Background: The importance of feed controlling has been proved in metabolic control of diabetic patients. An appropriate metabolic control prevents later complications. Patients with diabetes mellitus are deprived from eating sweat foods. Considering the effect of different carbohydrates on blood sugar, physicians and patients confront a lot of questions about eating these foods. The aim of this study was to compare the effect of sugar cube and Date consumption on blood sugar in patients with type 1 diabetes.
Methods: As a clinical-trial, we selected 20 patients with type I diabetes mellitus sequentially. They were divided into two groups with 10 subjects in each group. The patient’s blood sugar was measured in 2 days with one week interval, before and after eating a Date (10gr) and a sugar cube (5gr). We measured blood sugar at 30, 60, 90 and 120 minutes after consumption. Data analysis was performed by SPSS software version 11, and the results were compared by paired t test.
Results: There was no significant difference between the blood sugar after eating Date and sugar cube. We also compared the surface under the curve of blood sugar after eating date and sugar cube in 2 hours, which was 1619.4 ± 614 mg.min/dL and 1572 ± 967 mg.min/dL for sugar cube and Date respectively, which the difference was not significant.
Conclusion: Rising in blood sugar after Date consumption has not significant difference in comparison with sugar cube consumption in patients with type I diabetes. So, eating Date in diabetic patients is not preferable to eating sugar cube.

Background: Mitochondria is one of the intracellular organelle with specific DNA. Some diseases caused by mtDNA mutations have been reported up to now. Mutation of A3243G and deletion of 5kb are two of them that related to Diabetes type II. The aim of this study was to evaluate the frequency of A3243G mutation and 5kb mt DNA deletion in type II diabetic patients.
Methods: The DNA extracted from blood of 130 patients with diabetes type II. Serum insulin of the patients were also measured. Sequence assigning, PCR – RFLP and SSCP methods were used to detect the A3243G or other mutation in mitochondrial tRNA (leu) gene. Standard and multiplex PCR were used to detect 5kb deletion in patient’s mt DNA and were compared with 40 healthy persons.
Results :We couldn’t identify any deletion of 5kb or A3243G point mutation in our patients but SSCP results showed new pattern of PCR Product in patients. An “A” nucleotide deletion in A 3314 position was detected in mitochondrial ND1 gene in 6 patients. So far this point deletion has not been reported.
Conclusion: Identification of the mitochondrial gene mutations helps to preclinical diagnosis of diabetes type 2. More research is necessary in this field.

Background: Several studies and research have shown a higher prevalence of celiac disease (CD) and elevation of serum antibody (AGA-IgA & IgA-tTG & EMA-IgA ) in patient with diabetes mellitus type I (T1DM) in versus general and non-diabetic population. Thus screening of CD is recommended in T1DM). This study was conducted to compare frequency of celiac disease in patients with T1DM and healthy persons.
Methods: As a case-control study,60 patient with T1DM that reffered to endocrine clinic of Qazvin’s Boo-Ali hospital , in nearly one year period were enrolled as case group. 60 non-diabetic healthy subjects with age and sex matched, were selected as control group. Blood levels of Total IgA, AGA-IgA and IgA-tTG were measured in all of them, subjects who had elevated of both AGA-IgA and IgA-tTG underwent an upper GI endoscopy and biopsy was done from distal part of duodenum.
Results: Any one in case group hadn't IgA deficiency. 14 subjects in control and 12 subjects in case group had positive AGA-IgA that there was no significant difference between them . 2 subject of case group had positive IgA-tTG. Duodenal biopsy in 1 of 14 cases who had elevated AGA-IgA )1 of 2 cases who had elevated IgA-tTG) , revealed total villous atrophy indicating CD (Type IIIC with revised Marsh criteria 2001) and in other cases pathologic findings were normal or with nonspecific changes.
Conclusion: Frequency of CD in T1DM in our study is 1.67%. There is not any significant difference between case and control groups in prevalence of Celiac disease . But we conclused that screening with AGA-IgA is not a reliable screening test for CD , because there is not significant difference between T1DM and general population .

Background: Usually excess feeding in stored in the body as fat and leads to overweight. One of the causes of catching type 2 diabetes is obesity. Proinflammatory cytokines such as TNF- α and IFNγ can damageTnf- Α And Ifnγ By Peripheral Blood Mononuclear Cells Of Patients With Diabetes Mellitus Type Ii Admitted To Ganjavian Dezful Hospit insulin signaling in insulin-sensitive tissues. In this study, the effect of garlic extract on the expression of TNF-α and IFNγ secreted by the mononuclear cells was measured.
Methods: After taking peripheral blood from patient with type 2 diabetes, mononuclear cells were extracted by Ficoll Method. Cells were a culture with two different concentration of garlic extract (10% and 30%) for 48 and 24 hours. Then for measuring TNF-α and IFNγ release level, ELISA method was used.
Results: Garlic extract can reduce the amount of TNF-α secretion from cells mononuclear, although the timing and concentration of the extract had no effect on the results. Moreover, garlic extract had no effect on the secretion of IFNγ.
Conclusion: Using garlic extract can be adopted therapeutic strategies aimed at adipose tissue inflammation and insulin resistance that is useful for the prevention and treatment of type 2 diabetes.
