Obesity is chronic disease which influenced on health severly. The causes of obesity have been known as life change, lack of excercise, genetic factor, mental and social economic factors. Especially the obesity of women increased the risk of the diseases such as DM, osteoarthritis, cardiovascular disease, breast cancer and infertility. The limitations of the widely used negative definition of health as the absence of disease and WHO's 1946 definition of health as total social, psychological and physical well-being have long been recognized (WHO 1958). The Quality of Life (QoL) includes functional ability, the degree and quality of social and community interaction, psychological well-being as somatic sensation and life satisfaction. I investigated to compare the differences between obese women (n=63), non-obese women (n=37) in clinic and general women (n=43, control) on baseline characteristics and WHO QoL-BREF. The purpose of this study is to assist the diagnosis and treatment of obesity. WHO QoL-BREF is self administered type which consisted of 26 questions. The prospective question is calculated with 5 scores by Likert's method. The results are as follows : The means of physical, psychological, social, overall and total scores of QoL were significant among BMI group (P<0.05). The score of control group (BMI < 25) was higher than other groups significantly (P<0.05). In multiple regression analysis, the variable of high school/below middle school was significant in environmental and overall domain of QoL scores (P<0.05). The variable of college/below middle school was significant in environmental, overall domain and total score of QoL scores (P<0.05). The variable of above university/below middle school was significant in physical health, environmental, overall domain and total score in QoL scores (P<0.05). The variable of Health perception (moderate/bad) was positively significant in physical health, environmental, overall domain and total score of QoL scores (P<0.05). The variable of Health perception (good/bed) was positively significant in physical health, environmental, social, overall domain and total score of QoL scores (P<0.05). The variable as BMI non-=obese women/control was negatively significant in social domain of QoL scores (P<0.05). Above the results, It suggests that the variable as BMI did't affect on the QoL in patients and control, but the variables as education and health perception affected on the QoL scores. Further study is required to conduct QoL differences between before and after treatment of obese patients.

배경: 세포 내 공간에서 가장 흔한 양이온은 칼륨이며 생리적으로 중요한 역할을 한다. 칼륨 불균형 발생시 생명을 위협할 수 있는 문제가 생길 수 있으며 그 문제들은 전신 쇠약부터 심실 세동에 의한 심장마비까지 있다. 따라서 응급의학과 의사가 짧은 시간 내에 그런 문제를 찾아내야 하는 것은 매우 중요하다. 이 연구에서 우리는 전혈과 혈청의 샘플들을 서로 짝을 지어 비교 분석하여 전혈의 결과가 혈청의 결과만큼 유용하게 쓰일 수 있는지 알아보기로 했다. 방법: 227명의 환자에게서 두 종류의 샘플을 채취하여 비교했다. 하나의 샘플은 요골동맥에서 채취한 전혈을 헤파린 처리된 주사기에 담아 검사했으며 다른 하나는 혈청 샘플을 담아 검사실에서 검사했다. 그 후 샘플들을 정상, 저 칼륨, 고 칼륨의 세 그룹으로 나누어 각각의 그룹에서 혈청과 전혈의 샘플들을 비교하였다. 결과: 혈청과 전혈의 칼륨 수치들의 차이는 통계학적으로 큰 의미를 보이지는 않았으며(P<0.05) 세 그룹 내에서의 칼륨 수치들간의 연관성은 통계학적으로 의미 있게 상관관계를 보였다(P<0.05). 세 그룹 중 고 칼륨 그룹에서 전혈과 혈청의 칼륨 수치가 가장 높은 상관관계를 보였으며 저 칼륨 그룹에서 가장 낮은 상관관계를 보였다. 결론: 전혈을 이용한 응급 검사가 칼륨 이상 소견, 특히 고칼륨혈증이 의심되는 환자의 진단에 선별검사로써 유용하게 사용될 수 있을 것으로 사료된다.

This study was aimed to reveal that the usual cold or heat state was associated with hypertension and could be a risk. We emailed educational personnel in D university to join this study and 182 subjects participated in from March to December in 2016. The usual cold or heat diagnosis was conducted by two experts who had over 10 years expertise. The blood pressure was measured from the subjected after 10 minute rest with Jawon medical device. The hypertension was diagnosed by the guide of the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. The frequency analysis was used in general characteristics, Pearson's Correlation Coefficient analysis was conducted in among continuous variables, and chi-square test was also used between hypertension and cold or heat group. Logistic regression was analyzed to generate the odds ratios (ORs) and 95% confidence interval (CI) for hypertension. The cold score was suggested to have negative association with Body mass Index (BMI, -.374, p<.001), systolic blood pressure (-.333, p<.001), and diastolic pressure (-.261, p<.001). The heat score was analyzed to have positive association with Body mass Index (.413, p<.001), systolic blood pressure (.249, p<.001), and diastolic pressure (.156, p<.001). The distribution of the cold group (35.1%) and non-cold group (64.9%) in hypertension was significantly different (p=0.18). The distribution of the heat group (62.2%) and non-heat group (37.8%) was significantly different (p=0.27). The usual cold was associated with decreased ORs (ORs 0.405, 95% CI=0.191-0.857), and usual heat was associated with increased ORs (ORs 2.327, 95% CI=1.108-4.888). However, after adjusting body mass index, sex, and smoking, the association was not significantly different. It is possible that usual cold or heat associate with hypertension. Further study is needed to show that usual heat may be a independent risk factor for hypertension through follow up design.

An immunoassay may be defined as an analytical procedure involving the competitive reaction between a limiting concentration of specific antibody and two populations of antigen, one of which is labelled or immobillized. The advent of immunoassay has revolutionised our knowledge of reproductive physiology and the practice of veterinary and clinical medicine. Radioimmunoassay (RIA) was the first of these methods to be developed, which meausred the analyte with good sensitivity, accuracy and precision (1,2). The essential components of RIA are:-(i) a limited concentration of antibodies, (ii) a reference preparation, and (iii) an antigen labelled with a radioisotope (usually tritium or iodine-125). Most procedures invelove isolating the antibody-bound fraction and measuring the amount of labelled antigen. Good facilities are available for scintilltion counting, data reduction nd statistical analysis. RIA is undergoing refinement through:-(i) the introduction of new techniques to separate the antibody-bound and free fractions which minimize the misclassification of labelled antigen into these compartments, and the amount of non-specfic binding. (3), (ii) the development of non-extration for the measurement of haptens (4), (iii) the determination of a, pp.rent free (i.e. non-protein bound) analytes (5), and (iv) the use of monoclonal antibodies(6). In 1968, Miles and Hales introduced in important new type of immunoassay which they termed immunora-diometric assay (IRMA) based on t도 use of isotopically labelled specific antibodies(7) in a move from limited to excess reagent systems. The concept of two-site IRMAs (with a capture antibody on a solid-phase, and a second labelled antibody to a different antigenic determinant of the analyte) has enabled the development of more sensitive and less-time consuming methods for the measurement of protein hormones ovar wide concentration of analyte (8). The increasing use of isotopic methos for diverse a, pp.ications has exposed several problems. For example, the radioactive half-life and radiolysis of the labelled reagent limits assay sensitivity and imposes a time limit on the usefulness of a kit. In addition, the potential health hazards associated with the use and disposal of radioactive cmpounds and the solvents and photofluors necessary for liquid scientillation counting are incompatable with the development of extra-laboratory tests. To date, the most practical alternative labels to radioisotopes, for the measurement of analytes in a concentration > 1 ng/ml, are erythrocytes, polystyrene particiles, gold sols, dyes and enzymes or cofactors with a visual or colorimetric end-point(9). Increased sensitivity to<1 pg/ml may be obtained with fluorescent and chemiluminescent labels, or enzymes with a fluorometric, chemiluminometric or bioluminometric end-point. The sensitivity of any immunoassay or immunometric assay depends on the affinity of the antibody-antigen reaction, the specific activity of the label, the precision with which the reagents are manipulated and the nonspecific background signal (10). The sensitivity of a limited reagent system for the measurement of haptens or proteins is mainly dependent upon the affinity of the antibodies and the smalleest amount of reagent that may be manipulated. Consequently, it is difficult in practice to improve on the sensitivity obtained with iodine-125 as the label. Conversely, with excess reagent systems for the measurement of proteins it is theoretically possible to increase assay sensitivity at least 1000 fold with alternative luminescent labels. To date, a 10-fold improvement has been achieved, and attempts are being made to reduce the influence of other variables on the specific signal from the immunoreaction.

Purpose: In patients with glufosinate poisoning, severe neurological symptoms may be closely related to a poor prognosis, but their appearance may be delayed. Therefore, this study aimed to determine whether the Acute Physiology and Chronic Health Evaluation II (APACHE II) score could predict the neurological prognosis in patients with glufosinate poisoning who present to the emergency room with alert mental status. Methods: This study was conducted retrospectively through a chart review for patients over 18 years who presented to a single emergency medical center from January 2018 to December 2022 due to glufosinate poisoning. Patients were divided into groups with a good neurological prognosis (Cerebral Performance Category [CPC] Scale 1 or 2) and a poor prognosis (CPC Scale 3, 4, or 5) to identify whether any variables showed significant differences between the two groups. Results: There were 66 patients (67.3%) with good neurological prognoses and 32 (32.8%) with poor prognoses. In the multivariate logistic analysis, the APACHE II score, serum amylase, and co-ingestion of alcohol showed significant results, with odds ratios of 1.387 (95% confidence interval [CI], 1.027-1.844), 1.017 (95% CI, 1.002-1.032), and 0.196 (95% CI, 0.040-0.948), respectively. With an APACHE II score cutoff of 6.5, the AUC was 0.826 (95% CI, 0.746-0.912). The cutoff of serum amylase was 75.5 U/L, with an AUC was 0.761 (95% CI, 0.652-0.844), and the AUC of no co-ingestion with alcohol was 0.629 (95% CI, 0.527-0.722). Conclusion: The APACHE II score could be a useful indicator for predicting the neurological prognosis of patients with glufosinate poisoning who have alert mental status.

배경: 양방향성 상대정맥-폐동맥 단락술은 복잡심기형의 일차적 고식수술 중 하나로, 여러가지 장점이 있으나 유아 환아들에서는 수술 후 위험성이 높은 것으로 알려져 있다. 대상 및 방법: 1995년부터 2003년까지 48명의 1세 이하 환아들이 연세대학교 심장혈관병원에서 양방향성 상대정맥-폐동맥 단락술을 시행 받았다. 모든 환아들은 단심실로 인한 폰탄수술의 대상자였다. 환아들은 수술당시의 나이에 따라 두 군으로 분류되었다 A군(<3개월, 12명)과 B군(3${\~}$12개월, 36명) 간에 평균 나이(67.58$\pm$3.78 vs. 212.91 $\pm$ 13.44일)와 평균 몸무게(4.51 $\pm$0.29 vs. 6.62 $\pm$0.27 kg)를 제외한 술 전 변수들은 차이가 없었다. 결과: A군에서 연속적으로 측정한 동맥혈 산소 포화도가 통계학적으로 유의하게 낮게 나타났다. 병원 내 사망률은 각각 $25\%$와 $19\%$였다. 추적관찰 기간동안 A군에서 2명, B군에서 5명의 만기 사망이 있었다. 결론: 본 연구에서는 유아기의 환아들에서도, 수술 위험성이 나이가 든 환아들과 비교하여 비슷하여 양방향성 상대정맥-폐동맥 단락술이 후에 시행될 폰탄수술의 위험성을 높일 수 있는 반복적인 고식적 수술을 피할 수 있는 수술방법이라고 생각한다. 하지만, 폐동맥고혈압이나 Heterotaxia 증후군 등이 동반된 고위험군 환아에서는 다른 고식적 수술을 고려하는 것이 좋을 것으로 생각한다.
