本研究目的在于,在食物中以大豆蛋白替代酪蛋白,观察对小鼠寿命、老化等级评分和老化淀粉样蛋白沉积的影响。材料和方法采用快速老化小鼠品系为SAM—P/1和对照小鼠品系为SSM—R/1。6周龄小鼠在室温24±2C、12h光照/黑暗交替条件,自由进食。酪蛋白组:SAM-R/1小鼠雄11只,雌7只, The purpose of this study was to replace casein with soy protein in food and to examine the effects on mouse life, age grade score, and aging amyloid deposition. MATERIALS AND METHODS The fast-aging mouse strain was fed free of charge for the SAM-P / 1 and control mouse strains SSM-R / 1.6 week old mice at 24 ± 2 C, 12 h light / dark alternation conditions at room temperature. Casein group: SAM-R / 1 mice were male 11, female 7,
