Abstract
Background: Hypoglycaemic effects of Galega officinalis and silver nanoparticles are established. In the present study, the effects of silver nanoparticles synthetized by Galega officinalis extract were investigated on gene expression of TNF-α, IL-6 and serum levels of liver enzymes in diabetes type 2.
Methods: In the present study 20 male Wistar rats in 4 group(n= 5 in each group) weighing 180- 200 gr were used. Control or nikotinamid and stroptozotosin induced diabetic rats receieved intraperitoneal injection of saline or 2/5mg/Kg silver nanoparticles synthetized by Galega officinalis extract or chemichal method for 14 days respectively. One day after the last injections, serum samples and adipose tissue were collected. Mean serum concentration of glucose, urea, creatinine, alanine amino transferase(ALT), and aspartate amino transferase(AST) were determined by spectrophotometry. Mean relative gene expression of TNF-α and IL-6 were determined by method of real time PCR.
Results: Mean serum levels of ALT and AST enzymes, glucose, urea significantly decreased in diabetic rats receiving chemichal or green silver naoparticles compared to diabetic group. Mean relative gene expression of TNF-α and IL-6 significantly decreased in diabetic rats receiving chemichal or green silver naoparticles compared to diabetic ones.
Conclusion: Both chemical and green synthetized silver nanoparticles may prevent hepatocyes damages and they may improve insulin resistance in diabetes type 2 partly via decresing pro- inflammatory factors.

Abstract
Background: Over the years type 2 diabetes, in addition to causing irreversible effects on various parts of the body, also causes liver dysfunction and increases the risk of heart failure, but due to the lack of physical symptoms, less attention has been paid. So, the aim of this study was to determine the effect of 8 weeks of endurance training on diabetic indexes and myocardial GLUT4 and liver enzymes of type 2 diabetic rats.
Methods: A total number of 24 rats (220±20) were divided randomly into three groups; 1-Non-diabetic Control group (NC, n=8). 2-Diabetic Control group (D, n=8) To induce type 2 diabetes, high-fat diets were given to rats for two weeks, then streptozotocin (Aldrich company) at a dose of 37 mg / kg in citrate buffer M0.1 (PH4.5) after 6 hours of intraperitoneal fasting was injected, For the healthy control group, the same amount of buffer was injected. Also, aerobic exercise groups ran 5 times a week and 8 weeks on a motorized treadmill. Diabetic index’s, myocardial GLUT4 (Western blotting) and liver enzymes (ELISA) of rats were measured.
Results: Endurance training significantly decreased fasting blood glucose, insulin resistance index (both P= 0.00). It also caused a significant increase in insulin (P= 0.01) and insulin sensitivity index (P= 0.00) compared to the diabetic control group. On the other hand, the amount of GLUT4 in the training group increased significantly (P= 0.01). The results also showed that in comparison with the diabetic control group, ALT and AST did not increase significantly in diabetics with endurance training (P= 0.30, P= 0.5, respectively).
Conclusion: Based on the results, it seems that endurance training significantly increases the level of GLUT4 in the heart and significantly decreased diabetic parameters such as fasting glucose, HOMA-IR index and liver enzymes.

Abstract
Background: The health and proper functioning of the endoplasmic reticulum in the liver can lead to an increase in the quality of the metabolism of liver cells. Exercise can lead to liver health by regulating liver enzymes and factors related to apoptosis pathway. Therefore, the aim of the current research is to compare the performance of the endoplasmic reticulum chaperone protein of the liver of healthy model rats with the intervention of different training sessions and starvation.
Methods: In this experimental research, 30 Wistar male rats with a weight range of 330 ± 25 grams were selected and divided into six groups: 1) control, 2) starvation, 3) 3 days of training per week, 4) 5 days of training per week, 5) starvation + 3 training days per week, 6) starvation + 5 training days per week. Training consisted of one hour of continuous running on a treadmill for 4 weeks, and starvation was performed for 14 hours when the rats were awake. Data analysis was performed using one-way analysis of variance and post hoc LSD statistical tests in SPSS version 23 software. A significance level of P≤ 0.05 was considered.
Results: Data analysis showed a significant change in the levels of liver enzymes alanine aminotransferase (ALT) and aspartate transaminase (AST) (P≤ 0.05). This change in CHOP gene expression was also significant (P≤ 0.05).
Conclusion: Aerobic training for 3 and 5 days with starvation can lead to liver health by reducing liver enzymes (AST and ALT) and cell death-related factor (CHOP) through the apoptosis pathway.
