Effect of Cholecalciterol Cholesterol Emulsion on Liver of Zymosan-induced Multiple Organ Failure in Mice / 中国医科大学学报

ABSTRACT

Objective To study the effect of cholecalciterol cholesterol emulsion(CCE)in the zymosan(Z)-induced acute hepatic injury. Meth-ods A total of 36 C57 BL/6 mice were randomly divided into 4 groups,namely negative control(CON)group,CCE group,Z group and CCE+Z group,respectively. There were 9 mice in each group. Mice from CON group and Z group were fed with pure water. Mice from CCE group and CCE+Z group were fed with cholecalciterol cholesterol emulsion 20μL dissolved in 200 mL pure water which was kept in darkness. After 14 days, Z group and CCE+Z group were injected with zymosan at a dose of 500 mg/kg. After 18 hours,all the mice in each group were sacrificed. The liver tissues were harvested for histopathological examination. The serum ALT levels were determined. The molecular expression of IL-6 and IL-18 in liv-er tissue of mice were evaluated by Western blotting and real-time quantitative PCR method. Results The results of histopathological examination showed that liver tissue damage in CCE+Z group was lighter than that of Z group ,and heavier than that of the CON group. Compared to the CON group,Z group had the highest serum ALT level,followed by CCE+Z group,while in Z group was significantly lower than that in CON group(all P<0.05). The expression of IL-6 and IL-18 protein and mRNA showed level of Z group was apparently higher than those of CON group and CCE+Z group(all P<0.05). Conclusion Cholecalciterol cholesterol emulsion can play certain protective effect on zymosan-induced liver injury in mice.
