Protective Effects of Galactoside-modified Oleanolic Acid Solid Lipid Nanoparticles on CCl_4-induced Acute Hepatic Injury in Rats / 中国药房

OBJECTIVE:To explore the protective effect of galactoside-modified oleanolic acid solid lipid nanoparticles(OA-G10SLN)on CCl4-induced acute hepatic injury of rats.METHODS:A total of 60 mice were assigned to normal control group,model group,OA regular solution group or OA-G10SLN group(25.0,12.5,and 2.5 mg?kg-1).Each group was injected from venal caudalis with corresponding drug q.d.for 7d.Acute hepatic injury model was induced by CCl4 on day 6 after medication except for the normal control group.The mice were sacrificed at d7 with serum levels of AST and ALT determined and histopathologic test of liver tissues performed.RESULTS:In OA-G10SLN group compared with model group,the serum levels of AST and ALT decreased markedly(P
