摘要: 目的: 利用内皮细胞氧化损伤模型和鹌鹑饵食性高脂血症模型,研究β-榄香烯的抗氧化损伤作用。 方法: 采用过氧化氢(H2O2)建立体外培养的人脐静脉内皮细胞(HUVEC)氧化损伤模型,观察不同浓度(0.1、1、10 mg/L)β-榄香烯对细胞内活性氧水平、丙二醛(MDA)含量和超氧化物岐化酶(SOD)活性的影响;采用高脂饲料喂养法建立鹌鹑高脂血症模型,观察β-榄香烯对鹌鹑血清SOD活性、MDA和一氧化氮(NO)含量的影响。 结果: β-榄香烯可降低内皮细胞内活性氧水平,升高SOD活力,降低MDA含量;β-榄香烯升高鹌鹑血清中SOD活性和NO含量,降低MDA水平。 结论: β-榄香烯具有较强的抗氧化、清除氧自由基及保护血管内皮细胞作用。

Abstract: AIM: To investigate the role of β-elemene as an antioxidant in the damage of HUVEC and hyperlipemia quail. METHODS: Human umbilical vein endothelial cell (HUVEC) was treated either with 0.5 mmol/L of H2O2 alone or with β-elemene for 24 h followed by 0.5 mmol/L of H2O2 for 2 h. The contents of superoxide dismutase (SOD), malondialdehyde (MDA) and reactive oxygen species (ROS) were measured; Hyperlipemia model of quail were established by feeding high fat diet. The levels of SOD, MDA and nitric oxide(NO) in the serum were measured. RESULTS: The levels of ROS and MDA decreased while the level of SOD increased in HUVEC after treated with β-elemene. Compared with the model group, β-elemene decreased serum MDA level, increased serum SOD activity and NO level of quail significantly. CONCLUSION: β-elemene mediates antioxidant effects on the oxidative stress induced by H2O2 in vitro; β-elemene has preventive effect on hyperlipemia quail.
