Abstract
Background: Diabetes is a kind of metabolic disorder characterized by hyperglycemia, caused by defect in insulin function, secretion or both. In chronic hyperglycemia different tissues and organs, such as thyroid gland underwent histophysiological alterations. The aim of the present study was to compare the effects of type 1 and type 2diabetes on the serum levels of biochemical factors and histological changes in the thyroid gland in male Wistar rats.
Methods: After induction of type 1 diabetes (Alloxan 135 mg/kg BW) and type 2diabetes (10% fructose administrated through drinking water for 8 weeks) all rats were kept for 2 months. Blood samples were collected at the beginning and in the middle and at the end of experiment for biochemical factors analysis. After that, the thyroid gland of all rats were removed and processed for histological preparation. Then the HE stained sections were examined for thyroid gland volume and follicular surface density measurements, using Cavalieri’s Principle and stereological method, respectively.
Results:The results showed an increase in surface density and a decrease in thyroid volume in type 1 diabetic and type 2 diabetic groups, when compared with control. Furthermore, in type 1 diabetic group, the Triglycerid and Cholesterol levels increased and LDL level decreased, while in type 2 diabetic group, LDL and HDL levels slightly decreased. These results reveal that type 1 and type 2 diabetic conditions probably cause hypo- and hyper activity of thyroid gland, respectively.

Abstract
Background: During recent decades, physical activity has become a key auxiliary tool in controlling many diseases, including diabetes. The aim of this study was to investigate the effect of 8 weeks of resistance training on the plasma levels of preptin and endothelin 1 in men with type 2 diabetes.
Methods: The current research is semi-experimental. The statistical sample of this study consisted of 38 men with type 2 diabetes, who were randomly divided into two groups of 19 experimental and control. Subjects in the experimental group performed 8 weeks of resistance training three sessions a week with moderate intensity. 24 hours before and after 8 weeks of training, plasma levels of preptin, endothelin 1, and indicators related to type 2 diabetes were measured by the ELISA method. Correlated t-tests and independent t-tests were used to examine intra-group changes. SPSS software was used to analyze the data (P≥ 0.05).
Results: Correlated t results showed that plasma levels of preptin and insulin resistance index (P= 0.001) as well as plasma endothelin 1 (P= 0.001) decreased significantly in the post-test compared to the pre-test of the experimental group. has been found Also, the independent t-test results showed that the plasma levels of preptin, insulin resistance index (P= 0.001) and endothelin 1 (P= 0.002) were significantly lower in the post-test of the experimental group compared to the control.
Conclusion: According to the obtained results, it seems that doing resistance exercises improves glucose sensitivity by reducing preptin and reducing the possibility of blood pressure by reducing endothelin 1 in preople with type 2 diabetes.

Abstract
Background: Under hyperglycemic conditions, inflammatory processes with damage to the peripheral nerves are involved in the occurrence of neuropathy. This study aimed to compare the anti-inflammatory effects of metformin (synthetic drug) with gallic acid (natural compound) in hyperglycemic conditions.
Methods: Hyperglycemia was induced in male rats by the intraperitoneal injection of Streptozotocin (STZ) at a dose of 60 mg/Kg. For this research, rats were divided into four groups. Two groups were healthy control and hyperglycemic control rats that did not receive any drugs. The other two groups were hyperglycemic rats, which respectively received Metformin at a dose of 300 mg/kg/day and gallic acid at a dose of 40 mg/kg/day. At the end of the 8-week period, the rats in all groups were anesthetized and a sample of their sciatic nerve was taken to measure the expression level of genes related to pro-inflammatory cytokines IL-6, IL-1β and TNF-α. Data analysis was done by SPSS software and comparison between average data was done by one-way ANOVA and Tukey's post hoc test.
Results: Induction of hyperglycemic conditions in rats increased the expression of genes related to pro-inflammatory cytokines IL-6 (p=0/000), IL-1β (p=0/008) and TNF-α (p=0/005). However, administration of metformin and gallic acid to hyperglycemic rats for 8 weeks reduced the expression of IL-6, IL-1β and TNF-α genes (p˂0.05).
Conclusion: Gallic acid, like metformin, with its anti-inflammatory properties, can be effective in improving complications caused by hyperglycemic conditions, especially neuroinflammation, and it is hoped that it will be clinically useful for diabetic patients in the future.
