ABSTRACT
BACKGROUND: Great concerns haven been given increasingly on inhibition of nutrient with antioxidation efficacy on lipid peroxidation and its effect on prevention of cardiac vascular disease.OBJECTIVE: To probe into the effects of plantain seed that acts on eliminating oxygenic free radical and antioxidation on lipid metabolism and antioxidation in rats.DESIGN: Randomized control experiment was designed.SETTING: Experimental Room of Pharmacology and Toxicology of New Drug in Hebei Province.PARTICIPANTS: The experiment was performed in Experimental Room of Pharmacology and Toxicology of New Drug in Hebe Province from January to December 2004, in which, 40 SD rats were employed, provided from Hebei Experimental Animal Center, of healthy grade I, mass weighted (210±22) g and of either sex. They were randomized into 5groups, named, blank control, positive control, low dosage experiment group, moderate dosage experiment group and high dosage experiment group, 8 rats in each one.METHODS: In blank control, the rats were bred everyday with basic forage that was tallied with AoAc animal nutrient criteria and they were free of drinking. In positive control, the rats were bred with high-lipid forage and free of drinking. In the groups of low, moderate and high dosages of plantain seed, the rats were bred with 2.5 g/kg, 5 g/kg and 15 g/kg plantain seed successively besides high-lipid forage and they were free of drinking. The weight was measured and the food intake was recorded every week. Fasting blood was collected to check total cholesterol in serum once every two weeks. The experiment was end in 12 weeks. Under anesthesia,the blood was collected from hypogastric aorta to check the level of serum blood lipid and the activities of superoxide dismutase (SOD) and catalase.After blood collection, the heart and liver were extracted immediately for management to measure SOD activity and content of lipid peroxide (LPO)in myocardial tissue and the activities of catalase and glutathione peroxidase in liver tissue.MAIN OUTCOME MEASURES: Level of blood lipid and activities of SOD and catalase in rats.RESULTS: Forty rats were employed and all entered result analysis. [1]Serum total cholesterol: It was lower significantly in high dosage group compared with positive control [(1.40±0.13, 1.83±0.13) mmol/L, P ＜ 0.05].[2] Serum SOD activity: It was lower remarkably in positive control compared with blank control [(174.29±10.33, 193.19±.7813) NU/mg, P ＜ 0.05].[3] LPO content in serum: It was higher significantly in positive control compared with blank control [(3.64±0.26, 2.91±0.50) mmol/mg, P ＜ 0.05]and it was lower significantly in moderate dosage group compared with positive control (3.13±0.26, 3.64±0.26, P ＜ 0.05). [4] Activity of catalase in liver tissue: It was lower remarkably in positive control compared with normal control (34.64±3.26, 44.72±2.67, P ＜ 0.05) and it was higher remarkably in moderate dosage group compared with positive control (44.84±3.79,34.96±3.64, P ＜ 0.05).CONCLUSION: Plantain seed reduces the levels of total cholesterol,triglycerin (TG) and LPO in serum and increases SOD activity. At the concentration of 15 g/kg, plantain seed acts most remarkably on eliminating oxygenic free radical and antioxidation and alleviates lipid metabolic disturbance.

ABSTRACT
Objective: To investigate the effect of Plantago asiatica L. on antioxidation in rats. Methods: The antioxidative enzymes and LPO of serum, heart, and liver tissues were determined. Results: The activities of superoxide (SOD) in serum and heart were significantly lower than that of the control. The lipid peroxide (LPO) level in serum and heart was markedly higher than that of the control. Serum and liver catalase (CAT) activities in rats fed with high fat were decreased. Activities of liver glutathione peroxidase (GSH Px) in high fat rats were decreased significantly. The production of SOD activities in serum and liver and GSH Px in liver were increased significantly in rats maintained on Plantago asiatica L. supplemented diets, meanwhile serum and heart LPO were reduced. Conclusion: 15g/kg Plantago asiatica L. can increase the antioxidation against lipid peroxide in hyperlipidemic rats.
