Purpose: This study was conducted to develop and to test the effects of an educational program for coping with problem situations as a nursing intervention in the diabetic patient. Method: A non-equivalent control group pretest-posttest design was used in this study. Data were collected from January to March, 2002. The subjects of the study consisted of 31 diabetic patients(experimental group : 17 patients, control group : 14 patients). The intervention of an educational program for coping with problem situations was applied to the experimental group for 4weeks(total 8 hours). Data were collected before the educational program, immediately after and 1 months later and were analyzed with repeated measures ANOVA, t-test, and paired t-test. Result: 1. There was a significant difference in self efficacy between the experimental and control groups (F=13.793, p=0.001). 2. There was a significant difference in self care behavior between the experimental and control groups (F=4.583, p=0.041). 3. There was a significant difference in coping behavior of the problem situation between the experimental and control groups (F=62.018, p=0.000). There was a significant difference according to experimental stages(F=4.546, p=0.015) and interaction between education and experimental stages(F=12.039, p=0.000). 4. There was a significant difference in glycemic control between the experimental and control groups (t=-3.112, p=0.004). Conclusion: These results support that a diabetic educational program for coping with problem situations is effective in promoting and maintaining self efficacy, self care behavior, problem coping behaviors and in improving glycemic control.

In this study. the importance of body fat distribution as an indicator of metabolic aberrations in diabetics was'evaluated. Skinfold thicknesses at eight sites and circumferences at five sites and total body fat content were measured on 105 diabetics. 1) The waist/thigh girth ratio(WTR) was positively correlated(r=0.38-0.54) to plasma glucose levels during oral glucose loading in diabetic men alone. 2) There was no significant difference in serum total cholesterol of diabetics and nondiabetics. However, HDL-cholesterol was significantly lower(p : 0.000. in male and female) in diabetics(male : 36.31$\pm$ 16.98mg/dl, female: 37.89$\pm$14.67mg/dl) than nodiabetics(male 61.75$\pm$14.08mg/dl, female : 62.29$\pm$12.65mg/dl) and serum triglyceride was significantly higher(p=0.0212) in diabetic women(171.90$\pm$ 76.61mg/dl) than nondiabetic women(111.10$\pm$42.84mg/dl) . 3) In both sexes. anthropometric measurements that significantly correlated to serum triglyceride concentration were percentage of ideal body weight. body mass index(BMI) and waist circumference. Positive and significant correlations were found between serum cholestrol, and BMI(R: 0.31, 0.34) and waist circumference(r=0.29) in diabetic men. Moreover, skinfolds of trunk area(r=0.29~0.32) especially abdomen, were closely associated with serum lipids than other fat deposits. Increasing percentage of total body fat content was accompanied by progressively increasing serum triglyceride concentration(r=0.41) in dieabetic men. This study shows that knowledge of body fat localization may help identify risks of carbohydrate intolerance and hyperlipidemia in diabetics.

Objective : This study was undertaken to investigate how Bombycis corpus (BC) effects the development and progress of complications occurring in Diabetes Mellitus (DM). Methods : Laboratory rats were seperated into three groups; normal, rats with DM and treated with BC, and rats with DM and not treated. In this study DM was experimentally induced through injection of streptozotocin. The BC treated group was given BC extract p.o. for 15 days. Then, The activities of glucose phosphatic enzymes and polyol pathway channels were observed. Results : The blood glucose level greatly increased in the DM groups after injection of streptoztocin, but it significantly decreased in the BC treated group. Significantly enhanced levels of serum insulin levels were seen in the BC treated group, while supressed levels were seen in the untreated DM group. Weight was recovered by the BC treated group, matching the normal group. Decreased enzyme activity of aldose reductase, sorbitol dehydrogenase and glucose-6-phosphatase were seen in BC treated diabetic rats. Increased enzyme activity, of the glucokinase and hexokinase were seen in BC treated diabetic rats. Conclusions : This study suggests that BC normalized the blood glucose and serum insulin levels destablized by DM. Because increased activity of glucose phosphatic enzymes, glucokinase and hexokinase, and decreased glucose-6-phosphatase activity, and suppression of polyol pathway enzymes, aldose reductase and sorbitol dehydrogenase, were all seen, these observations suggest that BC suppresses blood glucose levels and prevents complications due to DM.

수박의 형태적 변이의 유전적 원인을 분석해 보기 위해 8개 계통에서 re-sequencing을 수행하였다. 유전적 변이의 수는 염색체에 따라 다르게 나왔으며 발견된 SNP의 약 12.9%만이 유전자내에서 발견되었고 나머지는 프로모터나 유전자 사이의 지역에서 발견되었다. SNP 밀도에 대한 분석 결과 염색체 6번의 말단지역에 변이가 집중되어 있는 것을 알 수 있었다. 또한 염색체 10과 11번에 잘 보존된 지역을 발견하였다. Pathway 분석을 통해 DIMBOA(일종의 항생제)-glucoside 분해 대사가 계통간 가장 차이나는 것으로 확인되었으며 이는 각 계통의 병저항성에서 차이가날 가능성을 시사하는 것이다. 당대사 관련 유전자 변이를 분석한 결과 alpha-galactosidase 유전자에 가장 변이가 많은 것으로 밝혀졌다. 이러한 연구 결과는 육종을 분자수준에서 이해하는 데 도움을 줄 것으로 생각한다.
