丙二醛（MDA）是血液中脂质过氧化作用的一个重要标志，血浆钢盔蛋白（CP）及谷胱甘肽（GSH）分别是胞外及胞内的抗氧化剂，红细胞抗脂质过氧化作用的保护能力依赖于氧化剂与抗氧化剂之间的平衡，作者研究了类风湿性关节炎（RA）患者血中MDA与CP和GSP之间的关系。血样来自RA患 Malondialdehyde (MDA) is an important marker of lipid peroxidation in the blood. Plasma helm protein (CP) and glutathione (GSH) are extracellular and intracellular antioxidants, respectively. Antioxidative activities of erythrocytes against lipid peroxidation The ability to protect depends on the balance between oxidants and antioxidants. The authors studied the relationship between MDA and CP and GSP in patients with rheumatoid arthritis (RA). Blood samples from RA patients
