Abstract:
Objective To investigate the therapeutic effect and its mechanism of pathogenicity of streptozotocin diseased rats treated by the mixture of kelp extract, wolfberry, and Chinese yam. Methods Streptozotocin-diabetic rat model were taken the mixture of kelp extract, wolfberry and Chinese yam with the ratio of 1:1:1 by intragastric administration. positive control group was fed metformin of 83.5mg/kg, the control group and the model group were given the same amount of distilled water. The safety of high dose (1500 mg) of the mixture therapy for the normal rat were evaluated, their blood glucose levels, glucose tolerance, body weight and insulin levels were observed and its possible mechanism were analyzed. Results Compared with the model group, the disease diabetic rats of the administered group (250mg/kg,500mg/kg,1500mg/kg) were significantly alleviated. First of all, coat color was more shiny, the behavior were more physical agility. Followed by the decrease of blood glucose levels and AUC, and body weight and insulin levels were elevated. In cell experiments, the number of islet cells was increased in the administered group by the mixture in a dose-dependent manner. Conclusion The mixture of kelp extract, wolfberry, and Chinese yam had obvious hypoglycemic effect. The hypoglycemic activity of the mixture may be attributed to increase insulin secretion through inhibit apoptosis of islet β-cells.
