This study was performed to investigate the effects of puffed and fermented red ginseng on blood glucose-related biomarkers in streptozotocin-induced diabetic rats. Male Sprague-Dawley diabetic rats were orally injected with 0.85% NaCL as a diabetic control (DC), 300 mg/kg general red ginseng (RG), 300 mg/kg puffing red ginseng fermented by mixed strain culture of $Bifidobacterium$ $breve$ and $Lactobacillus$ $delbrueckii$ (BL), and 300 mg/kg puffing red ginseng fermented by $Enterococcus$ $faecalis$ (EF) for 5 weeks. The blood glucose level of group BL was significantly lower maintained than in groups DC and RG for the experimental period (p<0.05). It was also significantly lower than in groups DC, RG, and EF at the 5th week (p<0.05). In the oral glucose tolerance test, the blood glucose of group BL was maintained the lowest level (p<0.05), and the area under the blood glucose curve (AUC) was also significantly lower in group BL than in group DC (p<0.05). The fasting blood glucose and insulin levels after the experiment were significantly low in group BL (p<0.05), and the HOMA-IR was more significantly low in groups BL and EF than in group DC (p<0.05). Also, the HbA1c content of group BL was significantly low than in groups DC and RG (p<0.05). The serum TC level was significantly decreased in groups RG, BL, and EF than in group DC (p<0.05), and the LDL-C content was significantly low in group BL than in group DC (p<0.05). From the findings, it was shown that the puffed and fermented red ginseng made using a mixed strain culture of $B.$ $breve$ and $L.$ $delbrueckii$ could improve blood glucose-related biomarkers.

Purpose: The purpose of this study was to evaluate whether the effect of Intenet diabetes education varied by gender. Method: An experimental group assessed pre- and post intervention was used to assess the effectiveness of diabetes education by nurses. Forty patients separated into two groups by gender partook in the study. The goal of the intervention was to keep blood glucose concentrations close to normal range. The intervention was applied weekly for 3 months. Participants were requested to input their blood glucose level, diet, and exercise diary everyday at http://www.biodang.com by cellular phone or wire Internet. The researcher sent optimal recommendations to each patient using the short message service of cellular phones and wire Internet. All medication adjustments were communicated to the subjects' doctors. The plasma glucose levels, serum lipids, and care satisfaction were measured before and after the intervention. Result: Glycosylated hemoglobin (HbA1c) decreased 1.6% and 0.8% in male and female patients respectively after 3 months of education. Total cholesterol decreased 37.2mg/dl in male patients but increased 80.5mg/dl in female patients. Conclusion: These findings indicated that Internet diabetes education could improve HbA1c and total cholesterol in male patients.

대사증후군은 비만, 이상지혈증, 고혈압, 당뇨병이나 내당능 장애가 동반되어 나타나는 증후군이다. 근래 들어 우리나라도 점차 비만 인구가 증가함에 따라 대사증후군의 유병률이 빠르게 증가하는 추세를 보여. 대사증후군에 대한 간단한 개념 정리를 하였다. 먼저 대사증후군의 정의와 진단기준을 살펴보았다. 1998년 대사증후군을 명명하고 진안기준을 제시한 WHO 진단기준, NCEP-ATP III 진단기준, 인슐린 저항성 증후군의 진단기준을 살펴보고, 기타 인종에 따른 허리 둘레 기준 및 IDF 정의를 살펴 보았다. 또한 대사증후군과 관련된 여러 인자들도 다시 확인해보고, AHA/NHLBI 진단 기준도 살펴 보았다. 우리나라는 대부분 연구에서 NCEP-ATP III 기준을 적용하고 있는데, 그 내용은 복부 비만 허리둘레 남자 102cm 이상, 여자 88cm 이상, 중성 지방 150mg/dl 이상, HDL-콜레스테롤 남자 40mg/dl 미만, 여자 50mg/dl 미만, 혈압 130/85 mmHg 이상, 공복 혈당 110mg/dl 이상이다. 복부 비만의 경우는 2000년 제정된 WHO 서태평양 지역 기준인 남자 90cm, 여자 80cm 이상으로 적용하고 있다. 다음 치료의 기본 개념을 간단히 언급 하였는데, 가장 중요한 치료는 우선적으로 생활 습관의 개선을 꼽을 수 있으며, 기타 약물요법 및 인슐린 저항성 개선제 등이 있다. 우리나라 에서도 심혈관계 질환과 당뇨병이 점차 사망 원인의 우위를 차지 하고 있으므로 대사증후군을 초기에 진단하고 관리하는 노력이 매우 필요할 것으로 생각되며, 생명보험사도 대사증후군을 하나의 증후군으로 인식하여 대사증후군의 전반적인 이해가 필요할 것으로 생각된다.

Objectives: This study was performed to identify the socioeconomic factors, health behavior factors and dietary patterns that have an influence on the fasting blood glucose in adults. Methods: This study used data collected from the 2007, 2008, 2009 Korea National Health and Nutrition Examination Survey. The final sample included 4163 subjects who were 30-59 years old and who had completed the necessary health examinations, the health behaviors survey and nutrition survey. Results: Eleven dietary patterns emerged from the factor analysis with different factor loading. After controlling for potential confounders, multiple regression analysis of the dietary patterns showed that 'fruits', 'alcohols', and 'starchy foods' affected the fasting blood. Lower consumption of 'fruits' and higher consumption of 'alcohols' and 'starch foods' were significantly associated only with an increased risk of high blood glucose. Conclusions: In the light of the results of this study, it appears pretty likely that the risk of developing high blood glucose can be reduced by changing a person's dietary patterns.

Purpose: This study confirmed the effects of body mass index (BMI) and waist circumference (WC) on fasting blood glucose (FBS) and hemoglobin A1c (HbA1c) in adults without diabetes mellitus (DM). Methods: The subjects were 4,659 adults (≥ 20 years), and data were extracted from the 6th National Health and Nutrition Survey 2015 (KNHANES VI-3). The subject's data were analyzed using a complex sample t-test, χ²-test, and multiple logistic regression analysis (SPSS 24.0). Results: The incidence of the high FBS group was increased 1.60 times in males with a WC ≥ 90 cm and 1.78 times in females with a WC ≥ 85 cm. The incidence of the high HbA1c group was increased 1.54 times in those who were overweight and 2.22 times in those who were obese. The incidence of the high HbA1c group was increased 1.99 times in males with a WC ≥ 90 cm and 1.87 times in females with a WC ≥ 85 cm. Conclusion: This study presented evidence that interventions for BMI and WC should be included in DM prevention programs. It also suggested that these findings can be utilized for early detection of DM.

Purpose: Our previous study demonstrated the hypoglycemic effects of mulberry (Morus alba L.) leaf and the underlying mechanisms. Here we explored the potency of mulberry twigs (TW) and root barks (RB) in postprandial hypoglycemic effects in vitro and in vivo. Methods: The major components of TW and RB were determined by high performance liquid chromatography (HPLC). Alpha-glucosidase inhibition and glucose/fructose uptake inhibition in Caco-2 cells were determined for TW, RB, and their major components, followed by an oral sugar tolerance test (OSTT) in streptozotocin-induced diabetic rats. Male Wistar rats were fed a high-fat diet for 2 weeks and then a single dose of streptozotocin (35 mg/kg B.W) was administered by intraperitoneal injection. Rats with fasting blood glucose levels above 126 mg/dL were randomly divided into 5 groups (n = 8/group) for the following treatments by gavage for 4 weeks: vehicle (normal control and diabetic control), 200 mg/kg B.W of TW or RB or 100 mg/kg B.W of oxyresveratrol (OXY). Results: OXY and mulberroside A were identified as the major components of TW and OXY, mongolicin, and kuwanon H for RB. A significant inhibitory activity on ${\alpha}-glucosidase$ was found for TW, RB, and OXY (p = 0.0099). There was a dose-dependent inhibition of TW and RB on the intestinal sugar uptakes in Caco-2 cells, showing a greater impact on fructose compared to glucose. The OSTT showed that TW and RB significantly delayed time to maximal concentration (p = 0.0088) and decreased maximal concentration (p = 0.0043) compared to the control group. Conclusion: These results suggest that TW and RB may have a postprandial hypoglycemic effect, particularly in the case of high fructose or sucrose intake. OXY was suggested as a contributor to the hypoglycemic effect of TW and RB. Further studies are needed for the systemic effect of TW and RB in circulation.

This study investigates the effects of diets with mulberry leaf and Cudrania tricuspidata leaf supplements on blood glucose-related biomarkers in streptozotocin-induced diabetic rats. Male diabetic Sprague-Dawley rats were divided into groups and fed several diets. Group A was fed a diet with a 10% supplement of mulberry leaves. Group B was fed a diet with a 10% supplement of mulberry leaves and an additional 10% supplement of Cudrania tricuspidata leaves. Group C was fed a diet with a 10% supplement of mulberry leaves and an additional 30% supplement of Cudrania tricuspidata leaves. Group D was fed a diet with a 10% supplement of Cudrania tricuspidata leaves. Group E was the DM control. All diets were based on AIN-93G diet and they all lasted 6 weeks. The blood glucose levels of groups B and C stayed similar to initial levels (reference blood glucose) for the experimental period, which was significantly lower than levels in groups A, D, and E at the 6th week (p<0.05). And the area under the blood glucose curve (AUC) was also significantly lower in groups B and C than in groups D and E (p<0.05). The fasting blood glucose level after the experiment was significantly lower in groups B and C (p<0.05), and the C-peptide content of group C was as high as 50 pmol/L on average. The HbA1c content was also significantly lower in groups A and B than in group E (p<0.05). The serum TG, AST, and ALT levels were significantly decreased in groups A, B, and D than in group E (p<0.05). From the findings, it is shown that a diet of 1:1 mulberry and Cudrania tricuspidata leaf supplements could improve blood glucose-related biomarkers.

The aim of this study was to investigate the hypolgycemic activity of water extract of fermented yacon (Smallanthus sonchifolius) leaves tea (Yacon LWE) in high-fat diet (HFD)/streptozotocin (STZ)-induced diabetic mice. Male ICR mice were fed with a HFD (37% calories from fat) for 4 weeks prior to intraperitoneal injection with STZ (100 mg/kg body weight). Diabetic mice were supplemented with two doses of Yacon LWE (0.16% and 0.8%, wt/wt) for 6 weeks. The supplementation of high-dose Yacon LWE significantly lowered blood glucose levels and plasma ALT and AST activities compared with the control group. High-dose Yacon LWE also improved the insulin tolerance without any changes in plasma and pancreatic insulin concentrations in HFD/STZ-induced diabetic mice. Yacon LWE supplementation increased the insulin staining of pancreatic $\beta$-cells in a dose-dependent manner. Both 0.16% and 0.8% of Yacon LWE significantly elevated plasma leptin concentration, hepatic glucokinase activity and glucokinase/glucose-6-phosphatase ratio compared with the control group. However, glycosylated hemoglobin concentration was not different among the groups. These results suggest that high-dose Yacon LWE lowers the blood glucose level partly by enhancing insulin sensitivity and hepatic glucose metabolism in type 2 diabetic mice.

Purpose: Water is magnetically charged upon contact with a magnet. Although magnetic water products have been promoted since the 1930's, they have not received wide acceptance since their effectiveness is still in question; however, some have reported their therapeutic effects on the body, especially the digestive, nervous, and urinary systems. Methods: In this study, the effect of magnetized water on glycemic control of 14 diabetic mice (CB57BK/KsJ-db/db) in comparison with 10 control mice (CB57BK/KsJ-db/+(db/+)) was investigated. Seven diabetic control (DMC) mice and seven diabetic mice + magnetized water (DM+MW) were kept for 16 weeks, followed by intraperitoneal glucose tolerance test (IPGTT). Weekly blood glucose was measured from tail veins. Blood obtained from heart puncture was used for HbA1c analysis. Results: Blood glucose level showed a significant difference starting from the $10^{th}$ week of study ($496.1{\pm}10.2mg/dl$ in DMC vs. $437.9{\pm}76.9mg/dl$ in DM+MW). Blood glucose followed by IPGTT showed no significant difference between groups at 0, 30, 60, 90, and 120 min, although glucose level at 180 min was significantly reduced in DM+MW mice. Plasma insulin level in DM+MW groups was only 39.5% of that of DMC groups ($5.97{\pm}1.69ng/ml$ in DMC vs. $2.36{\pm}0.94ng/ml$ in DM+MW). Levels of HbA1c were 12.4% and 9.7% in DMC and DM+MW groups, respectively. Conclusion: These results show the promising therapeutic effect of magnetized water in regulating blood glucose homeostasis; however, long-term supplementation or mechanistic study is necessary.

The purpose of this study was to investigate the possibility of Meles meles oil as an functional resource. To assess the effects of Meles meles oil in 25 non-insulin dependent diabetes mellitus (DM) persons, we examined changes of fat intake level, hematological and chemical variables, serum DM indices and lipid contents during the Meles meles oil supplementation. Polyunsaturated fatty acid and $\omega$3 fatty acid intake were significantly increased by Meles meles oil intakes. The levels of LDL-cholesterol and triglyceride were significantly decreased while HDL-cholesterol was significantly increased. Iron status improved during Meles meles oil intakes. These results show that modest dose of Meles meles oil supplementation can decrease serum triglyceride, cholesterol level without any changes in blood glucose level in NIDDM patients. These results indicated that Meles meles oil diet is effective therapeutic regimen for the control of metabolic derangements in diabetes mellitus. Also, these results imply that Meles meles oil can be used as possible food resources and functional food materials. However, large amounts of Meles meles oil should be used cautiously in NIDDM patients.
