BACKGROUND: Emblic leafflower fruit contains rich vitamin C, organic acid and mineral substance. It is indicated in modern research that emblic leaafflower fruit acts on preventing from cancer and anti-aging too. In recent years, more and more concerns have been paid to the researches on functional factor of emblic leafflower fruit and the development of the relevant functional food. It has been verified that emblic leafflower fruit acts on reducing lipid and anti-oxidation in vitro, but there are still lacks of enough basic researches to support it.OBJECTIVE: To probe into mechanism of emblid leafflower fruit on anti-oxidation and protection of vascular endothelial function in rabbits with hyperlipemia.DESIGN: Randomized controlled experimental study based on the experimental animals.SETTING: Atherosclerosis(As) experimental room in a university hospital.MATERIALS: Totally 24 normal NewZealand male rabbits, mass weighted (2.2±0.5) kg.METHODS: The experiment was performed in As Experimental Room of Beijing Anzhen Hospital from September 2001 to May 2002. Totally 24 New Zealand male rabbits were randomized into the control, the power of emblid leafflower fruit group(powder group)(4 g/kg day) and hypercholesterolemia model group (model group), 8 rabbits in each group. In both power and model groups, the rabbits were fed with hypercholesterol food. Oxidase method was applied to assay the content of serum lipid, chemical method to assay the plasma total anti-oxidation and the content of malondialdehyde (MDA), radio-immune method to assay the content of plasma endothelin-1 (ET-1), digoxin labeled probe and tissue hybridism in situ to assay the expression of endothelin mRNA of aortic tunica intima, and image analyzer to assay the area of aortic intimal atherosclerosis plaque and the ratio between the area of tunica intima and the area of tunica media.MAIN OUTCOME MEASURES: The primary outcomes included blood lipid level, serum MDA concentration and the comparison of artery plaque areas. The secondary outcomes included the changes in plasma ET-1.RESULTS: By the comparison between the powder group and model group in triglyceride(TG) and low density lipoprotein cholesterol(LDL-C) were significantly reduced [(11.70 ± 1.73), (14.32 ±2.22) mmol/L, P<0.05; (0.740 ± 0.107), (1.450 ± 0.220) mmol/L, P <0.01 successively]and thehigh density lipoprotein cholesterol(HDL-C) was increased MDA was significantly decreased [ (3.88 ± 0.51 ), (6. 29 ± 1.43 ) mmol / L,P < 0.01 ] and the total anti-oxidation significantly increased [ (10. 771der photo-microscope that the plaque area and the ratio between intima area and media area were remarkably decreased [(39.46±6.53), (50.69± 12.36)mmol/L, P < 0.05; (0. 62 ±0. 32), (1.38 ±0.38) mmol/L, Pgranules of aortic intima ET-1 gene were rem~kably decreased compared with the model group.CONCLUSION: Emblic leafflower fruit prevents from the formation of experimental atheromatous plaque in rabbits probably by regulating rabbit lipid metabolism, improving anti-oxidation to reduce lipid peroxidation and protecting endothelial function to inhibit the expression of artery intima ET-1 gene.
