摘 要 目的:研究紫铆花素对PC12细胞氧化应激损伤的保护作用及对线粒体功能的影响。方法:将大鼠PC12细胞分为正常对
照组、模型组、溶剂对照组(1‰二甲基亚砜)和紫铆花素高、中、低浓度组(2、1、0.5 μmol/L)。后4组给予相应试剂/药物干预24 h
后,除正常对照组外的其余组均以100 mU/mL葡萄糖氧化酶诱导氧化应激模型。培养4 h后,检测细胞存活率、凋亡率和细胞内

ABSTRACT OBJECTIVE:To study the protective effects of butein on oxidative stress injury of PC12 cell and its effects on
mitochondrial function. METHODS:Rats PC12 cells were divided into normal control group,model group,solvent control group
(1 ‰ dimethyl sulfoxide),butein high,medium and low concentration groups(2,1,0.5 μmol/L). The latter 4 groups were given
relevant reagent/medicine for intervention;24 h later,other groups were given 100 mU/mL glucose oxidase to induce oxidant
stress model except for normal control group. After 4 h culture,cell survival rate,apoptosis rate,the levels or activities of ROS,
MDA,SOD,CAT,GSH-Px,ATP,IL-1β and TNF-α as well as the change of MMP were detected. RESULTS:Compared with
normal control group,cell survival rate,the levels or activities of SOD,CAT,GSH-Px and ATP were all decreased significantly,
and apoptotic rate,the content of ROS,the levels of MDA,IL-1β and TNF-α were all increased significantly(P<0.05 or P<
0.01),while the MMP was decreased significantly. Compared with model group,above indexes of solvent control group had no
significant change (P>0.05),cell survival rates,the levels or activities of SOD (except for medium and low concentration
groups),CAT,GSH-Px (except for medium and low concentration groups),ATP(except for low concentration group)were
increased significantly in butein high,medium and low concentration groups,while apoptotic rates,the content of ROS,the levels
of MDA,IL-1 β and TNF-α were decreased significantly (P<0.05 or P<0.01),while the MMP were increased significantly.
CONCLUSIONS:Butein can increase the antioxidant enzyme
