Purpose: The purpose of this study was to evaluate the effect of antioxidant vitamins and magnesium supplementation on fasting blood glucose and lipids in patients with type 2 diabetes. Methods: This study is a unequivalent control group pretest-posttest design. Seventyone subjects with type 2 diabetes who were recruited from home visiting clients of a public health center, completed the trial. The experimental group entered a 12-week treatment period with antioxidant vitamins and magnesium and the control group with no antioxidant vitamins and magnesium. Results: Serum level of fasting blood glucose decreased from $134.7mg/d{\ell}$ to $125.0mg/d{\ell}$ and total-cholesterol decreased from $215.5mg/d{\ell}$ to $198.2mg/d{\ell}$ in the experimental group. No changes in fasting blood glucose and total-cholesterol were demonstrated in the control group. Conclusions: A short-term supplementation with antioxidant vitamins and magnesium can reduce fasting blood glucose and total-cholesterol in patients with type 2 diabetes. The continuous effect of this supplementation and the beneficial effect on the prevention of diabetes complication still needs to be demonstrated.

This study was performed to investigate the average fasting blood sugar levels from various Homeless and the old at nursing homes. Subjects (297 Homeless and 190 aged people) were examined in April, 2011 to June, 2010 in Daegu city area and only fasting blood sugar was measured. Subjects consist of 274 (56.30%) men and 213 (43.70%) women but primarily comprise over 60s. Blood was collected by vein-puncture, centrifuged and analyzed by TBA-C8000. The number of each subject for blood sugar levels of men groups were shown 197 (40.50%) with under 110, 24 (4.90%) with 110~125, and 53 (10.90%) with over 126. On the other hand, 127 (26.10%) with under 110, 33 (6.80%) with 110~125 and 53 (10.90%) with over 126 from women groups. This means that the average prevalence rate of diabetes is approximately 10% at each sex. Depending on age, the fasting blood sugar level over 126 increased with advancing age but the significance of results was not shown. Two groups, Homeless and aged people at nursing homes, the fasting blood sugar level was alittle high (2.9%) from Homeless but not significant. Regular blood sugar test and HbA1c test for people could be play an important role to prevent diabetic disorders under the government's interest.

Objectives: The modified fasting therapy(MFT) of traditional korean medicine uses very low calorie diet on a patient with chronic disease and obesity. During the fasting period of MFT, calorie intake is restricted under 600kcal. Adverse events such as hunger, heartburn, headache, and hair loss can occur because of fasting. In case of Gilbert's syndrome, Jaundice can arise without disorder of liver function and hemolysis because of increase of unconjugated bilirubin. We experienced a case of Gilbert's syndrome patient who appeared jaundice during the fasting period, so we report about that with literature review.

Effect of fasting and refeeding on growth and blood chemistry of juvenile olive flounder Paralichthys olivaceus L. was investigated when fish achieved compensatory growth. Fish were fed the experimental diet for 6 days a week. Five treatments in triplicate were prepared: C, S1, S2, S3 and S4. Fish in the control group (C) were hand-fed to apparent satiation twice a day. Fish in treatments of S1, S2, S3 and S4 experienced 1, 2, 3 and 4 weeks of starvation and were then hand-fed to satiation twice daily during the remaining 7, 6, 5 and 4 weeks of the experiment, respectively. Weight gain of fish in C, S1 and S2 were higher than those of fish in S3 and S4. A significant difference in plasma total protein, glucose, triglyceride, $T_3$ and $T_4$ was observed in between starved and refed fish for the rest periods of the feeding trial. Plasma total protein and $T_3$ of flounder decreased with week of fasting and following correlationships were obtained; Y (Total protein) = -0.13X (week of fasting) + 1.54, $R^2=0.9792$ and $Y(T_3)=-11.48X$ (week of fasting) + 79.57, $R^2=0.8822$, respectively.

To elucidate the effect of a 4 week dietary supplementation with pumpkin water extract on serum lipid and fasting glucose levels, 41 female collegians residing in the Gyeonggi area were recruited. The subjects were divided into three groups: placebo-control (PC, n=11), treatment A (TA, 100 ml/day, n=13), and treatment B (TB, 300 ml/day, n=17). Total serum cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, triglyceride (TG), and fasting glucose were analyzed. The average age, height, weight, and body mass index of the subjects were 21.3 years, 161.1 cm, 53.0 kg, and 20.4 $kg/m^2$, respectively. The average total cholesterol, HDL-cholesterol, LDL-cholesterol, TG, and fasting glucose level (mg/dl) were 171.4${\pm}$26.1, 63.5${\pm}$11.4, 92.6${\pm}$22.9, 76.8${\pm}$32.0, and 89.1${\pm}$8.2, respectively. There were no significant differences among the three groups in any measured parameters, and between the pre- and post-study values of the all parameters. The results indicated that the 4 week pumpkin water extract supplementation (100 ml, 300 ml) did not influence the serum total cholesterol, HDL-cholesterol, LDL-cholesterol, TG and fasting glucose level in female collegians.

Maintenance of fasting blood glucose levels is important for glucose homeostasis. Disruption of feedback mechanisms are a major reason for elevations of glucose level in blood, which is a risk factor for type 2 diabetes mellitus that is mainly caused by malfunction of pancreatic beta-cell and insulin. The fasting blood glucose level has been known to be influenced by genetic and environmental factors. Mitochondria have many functions for cell survival and death: glucose metabolism, fatty acid oxidation, ATP generation, reactive oxygen species (ROS) metabolism, calcium handling, and apoptosis regulation. In addition to these functions, mitochondria change their morphology dynamically in response to multiple signals resulting in fusion and fission. In this study, we aimed to examine association between fasting blood glucose levels and variants of the genes that are reported to have functions in mitochondrial dynamics, fusion and fission, using a cohort study. A total 416 SNPs from 36 mitochondrial dynamics genes were selected to analyze the quantitative association with fasting glucose level. Among the 416 SNPs, 4 SNPs of PRKACB, 13 SNPs of PPP3CA, 6 SNPs of PARK2, and 3 SNPs of GDAP1 were significantly associated. In this study, we were able to confirm an association of mitochondrial dynamics genes with glucose levels. To our knowledge our study is the first to identify specific SNPs related to fasting blood glucose level.

Food intake is regulated by both central and peripheral mechanisms. In the central nervous, the hypothalamus acts for autonomic and endocrine homeostasis. The paraventricular nucleus(PVN) of hypothalamus is an imprtant site of interaction in central feeding pathways. Neuroepetide Y(NPY)is one of the most powerful neurochemical stimulants of food intake known. Also brain nitric oxide(NO), known as neurotransmitter, is involved in the mechanisms that regulate food intake. In this experiment, 24h fasting mice and anorexia mutant mice have been to examine the expression of NPY, which is the major neuropeptide increasing food intake. Double staining with NPY and nicotinamide-adenine-dinucleotide-phosphate diaphorase(NADPH-d), followed by immunohistochemical method and image analysis, have been used to observe coexisting neurons and the level of expression of each neurons. The results were as follows. 1) NPY-immunoreactivitys reduced immune response of the hypothalamus, particularly paraventricular nucleus(PVN), in anorexia mutant mice. Decreased level of NPY is assumed to be a major pathological factor in anorexia mutant mice. On the other hand, PVN in hypothalamus of fasting mice showed increased immunoreactivity which is in agreement of other researchers. 2) NPY and NADPH-d double staining revealed coexisting neurons in the cerebral cortex. Fasting mice had a tendency to have increased level of coexisting neurons compared to the control group. Compared to the control group, fasting mice express is not increase level of NPY-immunoreactivity, while anorexia mutant mice tended to have a decreased level.

Dietary therapy is one of the most important treatments for obesity. In general, it is difficult to maintain the recommended diet for weight control for a long time; therefore, it is difficult to achieve weight loss or maintain weight. Intermittent fasting has recently become one of the most popular diets for weight loss. Intermittent fasting is a strategy of repeating intermittent energy restriction and eating, unlike conventional diets of continuous calorie restriction. Studies on intermittent fasting have shown positive results not only in terms of weight loss but also improvement in metabolic indicators, such as glucose control and reduction of blood pressure. Therefore, it is important to maintain a long-term dietary strategy to prevent weight loss in obese individuals. The effect on weight loss was similar to that of an existing continuous energy-restricted diet. However, long term studies and safety data are still lacking, and large-scale studies with various populations are needed. If more evidence is secured for various individuals, it can be expected that intermittent fasting, including time-restricted eating, will be applied clinically in the future.

IGFs and IGFBPs have an important role in controlling glucose homeostasis. This study was conducted to investigate the changes of insulin-like growth factor(IGF)-I. IGF-II and IGF binding proteins (IGFBPs) on fasting and postprandial state in Korean diabetes, Twenty eight healthy subjects and fifty seven diabetic patients participated in this study. The healthy subjects were not knowingly suffered from any disease and were not receiving any medical treatment, and diabetic subjects were undergo medical treatment, continuously. Weight and height were measured and body mass index (BMI) was calculated as weight (kg) divided by the square of height (m2). Blood pressure was measured. Plasma lipid profiles were analyzed by enzymatic methods, plasma Insulin and glucose levels were measured in fasting and postprandial state, respectively. The levels of serum IGFs and IGFBP-3 were measured by radioimmunoassay (RIA). The levels of glucose and insulin were significantly higher in diabetes than normal subjects on fasting as well as postprandial state (p<0.0l). The levels of IGF-I was significantly lower in diabetes than normal subjects, however in postprandial state, there was no significant difference between diabetes and control subjects, The levels of IGF-II were significantly lower in diabetes than control subjects both fasting and postpradial state, The level of IGFBP-3 were not significantly different between diabetes and normal subjects. Fasting IGF-I, IGF-II and IGFBP-3 levels were positively correlated with those levels on postprandial state, fasting IGe levels of IGF-I levels were positively correlated with fasting insulin levels, and postprandial IGF-I levels were positively correlated with fasting glucose, postprandial insulin and postprandial insulin levels, plasma triglyceride levels were correlated with plasma triglyceride levels. The IGFBP-3 levels were not correlated with IGF components, glucose, insulin and plasma lipids, These results demonstrate that in diabetes, the components IGF-I/IGFBPs system were significantly correlated with plsma glucose and insulin levels both fasting and postprandial state.

To investigate the effects of different type of dietary fat on survival metabolism of fasting rats, one group rats (FO) were fasted, another one group rats (BM) were fed normal diet and the others were fed only one of the following fat diets: beef tallow (FT), corn oil (FC), and perilla oil (FP) of 11.4g/kg respectively. Most FO group rats survived for 6 days and large part of the only-fat-diet groups rats survived for 16 days. Body weights of all rats in fasting and only-fat-groups, measured just one day prior to death owing to fasting or caloric malnutrition, decreased by 24.5%~25% only-fat to fasting rat somewhat extended the survival time but the specific properties of dietary fat types had no remarkably differential effect on survival time and body weight gain rate. The features of liver and kidney weight gain rate of all rats in fasting and only-fat-diet groups were similar to those of body weight gain rate. In FO groups blood levels of total-cholesterol, triglyceride, and glucose markedly reduced whereas GPT activities and BUN levels considerably increased as compared to BM group. However the types of dietary fat perse did not affect blood total cholesterol, triglyceride, glucose, BUN levels, and GPT activities in early stage of fasting in FC and FP group. GPT activities in rats of FP group just prior to death of starvation seemed to be affected by the dietary fat types. The results showed that only-fat-feeding to fasting rats somewhat extended survival time but the types of dietary fat had no remarkably differential effect on survival time and metabolism of fasting rats.
