摘要: 目的:观察诺丽果汁和纳豆两种发酵食品对实验性糖尿病小鼠血糖及血脂的影响。方法:ICR雌性小鼠一次性尾静脉注射四氧嘧啶(55 mg/kg),72 h后将空腹血糖值≥ 12.00 mmol/L、尿糖呈强阳性(+++)者视为糖尿病小鼠模型。将糖尿病模型小鼠随机分为3组(n=10):模型(DM)组、诺丽果汁(NJ)组和纳豆(NT)组,另取10只正常ICR雌性小鼠作为正常对照(NC)组。NJ组、NT组分别给予诺丽果汁(25.0 ml/kg)、纳豆(0.6 g/kg)灌胃,其他两组小鼠分别给予生理盐水(25.0 ml/kg)灌胃,连续给药30 d,小鼠自由进食、饮水,记录小鼠饮水量及进食量。末次给药后1.5 h,测定小鼠葡萄糖耐量,经股动脉采血测定小鼠糖化血清蛋白(GSP)、血清胰岛素(Ins)和血脂等指标的变化情况。结果:与NC组比较,DM组小鼠饮水量、进食量、GSP及血清总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白(LDL)等均显著升高(P<0.01),葡萄糖耐量、Ins及高密度脂蛋白(HDL)均显著降低(P<0.01);与DM组比较,NJ组与NT组小鼠GSP、TG及LDL均明显降低(P<0.01,P<0.05),葡萄糖耐量、Ins和HDL明显升高(P<0.05)。结论:诺丽果汁与纳豆具有降低糖尿病模型小鼠血糖、增加糖耐量及改善血脂的作用,提示二者对糖尿病防治可能具有一定的应用价值。

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.
