The purpose of this study is to compare the level of health-related quality of life and relating factor between institutional elderly and community living elderly. The subjects were 390 from Sanatorium or Nursing home and 467 from the community in Kwangju. The results are followed : 1) A comparison of ADL between two groups, institutional elderly and community living elderly, resulted in that community elderly were more significantly independent in the areas of bathing and transfer than institutional elderly. 2) A comparison of IADL between two groups resulted in that : Community elderly were more independent in the areas of using telephone and transportation, food preparation, house keeping, and doing laundry. Institutional elderly were more independent in the area of handling finances. 3) In the case of poor health-related quality of life, institutional elderly showed 2.4 times in the dimension of physical fitness, 1.8 times in daily activity, 2 times in social activity, 2 times in pain, 26.7 times in social support, and 0.4 times in subjective quality of life higher than community elderly There was no significant differences in the rest of dimensions. 4) In institutional elderly, the analysis of variables related to the health-related quality of life resulted in that; The relating factors were sex, education, and chronic illness in the dimension of physical function. Direct contact with family or significant others in the dimension of social activity. Chronic illness in the dimension of pain and perceived health status. Direct or indirect contact with family or significant others over the phone or through letters in the dimension of social support. 5) The analysis of variables related to the health-related quality of life showed that community elderly has more relating variables in each area than institutional elderly. The relating factors were age, sex, and chronic illness in the dimension of physical function. Education and chronic illness in the dimension of emotional status. Age and chronic illness in the dimension of daily activity and social activity Education and chronic illness in the dimension of pain and perceived health status. Sex, education, family size in the dimension of social support. Education and chronic illness in the dimension of subjective quality-of-life. Throughout general daily activity, community elderly showed more satisfactory results than institutional elderly, but in the subjective area of health-related quality of life, such as subjective quality of life, institutional elderly group showed more positive results. And community elderly had more relating factors than institutional elderly. For the health care of the elderly that focused on quality of life, new approaches considering the characteristics of both group, institutional and community living elderly, are needed.

In this study, we like to examine whether Panax ginseng water extract (PGWE) exerts antidiabetic activities in prevention and treatment modes in multiple low dose (MLD) streptozotocin (STZ) (20 mg/kg i.p injection for 5 days) induced diabetic SD rats. In the prevention mode, 150 mg/kg of GRWE was administered intraperitoneally with STZ for 3 weeks, and this group is called CO150. In the treatment mode, we started to administer the same dose of PGWE on day 8 and for 3 weeks, and this group is called POST150. PGWE exerted significant hypoglycemic activities in both prevention (normal control, 97±6 mg/dl; diabetic control, 331±23; CO150, 211±37) and treatment groups (normal control,128±4 mg/dl; diabetic control, 392±33; POST150, 263±44). Of great importance is the fact that plasma insulin levels in both groups were markedly increased as compared to the diabetic control (normal control, 428.7±62.1 pg/dl; diabetic control, 167.0±91.7; CO150, 377.6±68.7 in prevention mode, and in treatment mode normal control 417.9±<br/> 84.6 pg/dl; diabetic control, 166.1±104.7; POST150, 315.2±47.4). Blood glucose levels were closely associated with plasma insulin levels, and this result may suggest that PGWE showed the activity to enhance insulin secretion as well as preventing destruction of pancreatic islet cells. Food and water intakes were also determined at the last week of treatment in both groups. Characteristic symptoms of diabetes were significantly improved in both groups. In the prevention mode, water intake (ml/rat/day) in normal control was increased from 30.6±1.5 to 122.2±3.4 in diabetic control rats. In the CO150-treated group, water intake was dramatically reduced to 68.3±4.4 (p<0.001 vs. diabetic control). In the treatment mode, POST-treated group also reduced the water intake from 128.9±2.2 to 113.3±1.7. Taken together, our data suggest<br/> that PGWE showed comparable antidiabetic activities in prevention and treatment modes. Therefore, PGWE may have a potential as a prophylactic as well as therapeutic agent for type 2 diabetes mellitus (T2DM).

Pyoderma gangrenosum may be associated with underlying systemic diseases. The most frequently associated condition is inflammatory bowel disease. Other associations include chronic active and chronic persistent hepatitis, rheumatoid arthritis, leukemia, myeloma, ployarthritis, monoclonal gammopathy, myeloproliferative disorders, systemic lupus erythromatosus and Behcet`s disease. Multiple extensive pyoderma gangrenosum associated with Behcet`s disease has rarely been reported in Korea. Thus, we report a case of multiple pyoderma gangrenosums occurring as pathergy phenomenon at intravenous and intramuscular injection sites in a patient with Behcet`s disease.

Bacterial leaf spot, caused by Pseudomonas syringae pv. syrinage, is a very damaging disease to green pumpkin in Gong-ju and Non-san nursery. However, there is no good method to control the disease in Korea. Growth inhibition of pathogen on medium, control efficacy on seedling stage, and seed treatment effect of 6 anti-bacterial pesticides were investigated for selection of the best pesticide for seed treatment and control of the disease. Growth inhibition zone on King’s B medium were the largest by oxytetracycline 170 ppm and oxytetracycline 15 ppm + streptomycin sulfate 188 ppm, oxolinic acid 200 ppm, streptomycin 200 ppm were next respectively. Control efficacy of oxytetracycline 1.5% + streptomycin sulfate 18.8% WP and oxytetracycline 17% WP on seedling stage were 71.4% and 49.4%, respectively. Seed treatment of oxytetracycline 15 ppm + streptomycin sulfate 188 ppm on the artificially inoculated seeds inhibits pathogen growth completely from the treated seeds and 96% control efficacy on grow-out test of the treated seeds. Seed treatment of streptomycin 100 ppm (2,000 dilution of streptomycin 20%) on the artificially inoculated seeds allow 280 cfu/g of pathogen growth from the treated seeds and 60% control efficacy on grow-out test of the treated seeds. Seed treatment of oxytetracycline 85 ppm (2000 dilution of oxytetracycline 17% WP) on the artificially inoculated seeds allow 80 cfu/g of pathogen growth from the treated seeds and 90% control efficacy on grow-out test of the treated seeds. These results suggested that oxytetracycline 1.5% + streptomycin sulfate 18.8% WP was the best pesticide for seed treatment to control of the bacterial spot disease by Pseudomonas syringae pv. syringae.

This study was designed to compare the antidiabetic activities between Ginseng Radix Alba (GRA), Ginseng Radix Rubra (GRR) and Panax Quinquefoli Radix (PQR) in multiple low dose (MLD) streptozotocin (STZ) (20 mg/kg i.p injection for 5 days) induced diabetic rats. In the glucose tolerance test, 500 mg/kg of each ginseng ethanol extract was administered intraperitoneally 30 min before glucose challenge. While GRA failed to lower blood glucose level, GRR and PQR both significantly prevented the hyperglycemia when compared with the control group. In the MLD STZ-induced<br/> diabetic rats, 300 mg/kg of each ginseng ethanol extract was administered intraperitoneally for 2 weeks. Plasma glucose<br/> and insulin levels were markedly improved in all treatment groups. While GRR showed the highest antidiabetic activity, and GRA and PQR revealed somewhat equipotent antidiabetic activities, but less than that in GRR-treated group as far as blood parameters and diabetic symptoms such as polyphagia and polydipsia are concerned. Blood glucose levels were closely associated with plasma insulin levels, and this result may suggest that ginseng ethanol extracts showed the activity to enhance insulin secretion as well as preventing destruction of pancreatic islet cells. To elucidate the relationship between antidiabetic activity and ginsenoside profiles, seven major ginsenosides were quantified by HPLC. We figured out the fact that protopanaxatriol (PPT): proptopanaxadiol (PPD) ratio might play an important role in its hypoglycemia<br/> effects.

This study was performed to select potentially available biological control agent from soil bacteria for prevention of ginseng damping off. More than five hundred strains were isolated from ginseng rhizosphere soil. By testing antifungal activity, we have selected three soil bacteria strains and their ability to produce antibiotics and lytic enzymes such as cellulase, protease and pectate lyase was examined. Also, the presence of genes for biosynthesis of lipopeptide such as fengycin, bacillomycin D, surfactin, iturin A, and zwittermicin A was investigated in selected strains. All three strains produced cellulase, protease, and xylanase. Moreover, these strains had gene for biosynthesis of bacillomycin D, surfactin, and iturin A. ES1 and ES3 strains were identified Bacillus methylotrophucus and ES2 was confirmed Bacillus amyloliquefaciens using phylogenetic analysis on the basis of 16S rRNA gene sequences. In field test, control value of ES1, ES2 and ES3 treatment was 32.4%, 46.8% and 36.7%, respectively. This results indicate that antagonistic microbes with high ability of antifungal and lytic enzyme activity can be used as a useful biological control agent to control ginseng damping off.

This study was conducted to evaluate the accuracy of the official death registry in rural area. The base data used for the study was 379 deaths registered during the period of 1993 and 1994 in 4 rural townships of Chonnam province. The interview survey for cause-of-death was performed on the next of kin and/or neighbor. Additional medical informations were collected from hospitals and medical insurance associations for the purpose of verification. The underlying cause-of-death of 278 cases presumed by the survey was compared to the cause on official death registry. There was a prominent disagreement of cause-of-death between the survey data and the registry data(agreement rate: $38.9\sim44.6%$, according to disease classification method). These results may be caused by extremely low rates of physicians' certification, which were mostly confined to the poisoning and injury. Symptoms, signs, and ill defined conditions on death registry could be classified into circulatory disease(32.3%), neoplasm(21.2%), digestive disease(7.1%), injury and poisoning(7.1%) and so on. These results suggest that careful attention and verification be required on utilization of death registry data in rural area.

In other to study relationship of anxiety and serum cholesterol in general population, we performed the interview survey and screening test for the Ju-am cohort and residents in controlling area at 1995. Among them, 622 people are selected for this analysis. The results were summarized as follows. 1. Anxiety and total serum cholesterol related each other in the group of anxiety. Correlation coefficient was 0.39(p<0.01). 2. According to the result of multiple regression that the total serum cholesterol regarded as the dependent variable, anxiety and total serum cholesterol were related each other positively in the group of anxiety(p<0.05). 3. As the symptoms of anxiety was dichotomized affective and somatic symptom. There was no relationship of 2 symptoms and total serum cholesterol in all subjects, but there was more relationship on the affective symptom than on the somatic symptom in the group of anxiety(p<0.05). The above results show that anxiety and total serum cholesterol related each other significantly in the anxiety group. And the relationship of psychological factors and serum cholesterol could be applied significantly in general population as well as in the special group.

60세이상 노인인구를 대상으로 '농촌지역 노인들의 우울 및 인지기능 장애에 관한 연구'를 한 이정애와 정향균의 연구대상 558명에 대해 농촌지역 노인들의 인지기능 장애와 사망과의 관련성을 살펴본 결과는 다음과 같다. 1) 3년동안 동안 전체 대상자의 사망률은 558명중 57명인 10.2%이었으며 353명의 정상 인지기능군 중 사망자는 30명으로 사망률 8.5%, 126명 의 경도 인지장애군중 사망자는 14명으로 사망률 11.1%, 79명의 중증 인지장애군중 사망자는 13명으로 사망률 16.5% 이었다(표 3). 2) 3년동안 전체 연구 대상자의 생존율은 0.91이었으며 정상, 경도, 중증 인지기능 장애군의 3년 생존율은 각각 0.92, 0.90, 0.86이었다. 로그 순위 검정법으로 인지기능 정상군과 경도 및 중증의 각 인지기능 장애군의 생존곡선을 비교한 결과 통계적으로 유의하지 않았다. 또한 인지기능 정상군과 경도 이상의 인지기능 장애군간 생존곡선을 비교한 결과도 유의한 차이는 없었다. 3) 혼란변인을 보정하지 않는 Cox의 비례위험 회귀 모형의 단변량분석의 결과 95% 신뢰구간(C.I. : Confidence Interval)에서 사망위험도가 유의한 변인은 연령, 월수입, 흡연습관, 신체장애 등이었으며, 인지기능 장애정도를 정상 그리고 경도 및 중증으로 분류한 분석에서는 정상군에 비해 경도 및 중증의 사망위험도가 유의하게 높지 않았으나, 인지기능 점수(MMSEK score)의 증가에 따른 분석 결과 사망위험도가 0.94로 유의하게 낮게 나타났다(표 4). 4) 잠재적 혼란변인들의 영향을 보정한 Cox의 비례위험 회귀모형의 다변량 분석의 결과 인지기능 장애정도 및 MMSEK 점수증가에 따른 사망위험도는 어느 모형에서도 인지기능 장애정도가 사망에 미치는 위험도는 통계적으로 유의하지 않았다(표 5). 5) 남녀별로 각각 인지기능 장애와 사망위험도와의 관계를 알아보기 위해 다변량 분석을 시행한 결과 인지기능 장애정도 및 MMSEK 점수 증가에 따른 사망위험도는 어느 모형에서도 인지기능 장애정도가 사망에 미치는 위험도는 통계적으로 유의하지 않았다(표 6, 표 7). 이상 본 연구는 농촌지역 노인들에서 인지기능 장애정도가 사망에 미치는 영향을 알아보고자 하였지만, 인지기능 장애정도가 사망에 미치는 영향을 통계적으로 유의하게 고찰하지 못하였다. The purpose of this study was to examine the mortality risk associated with cognitive impairment among the rural elderly. The subjective of study was 558 of 'A Study on the Depression and Cognitive Impairment in the Rural Elderly' of Jung Ae Rhee and Hyang Gyun Jung's study(1993). Cognitive impairment and other social and health factors were assessed in 558 elderly rural community residents. For this study, a Korean version of the Mini-Mental State Examination(MMSEK) was used as a global indicator of cognitive functioning. And mortality risk factors for each cognitive impairment subgroup were identified by univariate and multivariate Cox regression analysis. At baseline 22.6% of the sample were mildly impaired and 14.2% were severely impaired. As the age increased, the cognitive function was more impaired. Sexual difference was existed in the cognitive function level. Also the variables such as smoking habits, physical disorders had the significant relationship with cognitive function impairment. Across a 3-year observation period the mortality rate was 8.5% for the cognitively unimpaired, 11.1% for the mildly impaired, and 16.5% for the severly impaired respendents. And the survival probability was .92 for the cognitively unimpaired, .90 for the mildly impaired, and .86 for the severly impaired respondents. Compared to survival curve for the cognitively unimpaired group, each survival curve for the mildly and the severely impaired group was not significantly different. When adjustments models were not made for the effects of other health and social covariates, each hazard ratio of death of mildly and severely impaired persons was not significantly different as compared with the cognitively unimpaired. But, as MMSEK score increased, significantly hazard ratio of death decreased. Employing Cox univariate proportional hazards model, statistically other significant variables were age, monthly income, smoking habits, physical disorders. Also when adjustments were made for the effects of other health and social covariates, there was no difference in hazard ratio of death between those with severe or mild impairment and unimpaired persons. And as MMSEK score increased, significantly hazard ratio of death did not decrease. Employing Cox multivariate proportional hazards model, statistically other significant variables were age, monthly income, physical disorders. Employing Cox multivariate proportional hazards model by sex, at men and women statistically significant variable was only age. For both men and women, also cognitive impairment was not a significant risk factor. Other investigators have found that cognitive impairment is a significant predictor of mortality. But we didn't find that it is a significant predictor of mortality. Even though the conclusions of our study were not related to cognitive impairment and mortality, early detection of impaired cognition and attention to associated health problems could improve the quality of life of these older adults and perhaps extend their survival.
