全身性氧化应激被认为是导致衰老的原因。在这项研究中,估计氧化应激水平在加速老化的小鼠倾向8(SAMP 8),我们评估了血清活性氧的生产和还原能力,通过测量二羟甲基氨基甲烷(d-ROM)和生物抗氧化电位(BAP),分别与年龄。SAMP 8的d-ROM值随龄期的增加早于对照株SAM抗性1(SAMR 1)。BAP水平在SAMP 8中最高,而SAMR 1在年龄之间呈现持续的BAP值。这些结果表明SAMP 8中的氧化应激高于SAMR 1。本研究是首次对SAMP 8中d-ROM和BAP的详细报道,为今后的衰老研究提供了有用的基础数据。
Systemic oxidative stress is considered to cause aging. In this study, to estimate the oxidative stress level in senescence-accelerated mouse prone 8 (SAMP8), we evaluated serum reactive oxygen species production and reduction capacity by measurement of Diacron-Reactive Oxygen Metabolites (d-ROM) and Biological Antioxidant Potential (BAP), respectively, with age. SAMP8 showed earlier increase of d-ROM value with age than SAM resistant 1 (SAMR1), the control strain. The BAP level was the highest in adult SAMP8, whereas SAMR1 presented the sustained BAP values between ages. These results indicate that oxidative stress in SAMP8 is higher than SAMR1. Our study is the first detailed report about d-ROM and BAP in SAMP8 and will provide useful fundamental data for future aging studies.
