These days, citizens have made change of food life to take Western style food and to suffer from diabetes because of excessive nutrition taking, less exercise, stress and other environmental factors. They may suffer from diabetes because of genetic defect, surgery of pancreas, disinfection and medicine and others. One of ten Koreans may have symptom of diabetes to be popular. The diabetes that is a kind of metabolic disease has high blood sugar at disorder of hyper insulinism and/or defect of insulin action. Long time high blood sugar may produce chronic disease of kidney, eyes, nerve, heart and blood vessel and others. The purpose of health care of diabetes patient was to reach target blood sugar by diet, physical exercise and medicine and to prevent and delay complication. Diabetes patient shall control blood sugar to keep healthy. The blood sugar control requires time and effort, and all of the patients are difficult to make effort and to spend time. You can control blood sugar by the application. The application allows patients to control blood sugar and to save time and efforts and to make small sized input and automation of remaining area. The service was limited to blood sugar graph, and user carries smart phone to conduct test and to have difficulty. Further study needs to solve the problems and to investigate blood sugar testing not carrying smart phone and to make application of easy control of blood sugar.

Fish oil and shortening have been suggested to have opposite effects on cardiovascular disease (CVD). This study investigated the effect of shortening and fish oil on CVD risk factors and aorta histopathology, and the association between risk factors and aorta histopathology. Male Wister rats (n=30) were fed an AIN-93G diet containing 20% fat in the form of fish oil, shortening, or soybean oil for 4 weeks. Total cholesterol (TC), triacylglyceride (TG), and C-reactive protein levels were significantly (P<0.001) lower in the fish oil than in soybean oil and shortening groups. HDL-cholesterol concentrations were significantly different (P<0.001) between groups. In addition, LDL-cholesterol levels were significantly (P<0.001) lower in the fish oil and shortening groups than in the soybean oil group. Insulin and glucose concentrations did not differ among groups. Effect of dietary fat on tissue fatty acid composition significantly differed in abdominal fat and brain compared with RBC, heart, kidney and liver. The aortic wall was significantly (P=0.02) thinner in the fish oil group than in the soybean oil and shortening groups. The aortic wall thickness was positively correlated with TG and TC, but negatively with EPA + DHA levels of all tissues. These results suggested that fish oil had protective effects on aorta histopathology by hypolipidemic action in this rat model.

This study was evaluated the metabolic, physiologic and histologic effects of myocardial protection of verapamil[isoveratril]on isolated rat hearts to 90 minutes of ischemic arrest. Heart was perfused with a modified Kreb’s Henseleit bicarbonate buffer with glucose and arrested with retrograde coronary perfusion by glucose insulin[GI], potassium and verapamil. Mean aortic systolic pressure, heart rate, coronary flows were measured and morphologic changes were examined during working heart perfusion. Perfusion and arrest were controlled four groups subjected 60 isolated rat hearts. Four groups hearts reperfused during 40 minutes after 90 minutes global ischemia for physiologic recovery. 15 hearts of four groups were assayed to histological morphologic changes. GI treated hearts recovered less than 28% of function and changed more than 80% of mitochondria of control group. Verapamil hearts[0.2, 0.1 gm/kg] recovered more than 88% of function and permitted the maintenance of continuous cellular level of Serum Glutamic Oxalaxetate Transaminase[SGOT], but declined 28% of Phosphate Kinase[CP], GI treated heart showed widespread evidence of extensive damage of mitochondria. The damage was that interstitial huge edema are present and there was contraction band formation within the swollen cells. The verapamil and potassium group were not found morphologic change compared with control group. Their functions were shown that metabolic and physiologic action of verapamil-group lasted 20 minutes longer than potassium group.

The purpose of this study to compare of clinical profile between obese and nonobese type 2 diabetic patients. The subjects were consist of 111 obese (50 male, 61 female) and 159 non obese (79 male, 80 female) type 2 diabetic patients underwent fasting blood glucose, 2-hour postprandial blood glucose, $HbA_1c$, total cholesterol, triglyceride, high density lipoprotein, microalbuminuria, fasting C-peptide and 2-hour postprandial C-peptide were measured. Diabetes was diagnosed according to the American Diabetes Association (ADA) criteria. Obesity was defined as body mass index (BMI, kilograms per meters squared) ${\geq}23$. Data analyses were t-test, chisquare test in SAS program. The results were as follows : 1) Triglycerides and 2-hour postprandial C-peptide were significant higher in obese than non-obese patients. 2) Systolic blood pressure, Diastolic blood pressure, fasting blood sugar, 2-hour postprandial blood glucose, $HbA_1c$, total cholesterol, high-density lipoprotein, microalbuminuria and fasting C-peptide were no difference between obese and non-obese groups. These data indicate that obesity is a risk factor for the development of coronary heart disease (CHD) in diabetic patients. Therefore, weight reductions have beneficial effects on insulin action and glycemic control in obese type 2 diabetic patients.

The present study was carried out to investigate the preventive effect of Epimedii Herba combined Samgijiwhang-Tang(SJTE) on streptozotocin(STZ)-induced diabetic nephropathy. SJTE was given to rats with oral administration. The experimental animals were divided into normal group of rats, control group of STZ-induced diabetic rats, and sample group with SJTE administration. Experimental diabetic nephropathy was induced by the injection of STZ(60mg/kg) to the rat via the peritoneum. The effect of SJTE on STZ-induced diabetic nephropathy was observed by measuring the serum level of insulin, glucose, creatinine and BUN. Urine secretion of albumin for 24 hours and urine level of glucose measures too. Anti-oxidative stress of STZ administration in living body was estimated by measuring lipid peroxide in cortex of kidneys. STZ induced increase of serum glucose. creatinine, urine albumin secretion and renal cortical lipid peroxidation were lowered by SJTE administration. In conclusion, the SJTE treatment showed protective effect on rat diabolic nephropathy model, and action mechanism of the effect was thought to be concerned with internal glucose metabolism.

Tectorigenin has an apoptosis-inducing ability and immunosuppressive activity. We investigated the effect of tectorigenin on Phase I and II enzyme activities to elucidate the pharmacological action of the immunosuppressive tectorigenin in the diabetic rat. This compound was obtained from the hydrolysis of tetoridin isolated from the flower of Pueraria thumbergiana (Leguminosae). This crude drug (Puerariae Flos) has been used as a therapeutic for diabetes mellitus in traditional Korean medicine. Tecotrigenin inhibited the formation of malondialdehyde (MDA) and hydroxy radicals in serum and liver but promoted superoxide dismutase (SOD) activity. Low MDA contents and low xanthine oxidase and aldehyde oxidase activities were observed in the tectorigenin-treated rats, suggesting that such Phase I enzyme activities are the major source of lipid peroxidation. However, tectorigenin increased Phase II enzyme activities such as SOD, glutathione peroxidase and catalase, suggesting the activation of free radical-scavenging enzymes. The activities of tectorigenin were comparable to those of glibenclamide, which was employed as a positive control. These results suggest that tectorigenin may share some biological properties with glibenclamide in insulin-dependent-diabetes mellitus (IDDM).

Objectives : Coptidis rhizoma (CR) is an oriental medicine that has been used in many traditional prescriptions against diabetes mellitus in Korea for centuries. Our purpose was to determine the protective effect and its action mechanism of CR on the cytotoxicity of pancreatic -cell line (RINm5F cell). Methods : In this experiment, we used methods such as MTT assay for detection of cytotoxicity, DNA fragmentation assay for detection of apoptotic cell death, LDH activity assay for detection of necrotic cell death, and measurement of $DiOC_{6}$ (3) retention for detection of mitochondrial membrane potential (MMP). Background : Nitric oxide (NO) is believed to playa key role in the process of pancreatic -cell destruction leading to insulin-dependent diabetes mellitus (IDDM). Results : Exposure of RINm5F cells to chemical NO donor such as S-nitroso-N-acetylpenicillamine (SNAP) induced cytotoxic events such as DNA fragmentation and lactate dehydrogenase (LDH) release into medium. However, pretreatment of RINm5F cells with CR extract ($10~50{\mu\textrm{g}}/ml$) for 3 hours prevented SNAP-induced DNA fragmentation and LDH release into medium through the inhibition of MMP disruption. Conclusions : These results suggest that CR may be a candidate for a therapeutic or preventing agent against IDDM.

The effect of dietary feeding of silk fibroin/sericinmixtureson the antioxidative status and glucose metabolism in high fat-fed mice was investigated. The mice weregiven experimental diets for 6 weeks: normal control (NC),high fat (HF) andhigh fat supplemented with F100 (pure fibroin, HF-F100), F81 (81:19 fibroin-sericin, w/w, HF-F81) or F50 (50:50 fibroin-sericin, w/w, HF-F50). The silk protein-fed mice showed decreased lipid peroxidation, enhancedantioxidant enzymesactivities and lower blood glucose level relative to HF group. The HF-F50 animals exhibited significantly lower insulin level, higher glycogen concentration, enhanced hepatic glucokinaseactivity and reduced glucose-6-phosphate and phosphoenolpyruvatecarboxynaseactivities than the HF ones. The $in$ $vivo$ antioxidant activity and hypoglycemic action tended to increase with increased amount of sericin and decreased fibroin content in the diet. These findings demonstrate that silk protein, particularly sericin, may be beneficial in suppressing high fat diet-induced hyperglycemiaand oxidative stress.

Objective: Skeletal muscle is a crucial tissue from the perspectives of mitochondrial dysfunction and insulin resistance, it is formed by myogenesis which is dynamic multistep process to be myotubes. The authors could found that root of Atractylodes macrocephala Koidzumi (Atractylodis Rhizoma Alba, ARA) enhanced glucose and lipid metabolism in C2C12 myotubes via mitochondrial regulation. However its action in myogenesis process is not known. The aim of this work was the study of ARA on proliferation, differentiation and hypertrophy in C2C12 cells. Methods: To study proliferation phase, cells were incubated in growth medium with or without ARA (0.2 or 1.0 mg/ml) for 24 hours. To examine differentiation, at 70% confluence, cells were transferred in differentiation medium both with/without ARA (0.2 or 1.0 mg/ml) for 96 hours. And after 72 hours of differentiation, cells were treated with or without ARA (0.2 or 1.0 mg/ml) for 24 hours, the genesis of hypertrophy in myotubes were analyzed. Results: In proliferation phase, ARA could make difference in morphologic examination. In differentiation phase, it also made morphologic difference furthermore ARA (1.0 mg/ml) increased mRNA expressions of Myogenic regulatory factors and muscle-specific proteins synthesis. In late differentiation, ARA induced hypertrophic morphological changes in neo-formed myotubes. Conclusions: ARA might control cell cycle promoting myogenesis and hypertrophy in C2C12 cells.
