Abstract
Background: Atherosclerotic complications are one the most common causes of death in patients with type 2 diabetes mellitus. Epidemiological data indicate that the consumption of omega-3 unsaturated fatty acids (O3FA) leads to a reduction in cardiovascular disorders. The metabolic effect of this substance in patients with type 2 diabetes is still a matter of debate, however. The aim of this study was to assess the metabolic effect of O3FA in Iranian diabetic patients.
Methods: 50 diabetic patients (20 men and 30 women mean age 49±7.3 years) were randomly allocated to either the intervention (diet + fish oil containing O3FA) or the control group (diet alone). The lipid and glucose levels, blood pressure, and weight of each patient were measured at the beginning of the study. The duration of the study was 3 months. The aforementioned parameters were re-assessed at the end of the study.
Results: O3FA consumption was associated with a significant reduction in serum triglyceride levels (p<0.001). Reductions in weight, fasting blood sugar, and glycosylated haemoglobin were noted in the intervention group but were not statistically significant. No changes occurred in total cholesterol, HDL, and LDL levels. The dosage of oral hypoglycaemic agents was unchanged in both groups throughout the study.
Conclusion: O3FA may be recommended for the management of hypertriglyceridaemia.

Abstract
Background: The non-enzymatic glycosylation (NEG) of proteins in diabetes damages both the structure and function of these proteins. In vivo and in vitro studies have shown that NEG of proteins and advanced glycosylation end-products (AGE) contribute to the pathogenesis of both macrovascular, such as atherosclerosis, and microvascular complications, such as retinopathy and nephropathy, in diabetes.
Methods: We studied the electrophoretic mobility, fluorescence at isoelectric pH, and time-dependent AGE formation of glycosylated albumin. For the first time, we have used isoelectric focusing to study serum glycosylated albumin in diabetic patients and healthy controls. Results: After 10 weeks incubation with glucose, the electrophoretic mobility of glycosylated albumin increased 21.3% compared with normal albumin. The isoelectric pH of albumin decreased from 4.6 on day 1 to 4.1 on day 7. The increase in electrophoretic mobility was accompanied by the drop in pH during the first week of incubation. These changes correlated well with those observed by fluorescence. The glucose content of the albumin samples decreased during the first week of incubation, but gradually increased thereafter. Fluorescence readings agreed with these observations. Using isoelectric focusing, there was a significant difference between the serum albumin of diabetic and normal individuals (p<0.001).
Conclusion: Increased electrophoretic mobility during the first week with a simultaneous decline in isoelectric pH shows that AGE formation begins after the first week. The reduction in glucose concentration during the first week and its subsequent increase during the second week may be attributed to the formation and hydrolysis of AGE. This method may be used to determine the stability or progress of diabetes.

Abstract
Background: Metabolic syndrome is a cluster of disorders which altogether increase the risk of cardiovascular disease and type 2 Diabetes. We evaluated the effect of consumption of Omega-3 Fatty Acids on different components of this syndrome.
Methods: This was a double blind placebo controlled clinical trial on 199 elderly residents of Kahrizak charity foundation in Tehran. Participants were divided into two groups of intervention and control, consisting of 100 and 99 persons, respectively. The intervention group was given the Omega-3 Fatty Acid capsules contain 180 mg EPA and 120 mg DHA once daily. The control group was given placebo once per day. The duration of the study was 6 months in the beginning and after 6 months of the study, blood pressure, waist circumference and Serum levels of ESR, hs-CRP, APO B, APO A1 and Insulin were measured.
Results: The study was completed in 89 and 87 participants in the intervention and control groups, respectively. The mean age of intervention and control groups were 74.13 ± 9.96 and 75.17 ± 8.70 years, respectively. Consumption of Omega-3 Fatty Acids could decrease diastolic blood pressure (P = 0.001) and serum Triglyceride levels (P = 0.01) significantly compared to control group. No change was observed in other measured parameters.
Conclusion: Consumption of Omega-3 Fatty Acids with dosage used in this study could probably improve symptoms of Metabolic syndrome in the elderly.

Abstract
Background: Type 2 diabetes is a major metabolic disorder. This study was aimed to evaluate the effect of probiotic soymilk fermented with Bifidobacterium lactis and containing omega-3 on hematologic, oxidative stress, anti-oxidant and inflammatory parameters in type 2 diabetic rats.
Methods: In this experimental manipulation study 65 rats were divided into five groups. Type 2 diabetes was induced by a single injection of streptozotocin and nicotinamide. Normal control (NC) and diabetic control (DC) rats received 1 mL/day of distilled water, and three groups of diabetic rats were administered 1 mL/day of soymilk (SM), fermented soymilk (FSM) and fermented soymilk fortified with omega-3 (FSM+omega-3) products by oral gavage for 28 days. Hematologic, oxidative stress, anti-oxidant and inflammatory parameters were measured at the end of experiment.
Results: At the end of experiment, in all treated diabetic rats compared with the DC group, red blood cell (RBC), hemoglobin (Hb), hematocrit and superoxide dismutase (SOD) concentrations increased significantly (p<0.05), and malondialdehyde (MDA) concentrations reduced significantly (p<0.05). The reduction of MDA and increasing in Hb, RBC, hematocrit and SOD concentrations in the FSM+omega-3 group was more than two other groups. In the FSM+omega-3 group, high sensitivity C-reactive protein (hs-CRP) concentrations compared with the DC and FSM groups were significantly lower (p<0.05).
Conclusion: The experiments suggest that combining soymilk, probiotics and omega-3 may be beneficial for the reducing oxidative-stress in type 2 diabetes.
