Abstract: Objective:To investigate the effect of two kinds of fermented food, noni juice and natto, on blood glucose and lipids in induced diabetic mice. Methods:Female (ICR) mice were induced into diabetes by an injection of alloxan (55 mg/kg, i. v.). After 72 hours, those mice whose fasting blood glucose levels were over 12.00 mmol/L and urine sugar was strongly positive (+ + +) were regarded as diabetical model and were randomly divided into three groups (n=10):diabetical model (DM) group, noni juice (NJ) group and natto (NT) group. Another ten normal female ICR mice were taken as normal control (NC) group. The mice in NJ and NT groups were gavaged with noni juice (25.0 ml/kg) and natto (0.6 g/kg) respectively. The other two groups were given normal saline (25.0 ml/kg). Continuous gavage administration was given for 30 days, the water-drinking volume and food-intake were recorded. After 1.5 h of the last administration, the glucose tolerance of mice was measured. Finally, the changes in glycated serum protein(GSP), insulin(Ins) and blood lipids of blood samples of mice, taken from the femoral artery, were determined. Results:Compared to the NC group, the water-drinking amount and food-intake, GSP and total cholesterol (TC), triglyceride(TG) and low density lipoprotein (LDL) in DM group were increased significantly (P<0.01), while glucose tolerance, Ins and high density lipoprotein (HDL) were decreased significantly (P<0.01). However, when it came to DM group, NJ and NT could significantly (P<0.01 or P<0.05) reduce, GSP, TG and LDL, meanwhile improve glucose tolerance, Ins and HDL (P<0. 01). Conclusion:Both noni juice and natto could reduce the blood glucose levels in induced diabetical mice and improve blood lipids, which suggested that they may have certain application value in prevention and treatment of diabetic mellitus.
