목적 : TDI는 직업성천식을 일으키는 대표적인 물질로 알려져 있다. 과거 TDI에 노출된 작업자들의 천식 발생률을 5~6%가량 보고하였고, 국내에서도 2-20%에 이르는 유병율을 보고한바 있다. 작업환경이 많이 개선되고, 노출량이 감소된 최근에도 TDI에 의한 직업성천식에 대한 보고가 많이 이루어지고 있어, 이에 대한 적극적인 조사와 진단과정을 통해 유병율을 구하고 질병발생의 변화양상을 파악해 보고자 하였다. 방법 : 인천지역에서 특수건강진단을 수행하는 2개 기관의 TDI 노출 근로자 400여명 중, 사업장의 규모가 50인 이상이며 사업주가 연구진행을 허락한 사업장에서 근무하는 근로자 중 직접적으로 TDI에 노출되는 작업에 종사하는 근로자 170명을 연구대상으로 하였다. 이들에 대해 설문지와 산업의학의사의 면담을 통한 작업관련성 평가를 근거로 정밀대상자를 선정하고 이들에 대해 메타콜린 유발시험, TDI 유발시험 등을 수행하여 직업성천식을 확인하였다. 결과 : 설문조사 결과 11명이 직업과 관련하여 천식증상을 보이는 것으로 나타났고(6.9%), 이중 7명에서 메타콜린 유발검사 양성소견을 보였다. TDI에 의한 특이유발시험 결과 1명에서 양성반응이 나타나, 이 집단에서 TDI에 의한 직업성천식의 유병율은 0.58%였다. 결론 : 과거 국내연구에서 TDI에 의한 직업성천식의 유병율이 2~20%에 이르렀던 데 비해, 본 연구에서는 0.58%로 나타났다. 이는 국외 논문에서도 나타나는 경향으로 작업장 노출량 감소로 점차 발생률이 감소하는 양상을 보이고 있다. 그러나 이미 증상이 나타난 근로자들이 부서를 옮기거나, 직장을 그만둠으로 인해 그 유병율이 과소평가되었을 가능성도 있다고 판단된다. Objecdives: This study was carried out to estimate the prevalence of isocyanate-induced occupational asthma in toluene diisocyanate (TDI) exposed workers. Methods: We examined 170 workers who had been directly exposed to TDI through a medical questionnaire, physical examination, and pulmonary function test. Based on screening examination, workers with suspected occupational asthma were selected for further evaluation such as methacholine and TDI challenge tests. Results: Eleven (6.9%) among 170 workers complained of symptoms of occupational asthma. and 7 among these 11 symptomatic workers showed positive responses to the methacholine challenge test (4.1 %). One spray painter was confirmed as having the TDI induced occupational asthma following a positive response to TDI challenge test. Conclusions: The prevalence of TDI-induced asthma was at 0.58% was lower than that for former studies (2-20%). Improved workplace environment, lower level of TDI exposure compared to the past, and the healthy workers effect may have contributed to this low rate of asthma prevalence in workers with TDI exposure.

Kim, You-Sun,Hong, Goohyeon,Kim, Doh Hyung,Kim, Young Min,Kim, Yoon-Keun,Oh, Yeon-Mok,Jee, Young-Koo Nature Publishing Group UK 2018 Experimental and molecular medicine Vol.50 No.11

<▼1><P>Although the positive effects of recombinant fibroblast growth factor-2 (rFGF-2) in chronic obstructive pulmonary disease (COPD) have been implicated in previous studies, knowledge of its role in COPD remains limited. The mechanism of FGF2 in a COPD mouse model and the therapeutic potential of rFGF-2 were investigated in COPD. The mechanism and protective effects of rFGF-2 were evaluated in cigarette smoke-exposed or elastase-induced COPD animal models. Inflammation was assessed in alveolar cells and lung tissues from mice. FGF-2 was decreased in the lungs of cigarette smoke-exposed mice. Intranasal use of rFGF-2 significantly reduced macrophage-dominant inflammation and alveolar destruction in the lungs. In the elastase-induced emphysema model, rFGF-2 improved regeneration of the lungs. In humans, plasma FGF-2 was decreased significantly in COPD compared with normal subjects (10 subjects, <I>P</I> <I>=</I> 0.037). The safety and efficacy of inhaled rFGF-2 use was examined in COPD patients, along with changes in respiratory symptoms and pulmonary function. A 2-week treatment with inhaled rFGF-2 in COPD (<I>n</I> = 6) resulted in significantly improved respiratory symptoms compared with baseline levels (<I>P</I> <I><</I> 0.05); however, the results were not significant compared with the placebo. The pulmonary function test results of COPD improved numerically compared with those in the placebo, but the difference was not statistically significant. No serious adverse events occurred during treatment with inhaled rFGF-2. The loss of FGF-2 production is an important mechanism in the development of COPD. Inhaling rFGF-2 may be a new therapeutic option for patients with COPD because rFGF-2 decreases inflammation in lungs exposed to cigarette smoke.</P></▼1><▼2><P><B>Lung disease: Inhaling a protein might help</B></P><P>Studies on the role of the protein ‘fibroblast growth factor-2’ (FGF-2) in chronic obstructive pulmonary disease (COPD) suggest that inhaled FGF-2 could help treat the emphysema linked to smoking. Researchers in South Korea led by Young-Koo Jee at Dankook University, Cheonan, and Yeon-Mok Oh at the University of Ulsan, Seoul, studied the role of the reduced FGF-2 levels found in mice with lung inflammation caused by exposure to cigarette smoke. They also uncovered details of a protective effect of inhaled FGF-2, identifying specific cellular and lung structure changes attributed to the administered FGF-2. Reduced FGF-2 levels were also found in patients with COPD. Initial trials revealed some improvement in patients treated with FGF-2, but not at a statistically significant level. Nevertheless, the authors suggest their results justify further investigation of the protein’s therapeutic potential.</P></▼2>

목적 : 아단위 인플루엔자 백신 접종 후 백신의 인플루엔자 예방효과, 인플루엔자 방어 항체형성, 인플루엔자 백신의 안전성을 조사하고자 하였다. 방법 : 총 571명을 대상으로 인플루엔자 백신 접종을 하였고, 이들 접종자에서 인플루엔자 양질환의 이환을 조사하여 인플루엔자 백신의 인플루엔자예방효과를 알아보았고, 백신의 접종 전 및 접종 4주 후 혈청에서 혈구응집억제물(Hemagglutination Inhibition : HAI) 항체 검사를 실시하여 백신의 방어항체생성을 조사하였고, 백신의 안전성을 알아보기 위해 백신접종 후 1주일 이내의 부작용을 조사하였다. 결과 :백신 접종군과 백신 비접종군에서 인플루엔자 양 질환의 이환을 조사한 결과 접종군 28.35%, 비접종군 35.88%으로 나왔으며, p 값이 0.001로 통계적으로 접종군에서 유의하게 낮았고, 인플루엔자 양 질환의 예방 효과는 20.97%를 보였다. 백신의 방어항체 형성의 평가를 위해 유럽의 인플루엔자 백신 허가 기준을 조사하였는데 B/Guangdong/5/94균주의 백신접종 후 항체가 40이상의 비율을 제외한 다른 기준은 모두 만족 시켰다. 부작용은 전체 조사자 521명중 149명(29%)으로 주로 접종 부위의 국소 부작용을 호소했고, 전신 부작용은 2% 내외였으며 특별히 심각한 부작용은 발견되지 않았다. 결론 : 분편 인플루엔자 백신은 인플루엔자양질환의 예방과 방어항체생성에 효과 있으며 안전한 것으로 사료된다. Background : The safety and effectiveness of influenza vaccine are well known in developed country. The influenza vaccination has been recommended as one of the tentative immunization schedule for indicated persons since 1997 in Korea. But there are still no available data about them, even though nearly 5 million doses of influenza vaccine were used in 1997-1998 season. So it is immediately needed to investigate the safety. efficacy and immunogenicity of influenza vaccine among Korean. Methods : We studied the clinical efficacy of influenza vaccine by monitoring Occurrence of influenza-like illness in influenza risk group(vaccination ; 300, non-vaccination; 215) from December in 1997 to March in 1998. We used the split quadrivalent influenza vaccine containing 15 microgram of hemagglutinin of A/Beijing/262/95(HlNl), A/Wuhan/359/95(H3N2), B/Mie/1/93 and B/Guangdong/5/94. Hemagglutination inhibition(HA1) antibody titers were determined before immunization and 1 months after vaccination And we evaluated adverse effect of influenza vaccination at 7 days after vaccination. Results : Influenza vaccination was associated with si@icant reductions in influenza-like spptoms(vaccination group; 28.35%, non-vaccination group, 35.88%, p=0.001). The preventive effect of influenza-like i3lne.s among influenza risk goup was 20.97%. And immunogenicity of influenza A and B exceeded all of the European licensure criteria for immunogenicity except postvaccination proportion of titers 240 of B/Guangdong/5/94 strain. And the adverse effects were mainly local injection site problem and no serious adverse effect was noted. Conclusion : Split influenza vaccine is safe, inmunogenic and eff'tive in influenza risk group in Korea.

Purpose: This study aims to test if the age of pregnant women affects the perception, experience, and attitude towards complementary alternative therapy (CAT), by investigating the perception, experience, and attitude of pregnant women under the age of 35, and above 35 (Advanced Maternal Age). The study will 1) find the general characteristics of pregnant women under and over the age of 35 2) compare the perception, behavior, and experience of pregnant women under and over the age of 35, and 3) find the comparison of the perception, behavior, and experience according to the general characteristics of pregnant women under and over the age of 35. Method: The subjects of this study are composed of 44 women under the age of 35 and 44 women above the age of 35, totaling 88 pregnant women visiting midwiferies, obstetrics and gynecology, and baby fairs in Seoul and Gyeong-Gi area. Data for this study was collected from November 28, 2015 to January 6, 2016 for 40 days. The collected data analyzed mean, standard deviation, t test, ANOVA, and chi-square by using SPSS 23.0. Result Results show that there is a significant difference in the perception, attitude, and experience of the two-sample groups in the use of CAT. The question of “what is most necessary when applying CAT in a hospital clinical environment” for the perception criteria came out with the results of t=9.980, p<.05. For the attitude, results showed that the answers of pregnant women under the age of 35 displayed a more positive attitude towards CAT. (t=2.421, p<.05) Lastly, in the experience section, pregnant women under the age of 35 showed more CAT use than the other sample group. Conclusion Results have shown that there is a difference in the perception, behavior, and experience between the two sample groups. Therefore further research on the efficacy and the adverse effects of CAT needs to be done.

The use of food frequency questionnaire to estimate dietary intake has become widespread in epidemiologic studies. It has been suggested that knowledge about a person's usual serving size of each food, in addition to consumption frequency, will improve the accuracy of this method. This sutdy was performed to investigate the nutritional status and one serving sizes of commonly consumed dishes in Korean college women. Intakes of dish or food in 156 college women were measured by 7-day wiighed food records in May, 1992 and May, 1993. For each dish or food, variance in one serving size was partitioned into within-person(intraindividual) and between-person(interindividual) components. All nutrient intakes except vitimin A and vitamin C were less adequate. The jamor dish groups which contributed to the most daily nutrient intakes were boiled rice, bread, fruits, dairy product, and biscuit and snack groups. In more than 50% of dishes, the within-person variation was greater than between-person variation. And the variety and amount of food which was used in one dish were too variable to make standard recipe.

김지연,최경운,설미영 부산대학교 병원 암연구소 2007 부산대병원학술지 Vol.- No.21

PURPOSE: Galectin-3 is a beta-galactoside-binding protein that has been reported to be expressed preferentially in thyroid malignancies. HBME-l is a monoclonal antibody that was raised to recognize an antigen on the surface of mesothelial cells. This preliminary study was designed to substantiate this finding further and to establish a presurgical diagnostic modality of differentiating between benign and malignant thyroid neoplasms by analyzing galectin-3 and HBME-l expression in fine-needle aspirates. SUBJECT AND METHODS: The expression of galectin-3 and HBME-1 were examined immunohistochemically in total of 34 specimens: 12 papillary carcinomas, 4 follicular carcinomas, 8 follicular adenomas and 10 goiters. RESULTS: The positive rate of galectin-3 and HBME-l were 100%(12/12) and 66.7%(8/12) in papillary carcinoma, 50%(2/4) and 75%(3/4) in follicular carcinoma, 50%(4/8) and 12.5%(1/8) in follicular adenoma, 30%(3/10) and 10%(1/10) in goiter, 39%(7/18) and 11.1%(2/18) in benign lesion, and 87.5%(14/16) and 68.8%(11/16) in malignant lesion, respectively. The sensitivity, specificity, positive predictive value and negative predictive value for galectin-3 were 87.5%, 61.1% ,66.7% and 84.6% and for HBME-1 were 68.8% ,88.9%,84.6% and 76.2%, respectively. CONCLUSIONS: Galectin-3 serves as an excellent sensitive marker of papillary carcinoma and HBME-1 as a specific marker of malignant thyroid tumor.

김효정,홍은순,오지영,홍영선,성연아 대한내분비학회 2002 Endocrinology and metabolism Vol.17 No.5

연구배경: DHEA는 안드로겐 전구체로서 연령 증가에 따라 감소한다. 남성에서 DHEA는 인슐린저항성 및 심혈관질환에 대한 보호 작용을 하는 것으로 알려져 있으나 여성에서는 인슐린저항성과 심혈관질환에 대한 DHEA의 역할은 정립되어 있지 않다. 본 연구는 여성에서 인슐린저항성과 심혈관질환에서 DHEA의 역할을 규명하고자 시행하였다. 방법: 지역사회에서 무작위 추출된 471명의 여성을 대상으로 DHEA보다 반감기가 길고 일중 변동이 적은 것으로 알려져 있는 DHEAS의 농도를 방사면역측정법으로 측정하였다. DHEAS 농도와 인슐린저항성증후군 및 이 증후군을 구성하는 인자들과의 연관성을 관찰하였다. 결과: 1. 인슐린저항성증후군 인자의 빈도는 비만 25.3%, 내당능장애 8.5%, 고혈압 21.9%, 이상지질혈증 6.2%이었으며 인슐린저항성증후군의 빈도는 16.5%이었다. 2. DHEAS는 연령(r=-0.47, p<0.001), 수축기혈압(r=-0.18, p<0.001), 이완기혈압(r=-0.10, p<0.05), 공복혈당(r=-0.10, p<0.05), 포도당부하 2시간 혈당(r=-0.12, p<0.01), 및 중성지방(r=-0.16, p<0.01)과 의미있는 음의 상관관계가 있었다. 3. DHEAS 농도를 사분위수로 나눈 후 연령을 보정한 후 인슐린 저항성증후군 구성요소의 빈도를 관찰하였을 때 DHEAS 농도 감소에 따라 고혈압의 빈도가 유의하게 증가하였다.(p<0.05). 4. 연령(p<0.0001) 및 체질량지수(p<0.05)가 DHEAS에 영향을 주는 인자로 작용하였다. 5. 연령을 보정한 후 낮은 DHEAS농도는 인슐린저항성증후군의 위험인자로 작용하지 않았다. 결론: 여성에서 혈청 DHEAS 농도는 혈압, 혈당 및 혈청 지질 농도와 음의 상관관계가 있었으며, 연령을 보정한 후 DHEAS 농도가 감소함에 따라 고혈압의 빈도가 증가하는 것으로 보아 최소한 DHEAS는 인슐린저항성증후군에 대해 위해 작용을 가지지는 않는 것으로 생각된다. 그러나 DHEAS의 인슐린저항성증후군 및 심혈관질환에 대한 보호 작용을 증명하기 위해서는 이들 대상자를 전향적으로 추적 관찰하여 인슐린저항성증후군 및 심혈관질환의 발생과 DHEAS의 관계를 규명해야 할 것이다. Background: Dehydroepiandosterone (DHEA) is an androgen precursor, and is known to be decreased by the aging process. DHEA has been known to have a protective effect on insulin resistance and cardiovascular disease in men, but remains controversial in women. The aim of this study was to elucidate the role of DHEA on insulin resistance, and the risk for cardiovascular disease, in women. Methods: We analyzed the relationship between DHEA sulfate (DHEAS), known to have a longer half-life and less diurnal variation than DHEA, and insulin resistance syndrome (IRS) in 471 non-diabetic women from an urban community diabetes prevalence study. Serum DHEAS concentrations were measured using a commercially available radioimmunoassay kit. Results: 1. the frequencies of obesity, impaired glucose tolerance, hypertension and dyslipidemia were 25.3, 8.5, 21.9 and 6.2%, respectively, and the frequency of IRS was 16.5%. 2. DHEAS was significantly inversely correlated with age (r=-0.47, p<0.001), systolic blood pressure (r=-0.18, p<0.001), diastolic blood pressure (r=-0.10, p<0.05), fasting serum glucose (r=-0.10, p<0.05), postchllenge 2 hour glucose (r=-0.12, p<0.01) and triglycerides (r=-0.16, p<0.01). 3. As serum DHEAS concentrations, by quartiles, were decreased, the age-adjusted frequency of hypertension was significantly increase (p<0.05). 4. A Multiple linear regression analysis revealed that DHEAS was significantly associated with age (p<0.0001) and BMI (p<0.05). 5. A Logistic regression analysis showed that DHEAS was not associated with IRS after adjustment for age. Conclusion: DHEAS is inversely associated with age. DHEAS has no harmful effect, and may even have a protective role, on insulin resistance syndrome. Prospective examinations of DHEAS and insulin resistance syndrome in women are needed to confirm the mechanism for the association between DHEAS and the development of cardiovascular disease (J Kor Soc Endocrinol 17:675∼684, 2002).

Graves 병과 혈청 면역글로불린-E의 연관성

김현영,박기룡,김성훈,김지연,송수근,최영식,박요한 대한내분비학회 2002 Endocrinology and metabolism Vol.17 No.5

연구배경: Graves 병은 미만성 갑상선종, 갑상선기능한진, 안구침법 등을 특징으로 하는 자가면역성 질환으로, 갑상선자극호르몬 수용체에 대한 자가항체(TRAb)가 갑상선을 자극하여 발생된다. TRAb는 Graves병 환자의 약 85%이상에서 검출되며 활성화된 TRAb는 대부분 IgE로 알려져 있다. 그러나 최근 Graves병 환자의 갑상선조직과 안구조직에 IgE의 침착과 꽃가루 등에 의한 알레르기성 비염으로 인해 Graves병이 발생하거나 재발된 견우가 보고되어 Graves병의 병인에 IgE의 연관성이 제기 되고 있으나, 국내에서는 이에 대한 연구가 드물다. 본 연구에서는 Graves병에서의 혈청 IgE농도와 Graves병의 병기와의 관계 및 TRAb와 IgE 농도와의 연관성을 살펴보고자 하였다. 대상 및 방법 : 2000년 4월 1일부터 7월 1일까지 고신의료원 내분비내과를 방문한 환자 중 Graves병 46예, 만성갑상선염 6예 및 고신의료원 건강증진센터를 방문한 환자 중 갑상선질환의 병력이나 가족력 및 알레르기성 비염의 병력이 없는 35예의 정상대조군을 대상으로 연구를 시행하였다. TRAb는 갑상선자극호르몬 결합 억제 면역글로불린(TBII)으로 측정하였으며, IgE는 효소면역분석법으로 측정하였다. 결과: IgG인 TBII는 Graves병에서 만성갑상선염과 대조군에 비해 높았으며, IgE 평균농도는 Graves병에서 598.1±1112.9U/mL로 만성갑상선염 환자의 98350±79.7U/mL, 대조군 161.72±194.4U/mL에 비해 높았다(p<0.05). Graves병에서 알레르기성 비염의 발병율은 10.9%(5/46)였으며, Graves 병에서의 혈청 IgE 농도는 알레르기성 비염의 병력이 있는 경우 903.1±1152.2U/mL로 없는 경우 560.8±1117.0U/mL보다 높은 경향을 보였다. Graves병의 병기에 따른 TBII와 IgE 농도의 변화를 항갑상선제로 치료하지 않은 군(비치료군)과 치료한 군(치료군) 및 재발군으로 나누어 비교하였을 때, TBII는 치료군(7.4±18.6%)에 비해 비치료군(49.9±23.9%)과 재발군(21.1±3.1%)에서 높았으며(p<0.05), 혈청 IgE치도 치료군(233.8±432.7U/mL)에 비해 비치료군(758.6±1250.0U/mL)과 재발군(1198.5±1952.1U/mL)에서 높은 경향을 보였다. 항갑상선제로 치료한 치료기간에 따른 TBII와 IgE 농도 변화에서, TBII는 비치료군(49.9±23.9%)과 1년 미만 치료군(24.8±3.8%)에서 1년 이상 치료군(2.22±1.97%)에 비해 높았으며(p<0.05), 혈청 IgE 농도는 비치료군(758.6±1250.2U/mL)에서 1년 미만 치료한 군(158.3±91.5U/mL)과 1년 이상 치료군(252.7±483.4U/mL)에 비해 높았으나 유의하지는 않았다. 결론: Graves 병에서 IgE 농도는 증가되어 있었으며, Graves 병의 각각 다른 병기에서의 혈청 IgE 농도의 변화는 Graves qudd의 경과에 영향을 미치는 IgG인 TBII치의 변화와 유사한 경향을 보였다. 그러나 혈청 IgE와 Graves 병과의 연관성을 알아보기 위해서 IgE와 더불어 CD23항원 등의 다른 검사도 병행하는 전향적 연구가 필요할 것으로 생각된다. Background: It is widely believed that Graves' disease is and autoimmune disorder characterized by the presence of the circulation TSH receptor antibody (TRAb). The majority of the activity of TRAb is of the immunoglobulin G(IgG) class. However, other immunoglobulin such as immunoglobulin E(IgE), may play a rloe in the activity. IgE accumulation has been reported to occur in the thyroid gland and ocular muscles of subjects with Graves' disease. Furthermore, it has been noted that recurrence of Graves' disease can be induced by and allergy to pollen. Because an allergy to pollen is commonly associated with IgE, IgE might play a role in the induction of Graves' disease. Therefore, investigated whether IgE was elevated in Graves' disease, and evaluated the potential relationship between the levels of TRAb and IgE Graves' disease. Methods: Forty-six patients with Graves' disease, and 6 with chronic thyroiditis, diagnosed at the Kosin Medical Center between April, 2000 and July, 2000 were included in this study. Thirty-five persons without thyroid disease or a history of allergic rhinitis were used as normal controls. The level or TRAb was measured using thyrotropin binding inhibitory immunoglobulin (TBII). Serum total IgE was measured using as enzymeimmunoassay method. Test for thyroid function, TBII and total IgE were performed in all cases, and the results statistically analyzed. Results: TBII, as IgG, and the serum IgE level were higher in the patients with Graves' disease, and the levels of the latter were 598.1±1112.9U/mL, 98.5±79.7U/mL and controls 161.7±194.4U/mL in the Graves' patients, those with thyroiditis and the controls, respectively (p<0.05). The prevalence of allergic rhinitis in Graves' disease was 10.9%. The serum IgE level in Graves' disease with, and without, allergic rhinitis were 903.1±1152.2U/mL and 560.8±1117.0U/mL, respectively, although there was no significancant difference between the two groups. According to the clinical stage, the serum TBII level was higher in the untreated Graves', and relapsed patients 49.9±23.9% and 21.1±3.1%, respectively, than in the treated group, 7.4±18.6% (p<0.05). The serum IgE level was higher in the untreated Graves' and relapsed patients 758.6±1250.2U/mL and 1198.5±1952.1U/mL, respectively, than in the treated group 233.8±432.7U/mL, although this was not significant. According to the duration of treatment, the serum TBII levels were higher in the untreated Graves' patients, and those treated for less than 1 year, than in those treated for more than 1 year, with values of 49.9±23.9, 24.8±3.8 and 2.22±1.97%, respectively (p<.05). The serum IgE level was higher in the untreated Graves' disease (758.6±1250.2U/mL) than in the groups treated for less than 12 months (158.3±91.5U/mL) and more than 12 months (252.7±483.4U/mL), but the differences were not significant. Conclusions: The concentration of IgE was high in Graves' patients, and although not statistically significant, the serum igE level in Graves' patients with allergic rhinitis was higher than those without. With regard to the clinical stage of Grave's disease, the change in the IgE level tended to follow that of the TBII. Further study will be required to define the possible role of IgE in the pathogenesis in Graves' disease (J Kor Soc Endocrinol 17:640∼648, 2002).
