脂质过氧化是引起膜流动性降低、机体老化和疾病发生的重要原因之一 ,而机体本身存在抗氧化剂和抗氧化酶系等保护系统 ,用以防止或终止过氧化作用〔1〕。据报道红景天具有明显抗疲劳、抗缺氧、抗衰老的作用 ,可增强机体免疫力〔2〕。本实验通过饲喂老龄小鼠红景天制剂 ,测定心 Lipid peroxidation is caused by membrane fluidity reduction, body aging and disease one of the important reasons, and the body itself, there are antioxidants and antioxidant enzymes and other protective systems to prevent or terminate the peroxide [1]. Rhodiola has been reported with significant anti-fatigue, anti-hypoxia, anti-aging effect, can enhance the body’s immune system [2].
