摘要:

目的:研究正膏坊龟苓膏对拘束负荷诱发小鼠应激性肝损伤的保护作用。方法:对于18h 拘束负荷诱发应激性肝损伤的小鼠,分别用赖氏法测定其血浆丙氨酸氨基转移酶(ALT)活性、硫代巴比妥酸法测定肝组织丙二醛(MDA)含量、Griess 化学法测定一氧化氮(NO)含量、荧光酶标仪测定肝组织抗氧化能力指数(ORAC)、HPLC 法测定谷胱甘肽(GSH)含量、比色法测定谷胱甘肽过氧化物酶(GPX)和谷胱甘肽硫转移酶(GST)活性。结果:与拘束应激模型组相比,正膏坊龟苓膏可以明显降低拘束负荷小鼠血浆ALT 活性、肝组织MDA 和NO 含量,有效提高肝组织的ORAC 指数、GSH 含量及GPX 和GST 活性。结论:正膏坊龟苓膏对拘束负荷诱发小鼠应激性肝损伤有一定的保护作用,其作用可能与缓解拘束负荷小鼠的氧化应激水平相关。

Abstract:

Objective:To investigate the protective effects of Zhenggaofang-Guilinggao (GLG) on liver injury of mice induced by restraint stress. Methods:The liver injury model of mice was established under restraint stress for 18 h. Hepatic function was evaluated through assaying alanine aminotransferase (ALT) activity in plasmabu by Reitman-Frankel method, malondialdehyde (MDA ) content by TBARS method. NO content by Griess chemical method, oxygen radical absorbance capacity (ORAC) using enzyme-mark instrument, glutathione (GSH) level by HPLC method, and hepatic glutathione peroxidase (GPX) and glutathione S-transferase (GST) activities by colorimetric method. Results: Compared with the control group of restraint stress, GLG can significantly decrease the ALT activity and the contents of MDA and NO, and increase the levels of ORAC and GSH, the acticities of GPX and GST in liver. Conclusion: GLG has protective effects on liver injury in mice loaded with restraint stress, and the effect may be related to its ability of releasing the level of oxidative stress in mice.

Key words: Zhenggaofang-Guilinggao (GLG), restraint stress, liver injury, oxidative stress status
