Effect of magnesium pre-treatment on alloxan induced hyperglycemia in rats

Background: The role of vitamins and mineral supplementation in the prevention of diabetes mellitus is not well elucidated. Objective: The effect of prior administration of magnesium on alloxan induced diabetes was assessed in rats. Methods: 36 Male albino rats were used for this study. The animals were divided into 6 groups of 6 animals each; group 1 was healthy control; groups 2 served as diabetic control. Animals in group 3 received magnesium (100 mg/kg) i.p one hour prior to alloxan (120 mg/kg) administration, group 4 were also received magnesium (150 mg/kg) i.p one hour prior to alloxan administration. Animals in group 5 received magnesium (100 mg/kg) i.p only; group 6 animals received magnesium (150 mg/kg) i.p only. Blood samples were obtained from all animals and plasma glucose levels were determined on Day 0 (prior to treatment), Day 2, Day 5, Day 7 and Day 10 after the commencement of treatment. Results: There was significant increase (P
