This study was conducted to test the effect of a self regulation education program as a nursing intervention with chronically ill patients. A quasi experimental research(non equivalent control group pretest-posttest design) was used in this study. The subjects were 30 non insulin dependent diabetic patients(experimental group : 14 patients, control group : 16 patients). The study was carried out from May, 1995 to February, 1996. Data were collected before the education program, immediately after ＆ 2 menths later and were analyzed with repeated measure ANCOVA, paired t-test and t-test. The results are as follows : 1. There was a significant difference in self efficacy between the two groups（F＝27.61, P＝0.000）. There was a significant difference according to experimental stages（F＝33.09, P＝0.000） and interaction between education and experimental stages（F＝30.21, P＝0.000）. 2. There was a significant difference in self care behavior between the two groups（F＝27.05, P＝0. 000). There was a significant difference according to experimental stages（F＝31.14, P＝0.000） and interaction between education and experimental stages（F＝28.88, P＝0.000）. 3. There was a significant difference in glycemic control between before the education program and 2 months iater in the experimental group （t＝2.88, P＝0.013）. But there was no significant difference between before the education program and 2 months later in the control group. These results suggest that a self regulation education program is effective in promoting ＆ maintaining self care behavior and in improving glycemic control.. Thus this program can be recommended as an effective nursing intervention for chronically ill patients including diabetic patients.

To determine the frequency of past and present obesity among patients with NIDDM and to identify the differences of body fat, blood pressure and C-peptide/glucose ratio according to obese diabetic patients (BMI$\geq$25 kg/$m^2$) and nonobese (BMI<25 kg/$m^2$). Also the final factor is to observe the anthrometric change patterns in the study. Method: The weight at 20 years-old, previous maximal body weight, and acute weight loss were queried. Current height, body weight, BMI, waist & hip circumferences, waist-hip ratio, skinfold thicknesses, blood pressure, fasting blood glucose, and fasting C-peptide were measured in one hundred sixty-seven NIDDM patients. The differences of the parameters ccording to obese and nonobese, and three anthropometric change patterns were analyzed. Result: Results were as follows: 1. 66.5 % of the NIDDM patients had a history of past obesity as assessed by their maximum weight, while only 33.2% of them were currently obese (p's < 0.001). 2. The waist & hip circumferences, skinfold thicknesses, systolic, diastolic & mean arterial blood pressure in obese patients were greater than those of nonobese patients (all p's < 0.001). 3. The waist and the hip circumferences, and skinfold thicknesses (subscapula & triceps) were highest among the obese-obese group. WHR and abdominal skinfold thickness in the obese-obese and obese-nonobese groups were higher than those in the nonobese- nonobese group. Systolic & diastolic and mean arterial blood pressures in the obese-obese group were higher than those of obese-nonobese and nonobese-nonobese groups(all p's < 0.005). 4. The abdominal and subscapular skinfold thicknesses in female diabetic patients were greater than those of male patients (all p's <0.0001). Conclusion: Although most Korean NIDDM patients were previously obese, many of them were not obese during the course of the study. Greater central and upper body adiposicity and higher blood pressure was shown in obese diabetic patients. Also, greater central and upper body adiposicity was demonstrated in female diabetic patients.

The purpose of this study was to examine the effect of diabetes education on diabetic management by determining the changes of the knowledge and practice for diet therapy and blood glucose level pre-training and post-training. Statistical data analyses were completed using the SPSS 11.0 program. The results can be summarized as follows : The average age of the subjects was 52.8 years old, the period of suffering from diabetes was 7.9 years and 31% of the patients had a history of diabetes in their family members. In life style for self-management, they showed lower levels in drinking post-training, and significantly higher exercise levels post-training (P<0.05). Regarding the level of knowledge for diet, they showed significantly higher levels post-training in eight items such as importance of diet therapy for diabetes (p<0.005), principle of diet therapy (p<0.005), nutrient composition of foods (p<0.005), carbohydrate composition of foods (p<0.005), calorie prescribed to themselves (p<0.001), exchange units prescribed to themselves (p<0.005), exchange food items and exchanges units of cereal & grains (p<0.005) and exchange food items and exchanges units of fruit & juices (p<0.005). Regarding the practices of diet, they showed significantly higher levels of practice in keeping permitted meal size (p<0.005), using food exchange list (p<0.005), keeping exact meal times (p<0.001) and restricting most foods to eat (P<0.01) post-training. When measuring their bodies, average weight was lower post-training. Obesity was significantly lower post-training (p<0.01), and blood pressure both in systolic and diastolic was lower. Postcardinal-2hour blood glucose level decreased significantly from 268.4$\pm$98.9 pre-training to 180.9$\pm$48.4 post-training (p<0.001).

The increased occurrence of hyperglycemia and oxidative stress in streptozotocin (STZ) induced type I diabetes has been implicated in the etiology and pathology of disease complication. STZ has known to be genotoxic in a variety of assays including tests for microbial mutagenesis and unscheduled DNA synthesis in rat kidney. Diabetes mellitus (DM) is a pathologic condition, resulting in severe metabolic imbalances and non-physiologic changes in many tissues. We examined the effect of gamma radiation and KWNP on preventing the development of insulin dependent diabetes mellitus using streptozotocin-induced Fisher 344 diabetic rats. The hematological values (red blood cell and white blood cell), serum biochemical constituents-alkaline phosphatase (ALP), total cholesterol, triglycerides and insulin-were checked and the organs (testis, spleen and kidney) were weighed. The gonad indices of the STZ treated groups were much lower than the value of the control group. But the gonad indices of the KWNP treated groups were higher than those of the treated groups. The ratio of the weight of kidney to the body weight of the STZ treated groups was higher than that of the control group. The value of the diabetic group treated with KWNP after irradiation (F group) was lower than the other STZ treated groups. The white blood cell and ALP values of the F group were lower than the other STZ groups, as well. The cholesterol and triglyceride values of all the KWNP treated groups were significantly lower than the other groups. A significant increase (about 10 times) of insulin was detected in the F group. The results of hematological assay showed the distinctive damage in the irradiated and STZ treated groups. The quantity of apoptotic cells in seminiferous tubule of testis confirmed a serious damage as assessed in the STZ treated groups. These experimental results have revealed that treatment of the products of KWNP after irradiation has the antidiabetic effect in the STZ-induced diabetic rats. But the F group showed higher recuperative power. These experimental results have revealed that treatment of the gamma irradiation and KWNP have the recovering effect in the STZ-induced diabetic rats.

Impaired insulin secretion from pancreatic beta-cells in response to glucose is an important feature in the pathology of non-insulin-dependent diabetes mellitus (NIDDM). In the course of screening for useful insulin secretagogues, we have isolated and identified YHB-2017 (Genistein) as a insulin secretion potentiator from fermentation broths of our in-house microbial library. The insulinotropic activity of YHB-2017 in isolated rat pancreatic islets was exerted only at high concentration of glucose (8.3-16 mM) but not at low concentration of glucose (3.3-5.5 mM). Also, in perifusion study with isolated rat pancreatic islets, YHB-2017 stimulated insulin secretion in a time-dependent manner when YHB-2017 was added to KRB buffer containing 16 mM glucose. In the presence of $200\;{\mu}M$ diazoxide and 35 mM KCI, which stimulates maximum $Ca^{2+}$ influx independently of KATP channel, YHB-2017 enhanced KATP channel-independent insulin secretion at high concentration glucose (16 mM). To elucidate the mechanisms of the glucose-dependent potentiation effect of YHB-2017, pharmacologic inhibitors for protein kinase A, protein kinase C and calcium/calmodulin kinase II were pre-treated and then the potentiation effect of YHB-2017 on insulin secretion was investigated. Pre-treatment of H89 as a PKA inhibitor had a significant inhibitory effect on YHB-2017-induced potentiation effect. Furthermore, western immunoblotting analyses revealed that YHB-2017 increased phosphorylation of PKA substrates and cAMP response element-binding protein (CREB) under high concentration of glucose. These results demonstrated that the insulinotropic effect of YHB-2017 is mediated through PKA signal pathway and activated amplifying $K_{ATP}$ channel-independent insulin secretion pathway.

This study estimated the re!ation between psychological stress and stress hormones, nu­t tritional status of patients with non-insulin dependent diabetes mellitus(NIDDM). Psycho­l logical stress such as depr'ession and anxiety in 34 diabetics was analyzedin relation to nutrient intake, blood components such as fasting blood sugar(FBS), hemoglobin AIC, stress hormones a and amino acids. The IeveIs of depression and anxiety were measured by The center for ep­i idemiological studies-depc$pm$111.49pg/ml for total catecholamine ( (norepmephrine and epinephrine) and 233.95 $pm$73.99pg/ml for norepinephrine, 94.03$pm$75. 9 97pg/ml for epinephrine, 13.lS$pm$5.55pl/dl for cortisol and 171.50$pm$62.50pg/ml for gul c cagon respectlveIy. The leveIs of stress hormones in diabetics such as total catecholamine, norep­i mephrine cortisol and glucagon were significantly higher than those in normal control. The lev­el of epmephrine was higher in diabetics but the diffierenee was not significant. The calorie m t take in diabetics was 1762$pm$292keal which is S1.4% lower than Korean recommended dietary a allowances(RDA). Calcium intake was slightly low but other nutrients intakeswere higher than R RDA. The value of fasting blood sugar(FBS), usual fasting blood sugar(usual FBS) which refteet a average FBS during 3 months and hemoglobin Al C in diabetics was 1S4.1S$pm$74.22mg/dl, 177.76$pm$42.77mg/dl and S.S4$pm$2.S2% respec디VeIy. The distribution of plasma amino acids in d diabetics was generally in the normal range. The leveI of anxiety in diabetics was positively cor­related with norepinephrine, concentration and usual FBS. The levels of glucagon, usual FBS a and hemoglobin Aj C were pOSI디veIy correlated with the branched chaimamino acid(BCM : leucme, isoleucme and valine)

Purpose: This study was done to identify fat distribution and blood pressure according to anthropometric change patterns between NIDDM patients and control subjects. Methods: Cross-sectionally 167 NIDDM patients and 87 controls were studied. Previous maximal body weight and acute weight loss was obtained. Current height, body weight, BMI, waist-hip ratio(WHR), skinfold thicknesses(abdomen, subscapular & triceps), and blood pressure was measured. Three anthropometric change patterns were categorized by BMI changes from the maximum lifetim's BMI to the current time (obese-obese, obese-nonobese and nonobese-nonobese: obese: BMI$\geq$25kg/m$^2$, nonobese: BMI<25kg/m$^2$). The data was analyzed by $X^2$, t-test, age adjusted ANCOVA and Least Squares Means(LSM) for multiple comparison. Result: Acute body weight loss(p=0.01), anthropometric change types (p=0.001), WHR (p=0.05), and skinfold thickness (p=0.002) of NIDDM were significantly higher than those of the controls. The mean arterial pressure, WHR and skinfold thicknesses were greater in both obese-obese and obese-nonobese NIDDM and control subjects compared with both nonobese-nonobese NIDDM and control subjects. (all p's<0.05). Conclusion: NIDDM patients had more central and upper body adiposicity. Also both obese-obese and obese-nonobese NIDDM and control subjects had higher mean arterial pressures and central body obesity.

High risk of cardiovascular diseases caused by existing PPAR-${\gamma}$ agonists such as rosiglitazone and pioglitazone has been recently reported. CKD-501 is a novel selective PPAR-${\gamma}$ agonist as a potential target to reduce cardiovascular risk in non-insulin dependent diabetes mellitus (NIDDM). In this study, We investigated potential cardiotoxicity of CKD-501 and compared its toxicity with that of rosiglitazone or pioglitazone using db/db mice. After 12-week repeated administration of CKD-501 at doses of 3, 10 and 30 mg/kg/day or rosiglitazone at doses of 10 and 30 mg/kg/day or pioglitazone at doses of 200 and 540 mg/kg/day, animals were sacrificed for investigation of potential toxicities. Diameters of left ventricles and areas of cardiomyocytes were measured. And lipid accumulation and apoptosis in heart muscle were examined by oil red O staining and TUNEL staining, respectively. Diameters of left ventricles were significantly increased in high dose treatment group of pioglitazone compared to control (p<0.05), while other groups showed a tendency for an increase. All test articles induced significantly the increase of area of cardiomyocytes in heart compared to control (p<0.01), in regular order as pioglitazone > CKD-501 ${\geq}$ rosiglitazone. However, lipid accumulation and apoptotic changes in heart were not observed in all dosing groups. Taken together, the myocardial cell hypertrophy of CKD-501 are relatively lower than that of pioglitazone and similar to rosiglitazone. And it is suggested that the myocardial cell hypertrophy of CKD-501 are less adverse in clinical use for the management of the NIDDM.

Metformin is a treatment used widely for non-insulin-dependent diabetes mellitus with few side effects and acts by inhibiting hepatic gluconeogenesis and glucose absorption from the gastrointestinal tract. Lymphoma is one of the most common hematological malignancies in dogs. Chemotherapy is used mainly on lymphoma, but further research on developing anticancer drugs for lymphoma is needed because of its severe side effects. This study examined the anticancer effects of metformin alone and in combination with 2-deoxy-D-glucose (2-DG), a glucose analog, on EL4 cells (mouse T cell lymphoma). Metformin reduced the metabolic activity of EL4 cells and showed an additive effect when combined with 2-DG. In addition, cell death was confirmed using a trypan blue exclusion test, Hochest 33342/propidium iodide (PI) staining, and Annexin V/PI staining. An analysis of the cell cycle and mitochondria membrane potential (MMP) to investigate the mechanism of action showed that metformin stopped the G2/M phase of EL4 cells, and metformin + 2-DG decreased MMP. Metformin exhibited anticancer effects as a G2/M phase arrest mechanism in EL4 cells and showed additive effects when combined with 2-DG via MMP reduction. Unlike cytotoxic chemotherapeutic anticancer drugs, metformin and 2-DG are related to cellular glucose metabolism and have little toxicity. Therefore, metformin and 2-DG can be an alternative to reduce the toxicity caused by chemotherapeutic anticancer drugs. Nevertheless, research is needed to verify the in vivo efficacy of metformin and 2-DG before they can be used in lymphoma treatments.

Purpose: The uptake of $^{18}F$-FDG is often observed in normal cell of colon to patients who have non-insulin-dependent diabetes mellitus and had taken anti-diabetic drugs including Metformin in PET/CT scan. In this study, the region of colon was compared between the patients who took anti-diabetic drugs including Metfomin and other patients who took the other anti-diabetic drugs through SUV measurements. Materials and Methods: A hundred eighty patients were studied. 120 patients who have non-insulin-dependent diabetes mellitus (Including Metformin: 60, Excluding Metformin: 60) and 60 patients as a control group were composed. The patient fasted at least 6 hours before receiving an intravenous injection of 370-592 MBq (10-16 mCi) of $^{18}F$-FDG. Scanning from the base of the skull though the mid thigh was performed using the Discovery STe PET/CT Equipment (GE Healthcare, Milwaukee, WI, USA). The highest uptake region was measured SUV among ascending, transverse and descending colon. Results: The values of patients who took the anti-diabetic drugs including Metformin were $6.16{\pm}3.64$ g/mL, $4.41{\pm}2.94$ g/mL, and $5.46{\pm}2.44$ g/mL. The patients who took the anti-diabetic drugs which does not have Metformin were $3.05{\pm}1.39$ g/mL, $2.08{\pm}0.97$ g/mL and $3.15{\pm}1.85$ g/mL. The control group were $2.02{\pm}0.88$ g/mL, $1.68{\pm}0.87$ g/mL and $2.19{\pm}1.88$ g/mL. Conclusion: The effect of the intake of Metformin was observed from the SUV on region of large bowel in this study. Thus, it could be helpful for the results by identifying the ingredient of anti-diabetic drug before the examination and the possibility of interpretation of false positive will be reduced.
