Abstract
Background & Objectives: Diabetes mellitus may be associated with the imbalance between protective effect of antioxidants and increased free radical production with regard to discrepancies of the findings in previous researches the present study set out to determine the changes of plasma malondialdehyde and erythrocyte antioxidant superoxide dismutase activity in patients with type II diabetes mellitus. Methods: This case-control study was conducted in 2005 using random sampling. 38 patients with type II diabetes mellitus who referred to 5th Azar diabetes center and 19 age and sex matched healthy controls were selected for this study. Heparinated blood samples were taken from the cases. The separated plasma was tested for blood sugar, lipid peroxidation and blood cells (for glycolisated Hb and superoxide dismutase enzyme activity). The collected data were analyzed by SPSS (ver. 10) using t-test. Results: The level of plasma malondialdehyde from type II diabetes mellitus patients (6.27±0.80 nmol/ml) was significantly different from that in control group (3.56±0.98 nmol/ml)(p<0.05). Erythrocyte superoxide dismutase activity from type II diabetes mellitus patients (678.78±59.36 U/gr Hb) was significantly lower than control group (1056.47±52.98 U/gr Hb) (p<0.05). Conclusion: The significant difference between the increase in malondialdehyde and decrease in the activity of antioxidant enzymes in patients with type II diabetes mellitus may predispose to the development of serious complications leading to cellular damage. This suggest that diabetic patients may need more antioxidants than normal. Supplementation with medical or non-medical free radical scavengers such as vitamins E and C or foods untaining vitamin C (sitrus fruits) have a potential role in reinforcing antioxidant defence and can be important in diabetic patients.

Abstract
Background & Objectives: Adherence to a diabetic diet is one of the most important aspects of diabetes management. Compliance with a diabetic diet has usually been described in terms of total intake. We examined indexes of the use of specific foods that would normally be either recommended or prohibited by Food Frequency Questionnaire. Methods: In order to study the dietary habits of the patients with type II diabetes 228 outpatients with type II diabetes referring to Ardabil Diabetic Clinic were randomly selected. Results : A common diabetic diet was reported by 87.8% of women (N = 115) and 77.1 % of men (N = 74). The dietary habits of the patients showed their awareness of limiting use of simple sugars. Use of foods with high simple sugars (e.g.: honey, jam, soft drink) were low among the patients. Potato was consumed by 58.8% of the female and 74.2% of the male, and of 43.8% of the subjects used mulberry with tea. Conclusions: Our result showed that there should be a greater focus on counseling, education and improving dietary of patients with diabetes.

Abstract
Background & Objectives: Elevated apolipoprotein B-100 and decreased Plasma HDL due to hypertriglyceridemia are common abnormalities in insulin-resistant subjects that increase the risk of cardiovascular disease. The aim of this study was to investigate the effects of 8 weeks progressive aerobic exercise (AE) on blood glucose, lipidand lipoprotein profile, and aerobic power in adults with type 2 diabetes. Methods: Twenty nine women with type 2 diabetes (mean age 43.4 ± 1.7 years and blood glucose range of 150 to 230 mg/dl ) were divided into a control (n=14) and exercise (n=15) groups. Exercise group participated in an aerobic training program 3 times per week for 8 weeks. The intensity of aerobic exercise was 60–75% of HR max. The control subjects were asked not to alter their physical activity patterns. All subjects underwent anthropometric, lipid profile and aerobic power evaluation, at the baseline and 48 hours after last session training. Following a 12 h overnight fasting, a venous blood sample was drawn for the analysis of total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), low-density lipoprotein (LDL), and (apoB100). Paired t test and analysis of covariance (ANCOVA) were used to analyze the data. Results: Significant improvement was observed in FBS, aerobic power, percent body fat, (Apo) B-100 and triglycerides (p< 0.05) for the exercise compared with the control group after training. No significant difference was observed in TC, LDL and HDL between two groups. Conclusion: According to our findings moderate intensity physical exercise can be effective in preventing the atherosclerosis via significant improvement in blood sugar, cardiovascular endurance, Apo B-100 and triglyceride in patients with type 2 diabetes.

Abstract
Background & objectives: Type II diabetes is a metabolic disorder accompanied with insulin resistance of the whole body cells and is considered be the fifth cause of death in the world. Adaptation to altitude can lead to tolerance to many diseases. Therefore, the aim of this study was to determine the effect of simulated intermittent altitude on the metabolic and hematologic parameters and liver function in streptozotocin induced diabetic rats.
Methods: In the current experimental study, twenty four male Wistar rats weighing 220±20 gr were randomly divided into three groups; normal control group (NC, n=8), diabetic control group (D, n=8) received fat diet for 2 weeks then were injected with streptozotocin (37 mg/kg) and diabetic+hypoxia group (D+H, n=8) including diabetic rat exposed to chronic intermittent hypoxia (PiO2≈106 mm Hg, simulated altitude≈3400 m, 14% oxygen for 8 weeks). Diabetic, hematologic and lipid parameters as well as ALT and AST activities were measured in peripheral blood.
Results: Our findings showed that intermittent hypoxia significantly decreased serum total cholesterol, LDL ,VLDL and triglyceride in D+H group compared to D group (p<0.05). Serum levels of fasting blood glucose and homeostatic model assessment-insulin resistance )HOMA-IR( index and ALT were decreased in D+H group vs. D group )p<0.05). Also, hemoglubin and hematocrite level increased in D+H group in comparison to D group )p<0.05). No significant difference was detected in red blood cell count in D+H vs. D group.
Conclusion: Based on resultant data, it seems that intermittent exposure to hypoxia (simulated to chronic and intermittent lodgement in altitude) can be used to control of type 2 diabetes by increasing hemoglobin, decreasing insulin resistance and improving liver function as well as lipid parameters.
