매우 설득력 있다고 생각된다. Effects of soy protein concentrate (SPC) containing isoflavone and casein diets on plasma phospholipid (PLs)-fatty acid patterns were investigated in 7- & 40- wk old female rats. Diets containing 16% SPC (soy/young: SY, soy/old: SO) and casein (casein/young: CY, casein/ old: CO) supplemented with 0.5% cholesterol were fed for 4 wks. Fatty acid compositions of plasma PLs were determined by TLC and GLC. Compared to the dietary protein effects, age effects on serum lipids were more profound. The levels of total cholesterol (Chol.), triglyceride, HDL-Chol., (LDL+VLDL)-Chol. and atherogenic index (AI) were higher in older groups (OC & OS) than younger groups (YC & YS). Soy groups had higher HDL-Chol. level and lower (LDL+VLDL)-Chol. and AI, compared with casein groups. The compositions of C22:0, C18:1ω9 and sum of MUFA in plasma PLs were significantly higher in casein group (CY & CO) than soy group (SY & SO), but those of sum of SFA were higher in soy group. The compositions of C22:0, C18:1ω9, C22:1, C18:3ω3 and C22:4ω6 were higher and those of C22:6ω3, sum ofω3, C18:2ω6 C20:4ω6, sum ofω6 and sum of PUFA were lower in plasma PLs of younger rats. The average P/S and ω3/ω6 ratio in older group was higher. The Δ-7 desaturation index (16:0⇒16:1ω7) and Δ-9 desaturation index (18:0⇒18 : 1ω9) were lower in soy group than casein group, while Δ-6 and Δ-5 desaturation index were not affected by dietary protein. The Δ-4 desaturation index (22:4ω6⇒22:5ω6) were higher and, elongation index (20:4ω6⇒22:4ω6) were lower in older group. The ratio of the products of ω3 fatty acid series/precursor of ω3 fatty acid series (C18:3) was significantly higher in older group, which in- dicated that age affected the plasma PUFA metabolism. On the other hand, older rats had higher serum cholesterol level compared with younger rats. Taken together, these changes in fatty acid composition might cause minimal changes in the membrane fluidity induced by the increase serum cholesterol level.

The Association Between Long Working Hours and Infertility

Ahn Joonho,Lee Sang Ha,Park Min Young,Oh Soo Hyun,Lee Wanhyung 한국산업안전보건공단 산업안전보건연구원 2021 Safety and health at work Vol.12 No.4

Background: This study aimed to investigate whether working long hours was related to infertility among female Korean workers, while taking age into consideration. Methods: We used data from the 2018 National Survey on Fertility and Family Health and Welfare in Korea that is a cross-sectional, nationally representative, and population-based survey. Infertility was defined as women who were not pregnant after regular unprotected intercourse for a year. Working long hours was classified as ≥52 hours, and subgroups as per age were classified on the basis of being younger or older than 40 years of age. Differences in infertility risk between the long working hour group and none were estimated in crude and fully adjusted logistic regression models with age-group stratification. Results: Of 5,909 Korean female workers, the crude and adjusted odds ratios (95% confidence intervals) of infertility for working long hours were 1.295 (0.948-1.737) and 1.303 (0.921-1.809), respectively. In the subgroup of patients below 40 years of age, the crude and adjusted odds ratios (95% confidence interval) were 1.957 (1.216-3.039) and 1.921 (1.144-3.120), whereas those aged 40 years or older had 0.994 (0.647-1.471) and 0.939 (0.560-1.501), respectively. The weighted prevalence of infertility increased as weekly working hours increased only for the younger than 40-year subgroup. Conclusions: Infertility is associated with working long hours, especially in young-aged workers. Thus, the working schedule must be structured to better suit young female workers.

조혈모세포이식 환자에서의 기계 환기의 위험 인자 : Assessment of Risk Factors

안중경,이홍기,황정혜,박세훈,이효락,송서영,이순일,박준오,김기현,김원석,정철원,임영혁,강원기,박근칠 대한조혈모세포이식학회 2002 대한조혈모세포이식학회지 Vol.7 No.1

연구배경: 조혈모세포이식을 시행한 환자에서 집중 치료 시 예후가 매우 나쁜 것으로 알려져 있고, 기계 환기는 강력한 사망 예측 인자로서 보고되고 있다. 그러나 현재까지 이식 환자에서 기계 환기의 위험 인자를 밝힌 연구는 매우 드물다. 따라서 기계 환기를 시행한 조혈모세포이식 환자의 임상적 특징을 살펴보고 기계 환기에 대한 위험 인자를 알아보고자 하였다. 방법: 삼성서울병원에서 조혈모세포이식을 시행한 환자 중 기계 환기를 시행한 23명과 기계 환기를 시행하지 않은 142명을 대상으로 후향적 연구를 시행하였다. 기계 환기에 대한 위험 인자의 여부에 관해서는 chi-square 또는 Fisher's exact 검정을 시행하였으며 기계 환기에 대한 각 위험 인자의 영향에 관해서는 다중로지스틱 회귀분석을 시행하였다. 결과: 기계 환기를 시행한 23명의 환자 중 30일째 생존자는 1명이었고 6개월째 생존율은 0%였다. 생존자와 사망자 모두에서 다기관 기능부전이 관찰되었으며, APACHE II 점수와 SAPS II 점수에 의한 예측 사망률은 각각 56%, 59%였다. 조혈모세포이식 후 기계 환기의 위험 인자로는 선행 질환이 혈액질환, 부분불일치 동종이식, 간정맥폐색성질환, 이식 전 질병 상태가 재발하였거나 약물에 반응하지 않는 경우였다. 다중로지스틱 회귀분석 결과 기계 환기의 위험 인자로 통계적으로 유의한 차이를 나타낸 것은 단지 부분불일치 동종이식을 시행한 경우였다. 결론: 현재까지 조혈모세포이식 환자에서 집중 치료의 역할에 대해서는 확실히 정립되어 있지는 않으며, 이식 환자에서 기계 환기는 강력한 사망 예측 인자이다. 따라서, 조혈모세포이식을 시행한 환자에서 기계 환기의 위험 인자와 불량한 예후 인자를 고려하여 기계 환기 여부에 대한 신중한 결정을 내려야 한다. Background: Respiratory failure requiring mechanical ventilation is a frequent, critical complication of hematopoietic stem cell transplantation (HSCT). Patients who require mechanical ventilatory support after HSCT generally have a very poor prognosis. Mechanical ventilation in HSCT recipients is a strong predictive factor of mortality. The objectives of this study are to describe clinical characteristics of HSCT recipients undergoing mechanical ventilation and to identify the risk factors for mechanical ventilatory support after HSCT. Methods: We performed a retrospective chart review of all patients >15 yrs old who received HSCT at Samsung Medical Center and subsequently required mechanical ventilatory support between 1996 and 2001. Results: Thirty-day mortality rate in HSCT recipients undergoing mechanical ventilation was 95.6%. The mean predictive mortality rates of APAHCE II score and SAPS II score were 56% and 59%, respectively. Reasons for mechanical ventila-tion were sepsis (47.8%) followed by fungal infection (13%) and diffuse alveolar hemorrhage (8.7%). Univariate analysis identified relapsed or refractory diseases at HSCT, hematologic disease, hepatic venoocclusive disease and allogeneic or HLA-mismatched transplant as significant risk factors for mechanical ventilation. On multivariate logistic regression analysis, only allogeneic mismatched transplant remained significant. Conclusion: Overall outcome of HSCT recipients undergoing mechanical ventilation is very poor. Therefore, the risk factors and the poor prognostic factors for mechanical ventilation should be taken into account in making further treatment decision for HSCT recipients requiring mechanical ventilation.

食用油脂는 健康維持에 必須的인 營養素이다. 그러나 食用油脂는 脂肪을 構成하는 脂肪酸의 種類와 攝取하는 量에 따라 健康을 保衛하는 必須的인 食品의 成分이 되기도 하고 有害한 影響을 끼칠 수도 있어서 脂質代謝와 關連된 疾病 뿐만아니라 老化를 促進하고, 乳房癌, 大腸癌等의 癌發生과도 關連된 것으로 밝혀져 있다. 本 硏究는 우리生活環境에서 食用으로 接할 수 있는 10種의 油脂에 對한 免疫生物學的인 活性에서 究明한 結果 對照群인 참기름食餌群에 比해 올리브유食用群은 全般的으로 體液性 및 細胞性免疫을 有意性있게 增加시켰으나, 大食細胞의 活性과 末梢循環白血球數는 有意性없는 減少를 보였고, 動物性 油脂인 牛脂食餌群과 植物性 油脂인 옥수수기름食餌群, 들기름食餌群, 米糠油食餌群, 大豆油食餌群, 菜種油食餌群 및 고추씨기름食餌群에서는 全般的으로 體液性 및 細胞性免疫, 大食細胞의 活性 및 末梢循環白血球數를 有意性있게 減少시켰다. This study was performed to investigate the effects of edible oils and fats on the immunobiological responses in ICR male mice. Ten groups of experimental diets, such as sesame oil diet, beef tallow diet, lard oil diet, olive oil diet, corn oil diet, perilla oil diet, rice polishing oil diet, soybeen oil diet, rape seed oil diet, and red pepper seed oil diet were fed adlibitum to the ICR male mice for 27 days. The results of this study were summarized as followings. 1. Both humoral and cellular immune responses, phagocyte activity, and number of leukocytes in sesame oil group were increased. However, the increasing rate of body weight and the weight retios of spleen and thymus to body were generally decreased. 2. Hemagglutination titer(HA) and rosette forming cell(RFC) of the beef tallow group and the lard group were significantly lower than the sesame oil group(P<0.01), but the lard group significantly increased Arthus reaction and delayed type hypersensitivity(DTH)(P<0.01). 3. Arthus reaction, DTH, and RFC of the olive oil group were significantly higher than the sesame oil group(P<0.01). 4. DTH of the corn oil group was significantly higher than the sesame oil group(P<0.01) whereas phagochyte activity was significantly lower(P<0.01). But no statistically significant differences were found between the two groups in the humoral immune response. 5. HA, PFC, DTH, RFC, phagocyte activity, and number of leukocytes of the perilla oil group and the rice polishing oil group were significantly lower than the sesame oil group(P<0.01). 6. Both humoral and cellular immune responses, phagocyte activity, and number of leukocytes of the soybeen oil group, the rape seed oil group, and the red pepper oil group were significantly lower than the sesame oil group(P<0.01).

Reconstruction of Rabbit Corneal Epithelium on Lyophilized Amniotic Membrane Using the Tilting Dynamic Culture Method

Ahn, Jae-Il,Lee, Doo-Hoon,Ryu, Yang-Hwan,Jang, In-Keun,Yoon, Mun-Young,Shin, Youn Ho,Seo, Young-Kwon,Yoon, Hee-Hoon,Kim, Jae-Chan,Song, Kye-Yong,Yang, Eun-Kyung,Kim, Ki-Ho,Park, Jung-Keug Blackwell Publishing Inc 2007 Artificial Organs Vol.31 No.9

<P>Abstract: </P><P>Rabbit corneal epithelium was reconstructed using tilting dynamic culture with a self-manufactured, amniotic membrane (AM) supporter and a lyophilized amniotic membrane (LAM). Rabbit corneal epithelial (RCE) cells were cultured and cryopreserved after isolation from the limbus. The second- and third-passage RCE cells were plated onto the epithelial side of the LAM of Ahn's AM supporter. Two days later, the air–liquid interface culture was maintained with third-passage RCE cells for 6 days and second-passage corneal epithelial cells for 9 days. The average viability of thawed RCE cells, assessed using trypan blue dye exclusion, was 77.42%. The reconstructed corneal epithelium was characterized by histological (hematoxylin and eosin) and immunohistochemical staining (proliferating cell nuclear antigen) for light microscopy, and by reverse transcriptase-polymerase chain reaction, glucose assay, and transmission electron microscopy. The basal layer of the reconstructed corneal epithelium was well formed, and the epithelium was tightly constructed due to the increase in cell proliferation and differentiation caused by the tilting dynamic culture, as opposed to static culture. Tilting dynamic culture was useful for the reconstruction of the epithelium using easily damaged epithelial cells and resulted in more stratum cell layers. Moreover, cytokeratin (CK3) mRNA expression in tilting dynamic cultured third-passage RCE cells seeded onto AM was greater than in static cultured third-passage RCE cells. The morphology of the reconstructed corneal epithelium on LAM by tilting dynamic culture for 9 days resembled that of the skin epidermis. This was thought to be because the tilting dynamic culture not only accelerated the proliferation and differentiation of cells by physical or mechanical stimulation, but also ensured that the supply of medium was delivered to the basal cells more efficiently. Thus, the reconstruction of the corneal epithelium using LAM and tilting dynamic culture was considered to be a good in vitro model for autologous or allogeneic transplantation of corneal epithelium and skin epidermis in patients with damaged epithelia. </P>

학교보건교육에서의 매체활용실태 및 영향요인 분석

박은옥,안지영,정혜선,김영임,박정영 韓國學校保健學會 1999 韓國學校保健學會誌 Vol.12 No.2

The objectives of this study are to explain the use of media materials in school health education with other related factors in elementary, middle, and high schools in Korea. The data were collected by questionnaires from June to September in 1988. The number of subjects were 294 school nurses. The PC-SAS program was used for statistical analysis such as percent distribution, chi-squared test, spearman correlation test, and logistic regression. The use of media materials in health education has become extremely common. Unfortunately, much of the early materials were of poor production quality, reflected low levels of interest, and generally did little to enhance health education programming. A recent trend in media materials is a move away from the fact filled production to a more affective, process-oriented approach. There is an obvious need for health educators to use high-quality, polished productions in order to counteract the same levels of quality used by commercial agencies that often promote "unhealthy" lifestyles. Health educators need to be aware of the advantages and disadvantages of the various forms of media. Selecting media materials should be based on more than cost, availability, and personal preference. Selection should be based on the goal of achieving behavioral objectives formulated before the review process begins. The decision to use no media materials rather than something of dubious quality will usually be the right decision. Poor-quality, outdated, or boring materials will usually have a detrimental effect on the presentation. Media materials should be viewed as vehicles to enhance learning, not products that will stand in isolation. Process of materials is an essential part of the educational process. The major results were as follows:1. The elementary schools used the materials more frequently. But the production rate of media materials was not enough. The budget was too small for a wide use of media materials in school health education. These findings suggest that all schools have to increase the budget of health education programs. 2. Computers offer an incredibly diverse set of possibilities for use in health education, ranging from complicated statistical analysis to elementary-school-level health education games. But the use rate of this material was not high. The development of related software is essential. 3. In this study, the most effective materials were films in elementary school and videotapes in middle and high school. Film tends to be a more emotive medium than videotape. The difficulties of media selection involved the small amount of extant educational materials. Media selection is a multifaceted process and should be based on a combination of sound principles. 4. The review of material use following student levels showed that the more the contents were various, the more the use rate was high. 5. Health education videotapes and overhead projectors proved the most plentiful and widest media tools. The information depicted was more likely to be current. As a means to display both text and graphic information, this instructional medium has proven to be both effective and enduring. 6. An analysis of how effective the quality of school nurse and school use of media materials shows a result that is not complete)p=0.1113). But, the budget of health education is a significant variable. The increase of the budget therefore is essential to effective use of media materials. From these results it is recommended that various media materials be developed and be wide used.

Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

황상희,박인숙,남기영,김종배,조용원,서영성,안병훈,박신구,박효상 대한치과교정학회 2008 대한치과교정학회지 Vol.38 No.3

본 연구는 비만도에 따른 한국인 남성 폐쇄성수면무호흡 환자의 측모 두부 방사선계측학적 특성을 파악하기 위하여 시행되었다. 이를 위하여 계명대학교 의과대학 동산의료원 수면클리닉에 수면장애를 주소로 내원하여 수면다원검사 후 치과에서 측모 두부방사선계측사진 촬영을 한 87명의 성인 환자들을 체질량지수(BMI)와 수면무호흡지수(AHI)에 따라 비비만 단순코골이군(Non-obese, simple snorers), 비만 단순코골이군(Obese, simple snorers), 비비만 수면 무호흡군(Non-obese, OSA patients), 비만 수면무호흡군(Obese, OSA patients)의 4군으로 나누어 비교하였다. 그결과, 4군 중 비만 수면무호흡군의 수면무호흡지수가 가장 컸으며, 비만 수면무호흡군보다 비비만 수면무호흡군의 하악각이 더 크고 혀 길이는 더 작았다. 또한, 비비만 수면무호흡군보다 비만수면무호흡군의 설골이 더 전하방에 위치하였고, 수면무호흡지수에 영향을 미치는 기여 인자는 비만 수면무호흡군에서는 혀 길이, 비비만 수면무호흡군에서는 설골의 후방위치였다. 이처럼 비만 수면무호흡 환자와 비비만 수면무호흡 환자의 측모 두부방사선계측학적 특성과 기여 인자가 다르게 나타나므로, 치료방법도 따라서 다르게 선택해야 할 것이다. 비만 수면무호흡 환자들에게는 먼저 체중감량이 권고되어야 할 것이고, 비비만 수면무호흡 환자들은 폐쇄부위에 따라 구강 내 장치나 Nasal CPAP (continuous positive airway pressure), UPPP (uvulopalatopharyngoplasty) 등이 추천될 수 있을 것이다. Objective: The purpose of this study was to compare the cephalometric measurements of obese and non-obese Korean male patients with obstructive sleep apnea syndrome (OSA). Methods: Eighty-seven adults who had visited the Sleep Disorder Clinic Center in Keimyung University, Daegu, Korea were examined and evaluated with polysomnography (PSG) and lateral cephalogram. They were divided into 4 groups (non-obese simple snorers, obese simple snorers, non-obese OSA patients, obese OSA patients) according to AHI (Apnea-Hypopnea Index) and BMI (Body Mass Index). Results: The obese OSA group had the highest AHI among the 4 groups. The non-obese OSA group had a significantly steeper mandibular angle and shorter tongue length than the obese OSA group. The hyoid bone of the obese OSA group was positioned anterior and inferior as compared with the non-obese OSA group. Multiple regression analysis showed that tongue length in the obese OSA group and retroposition of hyoid bone in the non-obese OSA group were significant determinants for the severity of AHI. Conclusions: From a cephalometric point of view, the obese and non-obese pateints with OSA may be characterized by different pathogeneses. Therefore, they have to be managed by individualized treatment. For the obese OSA patients, weight control must be advised as a first choice and for the non-obese OSA patients, oral appliance, nasal CPAP, UPPP and others could be chosen according to the obstructive sites.
