The purpose of this study was to investigate the dietary behavior of people with type 2 diabetes mellitus and to improve their quality of life through medical nutrition therapy. The subjects were 38 persons with type 2 diabetes mellitus visiting a public health center to participate in a dietary education program from Jun, 2003 to Nov. 2003 in Daegu, Korea. The interviews were tape-recorded and analyzed attitude, knowledge, and awareness of patients by focus group interview. Most of the patients were mainly dependent on drug therapy and had little experience of diet education. Barriers to dietary practice adherences were limitations in food selection, lack of will and feel of burden. Barriers to follow guidelines were lack of self-control, confliction with food habits of their family, accessibility, economical problems, fear for the change after dietary practice, food difficulties in meal distribution and difficulties for eating out. After 4 weeks of intensive nutrition education, fasting blood sugar levels were decreased and postprandial and waist circumference were significantly decreased in all patients and 26.9% of patients were under decreased oral hypoglycemic agent dosage due to improved blood sugar level. dietary knowledge of subjects were greatly improved in such items as dietary intake, saturated fat, HbA1C, ideal body weight, and waist circumference.

Diabetes mellitus affects the colonic motility developing gastrointestinal symptoms, such as constipation. The aim of the study was to examine the role of intracellular signaling pathways contributing to colonic dysmotility in diabetes mellitus. To generate diabetes mellitus, the rats were injected by a single high dose of streptozotocin (65 mg/kg) intraperitoneally. The proximal colons from both normal and diabetic rats were contracted by applying an electrical field stimulation with pulse voltage of 40 V in amplitude and pulse duration of 1 ms at frequencies of 1, 2, 4, and 6 Hz. The muscle strips from both normal rats and rats with diabetes mellitus were pretreated with different antagonists and inhibitors. Rats with diabetes mellitus had lower motility than the control group. There were significant differences in the percentage of inhibition of contraction between normal rats and rats with diabetes mellitus after the incubation of tetrodotoxin (neuronal blocker), atropine (muscarinic receptor antagonist), prazosin (α₁ adrenergic receptor antagonist), DPCPX (adenosine A1 receptor antagonist), verapamil (L-type Ca²⁺ channel blocker), U73122 (PLC inhibitor), ML-9 (MLCK inhibitor), udenafil (PDE₅ inhibitor), and methylene blue (guanylate cyclase inhibitor). The protein expression of p-MLC and PDE₅ were decreased in the diabetic group compared to the normal group. These results showed that the reduced colonic contractility resulted from the impaired neuronal conduction and decreased muscarinic receptor sensitivity, which resulted in decreased phosphorylation of MLC via MLCK, and cGMP activity through PDE₅.

Permanent neonatal diabetes mellitus refers to diabetes that occurs before the age of 6 months and persists through life. It is a rare disorder affecting one in 0.2-0.5 million live births. Mutations in the gene KCNJ11, encoding the subunit Kir6.2, and ABCC8, encoding SUR1 of the ATP-sensitive potassium ($K_{ATP}$) channel, are the most common causes of permanent neonatal diabetes mellitus. Sulfonylureas close the $K_{ATP}$ channel and increase insulin secretion. KCNJ11 and ABCC8 mutations have important therapeutic implications because sulfonylurea therapy can be effective in treating patients with mutations in the potassium channel subunits. The mutation type, the presence of neurological features, and the duration of diabetes are known to be the major factors affecting the treatment outcome after switching to sulfonylurea therapy. More than 30 mutations in the KCNJ11 gene have been identified. Here, we present our experience with a patient carrying a novel p.H186D heterozygous mutation in the KCNJ11 gene who was successfully treated with oral sulfonylurea.

BACKGROUND/OBJECTIVES: Complications of diabetes, such as cardiovascular disease, are associated with increased mortality among type 2 diabetes mellitus patients. Homocysteine has been recently identified as a predictor of cardiovascular disease-related complications in diabetes. We investigated whether or not supplementation with folic acid tablets can lower homocysteine levels and improve parameters related with vascular complications. SUBJECTS/METHODS: We conducted a non-randomized 8-week trial involving postmenopausal diabetic women (n = 25) supplemented with $800{\mu}g$ of folic acid ($400{\mu}g$ twice a day) daily. Subjects' serum levels of folate, homocysteine, and vitamin $B_{12}$ were measured, along with vascular function and brachial-ankle pulse wave velocity. RESULTS: Folic acid supplementation significantly increased serum folate levels (P < 0.0001), reduced homocysteine levels (P < 0.0001), and increased vitamin $B_{12}$ levels (P = 0.0063). There were significant decreases in low-density lipoprotein cholesterol levels as well as the ratios of low-density lipoprotein cholesterol to high-density lipoprotein cholesterol and total cholesterol to high-density lipoprotein cholesterol. Brachial-ankle pulse wave velocities were not altered by supplementation. Changes in serum vitamin $B_{12}$ after folic acid supplementation were negatively correlated with changes in brachial-ankle pulse wave velocity. CONCLUSIONS: In this study on postmenopausal Korean women with type 2 diabetes mellitus, folic acid supplementation reduced serum homocysteine levels, increased serum folate and vitamin $B_{12}$ levels, and lowered lipid parameters.

Objectives: This study aims to investigate the effects of diabetes mellitus care mixture (DCM) on blood glucose and lipid metabolism in type 2 diabetic mellitus mice. DCM consisted of lagerstroemia speciose, allium hookeri, momordica charantia, amaranthus tricolor, and boesenbergia rotunda, which have been proven to have antidiabetic properties. Methods: In this study, we researched the effects of DCM in type 2 diabetic mellitus mice. C57BLKS/J mouse groups had no treatment, db/db mouse randomly assigned to 2 groups, and treated with distilled water and DCM (200 mg/kg/day). Blood glucose levels and body weight were checked every week. After 4 weeks of treatment, liver function indicators (AST, ALT, and LDH) and lipid metabolites (triglyceride, total cholesterol, LDL-cholesterol, HDL-cholesterol) were measured with a biochemistry analyzer. Diabetic factors (insulin, resistin, and leptin) were measured with ELISA. Results: DCM was decreased blood glucose, diabetic factors, liver function indicators, triglyceride, total cholesterol, and LDL-cholesterol significantly. Also, HDL-cholesterol was significantly increased in DCM group. The bodyweight of DCM group decreased but, no significant difference with the control group. DCM may have the potential to improved diabetes mellitus by regulating blood glucose levels and diabetic factors. Also protecting from diabetic complications by adjusting liver function indicators and lipid metabolites. Conclusions: These results suggest that DCM to be used as an oriental medicine for diabetes, the results of clinical trials are needed.

Compared to that in the Caucasian population, type 1 diabetes mellitus (T1DM) incidence rates are very low in Koreans. Therefore, compared to the recent development of pharmacological therapy applicable to Korean children with T1DM, interest in nonpharmacological therapy and psychosocial support systems remains low, as is the development of Korean-style T1DM education programs for therapeutic application. Children who have been newly diagnosed with diabetes are placed in completely new environments for treatment. For appropriate control of diabetes, patients have to self-monitor blood glucose levels and inject insulin several times a day and must use extreme self-control when they eat foods to avoid increases in blood glucose levels. Blood glucose excursions resulting from impaired pancreatic ${\beta}$ cell functions cause mental stress due to vague fears of chronic complications of diabetes. In addition, children with diabetes cannot be excluded from the substantial amount of studies required of Korean adolescents, and the absolute shortage of time for ideal control of diabetes adds to their mental stress. Many of these patients are psychologically isolated in school where they spend most of their time, and they are not appropriately considered or supported with respect to blood glucose control in many cases. In this respect, this author will introduce some of the newest views on nonpharmacological therapy and psychosocial support systems that account for important parts of T1DM management and seek measures to apply them in conformity with the social characteristics of Korea.

Background: There has been much research work in the past to ascertain the association between type 2 diabetes mellitus and breast cancer, but definitive evidence has been scanty. The present study was carried out to determine the association of type 2 diabetes mellitus with breast cancer in the female population of Northern Pakistan. Materials and Methods: This case-control study was carried out in the Oncology Department of NORI Hospital. A total of 400 patients were included. Data were entered into PSPP 0.8.1. Two-tailed significance tests were used and a p-value of 0.05 was considered significant. Results: There were a higher percentage of postmenopausal women in the diabetic breast cancer patients' group as compared to the non-diabetic subset. The odds ratio for the association between diabetes and risk of developing breast cancer was elevated with statistical significance (OR = 2.96; 95 % CI =1.3-6.3; p-value=0.004). The results of our study showed that diabetes is associated with a risk of developing breast cancer, especially in postmenopausal women (OR = 4.928; 95 % CI = 2.1-11.3; p-value=0.001). The association was particularly marked in obese subjects (OR = 31.49; 95 % CI = 1.8-536; p- value=0.01), as compared to non-obese subjects (OR = 0.642; 95 % CI = 0.2-1.7). Conclusions: Diabetes is strongly associated with obesity and it tends to increase the risk of breast Cancer, especially in postmenopausal women. A high-risk subset for breast cancer comprised postmenopausal, diabetic and overweight women.
