اثر عصاره آبی گیاه صبر زرد (Aloe vera) برقند و چربی های خون در موش‌های صحرایی نر دیابتی

Background: Aloe vera is a herbal plant being used as an anti-inflammatory agent, burning recovery as well as immune system boosting agent. The aim of this study was to evaluate the effects of Aloe vera on blood glucose , lipids and lipoproteins in streptozotocin-induced diabetic male rats. Methods: This study was carried out on 56 male rats, weighing 150-200 gr. Animals are divided into 7 groups (one control and six test groups). Diabetes were induced in test groups via streptozocin (65mg/ kg-IP). After a week, blood samples analyses for FBS. All diabetic groups, except the control one, were taken 100,200,300,400 mg/kg Aloe vera extract and 5mg/kg glibenclamid by gavages for a period of 4 weeks, respectively. After this period fasting blood samples were collected from all groups.Results:The results showed that the FBS decreased in groups that received 400mg/kg and glibenclamid (respectively,162/62±23.12and193.37±26.51). In addition, 3-6 groups showed decrease TG and Cholesterol level in comparison with those of control groups. In all groups which received Aloe vera and glibenclamid, LDL level were significantly decreased in comparison with control groups but HDL level had no change. Conclusion: The results of this research indicate that Aloe vera aqueous extract lead to decreased Blood glucose, Cholesterol, LDL and TG levels. Further studies is suggested for exact mechanism of Aloe vera in diabetic rats.
