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
