Abstract
Background: Alloxan is on of the xenobiotic agents which is classified as diabetogenic materials. Magnesium is an important cofactor regulating the activity of carbohydrate enzymes and lipid synthesis. In this study the contrasting effects of Alloxan and magnesium on plasma free fatty acids (FFA) in rats was investigated.
Methods: Male mature rats were used as test models for the diabetes induction. 28 rats received Alloxan (120mg/kg) intraperitoneally and plasma glucose level measurement after 72 hours demonstrated diabetes induction.
Results: The results were compared to the control groups, and confirmed the presence of diabetes in rats. Analysis of plasma FFA showed a significant increase (751.25 mM), compared to the control group (286.68 mM). In contrast, Measurement of red blood cell (RBC) Magnesium showed a significant decrease from 7.18 mg/dL in control group to 4.89 mg/dL in diabetic rats.
Conclusion: The results of this study showed that in diabetic condition, there was an inverse relationship between plasma FFA and RBC Magnesium. Therefore, these data suggest that analysis of the effects of Magnesium upon induction of diabetic condition could provide important information for management of diabetes.

Abstract
Background: Diabetes can disrupt the balance of cell death through different cell pathways, and exercise or consumption supplements can be effective in maintaining the balance of cell death types; Therefore, the purpose of this research is the effect of magnesium supplementation and exercise training on the content of CREB2 and C/EBP homologous protein (CHOP) in the left ventricle of the heart of type 2 diabetic rats.
Methods: In this experimental study, 24 2-month-old male Sprague-Dawley rats with an average weight of 280±20 grams were selected. Type 2 diabetes was induced by injecting nicotinamide and streptozotocin solutions. The rats were randomly divided into four groups, 1) control, 2) supplement, 3) training and 4) training+supplement; Resistance training consisted of 8 weeks and 3 weekly sessions of climbing a ladder. Magnesium supplement was given to rats once a day. To analyze the data, one-way ANOVA and Tukey's post hoc tests were used in SPSS version 29.
Results: Eight weeks of magnesium supplementation and resistance training led to a significant change in the content of CREB2 and CHOP proteins between groups in the left ventricle of the heart (P= 0.001). A significant decrease was observed in the groups of resistance training + magnesium supplement and magnesium supplement compared to the control group (P≥ 0.05); But the resistance training group had increased compared to the control group (P≥ 0.05).
Conclusion: The increase and decrease of CREB2 and CHOP proteins in the left ventricle of the heart can lead to improvement and physiological adaptation, like a bilateral mechanism.
