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: 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.
