RESUMEN

To study the effect of dihydroartemisinin(DHA) on hepatic inflammation and lipid metabolism in weaned piglets, a liver injury model of weaned piglets was established by lipopolysaccharide(LPS)-induced method. In this study, 30 healthy weaned piglets were selected and randomly divided into control group(CON), model group(LPS) and treatment group(LD, LPS+DHA), with 10 in each group. The CON group and the LPS group were fed with a basal diet, and the LD group was fed with a basal diet+80 mg·kg~(-1) DHA. The test period was 21 days. The LPS group and the LD group were intraperitoneally injected with 100 μg·kg~(-1) LPS at 4 hours before slaughter, and the CON group was injected with the same dose of sterile physiological saline. The results showed that compared with the CON group, contents of TC, AST activity and AST/ALT ratio were significantly increased in the serum of LPS piglets(P<0.05), content of HDL-c was significantly decreased(P<0.05). In addition, in the liver, the levels of TG, NEFA, IL-1β, IL-6 and TNF-α were increased significantly(P<0.05), and activities of LPL, HL and TL were decreased significantly(P<0.05). Compared with LPS group, content of TC, activities of AST and ALT and the AST/ALT ratio were decreased significantly(P<0.05), and HDL-c content increased significantly in the serum of LD piglets(P<0.05). The contents of TG, NEFA, IL-1β, IL-6 and TNF-α and activity of FAS in the liver were decreased significantly(P<0.05), and the activities of LPL, HL and TL were increased significantly(P<0.05). Compared with the CON group, the mRNA expressions of IL-1β, IL-6, TNF-α, ACCβ and SREBP-1 c in the LPS group were significantly increased(P<0.05), the mRNA expressions of AMPKα, SIRT1, CPT-1 and SCD were decreased significantly(P<0.05). The above indicators were improved in the LD group compared with the LPS group. These results indicated that DHA had a certain effect in recovering LPS-induced liver inflammation and abnormal lipid metabolism.
