اثر عصاره هیدرو الکلی آلوئه‌ورا برقند خون، انسولین سرمی و آنزیم های کلیدی مسیرهای متابولیسمی گلیکولیز و گلوکونئوژنز در سلول‌های کبدی موش‌های صحرایی دیابتی نوع 1

Background and Objective: Recently, it is considered the role of hypoglycemic agents specially medicinal plants derivatives in treatment of diabetes mellitus. Aloe Vera contains phenolic compounds and flavonoids with antioxidant properties that reduces the complications of the disease.The aim of study was to investigate the effects of hydroalcoholic extract of Aloe Vera in serum levels of glucose and insulin and key enzymes in metabolic pathways of glycolysis and gluconeogenesis in streptozotocin-induced diabetic Wistar rats. Materials and Methods: A total of 50 rats (initial weight of 220 ±10 g) were divided into five groups. Two months after treatment with Aloe Vera extract, the rats were sacrificed and blood glucose and serum insulin levels were measured. It was also isolated the liver then, extracted mRNA from it, expression levels of Glucokinase and Phosphoenol pyruvate carboxy kinase enzymes were measured by Real Time PCR. Results: The results showed that the extract of Aloe Vera at doses of 100, 200 and 400 mg/kg increase insulin secretion (p<0.05), hypoglycemia (p<0.001), increasing expression of Glucokinase enzyme (p<0.05) and reducing  expression of the Phosphoenol pyruvate carboxy kinase enzyme (p<0.05) in diabetic rats. Conclusion: Not only dose Aloe Vera hydroalcoholic extract influence on insulin secretion, it also affects on key enzymes gene expression of Glycolysis and Gluconeogenesis pathways. Hence, this extract can be effective for improvement of diabetic complications.
