In an aging society, there is an increasing possibility of the duplication of the drugs given to patients because they take many kinds of drugs. Among the prescriptions given to the patients who was treated at multiple ambulatory clinics in St. Mary's hospital for one month of September, 2002, in which drugs that has identical or similar effects are prescribed, we analysed and evaluated them by patients' characteristics, kinds of medication, severity of side effects on a case by case basis. More, we assessed the potential additional costs. As a result of this study, the duplication rate turned out to be 6.69% and it was shown that the proportion of the elderly patients over 60 was high. The gastro-intestinal medications took up a large part and most of the cases showed that the danger caused by double taking of medicine was slight, but there were some examples in which the serious side effects were predicted. Expected additional costs were the average 11.349 won and it ranges from the minimum of 56 won to the maximum of 135,720 won. In conclusion, the management of drug histories of the patients who need the plural treatments is very important and the necessity of the individual and professional guidance of taking medicines for the elderly patients is emerged, too.

골수유핵세포의 경내피세포 및 경기질세포 이행 과정에서 류코트리엔 B_(4) 역할과 활성산소종 억제의 영향
문영철,오수아,유은선,최문영,안지영,성주명 이화여자대학교 의과학연구소 2008 EMJ (Ewha medical journal) Vol.31 No.2
Objectives:Leukotriene B_(4)(LTB4) is lipid mediator derived from membrane phospholipids during the process of inflammation, having many roles(ie;inducer of chemotaxis, the production of nitric oxide, transepithelial migration of neutrophil). The major activities of LTB4 include the recruitment and activation of leukocytes, suggesting that it may involve the process for transendothelial migration of nuclear cells in bone marrow environment. Reactive Oxygen Species (ROS) have a cell signaling roles that are involved in signal transduction cascades of numerous growth factor-, cytokine-, and hormone-mediated pathways, and regulate many biological systems. In this present study, we focused on the role of LTB4 and ROS on transmigration of bone marrow nuclear cells across endothelial or stromal cell monolayer. Methods:MS-5, murine stromal cell line cells, or bEnd.3, murine microvascular cell line cells, were grown to confluence on microporous transwell membrane. Murine marrow cells were placed on top of the prepared transwell membrane. The transwells were then seated in wells containing media and LTB4 with or without pretreatment of N-acetylcysteine(NAC), an oxygen free radical scavenger, or diphenylene iodonium(DPI), an inhibitor of NADPH oxidase-like flavoproteins. Cells that migrated through the stromal or endothelial layer into the wells were assayed for transendothelial migration. Results:The numbers of migrated bone marrow nuclear cells through the bEnd.3 were increased by treatment of LTB4(control, 12.5±0.2%;50nM, 22.7±0.9%;100nM, 44.3±1.4%;200nM, 36.3±0.9%;p<0.05). The numbers of migrated bone marrow nuclear cells through the MS-5 were also increased by treatment of LTB4(control, 11.0±0.9%;50nM, 25.7±0.9%;100nM, 35.8±1.8%;200nM, 32.1±0.9%;p<0.05). However, increasing effect of LTB4 to the transmi-gration of bone marrow nuclear cells through the MS-5 or bEnd.3 were inhibited by pretreatment of NAC or DPI. Conclusion:Through our data, it is suggested that LTB4 could induce the transmigration of bone marrow nuclear cells and ROS might be involved on the transendothelial migration of bone marrow nuclear cells by LTB4. It would be very interesting to test the effects of LTB4 and ROS on stem cell mobilization and homing in the future. 류코트리엔 B_(4)(LTB4)는 세포막 인지질로부터 유래된 염증과정에 관여하는 지방매개체이다1-3). LTB4의 주된 역할은 화학주성의 유도, 활성산소의 생산, 백혈구, 특히, 호중구 및 호산구의 이동에 관여하고 있으며, 내피세포와 백혈구의 부착에 중요한 역할을 하는데, 이러한 LTB4의 역할은 케모카인에 의한 백혈구의 이동과 화학주성과 많은 부분에서 유사한 특성을 가진다4-7). 염증반응과 백혈구 이동과 연관된 LTB4의 역할들은 골수내 세포들의 이동 과정에서 다른 시토카인이나 성장인자 혹은 케모카인의 역할과 유사한 점이 많다. LTB4와 비슷한 작용을 가진 여러 케모카인들이 조혈모세포를 포함한 골수내 세포들의 이동과 연관이 있음이 최근 밝혀짐에 따라, LTB4도 골수내 세포의 이동에 관련이 있을 가능성이 있다8-14). 활성산소종(ROS)은 여러 종류의 성장인자, 시토카인, 혹은 호르몬 등으로 유도된 조혈세포내 신호전달체계에 중요한 역할을 하고, 조혈세포내 여러 생명현상의 조절과 관련이 있다15-18). 특히, 염증세포에서 분비된 시토카인 혹은 케모카인들이 세포내 ROS를 증가시키고, 이때 증가된 ROS는 혈관내피세포 단층의 투과성을 증가시켜 백혈구의 경내피세포 이행을 용이하게 한다19-22). 조혈모세포 이식 후 조혈모세포가 말초혈액에서 골수 내로 자리잡는 귀소나, 골수내 조혈모세포를 혈액으로 나오게 하는 가동화의 과정은 매우 복잡하여, 여러 다양한 기전들이 관련이 있지만, 혈관내피세포 및 기질세포와 골수 조혈세포들과의 유기적인 반응과 골수 조혈세포의 경내피세포 이행이 중요한 역할을 한다23)24). 본 연구에서는 골수유핵세포의 경내피세포 및 경기질세포 이행에 LTB4와 ROS가 어떻게 영향을 미치는지 알아보고자 하였다.

여성에서 Dehydroepiandrosterone sulfate와 인슐린저항성증후군의 연관성
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).

<P>The Di(b) antigen usually occurs with high incidence, except in certain Asian and South American Indian populations. In general, hemolysis caused by anti-Di(b) is not severe and its clinical course is benign. We report a Korean neonate with severe hemolytic disease of the newborn caused by anti-Di(b). The phenotype and genotype of the Diego blood group system of the patient and his mother were Di(a+b+) and Di(a+b-), respectively. The mother's serum and eluate from the neonate's erythrocytes contained anti-Di(b). This case was successfully managed with phototherapy and high dose iv immunoglobulin. Since most commercial antibody detection panels do not contain Di(b-) red cells, it is important to consider anti-Di(b) in cases of hemolytic disease of the newborn caused by an antibody against a high frequency antigen.</P>

Inhibition of mouse brown adipocyte differentiation by second-generation antipsychotics
Jee-Eun Oh,조윤미,Su-Nam Kwak,김재현,Kyung Won Lee,Hyosan Jung,정성환,권오주 생화학분자생물학회 2012 Experimental and molecular medicine Vol.44 No.9
Brown adipose tissue is specialized to burn lipids for thermogenesis and energy expenditure. Secondgeneration antipsychotics (SGA) are the most commonly used drugs for schizophrenia with several advantages over first-line drugs, however, it can cause clinically-significant weight gain. To reveal the involvement of brown adipocytes in SGA-induced weight gain, we compared the effect of clozapine, quetiapine, and ziprasidone, SGA with different propensities to induce weight gain, on the differentiation and the expression of brown fat-specific markers, lipogenic genes and adipokines in a mouse brown preadipocyte cell line. On Oil Red-O staining, the differentiation was inhibited almost completely by clozapine (40 μM) and partially by quetiapine (30 μM). Clozapine significantly down-regulated the brown adipogenesis markers PRDM16, C/EBPβ, PPARγ2, UCP-1, PGC-1α, and Cidea in dose- and time-dependent manners, whereas quetiapine suppressed PRDM16, PPARγ 2, and UCP-1 much weakly than clozapine. Clozapine also significantly inhibited the mRNA expressions of lipogenic genes ACC, SCD1, GLUT4, aP2, and CD36 as well as adipokines such as resistin, leptin, and adiponectin. In contrast, quetiapine suppressed only resistin and leptin but not those of lipogenic genes and adiponectin. Ziprasidone (10 μM) did not alter the differentiation as well as the gene expression patterns. Our results suggest for the first time that the inhibition of brown adipogenesis may be a possible mechanism to explain weight gain induced by clozapine and quetiapine.
