Objectives: The aim of the study was to investigate the relationship between oriental obesity pattern, life habitual factors(eating attitude, physical activity) and psychological factors(depression, stress, self-esteem) in korean obese and overweight women. Methods: This study was performed in obese and overweight(BMI ${\geq}$ 23 kg/$m^2$) women in Korea (n=56). Simple anthropometry including weight, BMI, waist circumference, BIA(bioelectrical impedance analysis) were done. To assess psychological factors, the Rosenberg self-esteem scale (SES) questionnaire, Beck depression inventory (BDI) questionnaire and stress response inventory (SRI) questionnaire were administered. Regarding diet, Korean eating attitude test(KEAT-26) was done. International physical activity questionnaire(IPAQ) was administered for exercise and physical activity intensity and quantities. All values were verified using correlation analysis. Results: 1. The subjects had stagnation of the liver qi>food accumulation>yang deficiency>blood stasis>spleen vacuity in the order. 2. Stagnation of the liver qi score had significant relationships with self-esteem(r=-0.520, p<0.05) and depression(r=0.688, p<0.01) in stagnation of the liver qi group. There was a relationship between food accumulation score and eating attitude(r=0.784, p<0.01) in food accumulation group. 3. Lean mass had a significant relationship with self-esteem(r=0.434, p<0.05) fat mass had a significant relationship with stress (r=0.633, p<0.01) and in stagnation of the liver qi group. 4. Physical activity had significant relationships with lean mass(r=0.628, p<0.01) and with fat mass(r=-0.478, p<0.05) in group. Conclusions: This study maintained that psychological factors play major roles in obesity with symptoms of stagnation of the liver qi and life habit(dietary factors and physical activity) in food accumulation.

35 theses conducted in Korea on the topic of senescence or anti-oxidant were classified on the basis of research methods, animals used for the experiments, and research items. Evaluating these research works with respect to the Free Radical Theory, the following conclusions were reached. 1. Of the 17 theses written in the Oriental medicine aspect, three theses used a single herb, nine theses used a complex prescription, four theses concentrated on the usage of the medicinal acupuncture, and one research paper focused on using scientific components. Common objection of these papers were on the verification of the efficacy of herbs. 2. Of the 18 these written in the Western medicine aspect, five theses used a single drug, seven theses conducted a research on the changes due to senescence, and 6 papers were on variety of topics. The main focus of these works were on the mechanism and pathology related to the senescence rather than on the suppression of senescence. 3. Among the theses written in the Oriental medicine perspective, a total of 48 herbs were utilized. 26 of these herbs has a tonification function on the Kidney. Six out of nine complex prescription mentioned above has a function of tonifying the Kidney. 4. With respect to the research subjects used on the experiments, 8 theses have used Senescence-Accelerated mice, 13 theses have used Sprague-Dawley mice, and remaining 7 papers have used human or other animals. 5. These are the categorization of the research items used: the weight (11) and weight changes of the visceral organs (9), the measurement of the content of peroxide-disease (9), the measurement of enzyme vitality (21), the blood and urine test (10), the experiment concerning immune system (3), the influence on the hepatic capability of metabolizing foreign substance (3), the effect on hepatic cell protection (3), the measurement of both the suppression of Free Radical and ability to create Free Radical (2), the measurement of effect of suppresing MDA(malondialdehyde) (4), the effect of eliminating DPPH Radical (2), and experiements about the functions (2). 6. The rate of vitalization of well known anti-oxidants such as Superoxide dismutase (SOD), Protein-bound SH, Nonprotein-bound SH, Glutathione(GSH), Catalase, and etc. were tested in 17 theses. Considering the conclusions mentioned above, the theses related to the senescence published in Korea elected different animals used for experiments, research items and the methods of research, the end result seems to be a lack of objectivity. Thus, I would argue that research methods to overcome such a deficiency need to be developed systematically.

This study was conducted for 39 patients who are recipients of allogeneic hemopoietic stem cell transplantation at BMT ward of St. Mary's hospital affiliated to Catholic University of Korea from April to September 1999. The subjects were devided into two groups; those who received both TEl and chemo therapy as conditioning regimen (TEl group). and those who used chemo agents as singular conditioning regimen (chemo group). The oral intake status of the two groups were compared through physical assessment and blood chemistry exam of the subjects, and factors influencing their nutritional change and oral intake were explored in each stage of the transplantation (six stages: admission, conditional stage, date of transplantation, one week after transplantation, two weeks after transplantation, and three weeks after transplantation). The prior aim of the study was to provide baseline data to minimize delayed treatment from nutritional deficiency of the subjects. The results were as follows: 1. TBI group was significantly decreased of oral calorie intake in two weeks after transplantation compared to admission and conditioning stage while that of chemo group was significantly decreased on the date of transplantation. 2. TBI group was significantly decreased of protein intake in two weeks after transplantation compared to admission and conditioning stage. In chemo group, protein intake was significantly decreased on the date of transplantation compared to admission. It was remarkable that TBI group showed lesser protein intake than chemo group. 3. Both group were significantly decreased of BMI in one week and three weeks after transplantation compared to admission. TBI group showed significantly higher BMI than chemo group. 4. Both group were significantly decreased of Triceps Skinfold Thickness (TST)on the date of transplantation compared to admission stage. 5. TBI group was significantly decreased of mid-arm muscle circumference (MAMC) in two weeks after transplantation compared to admission, conditioning, date of transplantation. 6. TBI group was significantly decreased of albumin level in two weeks after transplantation compared admission stage. In chemo group, it was significantly decreased on the date of transplantation compared to admission, three weeks after the transplantation. 7. TBI group was significantly decreased of transferrin level in two weeks after transplantation compared admission, conditioning, date of transplantation and one week after transplantation. In chemo group, it was decreased of transferrin level in 3 weeks after transplantation. 8. Oral intake of TEl group was impacted by vomiting before transplantation and gingivitis after transplantation. In chemo group, it was impacted by vomiting before transplantation and by two factors, gingivitis and nausea, after transplantation. The results showed oral calorie intake was not different between the two groups while protein intake was significantly lower in TBI group than chemo group. Oral intake was significantly impacted by vomiting before transplantation in both groups, but affected by oral gingivitis in TBI group and gingivitis and nausea in chemo group after transplantation. This findings present that standardized strategies to manage nutrition and gingivitis more effectively are desperately needed to enhance oral intake and protein intake of patients who receive TBI as conditioning regimen.

Background and Purpose : Most diagnostic method for lumbago were invasive and complex. So we need to simplify and objectify diagnostic method for lumbago. Some study with EAV which is one of Physiological Signal Measuring Instruments, report significantly result as objective diagnostic method for other clinical symptom. By using EAV, we have obtained some physiological signal data from meridian-acupoints of 31 lumbago cases. Objective and Methods : This study researched into the clinical statistics for 31 case who ware in lumbago, and they ware treated with oriental medical care at the Dong-shin university oriental hospital during 6 month from June 1 2001 to November 10 2001. The data were analyzed and interpreted to compare with traditional differentiation of symptom-complexes, then further evaluated as the Five Evolutive Phases to make them differentiated. The EAV valus of Five Evolutive Phases were identified with the sequence of wood(木), fire(火), earth(土)steel(金), water(水). Results and Conclusion : These values of physiological signal were identical with standard differentiation of symptom-complexes of lumbago which is the main cause of deficiency of Qi and blood of the kidney and bladder. Among Five Evolutive Phases, Earth and wood values were increased, steel, fire and water were decreased significantly. This data imply the possibility of somewhat generalization from measuring instruments.

Insulin signaling is coordinated by insulin receptor substrates (IRSs). Many insulin responses, especially for blood glucose metabolism, are mediated primarily through Irs-1 and Irs-2. Irs-1 knockout mice show growth retardation and insulin signaling defects, which can be compensated by other IRSs in vivo; however, the underlying mechanism is not clear. Here, we presented an Irs-1 truncated mutated mouse ($Irs-1^{-/-}$) with growth retardation and subcutaneous adipocyte atrophy. $Irs-1^{-/-}$ mice exhibited mild insulin resistance, as demonstrated by the insulin tolerance test. Phosphatidylinositol 3-kinase (PI3K) activity and phosphorylated Protein Kinase B (PKB/AKT) expression were elevated in liver, skeletal muscle, and subcutaneous adipocytes in Irs-1 deficiency. In addition, the expression of IRS-2 and its phosphorylated version were clearly elevated in liver and skeletal muscle. With miRNA microarray analysis, we found miR-33 was down-regulated in bone marrow stromal cells (BMSCs) of $Irs-1^{-/-}$ mice, while its target gene Irs-2 was up-regulated in vitro studies. In addition, miR-33 was down-regulated in the presence of Irs-1 and which was up-regulated in fasting status. What's more, miR-33 restored its expression in re-feeding status. Meanwhile, miR-33 levels decreased and Irs-2 levels increased in liver, skeletal muscle, and subcutaneous adipocytes of $Irs-1^{-/-}$ mice. In primary cultured liver cells transfected with an miR-33 inhibitor, the expression of IRS-2, PI3K, and phosphorylated-AKT (p-AKT) increased while the opposite results were observed in the presence of an miR-33 mimic. Therefore, decreased miR-33 levels can up-regulate IRS-2 expression, which appears to compensate for the defects of the insulin signaling pathway in Irs-1 deficient mice.

Zinc is one of the essential trace elements in the living organism for growth and health. The first identified metalloenzyme, carbonic anhydrase, is a zinc compound and several others have been described since. Among zinc deficiency syndromes in animals porcine parakeratosis has been successfully treated with zinc supplements, and in man a syndrome of anemia, hypogonadism, hepatosplenomegaly, and dwarfism, prevalent in parts of Iran and Egypt, has been ascribed to lack of zinc in the diet. Dietary zinc excess in the rat is manifested by a hypochromic, microcytic anemia, poor growth, reduction in liver catalase and cytochrome oxidase. The present study is an attempt to delineate the changes of tissue contents of trace elements, especially of iron, copper and zinc in liver and kidneys of the rats. Weanling albino rats, weighing 60 to 80gm. were used in this experiments. The rats were housed in cages with aluminum floors and received feed and distilled water ad libitum. Animals were divided into three groups, control, low zinc diet and high zinc diet groups. The high zinc diet group was subdivided into 0.5% Zn and 0.7%Zn groups. The supplementary copper or iron was added to the high dietary zinc groups. The animals were sacrificed and the tissues were washed several times with deionized water. The wet digested samples were analyzed by Hitachi Model 207 atomic absorption spectro-photometer for the determination of iron, copper and zinc in the liver and kidney. Hemoglobin level in the blood was measured by cyanmethemoglobin method. The results of this study are as follows: 1) All rats fed high zinc diets and low zinc diets gained less weight than control. Weight gain was not improved by the supplementary copper or iron and both. 2) Hemoglobin concentration was decreased significantly in the rats fed high zinc diets and less in the low zinc diet. Supplementary copper and iron to the higher zinc diet appeared to give some improvement of anemia. 3) The iron contents of the liver and kidneys were significantly decreased in the high zinc groups and the reduction was more significantly in the rats receiving higher zinc diet (0.7%). The supplementary copper caused a further depression of liver iron. On the other hand, the iron, added to the high zinc diet lessoned the severity of the decrease in liver iron and caused kidney iron to be maintained almost at the level found in the rats fed by zinc and supplementary copper diet. 4) High zinc diets did not change copper content of the liver and kidney. Supplementary copper elevated the concentration in the liver and kidney and added iron had no effect on the accumulation of copper in the liver and kidneys. 5) The high zinc diets caused marked increases of zinc content in the liver and kidney. Supplementary iron to the high zinc diet caused increases of zinc contents of liver and kidneys.

Objective: Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow obstruction that is only partly reversible, inflammation in the airways, and systemic effects. This study aimed to investigate the association between low peripheral oxygen saturation levels (SpO₂), and composite indices predicting death in male patients with (COPD). Method: A total of 140 participants with post-bronchodilator FEV₁/FVC ratio less than 0.7 were included. Three composite indices (ADO, DOSE, BODEx) were calculated using six variables such as age (A), airflow obstruction (O), body mass index (B), dyspnea (D), exacerbation history (E or Ex), and smoking status (S). Severity of airflow limitation was classified according to Global Initiative for Obstructive Lung Disease (GOLD) guidelines. SpO₂ was measured by pulse oximetry, and anemia and iron deficiency were assessed based on blood hemoglobin levels and serum markers such as ferritin, transferrin saturation, or soluble transferrin receptor. Results: Participants with low SpO₂ (<95%) showed significantly lower levels of %FEV₁ predicted (p=0.020) and %FEV₁/FVC ratio (p=0.002) compared to those with normal SpO₂ levels. The mMRC dyspnea scale (p<0.001) and GOLD grade (p=0.002) showed a significant increase in the low SpO₂ group. Receiver Operating Characteristic analysis revealed higher area under the curve for %FEV₁ (p=0.020), %FEV₁/FVC(p=0.002), mMRC dyspnea scale (p=0.001), GOLD grade (p=0.010), ADO (p=0.004), DOSE (p=0.002), and BODEx (p=0.011) in the low SpO₂ group. Conclusion: These results suggest that low SpO₂ levels are related to increased airflow limitation and the composite indices of COPD.

급성심장사는 돌연 예기치 못한 심장질환에 의해 갑자기 사망하는 것으로, 법의부검 실시 전 초기 변사현장에서 외피 검시 과정 중 육안적으로 법의학적 사인 추정을 위한 명확한 소견 관찰이 어려운 점으로 인해 법의부검에서 심근 조직의 현미경적 변화 관찰을 통한 진단이 제안되고 있다. 그러나 검사시간, 비용, 편의성 등 변사사건 현장 외표 검시를 통한 사인추정 실무현장에 적용하는데 문제점을 드러내고 있다. 이에 본 연구에서는 임상 병원 진단검사의학에서 급성심근경색 환자의 진단 검사에 이용하는 심장표지물질 간이 검사 키트를 이용하여 사후 혈액에서 심장표지물질 myoglobin, CK-MB, cTn I를 측정하는 간이 검사가 내인성급사인 급성심장사를 사후 진단하는데 유용하게 이용될 수 있는지를 알아보고자 하였다. 외피 검시 및 간이검사 결과 비외상성 급성심장사로 추정되는 실험군 30예를 법의 부검 결과와 비교한 결과 23예(76.7%)에서 양성, 대조군 10예 중 뇌혈관질환 추정 4예 모두 음성, 알코올 및 약물 중독 1예, 산소결핍 질식사 1예에서 양성을 보였다. 심장표지물질 간이 검사의 민감도와 특이도는 각각 76.7%, 80.0%의 유의한 결과를 보여 변사사건 현장에서 변시체의 과거병력, 현장상황 및 사후시간 등을 종합적으로 고려하여 사후 급성심장사의 의심, 추정 진단에 보조적 방법의 하나로 유용하게 이용될 수 있을 것으로 사료된다. 향후 심장표지물질(myoglobin, CK-MB, cTn I)의 개별물질 특성에 의한 혈액 내 최초 발현 및 소멸시간, 시간 경과에 따른 농도 차이 등에 대한 선행연구 결과를 기초로 사망원인 규명 등 사건 해결에 필요한 사후경과시간 추정을 위한 사후 시간대 별 심장표지물질 농도에 대한 추가적인 연구가 계속 되어야 할 것이다.

목 적 : Hyper IgM syndrome(HIGM)은 크게 세 부류로 나누는데, CD40L 분자의 돌연변이로 초래되며 X-linked로 유전되는 형태를 HIGM1이라고 하고, 상염색체성 열성 형태로 유전되면서 CD40L는 정상적으로 표현되는 형태로 activation-induced cytidine deaminase(AID) 유전자에 이상 때문에 오는 경우를 HIGM2로 분류하고 있다. 다른 한 부류는 X-linked HIGM 증후군의 매우 드문 한 형태로서 발한 저하성 외배엽 이형성증이 동반된 경우로, 이 질환은 전사인자인 nuclear factor ${\kappa}B$의 활성화에 관여하는 nuclear factor ${\kappa}B$ essential modulator를 coding하는 유전자의 돌연변이 때문에 오는 것으로 알려져 있다. 연구자들은 HIGM2와 유사하지만 AID 유전자에 변이는 없는 새로운 형태의 HIGM 환자의 말초 B세포를 이용하여 병인을 조사하고자 본 연구를 시도하였다. 방 법 : 환자의 말초혈액 단핵구를 분리하고, EBV로 immortalization을 시켜 Cycle TEST PLUS DNA Reagent kit를 이용하여 cell cycle을 분석하였다. 환자의 말초혈액 T 세포에서 CD40L의 표현을 immunostaining으로 알아보고, RNA를 추출하여 RT-PCR을 하고 direct sequencing을 통하여 CD40L 유전자의 돌연변이 부위를 찾아보았다. 아울러 AID 유전자의 돌연변이를 찾기 위하여 같은 방법으로 sequencing하고 조사하였다. 환자의 림프절을 병리학적인 검사를 시행하고 CD3, CD23, CD40, Fas-L, bcl-2, BAX의 표현을 알아보기 위하여 immunostaining을 실시하였다. 결 과: 림프절의 광학적 소견은 반응성 여포증식의 소견을 보였으며, 여포와 단구양 증식은 B-세포 표시인자인 L26에 양성을 보였고, 대부분의 형질세포는 IgM에 양성을 보였다. 여포는 CD40, Fas, BAX에 양성반응을 보이고, bcl-2와 Fas-L에 음성반응을 보였다. 말초혈액 B 림프구를 이용하여 cell cycle을 분석한 결과 정상(17.9%)에 비하여 G2/mitosis phase(M3 in figure)가 현저하게 감소(8.5%)되어 있는 양상을 보여주고 있으며, IL-4로 자극한 경우에는 정상인에서 보여주는 양상으로 회복되는 양상을 볼 수 있었다. 단핵수에서 CD40L의 표현은 정상이었고 CD40L 유전자에도 돌연변이는 발견할 수 없었으며, HuAID 유전자에도 돌연변이를 발견할 수 없었다. 결 론 : 환자의 말초혈액 B림프구를 통한 연구 결과, 기존에 보고 되어진 HIGM2 형태와 임상적으로는 비슷하지만, 정상적인 AID유전자를 보이고, G2/mitosis phase가 정상에 비하여 감소된, 새로운 형태의 HIGM이라고 여겨진다.
