Abstract
Background: Type2 Diabetes mellitus (T2DM) is non communicable disease including hyperinsulinemia, insulin resistance, hyperglycemia and low grade chronic inflammation associated with various micro and macro vascular complications .
Objectives: The present study aimed to estimate the Vitamin D , total antioxidant capacity and Malondialdehyde (MDA) levels in T2DM patients compared with healthy volunteers, further to find out vitamin D association between HbA1c, total antioxidant capacity , MDA, lipid profile levels
Materials and methods: Seventy type 2 diabetic patients with age group of 35 to 50 years were selected and 70 healthy age matched subjects were selected as controls. Serum Vitamin D and Insulin was estimated by ELISA, Glycosylated hemoglobin (HbA1C) was assessed by HPLC method and other routine lipid profile investigations carried out by Beckman Coulter fully automated analyzer.
Results: Vitamin D levels were significantly decreased in type 2 diabetic patients. HbA1C and insulin resistance values are significantly increased in type 2 diabetic patients. Vitamin D levels Negatively correlated with MDA, insulin resistance , HbA1c and positively correlated with total antioxidant capacity . But there is no significant correlative changes observed between lipid profile parameters.
Conclusion: Vitamin D deficiency may be one of the vital risk factor responsible for increased oxidative stress in T2DM patients. Regular monitoring and supplementation of vitamin D beneficial for reduction of oxidative stress and vascular complications in T2DM patients.

Abstract
Introduction:
Diabetes mellitus (DM) is a metabolic disease characterized by hyperglycemia, disturbed lipid metabolism and cardiovascular disease (CVD). Worsening of glycemic control resulting in lipid and lipoprotein abnormalities suggests that dyslipidemia is secondary to insulin resistance or factors closely related to insulin resistance. Glaciated hemoglobin (HbA1c) is a routinely used marker for long-term glycemic control and is a form of hemoglobin that is chemically is a process called post translational glycosylation that reflects the amount of plasma glucose concentration during the recent 2-3 months.
Methods:
In this cross-sectional study blood collection was done from 598 cases who attended … the laboratory. In two groups categorized of DM and non-DM cases, HbA1c and total cholesterol (T-chol), TG, LDL-C, and HDL-c were determined.
Results:
There was significant association between HbA1c and lipid profiles of DM patients.
Conclusion:
According to the results of this study, HbA1c could be used as a viable marker of lipid and glycemic control in diabetics.

Abstract
Background and aims: Leptin and adiponectin, two members of Adipokines, increase lipid metabolism and inhibit lipogenesis. Reduced levels of these cytokines associate to obesity and insulin resistance. Thus, the serum levels of leptin and adiponectin were determined in type-2 diabetic patients with and without metabolic syndrome in comparison to the control group.
Material and methods: Three groups of individuals were involved in this study; 47 type-2 diabetic patients with metabolic syndrome (DM+MetS), 25 type-2 diabetic patients without metabolic syndrome (DM-MetS), and 40 control group with no history of diabetes and metabolic syndrome as control group. Fasting blood samples were collected and the serum levels of fasting blood sugar (FBS), cholesterol, triglyceride, HDL-Cholesterol and LDL-Cholesterol were measured by the enzymatic method; blood pressure, body height and weight with stadiometers; leptin and adiponectin by the enzyme-linked immunosorbent assay.
Results: There was a significant difference among the groups in serum leptin(p=0.004) and adiponectin(p=0.000) levels. In patients with type-2 diabetes and metabolic syndrome, serum leptin (p=0.530) and adiponectin(p=0.000) were lower in comparison to the control group.
Conclusion: A decrease in the serum level of important adipokines such as leptin and adiponectin in type-2 diabetic patients can be a predictor of metabolic syndrome.

Abstract
Abstract Background and objectives: In diabetic patients, infectious disease is one of the most important cause of admission, and sometimes a life threatening condition. The aim of this study was to determine the clinical features of infection in the hospitalized diabetic patients. Material and Methods: In This retrospective study, we evaluated the files of 122 diabetic patients aged over 20 years in 2004-2005. According to medical document coding, the data was collected by a checklist and then descriptive statistical analysis performed. Results: The subjects’ age is 57+11.76 years (23-83). The Mean time of diabetes diagnosis is 12.62+9.27 years. Sixty-six of them are male (54.5%).and the rest female. most of them (62.2%) were used oral hypoglycemic drugs on admission. Their median fasting blood sugar was 224mg/dl and 164mg/dl for the first and second measuring, respectively. The etiologies are soft tissue infection and diabetic foot ( 49.3%), sepsis(36%),pneumonia(5.7%),urinary infection(3.2%) and unknown(5.7%). None of diabetic foot patients was given specific education for taking care of their feet. Conclusion: in sixty -five percent of the subjects, fasting blood sugar was not in normal limit. Soft tissue infection and diabetic foot was the most infectious cause of admission. It seems that frequent control of blood sugar and foot- care related education can prevent from the most common cause of hospital admission in these patients.

Abstract
Gestational diabetes mellitus (GDM) is the most common metabolic disorder during pregnancy which is associated with 3 to 4 folds of increase in the risk of maternal and fetal morbidity, if it is not diagnosed early (1). Gestational diabetes occurs from 1% to 14%, and 90% of pregnancy-related diabetes has been related to gestational diabetes (2). Glucose challenge test (GCT) and glucose tolerance test (GTT) are recommended by American Diabetes Association (ADA) for screening and diagnosing of gestational diabetes (3).
In this cross-sectional study, the subjects were the pregnant women during 24-28 weeks of gestation referred to Khatam-o-allanbia laboratory of Arak city in 2009. First, we explained the aim of the project and then obtained the written consent. After being fast for at least 8-12 hours, five ml of their venous blood was drown. For GCT, the blood samples were obtained one hour after consumption of 50g of glucose powder. The Individuals whose GCT was equal or higher than 130 mg/dl were introduced for GTT in the future days.
After 8-12 hours of being fast, blood samples were taken to perform GTT. Then after eating 100 grams of glucose powder, their 1, 2 and 3 hour -venous blood samples were drown to perform glucose test, using glucose testing kit of Pars Azmun Company and Mindary BS-300 autoanalyser.
The average age of referred pregnant women is 27.37±10.24 year. Of 417, 403 (96.64%) have normal fasting plasma glucose (≤ 99 mg/dl) and 14 (3.36%) have abnormal fasting plasma glucose (≥ 100 mg/dl). When normal GCT is considered ≥140 mg/dl and ≥130 mg/dl, 357 (85.61%) and 308 (73.56%) have normal GCT and 60 (14.39%) and 109 (26.14%) have abnormal GCT, respectively. The Average of fasting plasma glucose (FPG) and GCT are 83.86 (73-243) and 118.32 (140-351) mg/dl, respectively. In 9 (64.29%) of women with abnormal FPG, the GCT test is also abnormal.
By performing GTT for the women whose GCT was equal or higher than 130 mg/dl, 24 (5.76%) were identified with gestational diabetes and introduced for treatment. If 140 mg/dl was considered as a cutoff point of GCT, four women (0.94%) would falsely be non-diabetic. Based on this study, the prevalence of GDM is 5.74% that is not so high, compared to the range of 4.8 to 7.4% of the country (4). A study conducted by Soheilykhah et al. on 1071 pregnant women with GCT of ≥ 130 mg /dl, 31.9% of the women had abnormal GCT. After doing GTT, 110 patients (10.2%) have been diagnosed with gestational diabetes (2) that is higher than the prevalence of other studies in Iran.
Due to results of this study and other studies, it seems that the GCT is not a reliable test for screening gestational diabetes. On the other hand, if GCT is going to be used, further studies are required to review the current Cutoff point of this test.

Abstract
Abstract Background and Objective: Some studies show that, there is a relationship between decrease of serum magnesium (Mg) level and the insulin resistance in diabetic type II patients. The aim of this study was to compare the Mg level in in type II diabetic with non-diabetic individuals. Materials and Methods: Diabetic patients(n=35) and control group (n=35),<35 years old, were randomly selected from the hospital of Imam Ali, Andimeshk. To compare diabetic patients and control group, the t-student statistical method and SPSS software, were used. Results: Mg levels in diabetic and non diabetic groups were 1.33±0.27 and 1.62±0.21 mg/dl, respectively, and the difference was statistically significant (p=0.0000014). A reversed significant relationship was seen between FPG and Mg among type II diabetic patients, whereas no significant relationship was seen between Mg and other variables, (TG, Chol and HDL). In non-diabetics group, there was a reversed significant relationship between the Mg and Chol, Whereas, no relationship was seen between other variables and magnesium. Conclusion: In diabetic patients, with increased level of FPG, serum Mg levels were decreased significantly. Moreover, serum Mg levels in diabetic patients were significantly lower than non-diabetics. Keywords: Magnesium, Diabetes type 2, Cholesterol, Triglyceride, High density lipoprotein

Abstract
Background and Objective: One of the diabetes complications is the tissue damage caused by the imbalance of oxidants and antioxidants (oxidative stress). The aim of the present study was to evaluate the activity of two antioxidant enzymes -superoxide dismutase and catalase- in the serum of streptozotocin-induced diabetic rats.
Material and Methods: This investigation was conducted on adult male rats assigned to diabetic and control groups. Diabetes was induced by a single intraperitoneal injection of streptozotocin. Seven weeks after diabetes induction, glucose concentration, superoxide dismutase and catalase activities of the serum were assessed.
Results: Glucose concentration of streptozotocin-injected animals was significantly higher than that of control group (P<0.001). The level of Serum superoxide dismutase and catalase activities in diabetes group were significantly higher than those in control group (P<0.01). There was a positive significant correlation between glucose concentration and superoxide dismutase and catalase activities (P<0.001).
Conclusion: The high activity of antioxidant enzymes in diabetic rats is probably due to compensation responses to oxidative stress produced by high concentration of free radicals. It seems that the higher glucose concentration, the greater compensatory responses.

Abstract
Abstract Background and Objective: Recently, diabetes mellitus has been known as one of the main cause of upper gastrointestinal symptoms. Since a high prevalence of H. Pylori in diabetic patients has been reported, we aimed to evaluate the level of gastric juice Nitric Oxide (NO°), Oxidative Stress and Glycated Hemoglobin. Material and Methods: In case group, the participants were 60 diabetic patients infected with H. Pylori, and in control groups 60 diabetic patients without H. Pylori and 60 healthy individuals. The level of NO° in gastric juice was measured calorimetrically and the activity of superoxide dismutase (SOD) and glutathione peroxidase (GPX) in gastric biopsy was determined using standard methods. The percentage of Glycated Hemoglobin (HbA1C) was measured by ion exchange chromatography. Results: In case group compared to controls, significantly increased level of blood HbA1C, nitric oxide in gastric juice, activity of SOD and GPX in the gastric mucosa were observed (p<0.0001). Conclusion: A significant increase of glycated hemoglobin in diabetic patients with H. Pylori and high activity of antioxidant enzymes in the case group may indicate a high production of reactive oxygen species and the presence of oxidative stress in these patients.

Abstract
Background and Objective: Diabetes mellitus is associated with cardiomyopathic changes, can be mediated by an oxidative stress. We aimed to study the effects of regular aerobic training and arbutin supplementation on total oxidant status (TOS) and total antioxidant (TAS) status in the cardiac tissue of diabetic rats.
Material and Methods: fourty-two male Wistar rats with an average weight of 195 to 220 gr were randomly divided into 6 groups (7 rats per group) of control, diabetes, Arbutin, diabetes + Arbutin, diabetes + aerobic training and diabetes + aerobic training + Arbutin. Swimming training protocol consisted of 5 days/week for 6 weeks and each session was 5-36 min/day. Diabetes was induced with alloxan intraperitoneally and Arbutin (50 mg/kg) was administered subcutaneously.
Results: Induced- diabetes significantly increased TOS and decreased TAS in rat heart tissue (P = 0.000). Six weeks of supplementation with Arbutin, aerobic training and combination of aerobic training and Arbutin supplementation were associated with a significant decrease in TOS (88%, 91% ,103% Respectively ) and increase in TAS (33% ,62% ,67% Respectively ).
Conclusion: Compared to arbutin, aerobic training can be more effective in creating adaptation in the antioxidant defense system.

Background and Objective: Oral candidiasis is a common opportunistic infection in diabetic patients. Candida albicans is colonized on different oral surfaces such as tongue, palate, dental caries and plaques. This study aimed to determine the prevalence of Candida albicans in the mouth of diabetic patient.
Material and Methods: This cross - sectional study was conducted on 120 diabetic patients. After completing the questionnaire, the saliva samples were obtained and cultured on sabouraud agar medium containing 0.005% chloramphenicol. For final diagnosis, Germ tube test and Sugar absorption test (with API 120 kit) were used.
Results: Of 120 patients, 61 (50.8%) were positive for Candida. Candida infection rate was relatively higher in older patients and in women. The rate was significant in the patients using dentures (P< 0.001) and the ones keeping on smoking (P <0.038). The infection in the patients with type II diabetes was higher than the cases with Type I.
Conclusion: Given the high prevalence of Candidiasis and Candida colonization in the mouth of diabetic patients, it is a necessity to identify and treat these infections in order to prevent further complications.

Abstract
Background and Objective: Diabetes mellitus is the most common risk factor for coronary artery disease (CAD). Cholesteryl ester transfer protein (CETP) TaqIB polymorphism is associated with changes in lipid profile and may be a risk factor for CAD in patients with diabetes. This study aimed to evaluate the association of CETP TaqIB polymorphism with CAD in patients with type 2 diabetes.
Methods: In this case-control study, 292 diabetic patients were divided into two groups based on angiography reports (150 participants with normal angiogram as the control group and 142 participants with more than 50% stenosis of at least one coronary artery as the case group). The CETP TaqIB genotypes were determined by PCR-RFLP analysis. Fasting blood glucose was measured using glucose oxidase and lipid profile (triglycerides, total cholesterol, high density lipoprotein-cholesterol and low density lipoprotein-cholesterol) by an enzymatic method.
Results: There was no significant difference in the frequency of genotypes and alleles between the case group and controls (the control group: B1B1, 17.3%; B1B2, 63.3%; and B2B2, 19.3%; the case group: B1B1, 18.3%; B1B2, 64.1%; and B2B2, 17.6%) (P=0.92). In the control group, heterozygous participants (genotype B1B2) had higher levels of cholesterol compared with other genotypes (B1B1 and B2B2). Also, the patients with genotype B1B2 had significantly higher weight (P=0.013).
Conclusion: There is no significant correlation between CETP TaqIB polymorphism and the increased risk of coronary artery disease in patients with type 2 diabetes.

ABSTRACT
Background and Objective: The current challenge of diabetes mellitus is to prevent its complications. These complications are directly associated with hyperglycemia in diabetics. The HbA1c measurement is essential for long-term glycemic control. Synchronization of HbA1c measurement is important in order to avoid discrepancies between results reported by laboratories. This study aimed to evaluate the accuracy, precision and agreement of five HbA1c measurement methods with HPLC reference method.
Methods: HbA1c levels of 55 samples were measured using six methods of microcapillary electrophoresis (Sepia), enzymatic method (Pishtaz Teb), immunoturbidometry (Pars Azmoon), boronate affinity (Nycocard), immunofluorescence (ichroma) and Tosoh G8 HPLC.
Results: The five tested methods showed a good agreement with the HPLC method with correlation coefficient of less than 95%. Regression testing of HPLC method and other methods showed slope of 0.99 (P<0.05) for Sebia, 1.02 (P<0.05) for Pishtaz Teb, 0.79 (P<0.05) for Pars Azmoon, 0.82 (P<0.05) for Nycocard and 0.89 (P<0.05) for ichroma. Average inaccuracy for the Sebia, Pishtaz Teb, Pars Azmoon, Nycocard and ichroma in comparison with the HPLC reference method were -0.09, -0.004, -0.75, -0.79 and -0.78, respectively.
Conclusion: The Sebia microcapillary method and Pishtaz teb enzymatic method have appropriate accuracy and precision. Therefore, these methods can be used as alternatives to the HPLC method for HbA1c measurement. Other methods such as Pars Azmoon, Nycocard and ichroma have significant shortcomings in terms of accuracy.

ABSTRACT
Background and Objective: Vitamins C and E are the two main antioxidants involved in prevention of type 2 diabetes, by reducing oxidative stress. The aim of this study was to evaluate the effects of vitamins C and E supplementation independently, on serum levels of insulin, high sensitivity C-reactive protein (hs-CRP) and resistin in people with type 2 diabetes.
Methods: In this study, 38 patients with type 2 diabetes (17 men and 21 women) received 1,000 mg/day vitamin C, and 40 patients with type 2 diabetes (21 men and 19 women) received 400 IU/day vitamin E orally. Fasting blood glucose and lipid profile were measured using enzymatic method. Hs-CRP was measured by immunoturbidimetric method, and serum insulin and resistin levels were measured by ELISA.
Results: total cholesterol, triglycerides, hs-CRP, insulin and resistin significantly were reduced after vitamin C supplementation (P<0.001). Moreover, the level of total cholesterol (P =0.018), low-density lipoprotein, triglycerides and hs-CRP significantly changed after vitamin E supplementation (P=0.001).
Conclusion: The daily intake of 1,000 mg of vitamin C and 400 IU of vitamin E may be useful in reducing diabetic complications by decreasing serum levels of hs-CRP and lipid profile in people with type 2 diabetes.

ABSTRACT
Background and Objective: The relationship between diabetes mellitus and increased risk of cardiovascular diseases has been demonstrated. The aim of this study was to determine the fatty acid profile of epicardial adipose tissue in diabetic and non-diabetic patients with cardiovascular disease.
Methods: In this study, 28 diabetic and 40 nondiabetic patients were evaluated. The epicardial adipose tissue and blood samples of patients were collected during surgery. Non‐esterified fatty acids and phospholipids were measured by the thin layer chromatography and gas chromatography.
Results: Saturated free fatty acids (12: 0) level was higher in diabetic patients compared to nondiabetic patients (P=0.038), while saturated free fatty acids (16: 0) was significantly lower in diabetics (P=0.011). Unsaturated fatty acid (20: 3n-9) was higher in nondiabetics compared to diabetics (P=0.015). There was a significant decrease in level of monounsaturated fatty acids in diabetic patients. The epicardial adipose tissue of diabetics showed a significant increase in free fatty acid (18: 0) and conjugated linoleic acid levels, while there was a significant decrease in the level of free fatty acid (18: 1n-11). Level of epicardial omega-3 free fatty acid (20: 5 n-3) and 22: 6 n -3 was significantly reduced in these patients.
Conclusion: Differences in the serum free fatty acid profile of the two groups may be due to differences in their diet, while changes in the fatty acid composition of epicardial adipose tissue in these two groups could be due to impaired metabolism of fatty acids such as uptake, movement and androgen synthesis as a result of diabetes. These changes increase the risk of developing atherosclerosis in diabetic patients.

ABSTRACT
Background and Objective: Osteoporosis is one of the complications of diabetes. The aim of this study was to determine the impact of resistance training along with Portulaca oleracea supplementation on OPG and NFκB levels (bone markers) in women with type II diabetes.
Methods: Overall, 28 women with type II diabetes (44 to 60 years old) were randomly and equally assigned into four groups (supplement, training, training-supplement and control). An eight-week resistance training program (three one-hour sessions per week with one repetition maximum) was performed using three types of bands with different resistances, at 40-50% intensity and 50-70% maximum heart rate. P. oleracea seeds were supplemented daily (7.5 grams mixed in yogurt) for eight weeks. The data was analyzed using descriptive statistics, paired t-test and ANOVA.
Results: After 8 weeks, OPG and NFκB levels in the three groups of supplement, training and training-supplement increased and decreased, respectively. The highest change in both variables was observed in the training-supplement group. Moreover, the level of these two variables in the training-supplement group had significant difference with the controls and other groups (P=0.000).
Conclusion: As a non-pharmacological therapeutic approach, the regular resistance training and P. oleracea supplementation can increase bone formation markers and reduce bone resorption in women with type II diabetes.
