Abstract
Natural hydrophilic antioxidant carnosine protects cerebral cytosolic Cu,Zn-superoxide dismutase (SOD) under conditions of oxidative stress in various in vivo models: short-term hypobaric hypoxia in rats and accumulation of age-related changes in senescence-accelerated mice (SAMP). Administration of carnosine preventing Cu,Zn-SOD inactivation reduced mortality in rats and prolonged average life span in SAMP-mice.
摘要
天然亲水性抗氧化剂肌肽在多种体内模型的氧化应激条件下保护大脑胞质铜锌超氧化物歧化酶（SOD）：大鼠的短期低压缺氧以及衰老加速小鼠（SAMP）中与年龄相关变化的积累。给予肌肽可防止铜锌超氧化物歧化酶失活，降低大鼠死亡率并延长SAMP小鼠的平均寿命。
