| 摘 要： | 观察江蓠藻膳食纤维对糖尿病小鼠的血糖,以及血清中某些抗氧化指标的效应,探讨其降血糖的可能作用机理.结果表明,江蓠藻膳食纤维能显著降低四氧嘧啶糖尿病小鼠的血糖值,且以中剂量(0.4 g.kg-1)江蓠藻膳食纤维的降血糖作用最佳.此外,江蓠藻膳食纤维可降低四氧嘧啶糖尿病小鼠血清中的丙二醛(MDA)浓度,提高超氧化物歧化酶(SOD)活性,改善糖尿病小鼠的氧化应激水平.

| Abstract: | The effects of dietary fiber from Gracilaria (GDF) on blood glucose in diabetic mice and some anti-oxidative indexes in the serum were observed,and the mechanism of GDF lowering blood glucose was also discussd.The results indicated that GDF could obviously decrease the blood glucose levels of alloxan-induced diabetic mice,and the hypoglycemic effect of GDF at the middle dose of 0.4 g·kg~(-1) was the best Moreover,GDF could significantly decrease the content of malondialdehyde (MDA) in the serum of alloxan-induced diabetic mice,increase the activity of superoxide dismutase (SOD) and improve the oxidative stress levels of diabetic mice. |
