摘要: 目的 研究甘草酸二铵脂质复合物(α-diammonium glycyrrhizinate phosphatidylcholine complex, DGLL)对D-氨基半乳糖(D-GalN) 以及CCl4 所致小鼠化学性肝损伤的保护作用及其机制。方法 采用在体和离体两种方法观察:在体以D-GalN 诱导小鼠急性肝损伤模型, 测定各组肝损伤小鼠血清谷丙转氨酶(ALT) 、谷草转氨酶(AST) 活性, 及肝组织丙二醛(MDA)、黄嘌呤氧化酶(XOD) 、谷胱甘肽过氧化物酶(glutathione peroxidase, GSH-PX)、一氧化氮(NO) 、一氧化氮合成酶(NOS) 、诱生型一氧化氮合酶(iNOS) 含量。体外实验采用小鼠离体肝细胞原代培养, 并建立CCl4 诱导肝细胞坏死性损伤模型, 检测DGLL 对其的影响。结果 DGLL 能显著降低小鼠血清中升高的ALT 、AST, 降低XOD 活力和过氧化物终产物MDA 的含量。对氧化应激引起的肝脏GSH 含量下降具有升高作用。DGLL 可以显著降低离体培养中染毒肝细胞中的ALT 水平。结论 提示DGLL对小鼠化学性肝损伤具有显著的保护作用。

Abstract: AIM: To investigate the protective effect of α-diammonium glycyrrhizinate phosphatidylcholine complex(DGLL) on chemical liver injury and its possible mechanisms.METHODS: The acute hepatic injury model inmice was induced by D-GalN.We measured the changes of activity of ALT and AST in serum and MDA,XOD, GSH-PX, NO, NOS and iNOS content of liver tissue.The model of chemical liver injury in mice was prepared.In vitro, primary cultured mice hepatocyte was injured by CCl4 , and the level of ALT in medium was measured to study protective effect of DGLL.RESULTS: DGLL could decrease the activities of ALT and AST in serum and the MDA, XOD, NOS and iNOS content of liver tissue, and was able to increase the activities of GSH-PX content of liver tissue.In vitro, it is indicated that GPLL had a notable protective effects on the hepatocyte injured by CCl4 and could suppress the level of ALT.CONCLUSION: DGLL had notable protective effect against acute liver injury in mice.

Key words: α-diammonium glycyrrhizinate phosphatidylcholine complex , chemical liver injury, primary hepatocyte
