The study was aimed to investigate the potential therapeutic effect of Mori folium aqueous extracts (MFAE) on type 2 diabetes mellitus (T2DM) in vivo.
A rat model of T2DM was established with the combination of high sugar and high-fat diet (HSFD) and streptozotocin (STZ). The T2DM rats were administrated with low (2 g.kg-1) and high (5 g.kg-1) doses of MFAE for 60 consecutive days. The biochemical indices of glucose metabolism disorders, insulin resistance and oxidative stress were observed. The results indicated that MFAE significantly promoted the synthesis of hepatic glycogen, reduced the levels of fasting blood glucose and fasting blood insulin, and improved the insulin sensitivity index (ISI). MFAE administration also remarkably increased the levels of superoxide dismutase (SOD) and reduced the levels of malondialdehyde (MDA).
MFAE showed a therapeutic effect on T2DM with the bioative effect of improve glucose metabolism disorders, decrease insulin resistance, and ameliorate the antioxidative ability.
本研究旨在探讨桑树叶水提物(MFAE)对 2 型糖尿病(T2DM)的潜在治疗作用。
采用高糖高脂饮食(HSFD)联合链脲佐菌素(STZ)建立 T2DM 大鼠模型。T2DM 大鼠给予低(2 g.kg-1)和高(5 g.kg-1)剂量的 MFAE 连续 60 天。观察葡萄糖代谢紊乱、胰岛素抵抗和氧化应激的生化指标。结果表明,MFAE 能显著促进肝糖原的合成,降低空腹血糖和空腹胰岛素水平,改善胰岛素敏感指数(ISI)。MFAE 给药还显著提高超氧化物歧化酶(SOD)的水平,降低丙二醛(MDA)的水平。
MFAE 对 T2DM 具有治疗作用,其作用机制可能是改善葡萄糖代谢紊乱、降低胰岛素抵抗和改善抗氧化能力。
