摘要: 为研究猕猴桃对糖尿病小鼠的糖、脂质代谢及氧化应激的影响,采用尾静脉注射四氧嘧啶诱导糖尿病小鼠模型,糖尿病小鼠随机分为11组:猕猴桃石油醚部位高中低剂量组、乙酸乙酯部位高中低剂量组、正丁醇部位高中低剂量组、阳性对照组和模型组,并设置空白组。结果表明石油醚部位低剂量组(P<0.01, P<0.01)和乙酸乙酯部位高剂量组(P<0.05,P<0.001)均能显著性的降低餐后血糖和空腹血糖,乙酸乙酯部位中剂量组(P<0.001)和正丁醇部位低剂量组(P<0.001)降低餐后血糖效果较好,正丁醇部位中剂量组(P<0.05)降低空腹血糖效果较好;石油醚部位高剂量(P<0.01)、乙酸乙酯部位3个剂量组(P<0.05,P<0.01,P<0.05)和正丁醇部位低剂量组(P<0.01)均能显著性升高肝糖元含量;3个部位的3个剂量组均能显著性降低TCH的含量(P<0.01),石油醚高低剂量(P<0.05, P<0.001)、正丁醇部位高低剂量组(P<0.05,P<0.05)以及乙酸乙酯部位高剂量(P<0.05)组均能够显著性降低TG含量;3个部位的3个剂量组均能显著升高SOD水平(P<0.05),石油醚部位3个剂量组(P<0.001,P<0.001,P<0.001)、正丁醇部位3个剂量组(P<0.001,P<0.01,P<0.001)以及乙酸乙酯部位高剂量组(P<0.001)均能显著性降低MDA含量。由此可见猕猴桃能改善糖尿病小鼠的糖-脂代谢,其作用机制可能与其促进肝糖元合成,抑制肝糖元分解,增强机体抗氧化防御体系有关。

Abstract: The effect of Actinidia chinensis on glycolipid metabolism and oxidative stress of diabetic mice was evaluated with diabetic mice model induced by intravenous injection of alloxan.The diabetic mice were randomly divided into 11 groups:petroleum ether extract group(high,medium and low dose,respectively),EtOAC extract group (high,medium and low dose,respectively),n-BuOH extract group (high,medium and low dose,respectively),positive control group,model group,and set the blank group.Results showed that low dose group of petroleum ether extract (P<0.01 and P<0.01,respectively) and (P<0.01) and high dose group of EtOAC extract (P<0.05 and P<0.001,respectively) could significantly decrease postprandial blood glucose and fasting blood glucose,medium dose group of EtOAC extract(P<0.001) and low dose group of n-BuOH extract(P<0.001) had better effects on decreasing postprandial blood glucose,medium dose group of n-BuOH extract(P<0.05) had better effects on decreasing petroleum ether extract.High dose group of petroleum ether extract (P<0.01),three dose groups of EtOAC extract (P<0.05,P<0.01 and P<0.05,respectively) and low dose group of n-BuOH extract (P<0.01) could significantly increase the content of liver glycogen.Three dose groups of the three extracts all could significantly increase the content of TCH (P<0.05),high and low dose goups of petroleum ether extract (P<0.05 and P<0.001,respectively) and n-BuOH extract (P<0.05 and P<0.05,respectively),high dose group of EtOAC extract (P<0.01) could significantly increase the content of TG.Three dose groups of the three extracts could significantly increase the level of SOD (P<0.05),three dose groups of petroleum ether extract (P<0.001, P<0.001 and P<0.001,respectively) and n-BuOH extract (P<0.001, P<0.01 and P<0.001,respectively) and high dose group of EtOAC extract (P<0.001) could significantly decrease the content of MDA.Thusit canbe seen that A.chinensis extracts could improve glycolipid metabolism of diabetic mice including hepatic glycogen synthesis promoting,excessive degradation inhibited,and antioxidant defense system strengthened as the mechanism of A.chinensis.
