Fifteen mongrel dogs (14 male and 1 female) were injected intravenously with 30mg of streptozotocin and 50mg of alloxan monohydrate per kilogram of body weight to induce diabetes mellitus. Before treatment with streptozotocin and alloxan fasting serum glucose concentration was determined every other day or thrice a week (Monday, Wednesday, Friday) for 3 months. Among 15 dogs 4 dogs developed diabetes mellitus and survived more than 9 weeks without injection of insulin. After treatment fasting serum glucose and hemoglobin $A_1$ concentrations of the 4 dogs were determined every other day or thrice a week. Fasting serum glucose concentration increased acutely from 24 hours after treatment and then showed severe fluctuation. Hemoglobin $A_1$ concentration increased gradually until 7~9 weeks after treatment and then showed very slow increase afterwards. Correlation of hemoglobin $A_1$ to fasting glucose concentration was relatively weak(r = 0.10~0.80). Hemoglobin $A_1$ and fasting glucose concentration of preceding 7 week showed very high correlation (r = 0.98~0.99). It was indicated that hemoglobin $A_1$ concentration in chemically induced diabetic dogs reflects mean glucose concentration of preceding 7~9 weeks.

The purpose of this study was to Investigate the response of fasting serum glucose and basal insulin to dietary omega-3 fatty fish in normal subjects. Nineteen healthy female volunteer subjects were divided into two groups, depending on fish preference test. Low ap3 fatty acid group for 7 days received a experimental Inlet containing mackeral fish 100g. Calorie intake was 1780 kcal /day. The average 4ally u-3 fatty acid consumption from fish was 3.87g /day (1.03g EPA, 2.849 DHA) . High n-3 fatty acid group was given 7.74g maine u-3 fatty acid (200g mackeral fish) consisting of 2.06g EP45.68g DHA. Calorie intake was 1815 local /day Fasting blond serum glucose, insulin levels were measured at baseline, 7days after experimental diet. In the beginning the levels of fasting serum glucose, basal insulin were not different between both groups. There were no significant changes in fasting serum glucose, insulin levels by experimental diets. These data indicate that marine ar3 fatty acid consumption have no deleterious effect on glycemic control in normal subjects.

Objectives: The American Diabetes Association (ADA) has recently recommended the HbA1c assay as one of four options for making the diagnosis of diabetes mellitus, with a cut-point of $\geq$ 6.5%. We compared the HbA1c assay and the fasting plasma glucose level for making the diagnosis of diabetes among Korean adults. Methods: We analyzed 8710 adults (age 45-74 years), who were not diagnosed as having diabetes mellitus, from the Namwon study population. A fasting plasma glucose level of $\geq$126 mg/dL and an A1c of $\geq$ 6.5% were used for the diagnosis of diabetes. The kappa index of agreement was calculated to measure the agreement between the diagnosis based on the fasting plasma glucose level and the HbA1c. Results: The kappa index of agreement between the fasting plasma glucose level and HbA1c was 0.50. Conclusions: The agreement between the fasting plasma glucose and HbA1c for the diagnosis of diabetes was moderate for Korean adults.

Purpose : The purpose of this study was to investigate the effects of physical activity on impaired fasting glucose in adults aged 20 years or older. Methods : This study utilized raw data from the 8th National Health and Nutrition Examination survey (2019~2021). The subjects of this study were 5,344 adults aged 20 years or older who were confirmed to be free of diabetes. The control variables in this study model are health behavior characteristics (subjective health status, smoking, drinking), anthropometric characteristics (body mass index), and personal background characteristics (gender, age, income level, education level, marital status). As for the analysis method, the degree of physical activity was made into a dummy variable, and a probit model was used. Results : As a result of this study, compared to quartile 1 of the relative grip strength value obtained by dividing the grip strength by the body mass index (body mass index, kg, m²), fasting blood glucose levels were significantly higher in quartile 2 (.05, p<.01), quartile 3 (.04, p<.01), and quartile 4 (.04, p<.01). It was found that the probability of belonging to the normal category was higher than that of impaired fasting glucose. In addition, in the group of adults aged 20 or older who had a lot of aerobic and anaerobic physical activity, fasting blood sugar was more likely to be in the normal category. Conclusion : Based on the results of this study, it was suggested that diabetes should be managed through physical activity in the pre-diabetic stage, as prevention is important as well as treatment. From a practical point of view, muscle strength, such as grip strength, can be identified as a reliable indicator for identifying impaired fasting glucose.

당뇨병은 대사 증후군 및 심혈관 질환을 비롯한 다양한 건강상의 부작용과 관련이 있다. 또한 당뇨병의 증가로 사회 및 의학적 관심이 증가하고 있다. 제 2 형 당뇨병의 특징 중 하나는 혈당이 증가한다는 것이다. 공복 혈당치는 가장 기본적이고 널리 사용되는 당뇨병의 지표이다. TLR4 발현은 심장에서 비교적 높다. 그러나 공복 시 혈당과 TLR4의 관련성에 대한 연구가 있었다. 한국인에서 TLR4 유전자와 공복 시 혈당의 단일 염기 다형성(SNP)의 관련성을 알아 보았다. 서울시에서 총 994 명을 대상으로 TLR4 SNP를 이용한 연구를 실시했다. 공복 시 혈당과 관련하여 TLR4 유전자 영역은 연쇄 불균형으로 나타 났으며 유전자의 범위가 매우 크기 때문에 여러 개의 LD 블록으로 보였다. TLR4 유전자의 SNP는 평균 공복 시 혈당과 관련이 있었다(p<0.01). 공복 시 혈당과 관련 크기는 p-value를 $-log^{10}$의 값으로 하였다. rs1329067의 minor allele frequency는 16.4%였고 AA 유전자형을 가진 사람들은 GG 유전자형을 가진 사람들 보다 공복 시 혈당이 높았다. 이 연구는 TLR4의 유전 적 변이가 한국 성인의 혈당 수치에 영향을 미친다는 것을 암시한다.

This study classified subjects aged 30 to 64 into normal group, impaired fasting glucose group, and diabetes mellitus patient group based on data from the 6th period of the National Health and Nutrition Examination Survey (2013-2015). Skipping breakfast, lack of physical activity, inadequate sleep time, inadequate weight, excessive drinking, and current smoking are classified as a low health risk group when three or less items are present, and a high health risk group when three or more items are included. By classification, each item included in the physical measurement and biochemical analysis factors and health risk behavior factors was comparatively analyzed. As a result, in the normal group, impaired fasting glucose group, and diabetes group, the average age was higher in the group with high health risk factors than the group with low risk factors, and the male ratio was higher. Body mass index, waist circumference, blood pressure, triglyceride showed a significantly higher result. In the normal group, the fasting blood glucose level and total cholesterol level were also higher in group 2. Therefore, it is thought that it is necessary to control health risk behaviors through lifestyle changes in the normal group, fasting glucose disorder group, and diabetes group.

Objectives : To determine the relationship between exercise and the incidence of type 2 diabetes in an impaired fasting glucose group. Methods : This prospective cohort study was conducted in 19,440 men and 4,297 women, aged 30-69 years, with impaired fasting glucose at baseline who had undergone biennial medical evaluation through the National Health Insurance Corporation from 2000 to 2004. Impaired fasting glucose was defined as fasting glucose of 100 to 125 mg/dl and the subjects were divided into 3 groups depending on weekly exercise frequency. Multivariate logistic regression analysis was used to evaluate the association between the baseline exercise status and incidence of type 2 diabetes. Results : During the 4-year follow-up, a total of 3,239 men and 283 women developed type 2 diabetes, a cumulative incidence of 16.6% for men, and 6.5% for women. Also, 1,688 men (21.2%) and 127 women (15.2%) developed type 2 diabetes in the obese group. The adjusted relative risk (RR) of developing type 2 diabetes in non-exercising men was significantly higher than exercising men regularly (RR= 1.375, 95% CI=1.236-1.529)(p<0.0001), and the RR for non-exercising women was higher than exercising women regularly (RR=1.124, 95% CI=0.711-1.778). The RR for non-exercise men/women in the obese group was 1.571 (95% CI=1.351-1.827)(p<0.0001)/1.869 (95% CI=0.846-4.130). Conclusions : Regular exercise is effective in preventing type 2 diabetes in people with impaired fasting glucose, and particularly in obese people. People with risk factors for diabetes should participate in a regular exercise program.

The nutrient intake and association between dish group intake and blood glucose and serum lipid level (TG, cholesterol, LDL and HDL) was analyzed among 3 groups: 452 subjects in normal blood glucose group (NG: fasting blood glucose < 100 mg/dL and 2 hours postprandial blood glucose < 140 mg/dL), 258 subjects in impaired fasting glucose group (IFG: fasting blood glucose 100~125 mg/dL and 2 hours postprandial blood glucose ${\geq}$ 140 mg/dL) and 101 subjects in diabetic group (DG: fasting blood glucose $\geq$ 126 mg/dL and 2 hours postprandial blood glucose ${\geq}$ 140 mg/dL). The data were obtained from the 2005 National Health and Nutrition Survey of Korea. The 811 subjects were adults aged 40~64 without dietary treatment. In nutrients intake, IFG was the highest and DG the lowest in both quantity and quality. DG, especially, had the lowest intake in carbohydrates, fiber, proteins, Ca, P, K, vitamins B1 and C, and consumed the highest amount of alcohol. In macronutrients distribution ratio, the DG diet showed a lower energy intake from carbohydrates but higher from fat than the NG diet, while IFG showed a higher energy intake from carbohydrates and lower intake from fat in supper out of 3 meals and snacks. IFG preferred salt-fermented foods and DG preferred soups, braised foods and kimchi compared to other groups. NG preferred multi-grain cooked rice and both IFG and DG preferred plain white cooked rice. Regarding the association between dish group intake and blood glucose, cooked rice, soups, salt-fermented foods and kimchi were significantly related to blood glucose. In blood lipids, steamed-foods, beverages and fruits were inversely related to the risk of developing type 2 diabetes, whereas cooked rice, stews, saltfer-mented foods, seasoned-fermented foods and seasoned vegetables were directly proportional to the risk of developing type 2 diabetes and related diseases. Therefore, it is beneficial to avoid rich, salty and fatty foods and heavy alcohol consumption for controlling blood glucose and blood lipids, while steamed foods, foods rich in fiber (like multigrain rice) as a staple, and fruits and teas are recommended for preventing or managing type 2 diabetes risks.

Background: Antihyperglycemic effects of Panax ginseng berry have never been explored in humans. The aims of this study were to assess the efficacy and safety of a 12-wk treatment with ginseng berry extract in participants with a fasting glucose level between 100 mg/dL and 140 mg/dL. Methods: This study was a 12-wk, randomized, double-blind, placebo-controlled clinical trial. A total of 72 participants were randomly allocated to two groups of either ginseng berry extract or placebo, and 63 participants completed the study. The parameters related to glucose metabolism were assessed. Results: Although the present study failed to show significant antihyperglycemic effects of ginseng berry extract on the parameters related to blood glucose and lipid metabolism in the total study population, it demonstrated that ginseng berry extract could significantly decrease serum concentration of fasting glucose by 3.7% (p = 0.035), postprandial glucose at 60 min during 75 g oral glucose tolerance test by 10.7% (p = 0.006), and the area under the curve for glucose by 7.7% (p = 0.024) in those with fasting glucose level of 110 mg/dL or higher, while the placebo group did not exhibit a statistically significant decrease. Safety profiles were not different between the two groups. Conclusion: The present study suggests that ginseng berry extract has the potential to improve glucose metabolism in human, especially in those with fasting glucose level of 110 mg/dL or higher. For a more meaningful benefit, further research in people with higher blood glucose levels is required.
