Abstract:
Objective To observe the protective effect of asiatic acid on hyperlipidemia golden hamsters induced by high fat diet and explore its mechanism.Methods Hyperlipidemic golden hamsters fed with high-fat diet were administered orally with asiatic acid (8,16,32 mg/kg)for 4 weeks.Levels of serum lipid content,liver histology,hepatic GSH-PX and SOD levels,serum ALT and AST activities were evaluated in golden hamsters,fluorescence quantitative polymerase chain reaction(RT-PCR)is using to examine the liver lecithin cholesterol fatty acyl transferase(LCAT) and class B typeⅠscavenger receptor(SR-BⅠ)mRNA expression. Results Compared with model group,the levels of TC,TG,LDL-C,TC/HDL,ALT and AST in low and mediate asiatic acid groups were all significantly decreased but the levels of SOD and GSH-PX were significantly increased(P<0.01).HE staining results showed that fat deposition in the liver were improved by administration of asiatic acid,and the expression of LCAT and SR-BⅠmRNA were increased.Conclusion Asiatic acid can effectively reduce blood lipid levels,and alleviate liver damage of the hyperlipidemia golden hamsters by lipid regulation and antioxidative ability augmentation.The increased levels of LCAT and SR-BⅠmRNA expression maybe involved in the mechanism of hypolipidaemic effect of asiatic acid.
