摘要/Abstract

摘要： 探讨灯盏细辛提取物的体内抗氧化活性以及对2型糖尿病小鼠肝脏、胰腺损伤的保护作用。采用高脂高热量饲料喂养加小剂量四氧嘧啶诱导的方法建立2型糖尿病模型，用试剂盒测定并比较了试验组与模型组及正常组的血清总超氧化物歧化酶（T-SOD）活性及丙二醛（MDA）的含量，并在光镜下观察小鼠胰腺和肝脏组织的形态学改变。实验结果表明，灯盏细辛提取物能够显著提高2型糖尿病小鼠的血清T-SOD的活性（P<0.05），明显降低其血清MDA的含量（P<0.05），各组病理损伤有较显著差异，其中模型组的损伤明显高于其余各组。可见灯盏细辛提取物具有较强的体内抗氧化作用，对2型糖尿病小鼠肝脏、胰腺损伤具有一定保护作用。

Abstract: The objective of this study was to evaluate the antioxidant activity of Erigeron breviscapus extract and the protective effect of E.breviscapus extract on pancrea and liver injuries of type 2 diabetes mice.Type 2 diabetes mice model was induced by high-glucose-high-fat diet and small dose of alloxan.The T-SOD activity and MDA concentration of all mice serum were determined by Kit.The morphological changes of pancrea and liver tissues in mice were observed under light microscope.The results showed that the extracts of E.breviscapus can significantly increase the T-SOD activities of type 2 diabetes mellitus serum (P<0.05),and obviously decrease the concentration of MDA (P<0.05).The difference between their pathological injuries was significant(P<0.05),the model group was obviously higher than those of the other groups.It indicated that the extracts of E.breviscapus had significant antioxidant effect and had some protective effects on pancrea and liver injuries of type 2 diabetes mice.

Key words: Erigeron breviscapus extract, T-SOD, MDA, type 2 diabetes mice
