Objectives : This study conducted to investigate oral care abilities in diabetic patients to find a good dental method which may efficiently control diabetes. Methods : The diabetic group consisted of 40 patients with type 2 diabetics, while the non-diabetes were 34 persons with no signs of diabetics, who had visited a Public Health Center and dental clinic of a general hospital in Gwangju city from Dec. 2008 to Sep. 2009. Periodontal disease, gingivitis, dental caries, tongue plaque and halitosis between diabetic group and non-diabetic group were examined and at the same time a questionnaire survey was conducted. The data were analyzed with chi-square, t-test, pearson correlation coefficients using the SPSS WIN 15.0 program. Results : The mean values of both the community periodontal index and the gingival index of diabetic group were 2.18 and 1.75, respectively, and those were higher than those (1.79 and 1.50) of non-diabetic group with no statistical significance. The mean saliva secretion of non-diabetics was 16.74 mL, which was higher than 13.90 mL of diabetic patients(p<0.05). The oral care ability(mean 3.10) acquired from plague index in diabetic group was worse than in non-diabetic(mean 2.33). Conclusions : The high blood sugar concentration in diabetic patients causes low saliva secretion and high saliva viscosity, with the results halitosis and periodontal disease take place. This study suggested that good oral care ability of diabetic patients was very helpful to prevent periodontal disease and halitosis. In addition to this, it may reduce complications of diabetic patients.

Purpose: The purpose of this study was to test the effect of 12-week Tai Chi exercise on glucose control, peripheral nerve modulation, and perceived health for Type 2 diabetic patients with neuropathy. Methods: A pretest posttest design with a nonequivalent control group, 44 diabetic patients with neuropathy were recruited from an outpatient clinic of a university hospital and assigned into Tai Chi or Control groups. The Tai Chi exercise was based on Tai Chi for Diabetes program developed by Lam (2006) and performed one hour for each session twice a week for 12 weeks. Outcome variables were HbA1c, Michigan Neuropathy Screening Instrument scores and perceived health. A total of 25 patients completed both measures of pretest and posttest. Results: The study participants were 67 years old in average, diagnosed by DM for more than 15 years. Those who participated in 12-week Tai Chi exercise (n=13) significantly improved in HbA1c (t=2.23, p=.035) and perceived health (t=-2.28, p=.032) than the control group (n=12). Conclusion: Tai Chi exercise may improve glucose control and health status in patients with Type II diabetes. Further study with larger sample size would be necessary to confirm the effect of Tai Chi on peripheral nerve modulation.

Zinc is known to have important effects on insulin activity and to increase the body fat deposition. The purpose of this study was to investigate the zinc status and obesity in 50 type 2 diabetic women visiting public health center and hospital. The mean age was 57.9 $\pm$ 6.9 years old. The mean of diabetic duration was 8.0 $\pm$ 6.5 years. Body mass index (BMI) of diabetes was $23.2 \pm 2.3 kg/m^2$. There were no significant differences of mean age, anthropometric indices, and insulin level other than fasting blood sugar (p < 0.001) and insulin resistance (p < 0.00l) between diabetes and control group. The obesity ratio of diabetes was $20\%$, $66\%$ and $84\%$ for BMI, waist circumference and waist/hip ratio (WHR), respectively. Plasma zinc level was not significantly different between diabetes and control group. However, urinary zinc excretion of diabetes was approximately twice of control group (p < 0.001). Urinary zinc loss was fivefold higher in the hyperglycemia ($HbA_{lc}> 10\%$) than in normal blood glucose (p < 0.001). Anthropometric indices were decreased in hyperglycemia. On the other hand, there were the tendency of increased urinary zinc in obese group for waist circumference and percent of body fat. These results suggested that controlled normal blood glucose could improve hyperzincuria and anthropometric changes in type 2 women diabeties.

Background Chitosan (CS) is a well-known antimicrobial dressing material. Moreover, widely used amniotic membranes contain growth factors beneficial for wound healing. Herein, we created a novel amnion-conjugated CS-alginate membrane dressing and tested its wound healing potency in a diabetic swine model. Methods The bovine amniotic powder growth factor contents were evaluated by protein assay, and the powder's wound healing effects were assessed in vitro by HaCaT cell scratch closure. In vivo, two minipigs developed streptozotocin-induced diabetes. Serial serum glucose measurements and intravenous glucose tolerance tests were performed to confirm their diabetic status. Twelve square-shaped wounds created on each pig's back were randomly divided into control (n = 4), CS (n = 4), and amnion-CS (AC; n = 4) groups and treated accordingly with different dressings. Wound healing in each group was assessed by measuring wound contraction over time, capturing wound perfusion with indocyanine green (ICG) angiography, and histologically analyzing inflammatory markers. Results Amniotic powder elution promoted HaCaT cell migration in the scratch wound model, suggesting its beneficial in vitro wound healing effects. In vivo, the CS and AC groups showed earlier wound contraction initiation and reepithelialization and earlier wound perfusion improvement by ICG angiography than the control group. Additionally, the wound size of the AC group at week 3 was significantly smaller than those in the control group. There was no significant difference in the numbers of acute and chronic inflammatory cells between the groups. Conclusion The amnion-conjugated CS-alginate membrane, as well as CS dressing alone, could be a favorable dressing option for diabetic wounds.

This study was carried out to investigate the supplementary effects of the rice germ oil compared with soy bean oil on blood glucose level of non-insulin dependent diabetic mice. Forty diabetic KK mice were fed two kinds of experimental diets with 20% lipid from soy bean oil as a control(CO) and rice germ oil(RG) for 8 weeks, respectively. Diet intake, body weight, organs weights and lipids levels of serum, liver and feces were measured. There was no significant difference in food and water intake, body weight gain and organs weights between experimental groups. The concentrations of fasting and random blood glucose were similar between CO and RG groups. There was no significant difference in blood glucose levels after glucose treatment during the glucose tolerance test between two groups. The levels of $HbA_{1c}$ as the index of blood glucose status, and insulin were similar in two groups. These results suggested that rice germ oil can't reduce blood glucose concentration of non-insulin dependent diabetic mice compared with soybean oil. But we need to investigate the hypoglycemic effect of rice germ oil by changing supplementary level and period.

The aqueous extract of Coscinium fenestratum was studied for its antioxidant status in STZ-nicotinamide induced type 2 diabetic rats at two dose levels of 250 mg/kg and 500 mg/kg. At the end of the experimental period, diabetic rats treated with aqueous extract at both dose levels showed a significant increase in the levels of enzymatic antioxidants such as glutathione peroxidase, glutathione synthetase, peroxidase, superoxide dismutase and catalase as compared to the untreated control. Similarly, a significant increase was also observed in the levels of the non enzymatic antioxidants ceruloplasmin, ascorbic acid and tocopherol. The results suggest that the aqueous stem extract of C. fenestratum prevents type 2 diabetes mellitus induced oxidative stress.

Objectives: The increased prevalence of antibiotic resistance is an outcome of evolution. Most patients presenting with odontogenic space infections also have associated systemic co-morbidities such as diabetes mellitus resulting in impaired host defense. The present study aims to compare the odontogenic spaces involved, antibiotic susceptibility of microorganisms, length of hospital stay, and the influence of systemic comorbidities on treatment outcome in diabetic patients. Materials and Methods: A 2-year prospective study from January 2012 to January 2014 was conducted on patients with odontogenic maxillofacial space infections. The patients were divided into two groups based on their glycemic levels. The data were compiled and statistically analyzed. Results: A total of 188 patients were included in the study that underwent surgical incision and drainage, removal of infection source, specimen collection for culture-sensitivity, and evaluation of diabetic status. Sixty-one out of 188 patients were found to be diabetic. The submandibular space was the most commonly involved space, and the most prevalent microorganism was Klebsiella pneumoniae in diabetics and group D Streptococcus in the nondiabetic group. Conclusion: The submandibular space was found to be the most commonly involved space, irrespective of glycemic control. Empiric antibiotic therapy with amoxicillin plus clavulanic acid combined with metronidazole with optimal glycemic control and surgical drainage of infection led to resolution of infection in diabetic as well as nondiabetic patients. The average length of hospital stay was found to be relatively longer in diabetic individuals.

In Korea, there are many kinds of functional foods to manage diabetes, however, they have not been evaluated or investigated systematically. The purpose of this study was to investigate the status of recognition and intake of functional foods among diabetic patients. The study subjects were 307 patients(male 135, female 172), who diagnosed with type 2 diabetes at Seoul National University of Bundang Hospital. Questionnaire survey was done from July to October, 2004 for the characteristics of patients and factors related to the use of functional foods. The mean age of the subjects was 64$\pm$10.2 years, and the mean duration of disease was 9.5$\pm$8.90 years. Approximately 49.8% of the subjects had experience to use functional foods at least once in past. Total number of functional foods used were 56 types. Red ginseng was used most frequently(27.9%), then followed by Silkworm powder(13.6%), Vitamin supplements(10.4%), Mulberry tree(7.1%), Cordyceps sinensis(6.8%) and Ginseng(4.2%). Functional foods were introduced by their friends.relatives(38.4%), family(29.1%), internet(13.9%), and the mass media(10.6%). Among respondents, 94.7% took functional foods with conventional diet therapies(diet, exercise and medication). The purpose of functional food use was to control blood glucose level(49.0%), to relieve fatigue and improve stamina(19.9%), to treat and prevent a disease(17.2%) and to help blood circulation(7.9%). Upon the question of further recommendation of functional foods to others, 74.8% of the subjects answered negative response. However, 12.6% of the subjects showed the further intention of using new product. Therefore, to guide the appropriate use of functional foods for diabetic patients, diabetic educator should provide the knowledge of the efficacy of functional foods and the desirable guidelines.

This study was designed to examine the effects of Salicornia herbacea L. (glasswort: GW) on hepatic antioxidative enzyme activities in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats weighing 200-220g by an injection of streptozotocin (STZ) dissolved in a citrate buffer into the tail vein at a dose of 45 mg/kg of body weight. Sprague-Dawley rats were fed an AIN-93 recommended diet and the experimental groups were fed a modified diet containing 10% and 20% of glasswort powder for 4 weeks. The experimental groups were divided into 6 groups which consisted of normal (N)-control group, N-GW 10% and N-GW 20% treated groups, STZ-control, STZ-GW 10% and STZ-GW 20% treated groups. The activities of Xanthine oxidase (XOD), glutathione- S-transferase (GST), glutathione peroxidase (GPX), glutathione reductase (GR), superoxide dismutase (SOD) and CAT (CAT) were measured in the homogenates of liver. The activity of CAT was lower in the supplementary group with glasswort compare to the STZcontrol group but it was not significantly different. The activity of SOD was not significant in all of experimental groups. The activity of GR was significantly increased in the normal supplementary group with glasswort, and GPX activity was significantly increased in STZ-GW 10% group compare to the STZ-control group. The activity of XOD was significantly decreased in the all of supplementary groups with glasswort. The activity of GST was significantly increased in the N-GW 20% group and it was significantly decreased in the STZ-GW 20% group. These results show that the supplementation of glasswort may have favorable influence on antioxidative status in diabetic rats and it may be useful for the diabetic complications as functional food.

This study was designed to examine the effects of diets containing different levels of seeds of Benincasa hispida(wax gourd) on glycogen, protein levels and lipid profiles as well as malondialdehyde (MDA) in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley rats were induced diabetes mellitus by STZ injection (45 mg/kg) into the tail vein and were divided into four groups: normal, STZ-control, and two experimental groups. Normal and STZ-control groups were fed the AIN-93 diet and the two experimental groups were fed a modified diet containing 2.5% and 5.0% of wax gourd seed powder for four weeks. The liver, muscle, lung, kidney, and pancreas were excised after sacrifice, then the glycogen, protein, and lipid peroxidation products were measured. The rats fed 2.5% wax gourd seed group showed higher levels of liver glycogen compared with that of the STZ-control group. The levels of kidney protein were significantly increased in the 2.5% and 5.0% wax gourd seed groups. There were no significant difference cholesterol and liver triglyceride levels of the liver and MDA concentration in the liver, lung, and kidney among all four groups. These results show that wax gourd seed treatment of 2.5% and 5.0% doses did not exhibit profound anti-lipid peroxidation properities.
