Résumé
Objective To investigate the protective effects of polysaccharide from Radix Codonopsis Lanceolatae on acute alcoholic hepatic injury in mice.Methods The model of CCl4-induced acute hepatic injury was set up in mice, and then treated with polysaccharide from Radix Codonopsis Lanceolatae to observe the activities of ALT, AST and TG in serum and the levels of SOD, GSH and MDA in hepatic tissue and Observed the pathological changes in the liver of mice.Results Compared with model control group, the lance asiabell root polysaccharide liver injury in mice all dose groups in the activity of serum ALT(97.5 ± 22.12 U/L, 108.8 ± 22.15 U/L, 125.2 ± 19.68 U/Lvs. 152.3 ± 17.32 U/L), AST (72.5 ± 21.3 U/L, 89.2 ± 17.47 U/L, 104.3 ± 19.34 U/Lvs.1215 ± 22.31 U/L) and TG(0.75 ± 0.32 mmol/L, 0.80 ± 0.22 mmol/L, 0.96 ± 0.21 mmol/L vs.1.44 ± 0.23 mmol/L) reduce, can increase the liver damage the activity of SOD(215.6 ± 22.68 U/mg, 203.2 ± 22.18 U/mg, 186.2 ± 18.34 U/mgvs.164.3 ± 17.54 U/mg), GSH(17.74 ± 2.12μmol/g, 14.84 ± 1.12μmol/g, 13.93 ± 2.15μmol/gvs.12.23 ± 2.09μmol/g) in liver tissue of mice, decrease the activity of MDA(6.22 ± 2.12 nmol/mg, 6.22 ± 2.12 nmol/mg, 8.36 ± 1.84 nmol/mgvs.9.35 ± 1.68 nmol/mg) in liver tissue, showing significant differences (P<0.05), and there was certain dose dependent, and can improve the pathological injury of liver tissue.Conclusion Polysaccharide from Radix Codonopsis Lanceolatae had protective effects on acute liver induced by acute alcoholic hepatic injury in mice.
