AIM: To explore the therapeutic effects of recombinant human augmenter of liver regeneration (ALR) on CCl4 liver damage of mice.
METHODS: The recombinant human ALR was prepared by standard procedure of fermentation and chromatography techniques. Chemical liver damage model of mice was established by CCl4. The mice were divided into two groups: group one was treated by recombinant ALR, 2 mg/kg or 20 g, 1/12 h, 4 times, and group two was treated by normal saline as control. After treatment, the mice were sacrificed for collecting the blood sample. For evaluation of chemical liver damage, the serum ALT and AST levels were determined by an autobiochemical processor.
RESULTS: The CCl4 liver damage model was established. After the treatment with recombinant human ALR, the ALT and AST levels in treated groups were significantly decreased as compared with the group treated with normal saline (ALT: 991 U/L vs 2134 U/L, P < 0.01; AST: 938 U/L vs 1873 U/L, P < 0.01), indicating the potent therapeutic effects of recombinant human ALR on mice model of chemical damage caused by CCl4.
CONCLUSION: Recombinant human ALR is successfully prepared and effective in the treatment of murine CCl4 liver damage.
