Background: Atopic dermatitis (AD) is a chronic disorder, with a vicious cycle of repetitive inflammation and deterioration of the epidermal barrier function. Adiponectin, an adipokine, has anti-inflammatory effects on various metabolic and inflammatory disorders. Recently, its level was found to be reduced in serum and tissue samples from AD patients. Objective: We aimed to investigate the effects of adiponectin on epidermal inflammation and barrier structures in AD skin. Methods: A three-dimensional in vitro epidermal equivalent model mimicking AD was obtained by adding an inflammatory substance cocktail to normal human epidermal equivalents (HEEs). The expression of epidermal differentiation markers, primary inflammatory mediators, and lipid biosynthetic enzymes was compared between adiponectintreated AD-HEEs, untreated control AD-HEEs, and normal HEEs. Results: Adiponectin co-treatment 1) inhibited the increase in mRNA expression of major inflammatory mediators (carbonic anhydrase II, neuron-specific NEL-like protein 2, thymic stromal lymphopoietin, interleukin-8, tumor necrosis factor-alpha, and human beta-defensin-2) from keratinocytes in AD-inflammatory HEEs, 2) enhanced the expression of lipid biosynthetic enzymes (fatty acid synthase, HMG CoA reductase, and serine-palmitoyl transferase), and 3) promoted the expression of differentiation factors, especially filaggrin. We also found that the expression of adiponectin receptor-1 and -2 decreased in the epidermis of chronic AD lesion. Conclusion: Activation of the adiponectin pathway is expected to enhance epidermal differentiation and barrier function as well as attenuate inflammatory response to AD as a therapeutic approach.

감 품종별(도근조생, 고종시, 갑주백목, 차랑, 월하시, 상주둥시)로 감꽃을 개화기에 채취하여 동결건조 분말화한 감꽃분말에 함유된 유효성분을 분석, 비교하였다. 조지방 함량은 도근조생이 57.26%로 가장 높은 값을 보였으며, 유리당 조성은 fructose가 95~310 mg%, glucose는 75~281 mg%, sucrose가 7~28 mg%의 함유량을 나타내었고, 유기산 중 malic acid가 갑주백목(6월4일)에 225 mg%로 가장 많았고, tartaric acid도 189 mg%로 가장 많았다. 유리아미노산 중 hydroxy-L-proline은 월하시에 25.33 mg%, L-citrulline은 상주둥시(5월28일)가 58.83 mg%, L-threonine은 상주둥시(5월28일)가 11.88 mg%로 가장 많았다. 페놀산으로 caffeic acid는 갑주백목(6윌4일)이 1946 μg/100 g, phydroxybenzoic acid는 상주둥시(5월29일)가 417.8 μg/100 g, protocatechuic acid는 갑주백목(6월1일)이 181.1 μg/l00 g으로 가장 많았다. 따라서 감꽃에도 감이나 감잎에 못지않게 유용한 식품성분들과 기능성 성분들이 다량 함유되어 있어 새로운 식품 및 기능성 신소재로서의 가치가 매우 높다고 할 수 있다. This study was carried out to analyze useful components in freeze-dried persimmon flower powder made from six cultivars. The cultivars were Dogunjosang, Kojongsi, Kabjubaekmok, Chalang, Weolhasi and SangjuDungsi. Powder of persimmon flower was prepared by milling after freeze drying at -70℃. Crude lipid was the highest in Dogunjosang (57.26%). Major free sugars of the persimmon flowers were fructose (95~310 mg%), glucose (75~281 mg%)and sucrose (7~28 mg%). Major organic acids were malic acid (225 mg% in Kabjubaekmok (Jun. 4th)) and tartaric acid (189 mg% in Kabjubaekmok (Jun. 4th)). Predominant free amino acids were hydroxy-L-proline(25.33 mg% in Weolhasi), L-citrulline (58.83 mg% in SangjuDungsi (May 28th)) and L-threonine (11.88 mg% in SangjuDungsi (May 28th)). Major phenolic compounds in the persimmon flowers were caffeic acid (1,946 μg/100g in Kabjubaekmok (Jun. 4th)), p-hydroxybenzoic acid(418 μg/100g in SangjuDungsi (May 29th)) and protocatechuic acid(181 μg/100g in Kabjubaekmok(Jun. 1st)). The results suggest that persimmon flowers be potential materials as useful food ingredients.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

The purpose of this study is to examine the relationship between the time for leisure of housewives and their age and is to provide a guideline which help housewives to spend their time for leisure more actively, variously, efficiently. Form the data collected from 200 housewives aged above 30 years in Seoul, We come to the following conclusions. First, housewives spend more than 100,000 won per month for leisure and get information from television or newspapers. In addition, they enjoy yoga and health club with their friends. Second, the time for leisure is not sufficient, especially on weekend. On weekdays and Saturdays, many housewives spend 1 or 2 hour for leisure. On Sundays and holidays, however, they spend 2 or 3 hours. Finally, housewives for all ages are not satisfied with their time for leisure. On weekdays, many housewives aged between 30 and 40 years spend 1 or 2 hours and many housewives age between 40 and 50 years spend more than 2 hours. On Saturdays, however, housewives for all ages spend 1 or 2 hours and they spend 2 or 3 hours on Sundays.

김영건,김진희,전준식,송치운,송민호 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.2

Multiple abnormalities of lipoprotein metabolism exist in patients with diabetes mellitus that could contribute to their enhanced susceptibility to atherosclerosis. Acipimox(5-methyl-pyrazine carboxylic acid 4-oxide, Farmitala Carlo Erba, Milano Italy) is a new potent and long acting(8h) antilipolytic agent, which has been derived from nicotinic acid. By lowering plasma and possibly skeletal muscle concentrations of non-esterified fatty acid, Acipimox may have a potential beneficial effect on glucose metabolism in patients with non-insulin dependent diabetes mellitus. The aim of this study was to evaluate the acute effect of Acipimox on hyperlipidemia associated with non-insulin dependent diabetes mellitus. 18 patients with non-insulin dependent diabetes mellitus were in the study. They had fasting plasma triglyceride concentrations above 250 mg/dl and cholesterol concentrations above 240 mg/dl. The level of triglyceride, cholesterol and glycated hemoglobin were significantly reduced after 8 weeks treatment of Acipimox. Adverse effects were noted in 3 patients, but it was transient with the course of administration. Acipimox is an effective and safe drug for the management of hyperlipidemia associated with non-insulin dependent diabetes mellitus.

In this paper, we consider a problem of determining optimal credit period and ordering lot size from the perspective of supplier. We assume that a supplier knows how the retailer determines the unit retail price and order size to maximize his/her profit when the supplier offers a trade credit for the product. Two widely used demand function, in which we assume that demands are decreasing function of the retail price, are used in this study. Mathematical models for the supplier-retailer system are developed and a solution procedure is presented which shows how to achieve an optimal length of trade credit and procurement lot size for the supplier. A sensitivity analysis for the variable that is related to the procurement lot size the supplier is also carried out.

목적 : 본 연구는 중환자실 환자 및 의료종사자에서 검출된 MRSA의 역학조사에 신속하고 간편한 방법인 random amplified polymorphic DNA (RAPD)의 유용성을 평가하고자 하였다. 재료 및 방법 : 1998년 10월부터 12월 및 2001년 5월부터 7월까지 동아대학교병원 중환자실 입원 환자 및 의료종사자의 검체 각각 10, 15예 및 8, 5예를 대상으로 mecA gene의 유무와 항균제 감수성 검사를 실시하고, 3가지 primer를 이용하여 RAPD를 시행하였다. 결과 : 환자에서 분리된 MRSA 25주 중 21주(84%)와 의료진에서 분리된 13주 중 12주(92%)가 mecA 양성이었고, mecA 양성 MRSA를 RAPD로 분석한 결과 모두 18가지 유형으로 분류되었다. 결론 : RAPD 방법을 이용한 유전자 형별 분석은 MRSA의 균주 분별에 유용하며, 또한 중환자실에서 유행 발생한 MRSA의 신속한 역학조사에 유용할 것으로 생각한다. Background : The random amplified polymorphic DNA (RAPD) analysis was investigated to see if this method could be a useful tool for monitoring of epidemic outbreaks of methicillin-resistant Staphylococcus aureus (MRSA) among patients and healthcare workers (HCW) in the intensive care units (ICU). Methods : Thirty-eight MRSA strains were isolated from patients and HCW in Dong-A University Hospital ICU from October, 1998 to December, 1998 (10 patients and 8 HCW) and May, 2001 to July, 2001 (15 patients and 5 HCW). All strains were typed according to antimicrobial susceptibility and RAPD analysis patterns. mecA genes were detected using polymerase chain reaction (PCR). Results : Twenty one of 25 (84%) and 12 of 13 (92%) MRSA, isolated from patients and HCW, respectively, were mecA positive. mecA positive MRSA were classified into 18 different types by RAPD analysis. Conclusion : DNA fingerprinting using RAPD analysis is a simple, effective, and rapid method for discriminating MRSA strains, and may be applicable in detecting outbreaks of S. aureus infections in the ICU.
