摘要: 目的: 探讨催化性抗氧化剂AEOL-10150对氮芥诱导小鼠肝损伤的保护作用及其机制。方法: 实验对象为C57BL/6小鼠,采用腹腔单次注射盐酸氮芥(2 mg/kg)构建急性肝损伤模型,染毒后0.5和6 h分别给予AEOL-10150(5 mg/kg)进行治疗干预,染毒3 d后处死小鼠,收集眼球血液和肝组织,观察肝组织大体改变和HE染色后进行组织病理学检测;检测血清谷丙转氨酶(ALT)和谷草转氨酶(AST)活性,肝组织活性氧(ROS)水平、丙二醛(MDA)含量和还原型谷胱甘肽(GSH)含量,肝组织氧化还原调控分子Nrf-2的mRNA表达水平,肝组织髓过氧化物酶(MPO)活性,血清炎症因子TNF-α、IL-1β含量。结果: 2 mg/kg的氮芥单次腹腔注射3 d后可以成功诱导小鼠肝组织氧化损伤和炎症反应。与氮芥染毒组小鼠相比,AEOL-10150治疗组动物肝组织病理损伤程度减轻,血清ALT和AST活性降低,同时肝组织ROS水平和MDA含量显著减少,伴有GSH含量增加和Nrf-2的mRNA和蛋白表达水平降低(均为P<0.05)。此外,AEOL-10150治疗组小鼠的肝组织MPO活性及血清TNF-α、IL-1β浓度较氮芥染毒组显著降低(均为P<0.05)。结论: AEOL-10150能够有效减轻氮芥诱导的小鼠急性肝损伤,其机制可能与直接抗氧化作用及抗炎效应有关。

Abstract: OBJECTIVE: To investigate protective effects of a catalytic antioxidant AEOL-10150 against nitrogen mustard-induced liver injury and related mechanisms. METHODS: A single intraperitoneal injection of nitrogen mustard hydrochloride (2 mg/kg) was used to construct a nitrogen mustard-induced acute liver injury model in C57BL/6 mice. AEOL-10150 (5 mg/kg) was given 0.5 and 6 h for treatment intervention after nitrogen mustard exposure,and sacrificed after 3 days of exposure. For clarifying the AEOL-10150 has a protective effect on nitrogen mustard-induced liver injury in mice,the following indicators were evaluated:gross liver tissue changes and pathological changes by HE stain;serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities;liver tissue reactive oxygen species (ROS) level,malondialdehyde (MDA) content;reduced glutathione (GSH) content;liver tissue redox regulatory molecule Nrf-2 mRNA and protein expression level;liver tissue myeloperoxidase (MPO) activity,and serum inflammatory factors TNF-α,IL-1β content. RESULTS: A single intraperitoneal exposure of 2 mg/kg nitrogen mustard successfully induced oxidative damage and inflammatory response in livers of mice in the 3rd day. Compared with nitrogen mustard-exposed mice,the AEOL-10150 intervention reduced liver tissue pathological damage,decreased serum ALT and AST activities,and significantly reduced liver tissue ROS and MDA levels,accompanied by the increased GSH content and the decreased Nrf-2 level. In addition,the liver tissue MPO activities and serum TNF-α and IL-1β concentrations of mice in the AEOL-10150 intervention group were significantly lower than those in the nitrogen mustard-exposed group. CONCLUSION: AEOL-10150 effectively alleviated the acute liver injuries which were induced by nitrogen mustard in mice,and its mechanism might be related to direct antioxidant effect and anti-inflammatory effect.
