We investigated pulmonary function and histological changes of old or young AM-KO mice correspondent with its littermate control. RV and RV/TLC of old mice were significantly increased compared with that of young mice. Mean linear intercept (Lm) of old mice was significantly increased than that of young mice. Mean alveolar area and destructive index (DI) were not significantly increased. AM gene modification did not have any effect on these indexes.

我们研究了与其同窝对照的老年或年轻 AM-KO 小鼠的肺功能和组织学变化。老年小鼠的RV和RV/TLC较年轻小鼠显着增加。老年小鼠的平均线性截距（Lm）显着高于年轻小鼠。平均肺泡面积和破坏指数（DI）没有显着增加。 AM基因修饰对这些指标没有任何影响。
