Effects of Three Health Foods on Lipid Peroxidation and Anti-oxidation Enzyme in the Serum of Rats

目的 研究 3种保健食品对大鼠血清脂质过氧化和抗氧化酶的影响。方法 将SD(sprague dawley)老年大鼠随机分为 4组 (一个对照组 ,3个试验组 ) ,试验组喂饲受试物 30d ,采尾血测脂质过氧化产物丙二醛 (malon adehyde,MDA)和超氧化物岐化酶 (superoxidedismutse,SOD)。 结果 美因子羊胎素与宁夏枸杞王胶囊的中浓度组和高浓度组、保龄西洋参的低浓度组和中浓度组大鼠血清中MDA含量低于对照组 (P <0 .0 5 ,P <0 .0 1) ;美因子羊胎素的 3个试验组、宁夏枸杞王胶囊中浓度组和高浓度组、保龄西洋参的低浓度组大鼠血清中SOD活性高于对照组 (P <0 .0 5 )。结论

Objective To study the effects of three health foods on lipid peroxidation and anti oxidation enzyme in the serum of rats. Methods Sprague Dawley (SD) old aged rats were divided randomly into 4 groups including one control group and three experimental groups. The experimental groups were given the health foods for 30 days, and the content of malonaldehyde (MDA) and the activity of superoxide dismutase (SOD) were detected. Results MDA contents of the middle and high concentration groups in Yang Taisu and Lycium Barbbarum L capsule, and low and middle concentration groups in Bao Ling American ginseng were lower than that in control group ( P <0.05, P <0.01). The SOD activity of three concentration groups in Yang Taisu, middle and high concentration groups in Lycium Barbarum L capsule, low concentration group in Bao Ling American ginseng were higher than that in control group ( P <0.05). Conclusion Three health foods all have an effect on anti lipid peroxidation.
