  • 본 연구는 항산화 활성 및 항당뇨 효과가 있는 조각자 추출물인 GSM (methanol 추출물)과 GSE (ethanol 추출물)에 대한 연구이다. 추출 용매에 대한 페놀 함량을 측정한 결과 100 g 당 GSM에서는 1.12 g이며, GSE에서는 0.6 g으로 GSM에서 함량이 높은 것으로 나타났다. DPPH 라디칼 소거능의 경우 최대 농도 1,000 ${\mu}g$/ml에서 확인한 결과 GSM에서는 68.8% 그리고 GSE에서는 70.4%로 두 종류 추출물에서 높은 결과를 확인할 수 있었다. DNA 손상 정도를 확인한 comet assay에서도 200 ${\mu}M$ $H_2O_2$에 의해 나타나는 DNA 손상에 대하여 GSM과 GSE는 DNA를 보호하는 활성이 있었다. 항당뇨 효과를 알아보는 $\alpha$-glucosidase 억제 실험에서 GSM은 17.9%, GSE는 10.3%이었으며, 처리시간을 증가하였을 경우에는 그 억제 정도가 GSM의 경우 25%이며, GSE의 경우 20%로 증가하여 항당뇨 효과가 있다는 것을 확인할 수 있었다. 이 결과로부터 당뇨병 치료에 대한 새로운 소재로써 조각자 추출물의 가능성을 확인하였다.

  • 인삼은 건강에 효과적인 약초라고 알려져 왔다. 인삼의 열매인 진생베리는 인삼의 주성분과 비슷한 ginsenoside, saponin, polyphenol, polyacetylene, alkaloid 등의 성분을 포함한다. 본 연구의 목적은 인삼과 같이 진생베리 열수 추출물(Ginseng berry water extract, GBE)이 당뇨와 연관된 세포 외 효소와 인슐린 신호전달 경로에 있는 분자의 발현에 어떤 효과를 가지고 있는지를 조사하였다. ${\alpha}$-Amylase와 ${\alpha}$-glucosidase는 섭취한 다당분자를 분해하여 포도당을 생성함으로 항당뇨 약물개발의 표적 효소이다. GBE에 의한 두 효소의 활성 억제능을 in vitro에서 측정하였으나 최고 $1,000{\mu}g/ml$ 농도에서도 효소활성 억제능이 나타나지 않았다. 인슐린 신호전달 경로의 영향을 확인하기 위해서 HepG2 세포에서 GBE에 의한 인슐린 신호전달 경로의 주요 단백질인 protein-tyrosine phosphatase 1B (PTP1B)와 Akt1의 발현수준 변화를 Western blot 방법으로 조사하였다. 이때 인슐린에 의한 이들 분자의 변화에 GBE가 영향을 주는 것으로 나타났다. PTP1B는 인슐린에 의해 증가된 발현량이 저농도의 GBE이 의해 더욱 증가하였으나, $200{\mu}g/ml$ 농도의 GBE에 의해서는 다소 감소하는 것으로 나타났다. 또한, Akt1도 인슐린에 의해 증가된 발현량이 GBE 농도에 따라 감소하는 것으로 나타났다.

  • 활성산소란 세포에 손상을 가하는 모든 종류의 변형된 산소를 의미하며, 활성산소 생성의 증가는 세포 내의 산화적 스트레스를 유발하여 심혈관 질환, 암, 당뇨, 근위축 등 각종 질병의 원인이 된다. 그러나 적정 수준의 활성산소는 세포의 성장 및 발달에 중요한 역할을 담당하는 것으로 보고되어 있으며, 골격근에서의 활성산소는 근기능과 대사에 필수적인 역할을 담당한다. 규칙적인 운동은 건강상 다양한 이점을 가져다주지만, 과도한 운동은 골격근을 비롯한 다양한 체내 조직에서 활성산소의 생성을 증가시키며, 고농도의 활성산소 생성은 세포 손상을 일으키는 것으로 보고되고 있다. 따라서 운동에 의한 활성산소의 생성 증가와 그에 따른 분자적 기전은 운동이 주는 건강상의 많은 이점들을 이해하는데 있어 중요한 기전으로 받아들여지고 있다. 최근 운동 강도나 형태에 따른 활성산소의 생성 수준과 근육 관련 유전자 발현 및 대사 관련 연구에 있어 활성산소의 역할에 관한 연구들이 활발히 이루어지고 있지만 심도 있는 기전적 연구와 이해는 부족한 실정이다. 따라서 본 총설에서는 운동에 의한 활성산소 생성 기전과 그에 따른 역할에 대한 선행 연구들을 살펴보고, 운동에 의한 인슐린 신호체계의 활성 및 그에 따른 수명 조절에 있어 NADPH 산화효소의 역할에 대해서도 살펴보았다.

  • Objectives : To gather information about the factors which influence the interest and intention of admission into charging nursing hones for the elderly(CNH), as these homes represent an important method for resolving the problems related to the rapid population aging occurring in Korea. Methods : A face-to-face interview survey was carried out with 320(men 159, women 165) patients over 60 years old who were admitted at 2 university hospitals and 5 general hospitals in the Busan area between December 1998 and March 1999. Data were analyzed through t-test, ANOVA, correlation and multiple regression analysis. Results : The mean age and years of education of the study population was 67.0 and 7.7 years, and the types of chronic degenerative disease included musculoskeletal disorders(20.1%), cerebrovascular disease(17.1%), and diabetes(14.3%). The major forms of household living arrangement prior to admission were elderly alone(22.6%), and elderly couple(33.5%), while about half of them(55.5%) didn't want to live with their children id the future. Almost half were paying medication fees by themselves(46.6%). The level of actual intention of admission$(3.07{\pm}1.39)$ into a CNH was lower than that of interest$(3.22{\pm}1.33)$(p<0.01). Multiple analysis revealed that the intention of admission increased with decreasing number of future supportive persons$(\beta=-0.107)$, lower level of activity in daily life$(\beta=-0.447)$, and longer years of education$(\beta=-0.447)$ with 32.7% of $R^2$. As for the factors which determined the admission into a CNH, the fee and facilities were considered to be most important, and professional nursing and physician's care were the most desired services. In nomenclature, they preferred 'elderly hospital' or 'elderly health center' to CNH. Conclusions : Interest in CNH is increasing recently, but existing studies about patient experiences in CHN are still limited. This study may form a basis for future examinations of the needs and uses for CNH. Active financial support and public information are considered by the authors to be important factors for the induction of welfare services for the elderly, though CNH.

  • Objectives: The present study was undertaken to study the maternal risk factors for preterm birth (PTB) and low birth weight (LBW) with a special emphasis on assessing the proportions of maternal genitourinary and periodontal infections among Indian women and their association with adverse pregnancy outcomes. Methods: A hospital-based prospective study comprising 790 pregnant women visiting the obstetrics clinic for a routine antenatal check-up was undertaken. Once recruited, all study participants underwent clinical and microbiological investigations for genitourinary infections followed by a dental check-up for the presence of periodontitis. The study participants were followed up until their delivery to record the pregnancy outcomes. Infectious and non-infectious risk factors for PTB and LBW were assessed using univariate and multivariate Cox regression analysis. Independent risk factors for PTB and LBW were reported in terms of adjusted relative risk (ARR) with the 95% confidence interval (CI). Results: Rates of PTB and LBW in the study population were 7.6% and 11.4%, respectively. Previous preterm delivery (ARR, 5.37; 95% CI, 1.5 to 19.1), periodontitis (ARR, 2.39; 95% CI, 1.1 to 4.9), Oligohydramnios (ARR, 5.23; 95% CI, 2.4 to 11.5), presence of Nugent's intermediate vaginal flora (ARR, 2.75; 95% CI, 1.4 to 5.1), gestational diabetes mellitus (ARR, 2.91; 95% CI, 1.0 to 8.3), and maternal height <1.50 m (ARR, 2.21; 95% CI, 1.1 to 4.1) were risk factors for PTB, while periodontitis (ARR, 3.38; 95% CI, 1.6 to 6.9), gestational hypertension (ARR, 3.70; 95% CI, 1.3 to 10.8), maternal height <1.50 m (ARR, 2.66; 95% CI, 1.3 to 5.1) and genital infection during later stages of pregnancy (ARR, 2.79; 95% CI, 1.2 to 6.1) were independent risk factors for LBW. Conclusions: Our study findings underscore the need to consider screening for potential genitourinary and periodontal infections during routine antenatal care in developing countries.

  • This research was conducted to understand and analyze the health-related behaviors of middle school students and get fundamental research data essential to provide efficient student guidance and public health service at school. The interview using Youth Risk Behavior Surveillance System(YRBSS). Translation and modification for Korean students of the YRBS. The Korean version of YRBS(Youth Risk Behavior Surveillance System) that translation and modification for Korean students of the YRBS developed by the Centers for Disease Control and Prevention(CDC)was used to assessment to health-related behaviors of youth. The interviewees were 1040 enrolled students at middle school in Daegu metropolitan city. YRBSS monitors six categories of priority health behaviors among youth and young adults behaviors that contribute to unintentional and intentional injuries; tobacco use; alcohol and other drug use, sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases(STDs)(including human immunodeficiency virus infection); unhealthy dietary behaviors; and physical activity. The result shows that over 30% of students rarely or never used safety belt and almost students were rarely or never wore a bicycle helmet. During the 12 months preceding the survey, 21.9% female students had felt so sad or hopeless almost every day for $\geq$ 2weeks in a row that they stopped doing some usually activities 20.5% of male middle school students have ever tried cigarette smoking. 26.2% of male students and 27.2% do female students had had over one drinks of alcohol during their lifetime(lifetime alcohol use). 47% of male students had had over one drinks of alcohol on $\geq$ 1 of the 30 days preceding the survey(current alcohol use). Over one half of female student were thought they were overweight. These results suggest that some risk behaviors be very prevalent in a korean middle school students and priority health-risk behaviors, which contribute to the leading cause of mortality and morbidity among youth and adult, often are establish during middle school age, extend into adulthood, are interrelated. Among both children and adults, the leading causes of death are closely linked to these behaviors. Among adults, chronic diseases such as cardiovascular disease, cancer, and diabetes are the national leading killers. Practicing healthy behaviors, such as eating low-fat, high-fruit-and-vegetable diets, getting regular physical activity, and refraining from tobacco use, would prevent many premature deaths. Because health-related behaviors are usually established in childhood, positive choices need to be promoted before damaging behaviors are initiated or become ingrained.

  • Hypercholesterolemia is one of main causes of coronary heart disease(CHD). Clinical trials demonstrated that lowering serum cholesterol levels would reduce incidence of new cardiovascular events and mortality by primary or secondary preventions. The objective of this retrospective study was to compare efficacy and side effects of lovartatin and simvastatin in treatement of hypercholesterolemia. In Boramae Hospital, patients were included when they have taken lovastatin 20 mg or simvastatin 10 mg for 52 weeks with laboratory monitoring for cholesterol at baseline, 3, 6 and 12 month period. As results, total 128 outpatients were included with their total cholesterol level <240 mg/dl and triglyceride level <400 mg/dl at baseline. Total cholesterol and LDL cholesterol of lovastatin group (n=60) and simvastatin group (n=68) were significantly reduced from baseline (p=0.001). Lovastatin maximally reduced total cholesterol by $23.9\%,\;triglyceride\;by\;12.3\%$, LDL cholesterol by $36.1\;\%$ and increased HDL cholerterol by $7.8\%$ and simvastatin reduced by $24.1\%,\;20.5\%,\;34.3\%\;respectively$ and HDL increased by $11.2\%$. There were no significant differences between lovastatin and simvastatin in mean percent change of lipid levels at 12, 24 and 52 weeks from baseline. Cumulative percentage of patients reaching the target LDL cholesterol concentration by 24 weeks was $61.7\%$ in lovastatin and $64.7\%$ in simvastatin. Average time to reach the target LDL goal was 100.1 days in lovastatin and 99.8 days in simvastatin. Both lovastatin and simvastatin also significantly reduced total cholesterol and LDL cholesterol in all subgroups (diabetes mellitus, hypertension, and coronary heart disease). In this study, treatment efficacy in patients with coronary heart disease was lower than other patients. Considering clinical importance of secondary prevention, more intensive treatment is necessary to decrease LDL cholesterol level of 100 mg/dl or lower in patients with coronary heart disease or other clinical atherosclerotic disease. There were no serious side effects during the study period. Digestive side effects were most frequently reported (lovastatin $8.3\%\;vs\;simvastatin\;8.8\%$). In conclusion, both lovastatin and simvastatin were similar in lipid lowering effects and there was no difference in incidence of side effects.

  • This study focused on the properties natural dyeing and natural material and on the development of functional material for well-being in apparel industry. Comus officinalis Siebold et Zuccarini is used as natural dyeing material which had been reported that have curable effect for unbalanced immunity, geriatric diseases like urinary tract system, diabetes, hypertension, arthritis, tinnitus, hyperhidrosis and women's diseases like hypermenorrhea. And this material also has anti-cancer effect so that can restraint cancer cells. 3 kinds tester of cotton, wool and silk are dyed by boiled with each dye (flower, fruits, bark of tree) as first dyeing and dried in the shade. These testers are done by post-mordanting method. Aluminium Potassium(Alk(SO4)2), Cuprie Sulfate($CuSO4{\cdot}5H2O$), Stannous Chloride($SnCl2{\cdot}2H2O$), Ferrous Sulfate($FeCl2{\cdot}4H2O$), Titanium Sulfate 24% aqueous solution(Ti(SO4)2) are used as mordants. Dyeing results of Comus officinalis Siebold et Zuccarini flower and bark are shown as yellow color series. And dyeing result of fruits is pink color series. Silk shows the best dyeing property. As the point of view for dyeing property, Ti, Sn, Fe would be the properchoice for mordant. Following results are extracted in this study. Yellow color is resulted in dyeing with Cornus officinalis flower as non-mordanting condition. Yellowish red color is come from dyeing with Comus officinalis fruit as non-mordanting condition. Grayish yellow tone is resulted in dyeing with bark as non-mordanting condition. Orange tone color with Ti-mordanting, green tone color with Sn-mordanting and gray tone color with Fe-mordanting is resulted respectively. However light-fastness of Comus officinalis(flower, fruit, bark) is very low as 1 or 2 level in non-mordanting condition, Comus officinalis flower dyeing is turned out 3 or 4 level and fruit dyeing is 4 or 5 level, bark dyeing is 2 or 3 level with Ti-mordanting respectively. Eventually Comus officinalis fruit has the best light-colorfastness property among all of dyes. dry cleaning colorfastness of Cornus officinalis(flower, fruit, bark) is good as 4 or 5 level in Ti-mordanting condition, perspiration-colorfastness of Cornus officinalis(flower, fruit, bark) is good as 4 or 5 level in Ti-mordanting condition, With these results, this study could conclude that dye-ability, colorfastness problem is getting better after mordanting process and practical usage would be possible.
