The purpose of this study was to develop a motivational enhancement therapy(MET) for impaired fasting glucose(IFG) patients in early stages of health behavior change and evaluate its effects on health promotion lifestyle, the stages of change and HbAlc. Data was collected in Health Center of U city, December 2011 to March 2012, conducted on 78 IFG patients who visited to the Health center, they randomized to intervention group(n=27) and control group(n=33). The intervention group received the MET, the control group received standard care. This MET programe was applied from MET programe. After developing, it confirmed content validity. Data was analyzed using descriptive statistics, $x^2-test$ and t-test with the SPSS WIN 20.0 program. Participants in the intervention group reported significantly increased scores of the stage of change(t=-20.224, p=.000) compared to those of the control group but no difference of health behaviors(t=-1.297, p=.200) and HbAlc(t=.794, p=.431). The findings indicate that the MET is an effective intervention in improving ealth behaviors and expect to be applied effectively to the preparation for implementation of health care interventions.

This study examined the relationships among impaired fasting glucose (IFG), diabetes and periodontal disease. The data from 10,856 adults (aged over 19 years) was derived from the Fifth Korean National Health and Nutrition Examination Survey, which was conducted in 2010 and 2012. Adjusting the related confounders, multiple logistic regression analysis showed that periodontitis were related to gender, age, education level, smoking and diabetic status (p<0.001). These findings suggest that abnormal fasting glucose, which is a predisposing factor for diabetes mellitus, does not appear to be a risk indicator for periodontal disease. On the other hand, if patients do not take steps to prevent or delay diabetes, prediabetes is likely to develop into type 2 diabetes within 10 years. Therefore, patients with prediabetes need to undergo continuous examinations and management of periodontal disease.

The Purpose of this study was to investigate the effect of dietary sea tangle in diabetic rats treated with streptozotocin(STZ). Four groups of rats (Sprague-Dawley male rats,180-200g) were normal rats fed control diet(C), diabetic rats fed control diet(CD), normal rats fed sea tangl diet(T), and diabetic ,rats fed sea tangle diet(TD), diabetes was induced by single injection of streptozotocin(60mg/kg B.W.). High density lipoprotein(HDL) of T and TD group were higher than other groups(C and T groups). And the weekly change of blood sugar was decreased in the 3th and 4th weeks. But serum triglyceride (TG) of diabetic rats fed sea tangle diet(TD) was lower than diabetic rats fed control dlet(CD). Activity of hepatic microsomal Glucose 6-phosphatase(G6Pase) was significantly increased CD and TD groups higher than C and T groups. Hepateic glutathione S-transferase(GST of T, CD and TD groups were significantly lower than C group(p<0.05), glutathione peroxidase (GPX) of T and TD groups were significantly higher than C and CD groups(p<0.05).

Male Sprague-Bawler rats were blocked into four groups which were normal rats fed control diet (NC) diabetic rats fed control diet (DC), normal rats fed Hamcho powder diet (NH), and diabetic rats fed Hamcho powder diet (DH). Diabetes was induced by single injection of streptozotocin (60 mg/kg B.W. i.p.). The animals were fed ad libitum for 5 weeks. Malondialdehyde (MDA), glucose 6-phosphtase (Gspase), glutathione S-transferase (GST) glutathione Peroxidase (GPx), and glutathione reductase (GR) activities were measured in the homogenates of liver and kidney, and total lipid, total cholesterol, triglyceride, and HDL-cholesterol concentrations in the blood serum. Food and water intakes were markedly higher in diabetic groups than those of normal groups and were not significantly decreased by Hamcho powder supplementation, But, FER (Feed efficiency ratio) of DH Brood was higher than that of U group. Total cholesterol level of DH group was decreased in the second and third week, and the weekly change of blood sugar was also decreased in the 5th week. Dietary Hamcho intake showed 41.2% of hypoglycemic effect in diabetics rats. Levels of total lipid and triglycerides of DH group were lower than those of DC group. Hepatic GR activity of DH group was higher than those of other groups. However, renal GR activity was lower than those of other groups. Hepatic G6Pase activity was significantly high in DH group and reduced by Hamcho powder supplementation. GST was reduced by Hancho diet in diabetic rats. In conclusion Hamcho supplementation decreased serum lipid and glucose concentration in STZ-induced diabetic rats and this effects of Hamcho might exert antidiabetic effect of Hamcho powder diet.

The effects of dietary eggs on liver and serum lipids, serum protein and mineral concentrations, and enzyme activities in male rats were studied. Sprague-Dawley rats were fed four types of diets for 4 weeks, respectively: a control diet, a control diet supplemented with 5, 10 or 15% eggs powder. In rats fed 5, 10 or 15% egg diets the body weight gain, the food intake, the weights of kidney and epididymal fat pad were similar to those in rats fed the control diet. The hepatic weight, hepatic cholesterol and triglyceride concentrations of rats fed the all egg diets were significantly higher than those of rats fed the control diet. The concentrations of total cholesterol, HDL-cholesterol, LDL+VLDL-cholesterol, triglyceride and phospholipid in the serum of rats fed the all egg diets were similar to those of rats fed the control diet. In the rats fed 5% egg diet the HDL-cholesterol/total-cholesterol ratios was significantly increased, and the atherogenic index was significantly decreased compared with those in the rats fed 10 or 15% egg diets. The serum total protein and albumin concentrations of rats fed 10 or 15% egg diets were significantly increased compared with those of rats fed the control diet. The serum calcium levels of rats fed the all egg diets were significantly increased compared with those of rats fed the control diet. No differences were noted in the concentrations of urea nitrogen, creatinine, glucose and hemoglobin, and activities of GOT, GPT, ${\gamma}-GTP$ and alkaline phosphatase in the serum among the rats with on all the experimental diets. These results showed that the all egg diets feeding increased cholesterol and triglyceride concentrations in liver, but no differences lipids and lipoprotein cholesterol concentrations in serum of rats.

This study was designed to investigate whether Loranthus parasiticus extract (LPE) could inhibit the activities of carbohydrate digestive enzymes and alleviate postprandial hyperglycemia in diabetic mice. Lyophilized L. parasiticus was extracted with 80% ethanol and concentrated. The inhibitory effects of LPE on carbohydrate digestive enzymes were evaluated by examining α-glucosidase and αamylase, and it was seen to inhibit the activities of both enzymes in a dose-dependent manner. More specifically, the IC50 values of LPE against α-glucosidase and α-amylase were 0.121±0.007 and 0.157±0.004 mg/ml, respectively, significantly lower than those of acarbose, showing that LPE has stronger inhibitory effects than the positive control. These results suggest that LPE strongly inhibits the activities of these digestive enzymes. Blood glucose levels in the control group of diabetic mice increased to 490.00±28.52 mg/dl and 474.60±25.30 mg/dl at 60 and 120 min after a meal, respectively. However, when LPE was added to starch, postprandial blood glucose levels were significantly reduced (463.0±23.73 and 418.5±24.50 mg/dl at 60 and 120 min, respectively; p<0.05). The area under the curve also significantly decreased following administration of LPE, with no cytotoxicity. These results therefore indicate that LPE could be used as an α-glucosidase and α-amylase inhibitor and delay carbohydrate digestion and, thus, glucose absorption after a meal.

The purpose of this study was to investigate the UCP-1, UCP-3 mRNA expression in brown adipose tissue with glycometabolism according to intensity and duration of swimming in rat. F344 rat were randomly divided into three groups (n=10 in each group): control (CON), low-intensity swimming (LIS) groups, and high-intensity swimming (HIS) groups. Animals in the LIS group were forced to swim in swimming pool for 30min once a day for 8 consecutive weeks with a light intensity. In the HIS group, the rats repeated fifteen 20-s swimming bouts with a weight equivalent to 10% of body weight for 8weeks, respectively. The present result demonstrated that in LIS group, serum insulin and glucose levels significantly decreased in LIS group compared to CON. Brown adipose tissue UCP-1 and UCP-3mRNA expression was significantly increase in LIS group compared to CON and HIS groups. From those results, it can be suggested that low-intensity swimming may improve glycometablism control by up-regulating UCP-1 and UCP-3mRNA expression.

A new vacuum assisted auto-lancing technique is proposed to minimize pain. Specially designed lancing device was introduced, which applied -100mmHg right after skin puncture on the forearm. Sampled blood volumes were measured in 58 normal females. Mean volume of 464 samples was approximately 2.6$\muL$ and the frequency of more than 0.5$\muL$ was 86%. Thus the success rate of blood sugar test should also be the same when using modern glucose meters capable of testing with only 0.3~0.5$\muL$ of capillary blood. When pain scores were quantitatively evaluated by the visual pain measure, only 23% pain of the traditional finger sampling was experienced, demonstrating that capillary blood sampling was performed on the forearm with almost no pain. The present technique reduced pain to a great degree, though resampling might be unavoidable due to 14% of test failure rate estimated for modern glucose meters. However, minimized pain makes the present technique of great convenience for diabetic patients who need blood sampling a few times a day.

To investigate the physiological activities of hot water extract and solvent fractions isolated from Pleurotus ferulea, antioxidative, fibrinolytic, thrombin inhibitory, and ${\alpha}$-glucosidase inhibitory activities were examined. Pleurotus ferulea, hot water extract was fractionated into hexane, chloroform, ethyl acetate, butanol and water fraction. Each of these was assayed individually. The antioxidative activities of ethyl acetate and butanol fractions were 86.79% and 87.82%, respectively. Using the fibrin plate method, only the ethyl acetate fraction showed a plasmin activity of 0.08 units/ml. Thrombin inhibitory activities of chloroform and ethyl acetate fractions were 74.90% and 71.08%, respectively. In the ${\alpha}$-glucosidase inhibitory activity test, butanol fraction showed the highest activity at 49.67%. From the above results, we anticipate that solvent fractions of Pleurotus ferulea can be used as a materials for the development of biofunctional foods for cardiovascular diseases.

Urine glucose monitoring system is a self-monitoring system that display the glucose level by non-invasive measurement method. In this paper, We developed a noninvasive urine glucose monitoring system that improved defects of urine glucose measurement with a colorimeter method and invasive blood glucose measurement method. This system consist of bio-chemical sensor for urine glucose measurements, signal detecting part, digital and signal analysis part, display part and power supplying part. The developed bio-chemical sensor for the measurement of urine glucose has good reproducibility, convenience of handing and can be mass-produced with cheap price. To evaluate the performance of the developed system, We performed the evaluation of confidence about the detection of glucose level by a comparison between a standard instrument in measuring glucose level and the developed system using standard glucose solutions mixed with urine. Standard error was 2.85282 from the evaluation of confidence based on regression analysis. Also, In analysis of S.D(standard deviation) and C.V(coefficient of validation) that are important parameters to evaluate system using bio-chemical sensor, S.D was 10% which falls under clinically valid value, 15%, and C.V was under 5%. Consequently from the above results, compared to blood glucose measurement, the system performance is satisfactory.
