In currence, se- GSH- PX activity have been been used as a standard of Selenium nourishment, GSH- PX is an extremely important protection enzyme in anti oxida- tive defend system of organize and cell of animal.It clear hydroxy radical and hyperoxide in cell respir- ation metabolism reaction ,thereby, mai- ntain cell's normal physiological function, prote- ct biomembrane and biomacromolecule from oxidative damage.If the activity is high or not, effect the ab- ility that the organize clears hyperoxize lipi- d ,directly.

目前，含se-GSH-PX活性已被作为se营养状况可一个指标，该酶是动物组织细胞抗氧化防御系统中一个极为重要的保护性酶，它是以还原型GSH为底物的谷胱甘肽参与的过氧化反应，清除细胞呼吸代谢反应过程产生的羟自由基和过氧化物，从而使细胞能维持正常的生理功能，保护生物膜和生物大分子结构免受氧化损伤。

And velvet in hypoxanthine, urine Caledonia acridine and substances such as phospholipids can inhibit the function of MAO activity; at the same time, deer horn and through the enhancement of superoxide dismutase activity and inhibited lipid peroxidation in the role, you can improve body's antioxidant capacity.

而鹿茸中的次黄嘌呤、尿喀啶和磷脂类等物质具有抑制MAO活性的功能；同时，鹿茸通过增强超氧化物歧化酶的活性和抑制脂质过氧化反应的作用，可以提高机体的抗氧化能力。

Our work reveals that GSH-Px can be damaged by peroxidation and α-tocopherol is one of the powerful antioxidants.

说明：GS H-Px较易受到过氧化反应损伤；维生素E是更为有效的抗氧化性保护物质。

ConclusionTo inhibit lipid peroxidation,increase activity of antioxidase and improve immune function might be one of the mechanisms of invigorating kidney-YIN recipe against aging.

结论抑制脂质过氧化反应，提高抗氧化酶活性，改善免疫功能可能是滋补肾阴方药延缓衰老的作用机制之一。

LDL of serum in healthy person was separated by improve precipitate method.Results:Pae(300,150 mg.kg-1)could reduce significantly the levels of MDA of serum,aorta and liver;Pae(300 mg.kg-1)decreased obviously the content of OX-LDL of plasma;Pae1 000,200,40 μg.ml-1refrained markadly the course of oxidational decorate of LDL of serum in healthy person.

结果：Pae(300，150 mg.kg-1)可明显抑制高脂大鼠血清、主动脉及肝脏脂质过氧化反应；Pae(300 mg.kg-1)显著减少高脂大鼠血浆LDL的氧化修饰；Pae(1 000，200，40 μg.ml-1)对健康人血清LDL的体外氧化反应有极显著抑制效应。

On the other hand, increased Aβ concentration from 10 to 100 μM failed to show any effect on lipid peroxidation of lysosomes, and Cu2+ at 50 μM caused a significant increase in lipid peroxidation as compared to the control or Aβ treatment.

另一方面，在相同浓度下，50 μM的铜离子所产生的脂质过氧化反应比贝他类淀粉蛋白造成的脂质过氧化有显著的增加。

This flow leads to the oxidation of a target molecule, whose decay is a measure of the lipid peroxidation reaction and, indirectly, of the ability of plasma, body fluids or simple chemical solutions to break the reaction.

这流程，间接地，导致目标分子的氧化作用，朽烂是油脂过氧化反应措施，并且等离子、体液或者简单的化工解答的能力打破反应。
