Even though coix (Coix lachryma-jobi L. var. ma-yuen) has many physiological effects, since it has been known to cause sterility, farmers avoid using coix bran as a forage for their livestock. Therefore, as the consumption of coix increases, coix bran, which is a by product of pounding process, becomes a serious issue of environmental problem. Present study examined the physiological effects of coix bran in normal and diabetic rats for its possible use as a functional material. The effects of coix bran supplementation on plasma and hepatic lipid profile were evaluated in rats fed one of the following diet for 12 weeks : chow diet ; chow-bran diet (chow diet＋25% coix bran), high fat diet and high fat-bran diet (high fat diet＋25% coix bran). Additionally, glucose challenge and lipid metabolism in streptozotocin-diabetic rats were also examined. In normal rats, consumption of coix bran remarkably reduced body weight gain in chow or high fat diet fed rats. Additionally, consumption of coix branreduced blood TG, TC and atherogenic index (26%, 24% and 72%, respectively) in chow diet fed rats. Liver TG and cholesterol concentrations were reduced (43% and 49%, respectively) in high fat fed rats by coix bran supplementation. In diabetic rats, fasting blood glucose level was reduced about 25% by coix bran consumption. Also, glucose challenge pattern was improved and resembled normal pattern : it reaches to peak 15~30 minutes after glucose administration and get back to fasting blood glucose level after 90 minutes. Plasma concentrations of TG were elevated in diabetic rats and were reduced to normal level by coix bran supplementation. Liver TG and cholesterol concentrations were also elevated in diabetic rats and reduced to normal level by consumption of coix bran. These results suggest that coix bran may have beneficial effects on blood lipid and glucose level in normal and diabetic rats.

The present study was undertaken to evaluate the effects of 50% buckwheat diet on the body weight, organ weight, urine albumin, urine glucose, plasma glucose and plasma lipid in normal rats and diabetic rats treated with streptozotocin(STZ). The food intake, body weight, the level of urine glucose in diabetic buckwheat groups were not significantly different with diabetic control group. The level of urine albumin was lower in raw and steam buckwheat group than in the diabetic control group. Compared to the normal control group, liver and kidney weights were heavier in the diabetic groups. Pancreas weight was heavier diabetic buckwheat groups than in normal and diabetic control groups. Fasting plasma glucose level of diabetic buckwheat groups significantly decreased by 18-37% compared with the diabetic control group. Plasma triglyceride level of diabetic buckwheat groups significantly decreased by 34-50% compared with the diabetic control group. Plasma total cholesterol level of diabetic buckwheat groups decreased by 15-27% compared with the diabetic control group. The level of HDL-cholesterol was not affected by buckwheat diet. These results indicate that buckwheat is an effective therapeutic regimen for the control of metabolic derangements in diabetics.

This study was conducted to evaluate the effects of home-visiting nutrition education for the elderly with high fasting glucose level in an urban community. The study subjects were 40 elderly people, whose information on general characteristics, anthropometric measurement, biochemical indices, nutrition knowledge, nutrition attitude, dietary habit, food intake and nutrient intake were obtained at baseline. The education group received 6 weekly visits of home-visiting nutrition education from 15 March to 25 April 2004. In the baseline-survey, the education group and non-education group showed no differences in their general characteristics, health-related characteristics, anthropometric measurements, biochemical indices, nutrition knowledge, nutrition attitudes, dietary habits, and food and nutrient intake levels. The difference of mean change of nutrition knowledge, nutrition attitude and dietary habit after home-visiting nutrition education had been studied. The nutrition knowledge score increased by 1.4 in the education group; however, those in the non-education group which increased by 0.4, thus, the differences of mean change were statistically significant (p < 0.05). The nutrition attitude score increased by 1.2 in the education group; however, those in the non-education group decreased by 0.4, thus, the differences of mean change were statistically significant (p < 0.01). The dietary habit score increased by 1.7 in the education group; however, those in the non-education group decreased by 2.8, thus, the differences of mean change were statistically significant (p < 0.01). The difference of mean change of anthropometric indices and biochemical indices in education group and the non-education group was not significant. Looking over the zcereals and their products, vegetables, seaweeds, meats and their products, and fish than the non-education group. The MAR increased by 0.06 in the education group; however, that in the non-education group increased by 0.01, thus, the differences of mean change were statistically significant (p < 0.05). The differences of mean change of fasting blood glucose and biochemical indices after home-visiting nutrition education were studied. Fasting blood glucose decreased by 7.6 mg/dL in the education group; however, in the non-education group which increased by 0.4 mg/dL, the difference of mean change was not significant (p = 0.051). The above findings suggest that home visiting nutrition education increases the nutrition knowledge and nutrition attitude, as well as, it is effective to change dietary habits. If the education period is extended, not fasting blood glucose improvement was insignificant, but fasting blood glucose improvement ability could be found by changing dietary habits.

Background: Migraine patients can be sensitive to external or internal stimuli, such as light, noise, or hormonal changes. Using transcranial Doppler ultrasonography (TCD) with breath-holding method, we evaluated the changes of cerebrovascular reactivity (CVR) to hypercapnia in women with migraine without aura between fasting and postprandial period. Methods: Twelve women with migraine without aura and the same number of age and sex-matched healthy controls with no significant history of headache participated in this study. Using TCD examinations, we studied mean flow velocity in middle cerebral artery with better temporal window. Each subject was examined consecutively before and after a standard meal, together with serum glucose level and blood pressure. CVR was evaluated with breath-holding index (BHI). Results: Postprandial-BHI (mean+SD) was significantly higher than fasting-BHI (mean+SD) in patients group but not in controls (in patient group; postprandial-BHI=1.38, fasting-BHI=1.08, in control group; postprandial-BHI=1.25, fasting-BHI=1.18, P=0.021 and 0.239, respectively). After meal, serum glucose level was significantly enhanced but blood pressure was not in both groups. Serum glucose level of patients showed a tendency of mild positive correlation with BHIs (${\gamma}$=0.448, P=0.032). Conclusions: Although exact mechanisms are unclear, cerebrovascular reactivity of some women with migraine without aura may be influenced by prandial state.

Cassia tora L. seeds have previously been reported to reduce blood glucose level in human and animals with diabetes. In the present study, the effects of Cassia tora L. seed butanol fraction (CATO) were studied on postprandial glucose control and insulin secretion from the pancreas of the normal and diabetic rats. Diabetes was induced by an i.p. injection of Streptozotocin (55 mg/kg BW) into the male Sprague-Dawley rats. The postprandial glucose control was monitored during a 240 min-period using a maltose loading test. In normal rats, rats fed CATO (20 mg/l00 g BW/d) showed lower postprandial glucose levels in all the levels from 30 min up to 180 min than those in the control rats without CATO (p<0.05). In diabetic rats, those levels in the CATO group seemed to be lower during the $30{\sim}180$ min, but only glucose level at 30 min showed significant difference compared to that in the control group. Moreover, CATO delayed the peak time of the glucose rise in both normal and diabetic rats in the glucose curves. On the other hand, when CATO was administered orally to the diabetic rats for 5 days, 12 hr fasting serum glucose level was decreased in the diabetic rats (p<0.05). Degree of a decrease in 12 hr fasting serum insulin levels was significantly less in the diabetic CATO rats as compared to diabetic control rats. On the last day of feeding, P cells of the pancreas were stimulated by 200 mg/dL glucose through a 40 min-pancreas perfusion. Amounts of the insulin secreted from the pancreas during the first phase ($11{\sim}20$ min) and the second phase ($21{\sim}40$ min) in the CATO fed diabetic rats were significantly greater than those in the diabetic control group (p<0.05). These findings indicated that constituents of Cassia tora L. seeds have beneficial effect on postprandial blood glucose control which may be partially mediated by stimulated insulin secretion from the pancreas of the diabetic rats.

Purpose: The purpose of this study was to investigate the depression and, the frequency of blood glucose testing in women type2 diabetic patients. Method: 114 Participants were recruited from the endocrinology outpatient department of a tertiary care hospital in an urban city. Depression was measured by visual analogue scale. Blood glucose testing was measured the frequency during past 1 week. Result: Depression was higher in hyperglycemia patient (fasting blood glucose$\geq$110mg/dl) than in normoglycemia patient(fasting blood glucose <110mg/dl). The blood glucose testing frequency as lower in 50-59 years old than in less than 39 years old. And it was lower in middle school graduate than in college graduate. The blood glucose testing was negatively correlated with patient's age. Conclusion: The depression program should be developed for hyperglycemia diabetic patients. And the blood glucose testing education program should be developed for aged and low educational level patients.

This study was carried out along with the 1990 6th National Tuberculosis Prevalence Survey in order to estimate the prevalence rate of diabetes mellitus among a representative adult Korean population. Fasting blood glucose was measured by diastix (Ames) using glucometer II for seventy seven percent of the population (30 year old or above) residing in 190 enumeration districts randomly sampled from 146,944 general ED. The prevalence of diabetes mellitus of the population was estimated by projecting the ratio of ${\geq}200mg/dl\;PP_2$ of fasting blood sugar level below 120 mg/dl by sex to the study population. Fasting blood glucose and 2 hr. postprandial blood glucose were measured on about 3000 subsampled individuals, and diabetes mellitus was defined by the WHO criteria-FBG${\geq}120mg/dl\;or\;PP_2{\geq}200mg/dl$ when FBG is below 120mg/dl. The results obtained are as follows : 1. Estimated prevalence(age adjusted) of diabetes mellitus was 4.6% for male and 8.1% for female. The age adjusted mean FBG was $93.9{\pm}26.2mg/dl$ for male and $102.9{\pm}31.5mg/dl$ for female. 2. The prevalence increased as age advanced with peak in $60{\sim}69$ years old age group for both sexes. 3. The mean FBG and estimated prevalence rate of diabetes mellitus varied considerably among the populations of fifteen cities and provinces ; it vaired from $87.0{\pm}17.7\;to\;104.6{\pm}34.5mg/dl$ and 1.2% to 8.9% for males, and from $93.3{\pm}25.3\;to\;116.7{\pm}38.6mg/dl$ and 3.4% to 20.8% for females. 4. The mean FBG and prevalence rates were higher among the rural population than those residing in metropolitan areas. 5. The proportion of the people previously treated among the diabetics was estimated to be a little less than one fifth. 6. Factors strongly associated with FBG were age, sex, family history of D. M., BMI, area and educational level among eleven variables.

The purpose of this study was to investigate the effect of soybean on blood glucose and lipid concentrations, and antioxidant enzyme activity in type 2 diabetes mellitus(DM) patients. We divided patients into two groups and fed them, respectively, a basal diet(control group) and a basal diet with 69 g/d of soybean(soybean group) for 4 weeks. Pills with roasted soybean powder were provided to the soybean supplementation group three times a day. Macronutrients intake except dietary fiber was similar between the two groups. No significant differences were observed in dietary intakes or body weight before and after the supplementation. Energy composition ratio of C:F:P was 65:19:16 in the control group, 64:20:16 in the soybean group. The blood parameters of subjects before supplementation, such as fasting blood glucose, postprandial glucose level, total cholesterol, triglyceride, LDL-cholesterol and $HbA_1C$ were not different between the two groups. After supplementation, fasting blood glucose(p<0.001), postprandial glucose level(p<0.001) and serum triglyceride level(p<0.05) were significantly reduced in the soybean group in comparison with the control group. The total cholesterol level was not significantly different between the control and the supplemented group after 4 weeks of treatment. TBARS levels of the soybean group were not significantly different from those of the control group. The activities of catalase(p<0.01) and glutathione peroxidase(p<0.05) were significantly higher in the soybean group compared to the control group. The results of this study suggest that soybean supplementation would be helpful to control blood glucose and serum lipid in diabetic patients. Also, soybean showed an antioxidant activity that may contribute to enhance the effect of antioxidant defense. This activity contributes to protection against oxidative damage in type 2 DM patients. Soybean may have potential use in the disease management of patients with DM.

To investigate the effect of Pinus densiflora on biochemical parameters in type I diabetic rats, we evaluated the changes of body weight, fasting blood glucose level, oral glucose tolerance test (OGTT) and biochemical parameters after the intraperitoneal injection of distilled solution of Pinus densiflora in streptozotocin (STZ)­induced rats. Thirty-seven male Sprague Dawley rats $(180\pm10g)$ were divided into four groups; diabetic mellitus (DM) group received STZ (50 mg/kg BW, i.v.); low level of pine extract (LP) group received Pinus densiflora (5 mg/kg BW, i.p.), high level of pine extract (HP) group received Pinus densiflora (10 mg/kg BW, i.p.) after the single injection of STZ (50 mg/kg BW, i.v.), respectively. Normal control (NC) group received saline. The change of fasting blood glucose level and OGTT were measured using glucocard II, and the change of biochemical parameter were measured by Automatic Chemistry Analyzer (Hitach-747, Japan). Mean body weight change of DM group was retarded greatly by STZ-exposure. While, body weights of LP and HP groups were progressively increased with some fluctuation, although the increase rates were slower than that of NC group. Fasting blood glucose levels of LP and HP groups were reduced by Pinus densiflora injection, although the fasting blood glucose levels were higher than that of NC group. The results of OGTT was significantly improved in both of LP and HP group compared to DM group. Increases of blood glucose, alanine aminotransferase (ALT), alkaline phosphatase (ALP) and blood urea nitrogen (BUN) levels by STZ-exposure were attenuated by the Pinus densiflora treatment (p<0.05). From the results, it was suggested that Pinus densiflora has a tendency to decrease STZ-induced toxicity in terms of monitoring fasting blood glucose, OGTT and some biochemical parameters of rat.

This aim of this study is to assess the association of between glucose level and periodontal diseases in Korea adults. The data for analysis were obtained from Korea National Health and Nutrition Examination Survey 2009. A total of 7,062 subjects who aged 19 years and above, underwent a medical and dental checkups. The prevalence of undiagnosed diabetes group was 27%, and the prevalence of impaired fasting glucose(IFG) group was 41.2%, diabetes group was 43.6% with periodontitis. IFG and diabetes had significantly higher prevalence of periodotontits compared to those having normal after adjusting confounding variables; the odds ratios were 1.35 (95% confidence interval: 1.17 to 1.55) and 1.27 (95% confidence interval: 1.02 to 1.58), respectively. This study has suggested that diabetes increases the risk of periodontal disease. Proactive, preventative dental and diabetes self care, as well as regular dental and diabetes assessment, are important management strategies for impaied fasting glucose and periodotnal health.
