Background: Sanguisorba officinalis has been used in traditional Asian medicine owing to its beneficial effects on various diseases. The purpose of this study was to evaluate the effect of S. officinalis on the antioxidant system of Streptozotocin (STZ) and Alloxan (ALL) induced diabetic rats. Methods and Results: Triglyceride and Low-Density Lipoprotein (LDL)-cholesterol levels decreased in the STZ-induced diabetic groups treated with S. officinalis extract (SOE) compared to the corresponding levels in the control groups. Moreover, in the ALL-induced diabetic groups, SOE reduced triglyceride, LDL-cholesterol, and High-Density Lipoprotein (HDL)-cholesterol levels. Malondialdehyde (MDA) levels decreased significantly in the STZ and ALL-induced groups treated with SOE compared to the corresponding levels in the control group. Further, Glutathione (GSH) levels increased but did not reach statistical significance. The levels of Superoxide Dismutase (SOD) and Glutathione-S-Transferase (GST) showed a tendency to recover with SOE treatment in the STZ and ALL-induced diabetic groups. In addition, Catalase (CAT) levels in the SOE treatment group decreased significantly compared to those in the control group. Conclusions: These results suggest that SOE might be an effective agent in attenuating oxidative stress in diabetic patients by improving blood lipid profiles and inducing the anti-oxidative enzyme systems.

Purpose : This study is designed to determine the prevalence of cardiovascular autonomic neuropathy and its relationship to risk factors in adolescents with diabetes mellitus(DM). Methods : Ninety-two diabetic patients(80 with type 1 DM and 12 with type 2 DM), ranging from eight to 26 years of age, were studied for cardiovascular autonomic function, and the relationship to age, duration of diabetes, glycated hemoglobin(HbA1c), urinary albumin excretion, and the presence of diabetic retinopathy and abnormal nerve conduction velocities(NCV) were analysed. Autonomic function was assessed by measuring heart rate variation during valsalva manoeuvre, deep breathing and standing from a lying position(30 : 15 ratio), and postural hypotension. Results : Among patients with type 1 DM, 22.5% had early, 8.7% had definite, and 1.3% had severe autonomic dysfunction, and among patients with type 2 DM, 16.7% had early, 8.3% had definite, and 8.3% had severe autonomic dysfunction. On logistic regression analysis including both type 1 and type 2 diabetic patients, the age of the patient(OR=1.133(1.003-1.279), P<0.05) and duration of diabetes(OR=1.148(1.009-1.307), P<0.05) significantly predicted cardiovascular autonomic dysfunction while HbA1c, blood pressure, urinary albumin excretion, and presence of diabetic retinopathy and abnormal NCV did not. The valsalva ratio was borderline or abnormal in 31.5% of patients, the heart rate variation on deep breathing in 41.3%, the 30 : 15 ratio in 14.1%, and postural hypotension in 9.8% of patients. The valsalva ratio and the heart rate variation on deep breathing significantly predicted cardiovascular autonomic dysfunction, but the 30 : 15 ratio and postural hypotension did not. Conclusion : Cardiovascular autonomic dysfunction was found in 32.6% of diabetic patients and 10.8 % of patients had definite or severe involvement. The risk of cardiovascular autonomic dysfunction increased with the patient's age and the duration of DM. This study suggests that the valsalva ratio and the heart rate variation on deep breathing are the most useful tests in evaluating the cardiovascular autonomic function in children and adolescents with DM.

Diabetic gastroparesis is a disorder in a diabetic of delayed gastric emptying in the absence of mechanical obstruction. It is estimated that about 20%-50% of diabetics suffer from gastroparesis. Clinical Sympoms include early satiety, bloating, nausea, anorexia, vomiting, abdominal pain, and weight loss. Severe gastroparesis might result in recurrent hospitalization, malnutrition, and even death, but, no exact treatment has yet been established. Electrogastrography has been known to be a simple, non-invasive, and effective method in assessing gastric motility and EGG has been used to diagnosis diabetic gastroparesis and to estimate its prognosis. Recently, two cases of diabetic gastroparesis were observed. For this cases, manual acupucture, electroacupucture, lumbar skin warming and herb medicine were applied. After application of these therapies, gastrointestinal symptoms improved and these therapeutic effects were confirmed in EGG. Moreover, blood glucose control improved, so patients were able to discontinue insulin injection and change to p.o.medication. In light of this encouraging application of oriental medicine, this is reported along with investigation of the literature.

C3GHi, a novel black rice variety developed by conventional breeding has more high contents of cyanidine-3-glucoside (C3G) and a more strong antioxidant than normal black rice. In this study, we investigate the antioxidative potential and anti-diabetic activity of C3GHi and extract of it for the purpose of development of functional materials or replacement meal for diabetic patients. Using in vitro antioxidative activity assay system such as DPPH radical quenching assay, superoxide anion radical scavenging assay, inhibition of lipid peroxidation and DNA breakage assay, C3GHi extract was observed to have more high antioxidative activity than normal black rice breed. The glycemic index of a freeze dried powder of C3GHi brown rice showed $43.7\pm18.8$, which belonged to low GI food (GI of 55 or less). Using in vivo diabetic model such as db/db mice model and streptozotocininduced diabetic model, C3GHi rice extract decrease blood glucose level and inhibit oxidative stress in blood. From the results, we think that the C3GHi varieties have a potential for the functional materials or ingredient of meal replacement for diabetic patients.

Recently the prevalence rate of diabetes in Korea has been increasing rapidly due to high growth of economy and changes in dietary lifestyle. Vascular complication is one of diabetic complications which have frequently occurred by obesity, hyperglycemia and impaired glucose metabolism. Photoplethysmogram(PPG) measured from finger and toe is very useful for evaluation of vascular aging and sclerosis level since the PPG signal represents characteristics of peripheral vascular Several researchers have reported that second derivative of the finger PPG waveform was useful to evaluate vascular compliance and developed various analysis methods for vascular compliance. However, peripheral vascular compliance study for diabetic patient was never evaluated by using second derivative of PPG. Therefore, we aimed to objectively compare and to assess normal(n=850) and diabetic(n=50) groups vascular compliance using the second derivative of PPG waveform in this study. The evaluated factors of the second derivative of PPG are 'a', 'b', 'c', 'd', 'e' and b/a rapresents vascular compliance. This study found out that when vascular compliance is decreased, the absolute value of b/a is decreased. The average vascular compliance of 50 diabetic patients with neuropathy, $-1.09{\pm}0.14$ is statistically lower than the normal group, $-0.81{\pm}0.09$ (p<0.05). In conclusion, we suggest an objective evaluation of peripheral vascular compliance for diabetic patients and prevention of vascular complication.

Advanced glycation end products (AGEs) formation plays an important role in the progression of diabetic complications. To develop effective herbal formulations with suppression of diabetic nephropathy, a common complication in diabetic patients, we evaluated inhibitory activities of KIOM-79, a new herbal prescription, on the formation of AGEs using in vitro and in vivo model systems. Effects of KIOM-79 on the expression of AGEs, RAGEs (receptor for Advanced glycation end products), type IV collagen and renal $TGF-{\beta}1$ mRNA was also examined in streptozotocon (STZ)-induced diabetic rats. STZ-induced diabetic rats were treated orally with KIOM-79 (250 and $500\;kg^{-1}$ once a day for 13 weeks). In vitro system KIOM-79 suppressed the formation of AGEs $(18.12\;{\mu}g/ml)$. In STZ-induced diabetic rats showing accumulation of AGE and RAGE, pathological examination revealed that KIOM-79 prevented AGE and RAGE deposition in the kidney. In STZ induced diabetic rats, the expansion of mesangial matrix and the glomerular tufts seemed to be larger than those in normal rats. Howεver, after administration with KIOM-79, mesangial metrix and glomerular volume were decreased, and overexpression of type IV collagen was also decreased. Overexpression of renal $TGF-{\beta}1$ mRNA was inhibited significantly. These results suggest that the KIOM-79 might be an effective herbal prescription to prevent or alleviate the progression of diabetic nephropathy.

Objectives: This study was performed to evaluate the impact of glycosylated hemoglobin (HbA1c) level on characteristics and prognosis of maxillofacial fascial infection in diabetic patients. Materials and Methods: We reviewed the medical records of 72 patients (35 patients with HbA1c lower than 7.0% and 37 patients with HbA1c higher than 7.0%) diagnosed with maxillofacial fascial space infection and hospitalized for treatment at the Department of Oral and Maxillofacial Surgery in Dankook University Hospital (Cheonan, Korea) from January 2005 to February 2014. We compared demographics, parameters of glucoregulation (HbA1c), laboratory parameters of inflammation (white blood cell [WBC], C-reactive protein [CRP] count), type and number of involved spaces, type and number of antibiotics, period of hospitalization, number of surgical operations, need for tracheostomy, complications, computed tomography (CT), and microorganisms between the two groups. Results: Compared with the well-controlled diabetes mellitus (DM) group (HbA1c <7.0%), patients in the poorly-controlled (HbA1c ${\geq}7.0%$) DM group had the following characteristics: longer hospitalization periods, higher values of laboratory parameters of inflammation (WBC, CRP count) at the time of admission, higher number of antibiotics prescribed, more frequent complications, frequent deep neck space involvement, and distinctive main causative microorganisms. As the HbA1c level increases, hospitalization periods and incidence of complications increase gradually. Conclusion: This retrospective study suggests that regulation of DM significantly impacts maxillofacial fascial infection. Poorly controlled DM with high HbA1c level negatively influences the prognosis of infection.

Objectives: The goal of this study was to identify association between the continuity of ambulatory care of diabetes patients in South Korea (hereafter Korea) and the incidence of macrovascular complications of diabetes, using claims data compiled by the National Health Insurance Services of Korea. Methods: This study was conducted retrospectively. The subjects of the study were 43 002 patients diagnosed with diabetes in 2007, who were over 30 years of age, and had insurance claim data from 2008. The macrovascular complications of diabetes mellitus were limited to ischemic heart disease and ischemic stroke. We compared the characteristics of the patients in whom macrovascular complications occurred from 2009 to 2012 to the characteristics of the patients who had no such complications. Multiple logistic regression was used to assess the effects of continuity of ambulatory care on diabetic macrovascular complications. The continuity of ambulatory diabetes care was estimated by metrics such as the medication possession ratio, the quarterly continuity of care and the number of clinics that were visited. Results: Patients with macrovascular complications showed statistically significant differences regarding sex, age, comorbidities, hypertension, dyslipidemia and continuity of ambulatory diabetes care. Visiting a lower number of clinics reduced the odds ratio for macrovascular complications of diabetes. A medication possession ratio below 80% was associated with an increased odds ratio for macrovascular complications, but this result was of borderline statistical significance. Conclusions: Diabetes care by regular health care providers was found to be associated with a lower occurrence of diabetic macrovascular complications. This result has policy implications for the Korean health care system, in which the delivery system does not work properly.
