Objective: We aimed to evaluate associations between the ratio of serum estrone (E1) to estradiol (E2) and parameters related to serum glucose metabolism and insulin resistance in women with polycystic ovary syndrome (PCOS). Methods: In total, 133 women between the ages of 18 and 35 diagnosed with PCOS were enrolled in this study. All participants with PCOS underwent blood tests to determine hormonal and biochemical metabolic parameters and a standard 2-hour 75-g oral glucose tolerance test. They were divided into two groups according to the serum E1-to-E2 ratio: group 1 (E1/E2 ratio <2.0) and group 2 (E1/E2 ratio ≥2.0). Results: In the comparative analysis, the waist-to-hip ratio (WHR) was the only clinical variable that was significantly different between the two groups. Patients with a higher E1/E2 ratio showed higher fasting insulin levels, homeostasis model for insulin resistance, and postprandial glucose level at 2 hours (PPG2). In a correlation analysis, only PPG2 was significantly related to the serum E1/E2 ratio. However, after controlling for the confounding effects of body mass index (BMI) and WHR, fasting glucose was also significantly correlated with the serum E1/E2 ratio. Conclusion: Women with PCOS with a higher serum E1/E2 ratio were found to be more likely to show higher fasting insulin and postprandial glucose levels. Significant correlations were found between the serum E1/E2 ratio and both fasting and postprandial serum glucose levels after adjusting for BMI and WHR in women with PCOS.

The purpose of this study is to analyze that ICT-based primary health care affects clinical changes of participants in the primary care chronic disease management pilot project using ICT medical care. Customized health information data, provided by National Health Insurance Service, was used for the analysis. The study targeted a total of 676 people that participated in primary care chronic disease management pilot project using ICT medical care from 2017 to 2018. Hierarchical regression was used to test three model. First, there were many subjects who used face-to-face consultation and non-face-to-face consultation(messaging), but less than half of patients using non-face-to-face consultation(telephone). Second, after participating in the pilot project, the fasting blood sugar level decreased. Third, the clinical condition of the subjects appeared to be an important factor in controlling blood sugar levels. Finally, patients using the non-face-to-face consultation(messaging) had reduced blood sugar levels after participating in the project. This results imply that non-face-to-face consultation is effective in reducing fasting blood sugar level with hospital intervention, and there are effects of the primary care chronic disease management project using ICT.

Onion (Allium cepa Linn) has been reported to have hypoglycemic activity in human and several animal models. In the present study, we performed intraperitoneal glucose tolerance test (IPGTT) in young (1.5mo) and aged (5 mo) rats treated with onion in order to determine whether aging can influence on the anti-hy-perglycemic effect of onion. In addition, we investigated the hypoglycemic effect of onion in streptozotocin- induced diabetic rats treated with aqueous extracts of onion (500 mg/kg, i.p., daily) for 4 weeks. Blood glucose level was determined in fasted and fed rats by using a glucometer (Johnson & Johnson). In glucose tolerance test, blood glucose level was maximally increased 15 min after glucose load (2 g/kg, i.p.), and recovered to the basal level 3 hr after glucose challenge in young and old rats. The maximum blood glucose levels of young and aged rat were 184$\pm$7.49 and 225.2$\pm$ 12.55 mg/dl, respectively. A single i.p. injection of aqueous extract of onion (1 g/kg) 30 min before glucose challenge significantly decreased blood glucose levels at 15, 30, 60, 90 min after glucose load in aged rats, while the administration of onion did not show any significant effect in young rats. In onion-treated diabetic rats, significant hypoglycemic effect (p<0.05) was observed, and the effect was greater in fasted rats than in fed. In conclusion, these results suggest that anti-hyperlycemic effect of onion can be changed by age and fasting.

$^{99m}Tc-Pertechnetate\;(TcO_4^-)$ is concentrated by the stomach after intravenous injection, allowing the detection of ectopic gastric mucosa. It has been used to develop a noninvasive test of gastric secretion. However the cellular site of concentration is still controversial, that is whether mucin-secreting epithelial cell or acid-secreting parietal cell. This study is planned to investigate the effects of cimetidine and gastric acidity on the retention of $TcO_4^-$ in the gastric wall of the rat. Also we further attempted to clarify the uptake and secreting cell of $TcO_4^-$ in the gastric mucosa. One hundred rats were divided into two groups, preliminary (40 rats) and main examination group (60 rats). Preliminary examination group was composed of fasting group (20 rats) for the detection of the time for reaching stable $TcO_4^-$ retention ratio in gastric wall and post-prandial group (20 rats) for the detection of the time for reaching the maximal gastric acidity. Main examination group was composed of fasting group (30 rats), which was subdivided into control group (10 rats), cimetidine group (10rats), $Mylanta^{(R)}$ group (10 rats) and post?prandial group (30 rats), which was subaivided into 90 min group (10 rats), 90 min cimetidine group (10 rats), and 120 min group (10 rats). Retention ratio (%) of $TcO_4$ in the gastric wall and the pH of the gastric contents were measured in the extracted stomach of the six groups. Gastric wall retention ratio of $TcO_4^-$ was calculated by the gastric wall radioactivity (cpm) divided by total gastric radioactivity (cpm) at 30 mins after intravenous injection of 0.4 mCi of $TcO_4^-$. The results were as follows: 1) The time required for reaching stable $TcO_4$ retention ratio and the lowest gastric PH were 30 min and 90 min, respectively. 2) In the fasting group, the gastric wall retention ratio of $TcO_4^-$ was significantly increased in the cimetidine group, compared with the control group (P < 0.01). However there was no significant difference between the control and $Mylanta^{(R)}$ group 3) The $TcO_4^-$ retention ratios of 90 min and 120 min groups were lower than that of the fasting control group (p < 0.05), either. After administration of cimetidine, the retention ratio was significantly increased in 90 min group (p < 0.01). 4) While $TcO_4^-$ retention ratio and gastric pH were well correlated in the post-prandial 120 min group (r=0.7112, p<0.05), in the post-prandial 90 min and 90 min cimetidine groups correlated poorly. However, there was no correlation in the three fasting groups at all. Referring the above results, we infer that $TcO_4^-$ is secreted into the gastric lumen by both parietal and non-parietal cells, with dominant non-parietal $TcO_4^-$ secretion in the fasting state and dominant parietal $TcO_4^-$ secretion in the stimulated state.

The Purpose of this study is to investigate the effect of soluble dietary fiber psyllium on insulin sensitivity and skeletal muscle glucose transporter 4(GLUT4) protein expression in stroke-prone hypertensive rats(SHRSP) fed a high-fat diet containing 5% of psyllium or cellulose from five to nine weeks of age. Obtained results were as follows : (1) In the psyllium diet group fasting plasma glucose level was significantly reduced and glucose levels upon oral glucose tolerance test were significantly lower than cellulose diet group at 30 min(p<0.05) and 60 min(p<0.01) (2) Skeletal muscle GLUT4 contents were significantly increased in the soleus(slow twitch) and extensor digitorum longus(fast twitch) muscle of psyllium diet group. (3) However there was no difference in insulin levels in the fasting and oral glucose tolerance test. These results indicated that psyllium diet improves peripheral insulin sensitivity but not insulin secretion. In conclusion our present finding suggest that soluble fiber diet is effective to increase insulin sensitivity in SHRSP. From these results it was suggested that soluble dietary fiber supplementation effectively prevents insulin resistance.

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.

Background: We first launched the case management program for diabetic patients who were registered in NHIC (National Health Insurance Corporation) in Korea and conducted this study to assess the effectiveness of the program. Methods: During the period from October in 2002 to March in 2003, 30 case managers performed the program for 71 diabetic patients. We evaluated the effectiveness of the program based on the results of fasting blood sugar level, two hour post-prandial blood sugar level, knowledge for diabetes, difficulty index in diabetes management, and the health risk factor changes of them. We analyzed results related to these factors through $x^2$ test and paired t-test. Results: The ave rage age of the subjects was 58.9. and the numbers of women and men were 43 and 28 respectively. The fasting blood sugar level and two hour post-prandial blood sugar level decreased from 164.3mg/dl to 146.5mg/dl and from 224.0mg/dl to 203.0mg/dl respectively. The knowledge for diabetes and difficulty index in diabetes management changed from 8.13 to 9.10 and from 3.52 to 2.91 respectively, and these changes were the positive. We observed improvement in self-test of sugar level, foot management, oral hygiene and proper medication but not in self-test of nutritional management. Conclusions: This study revealed that the case management program for diabetic patients who were registered in NHIC is significantly effective. However, the program need to study further to understand its long-term effects.

Although fasting programs have recently attracted close attention because of benefits of detoxification, few studies have examined these programs. This study investigates the effects of a modified juice-based fasting program on lipid metabolism. A total of 33 volunteers fasted for 10 days and participated in program lectures, exercise programs, water bath regimens, and enemas. Pre- and post-program blood samples were obtained to evaluate lipoprotein levels. A paired t-test was conducted using SPSS 18.0. Changes in the lipid profile were observed during the juice-based fasting program and attending 3 degrees. All lipid profiles decreased significantly, including total cholesterol (TC) (p<0.001), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) (p<0.05). Program participation was documented by assessing attendance levels as high, moderate, and low. TC decreased significantly in all programs and levels (p<0.05), TG decreased proportionally only in enemas according to the attending degree: high (48 %), moderate (20 %), and low (10 %). HDL-C decreased at all low levels, but moderate exercise ($53.8{\pm}12.5mg/dL$ to $55.6{\pm}10.2mg/dL$) and a high enema ($54.9{\pm}14.1mg/dL$ to $55.0{\pm}9.4mg/dL$) showed small increases. The antioxidant property of the juice-based fasting program in terms of the blood vessel, enemas, and exercise played an important role in preventing cardiovascular disease from increased levels of HDL-C. These results suggest that juice-based fasting and combined lifestyle programs may help improve lipid metabolism and protect against dyslipidemia.

Purpose: This study aimed to estimate the effects of a health mentoring program on fasting blood sugar, total cholesterol, triglyceride, physical activity, self care behavior and social support changes among community-dwelling vulnerable elderly individuals with diabetes. Methods: A non-equivalent control group pre-post-test design was used. Participants were 70 community-dwelling vulnerable elderly individuals with diabetes. They were assigned to the experimental (n=30) or comparative (n=30) or control group (n=28). The experimental group participated in the health mentoring program, while the comparative group participated in health education program, the control group did not participate in any program. Data analyses involved a chi-square test, Fisher's exact test, a generalized linear model, and the Bonferroni correction, using SPSS 23.0. Results: Compared to the control group, the experimental and comparative groups showed a significant decrease in fasting blood sugar, total cholesterol, and triglyceride. Compared to the comparative and control groups, the experimental group showed significant improvement in self care behavior. However, there were no statistical differences in physical activity or social support among the three groups. Conclusion: These findings indicate that the health mentoring program is an effective intervention for community-dwelling vulnerable elderly individuals with diabetes. This program can be used as an efficient strategy for diabetes self-management within this population.
