The aim is to investigate the hypoglycemic effect of Laminaria japonica polysaccharides (LJPS) on type 2 diabetes mellitus (T2DM) mice model. 60 healthy male mice have been used in the experiment. T2DM animal mode was prepared by high fatty forage feeding and intraperitoneal injection with alloxan. Diabetic mice were orally supplied with LJPS. Then their blood was collected for various biomedical measurements of fasting blood glucose (FBG), serum insulin, and amylin. Treatment with LJPS significantly reduced fasting blood glucose ( ) and increased the levels of insulin and amylin in serum ( ). Overall, the study presented that LJPS can reverse several components of T2DM. Therefore, LJPS may become a new oral candidate medicine for the treatment of diabetes.
