Abstract
Background: Chronic complications of diabetes causes substantial mortality and morbidity. The incidence and rate of progression of these complications depends on ethnic factors. The aim of this study was to investigate the incidence of late complications of diabetes and its relation to blood glucose control in a group of diabetic patients from South of Iran.
Methods: In this retrospective study, medical records of all diabetic patients who were followed regularly during a 12 year period at outpatient clinics of Shiraz University of Medical Sciences were investigated. Information regarding age, sex, type of diabetes, duration of disease , mean fasting and postprandial blood sugar, complications (eye, kidneys, peripheral nerves, foot, cardiovascular, cerebrovascular), and timing of complications with regard to duration of disease were collected.
Results: The study population included 392 patients (205 males and 186 females), 300 patients had type 2 and 92 had type 1 diabetes. The mean age at diagnosis was 20.412.8 years for type 1 and 47.510.4 years for type 2 patients. 95% of patients developed at least one chronic complication during the follow-up period. The incidence rates of eye , renal, and peripheral nerve complications were 51.5, 44.7, and 68.8 percent respectively. Diabetic foot problems occurred in 16.8 percent of cases and it led to amputation in 8.4 percent (33 cases) of patients. The incidence rates of cardiovascular and cerebrovascular complications were 49.7 and 15.3 percent respectively. The development of eye, renal, and peripheral nerve complications was related to blood sugar control.
Conclusion: Our diabetic patients developed chronic complications early and at a higher than expected rates. Future studies and more emphasis on prevention methods are recommended.

Abstract
Background: Previous in vitro and animal studies have supported a role for growth hormone in development of diabetic nephropathy. The purpose of this study was to investigate the relation between basal and stimulated growth hormone and proteinuria in type 2 diabetic patients.
Methods: 21 type 2 diabetic patients with macroalbuminuria were selected. Fasting insulin, basal and levodopa stimulated growth hormone levels were measured. The control group consisted of 21 type 2 diabetic patients with 24 hr urine protein of less than 50 mg. The two groups were matched according to sex, age, duration of diabetes, body mass index, creatinine clearance, fasting blood sugar, glycosylated hemoglobin, and blood pressure.
Results: The patients with macroalbuminuria had higher basal growth hormone (3.1 2.6 vs 1.25 0.7 ng/ml, P = 0.024). Stimulated growth hormone and fasting insulin levels were not significantly different.
Conclusion: There is direct relation between basal growth hormone and development of diabetic nephropathy and this relation suggests a role for growth hormone in human diabetic nephropathy.

Abstract
Background: Diabetes mellitus is the most common cause of renal failure, blindness, non- traumatic amputation and neuropathy. Homocysteine, a sulfurated amino acid, has a close correlation with Methionine and Cysteine. The conversion of Methionine to Homocysteine and Cysteine is required coenzymes like vitamin B6, B12 and Folate. The effect of Metformin on serum Homocysteine level by decreasing vitamin B12 level in patients with type 2 diabetes mellitus was described previously. Methods: This is a prospective clinical trail study among patients with type 2 diabetes mellitus in Shiraz. 76 patients were divided into two groups (38 patients in each group). First group treated with Metformin 500-2000 mg/day and the second group treated with Glibenclamide 5-20 mg/day with follow up period of at least 6 months. Hb and MCV were used in follow up to detect megaloblastic anemia, indicator of B12 and folate deficiency. Fasting plasma Homocysteine level Hb A1C and blood sugar were measured in baseline and at 3 and 6 months follow up periods.
Results: There was no significant difference between age, sex, weight, height and BMI and baseline serum profile between the two groups. Homocysteine level increased significantly in Metformin group at 3 and 6 months(P=0.003 and 0.001 respectively). Mean plasma homocysteine level after 6 months were 10.98±0.58 μmol/l in Metformin and 10.0± 0.88 μmol/l in Glibenclamide group, with significant difference between the two groups (P=0.001).
Conclusion: Metformin increases the plasma Homocysteine level. Metformin will accumulate highly in gastrointestinal wall and cause malabsorption of vitamin B12, therefore we can conclude that the use of Metformin for 6 months can cause vitamin B12 malabsorption and increase in plasma homocysteine level. Increase in plasma homocysteine level was 7.54% in our study that is higher in comparing to the other studies. It can be explained by longer duration of Metformin therapy in our study. Rising in Homocysteine levels may have detrimental effect on vessels that need further study.

Abstract
Background: Single nucleotide polymorphisms of Adiponectin gene have been associated with BMI, insulin sensitivity and type 2 diabetes, reportedly. In present study we performed a genetic association study for Adiponectin gene at position +45*T/G in type 2 diabetes and normal subjects of Tehran population.
Methods: Diabetic patients were selected from diabetes clinic and normal healthy control subjects aged between 25-64 years selected from zone 17 of Tehran. Adiponectin gene polymorphism was analyzed using PCR-RFLP method in normal healthy controls (N=70), obese diabetic patients (N=80) and non-obese diabetic patients (N=72).
Results: Frequency of TT genotype was 62.5% in non-obese diabetic patients and 78% in control group, that was statistically significant (TT vs TG+GG: P=0.02, OR=2.2, CI:0.98-5.00). There was also a significant difference for allele T and G frequencies when we compared between non-obese diabetic patients and controls group. The frequency of allele G was increased in non-obese diabetic (20.1%) patients compared to controls (12%) (P: 0.04 OR: 1.8 CI: 0.9-3.7).
Conclusion: This study showed TG and GG alleles of Adiponectin gene polymorphism at position +45*T/G are risk factors for development of diabetes mellitus while this effect is independent from BMI and obesity.

Abstract
Background: Type 2 diabetes mellitus is the most common type of diabetes which is triggered by various factors such as obesity, hyperlipidemia, hypertension, dietary habits and inheritance. With respect to geographic variation of diabetes prevalence, it is important to know the risk factors regionally.
Methods: As a case-control study, we looked for important risk factors of diabetes in our region. This study consisted of 400 individuals in case group and 400 individuals in control group. All these anthropometric measurements were calculated by standard methods. Blood samples taken from two groups were studied for TG, FBS, Cholesterol and HbA1c. Data are reported as the Mean±SD. P<0.05 was considered as statistically significant.
Results: There was no significant difference between two groups about mean age and sex ratio. Statistically significant difference were found for central obesity, hyperlipidemia, hypertension, polycystic ovarian syndrome (PCOS) and positive family history of diabetes in both groups (P<0.05).
Conclusion: The results showed that central obesity, hyperlipidemia, hypertension, PCOS and positive family history of diabetes are important risk factors of diabetes mellitus in Shiraz. In concordance with the results of this study, screening programme for that risk factor of diabetes in this region is suggested.

Abstract
Background: The relationship between diabetes and serum insulin and Zinc (Zn) levels is complex with no clear cause and effect relationships. Since Zn plays a clear role in the synthesis, storage and secretion of insulin as well as conformational integrity of insulin in the hexametric form, the decreased Zn, which affects the ability of the islet cell to produce and secrete insulin, might then compound the problem, particularly in type 2 diabetes. The aim of this study was to determine the changes of plasma Zn in patients with type 2 diabetes mellitus and healthy control in Shiraz city.
Methods: As a case-control study, we determined the serum Zn levels by atomic absorption spectrophotometer, blood HbA1c levels with columnar chromatographic method and Glucose, by enzymatic colorimetric method in auto analyzer. Data are reported as the Mean±SD and P<0.05 was considered as statistically significant
Results: Results of this study revealed that levels of Zn in serum of diabetic patients is lower than in the healthy control in Shiraz city (P<0.05).
Conclusion: With respect to the result of this study, dietary educations about consuming enriched Zn foods such as sea foods and corn in diabetic patients is necessitated.

Abstract
Background: The purpose of this study was to compare three intensities of acute aerobic exercise on plasma visfatin concentration in type 2 diabetic males. Methods: Ten men with type 2 diabetes (mean ± SD age 52.6 ± 3.6 years, height 171.3 ± 6.7 cm, Weight 87.58 ± 4.7 kg) participated in the study. In the first session, anthropometric measurements, body composition, and peak oxygen uptake (VO2peak) was measured in all subjects. In the next sessions, subjects completed three acute aerobic exercises on separate days in a crossover design. The three exercise trials performed at intensity of 40%, 60%, and 80% VO2peak after fasting for at least 10 hours. Energy expenditure was 300 kcal for each exercise trial. Blood samples before exercise, immediately after and 24 hours after exercise were collected for measuring visfatin, glucose and insulin. Results: The results showed no significance interaction (p>0.05) between exercise and sampling time. This analysis also revealed significance in the main effects (p>0.05) of the two factors (exercise and sampling time). Pearson correlation showed that there was significant relationship between visfatin and insulin (p<0.05). Conclusion: According to the present results, we can conclude that acute aerobic exercise at different intensities with 300 kcal energy expenditure will not change visfatin levels in type 2 diabetes.

Abstract
Background: Evidences exist that abdominal obesity is a difference in terms of body mass index (BMI) and these two factors have different effects on bone density. This study examined the association between body mass index, obesity, the history of fracture and bone mineral density in Iranian population. There exist evidences on the effects of body mass index (BMI) and abdominal obesity, and the role of this two factor on bone density. This study examined the association between body mass index, abdominal obesity, and the frequency of fracture with bone mineral density in Iranian population Methods: The Study was done as a cross-sectional, population-based retrospective study. People over 18 years were included in the third part of the IMOS project (National comprehensive plan for the prevention, diagnosis and treatment of osteoporosis). Abdominal obesity was calculated based on waist to hip ratio that was considered positive > 0.95 in men and 0.85 in women. The linear regression test was used to examine the relationship between BMI and abdominal obesity with bone densitometry. Results: A total 2019 cases (717 men, 1302 women) with 41.85 ± 13.95 years enrolled in this study. Almost, 36% of men and women were obese based on waist circumference. Correlation coefficients of BMI with bone density were equal 0.236 for Hip, 0.133 for femoral neck, 0.138 for lumbar spine. Waist to hip ratio was inversely associated with bone density. Bone densities in the hip and lumbar spine, in individuals with a positive history of wrist fracture were significantly lower than those with a negative history of fracture. Conclusion: contrary to the total body fat, abdominal obesity based on waist to hip ratio is inversely associated with bone density. In other words, abdominal obesity increases the risk of fractures by reducing the bone density without creating protective shield of adipose tissue in vulnerable areas.

Abstract
visfatin secreted by various factors, including cytokines such as TNF-α and IL-6 is affected. The purpose of this study was to evaluate the effect of eight weeks of combined training (resistance circular - aerobic) visfatin concentration, IL-6 and TNF-α in obese men with type II diabetes.
Methods: The population of the research was all men with diabetes type II in District 2 of Ahwaz. Twenty four patients with diabetes type II, aged 40-55 years and fasting blood glucose lower than 200 mg /dl were selected by purposive sampling. First, the anthropometric variables and body composition were measured, then subjects were randomly divided into two groups (experimental, n=12 and control, n=12). Combined exercise training was done for 8 weeks (5 days/week, 30 to 50 minutes) for experimental group. To analyze the changes in the covariance analysis and dependent t test measured variables at a significance level of p≤05.
Result: After eight-week combined exercise training, fasting blood glucose and plasma visfatin significantly decreased p≤05. But no significant changes were observed in the levels of IL-6 and TNF-α p≥05. Also, the inverse relationship between plasma visfatin with IL-6 and TNF-α was observed (P≤ 0.05).
Conclusion: Eight weeks of combined training despite a positive effect on plasma visfatin, due to no significant changes in plasma IL-6 and TNF-α in patients with type 2 diabetes, it seems this type of exercise in reducing obesity and visceral fat and thereby reducing plasma visfatin is appropriate, but the potential change in IL-6 and TNF-α does.

Abstract
Background: The release of adipokines from adipose tissue depots plays a key role in regulating metabolic homeostasis and several other physiological processes, including diabetes, obesity, and vascular diseases. This study investigated the effect of eight weeks of high intensity interval training (HIIT) on asprosin, lipid profile and insulin resistance in type 2 diabetic male rats.
Methods: 24 male Sprague Dawley rats were randomly divided into four equal groups: control (C), control traning (C+T), diabet (D) and diabet traning (D+T). Diabetes was induced by the combined method of high fat diet and low dose strepotozocin injection. The traning group performed the HIIT program on the treadmill for eight weeks. Data were analyzed using one-way ANOVA and bonferroni post hoc test at a significance level of P<0.05.
Results: The results showed increased plasma asprosin in D group compared to C (P=0.0001) and decreased in C+T group compared to C (P=0.03) and D+T group compared to D (P=0.04). There was no significant difference in HOMA-IR between the C and C+T group (P=0.9) but decreased in D+T compared to D (P=0.0001). HDL increased in D+T group compared to the D (P=0.0001) and decreased TG and LDL (P=0.001). There was no significant difference between TG and LDL in the C group compared to the C+T, but HDL increased in C+T (P=0.01).
Conclusion: Plasma asprosin increases in rats with type 2 diabetes and HIIT can reduce the complications of diabetes by improved lipid profile and reduce asprosin and insulin resistance.
