Therefore, based on documents reports, through contrastive observation of 20-month-old natural senile mice, this study has confirmed that the anaplasia of subacute senile model mice was obviously similar to the features of 20-month-old naturally physiological senile mice. Mice in both two groups displayed dull color patterns, slow movements, insensitive responses and decrease of growth rates of body weight; hepatic and brain tissues in the mice presented senile features of sero-enzyme such as decrease in SOD activity, increase in content of lipid perhydrides and so on.

为此，本研究在文献报道基础上，通过与20月龄自然老化鼠的对比观察，证实：亚急性衰老模型鼠的退行性变化与20月龄自然生理性老化鼠特征的相近之处鲜明可见。2组均出现毛色暗淡，少有光泽，动作迟缓，反应不灵敏，体重增长率下降；肝、脑组织出现SOD活力下降，脂质过氧化物含量增高等血清酶学的老化特征。
