To investigate the effect of N. nucifera hydroalcoholic seed extract on fasting blood glucose (FBG) levels, glucose transporter (GLUT)-4 mRNA, and GLUT-4 protein in the adipose tissue of streptozotocin (STZ)-induced diabetic rats.
Male Sprague Dawley (SD) rats were first fed with a high-fat diet (HFD) for three weeks, and then, diabetes was induced by intraperitoneal injection of STZ at a dose of 35 mg/kg bw. Rats were divided into four groups: group 1: normal rats (NC), group 2: STZ-induced diabetic rats (DC), group 3: diabetic rats with N. nucifera hydroalcoholic seed extract at a dose of 400 mg/kg bw (NN), and group 4: diabetic rats with metformin at a dose of 100 mg/kg bw (MET) for 28 days.
FBG level was significantly lower in the NN group than in the DC group ( < 0.05). Also, the NN group increased GLUT-4 mRNA expression and GLUT-4 protein in the adipose tissue when compared to the diabetic group.
We conclude that the observed hypoglycemic effect of N. nucifera seed extraction in STZ-induced diabetic rats could be due to insulinomimetic activity.
研究莲种子水醇提取物对链脲佐菌素(STZ)诱导的糖尿病大鼠空腹血糖(FBG)水平、脂肪组织中葡萄糖转运蛋白(GLUT)-4 mRNA和GLUT-4蛋白的影响。
雄性Sprague Dawley(SD)大鼠先喂高脂饮食(HFD)3周,然后腹腔注射35 mg/kg体重的STZ诱导糖尿病。大鼠分为四组:第1组:正常大鼠(NC);第2组:STZ诱导的糖尿病大鼠(DC);第3组:给予400 mg/kg体重莲种子水醇提取物的糖尿病大鼠(NN);第4组:给予100 mg/kg体重二甲双胍的糖尿病大鼠(MET),持续28天。
NN组的FBG水平显著低于DC组(<0.05)。此外,与糖尿病组相比,NN组脂肪组织中GLUT-4 mRNA表达和GLUT-4蛋白增加。
我们得出结论,莲种子提取物在STZ诱导的糖尿病大鼠中观察到的降血糖作用可能归因于胰岛素样活性。
