美国加州大学的莫兹博士选了40只老鼠分成8组,其中两组放在清新空气环境中,用电动滚筒迫其跑步,余6组放在污浊空气环境中做程度不同的跑步运动。经解剖发现,清新空气中的老鼠肺部无损伤,肺泡结构完好。两组在污染空气中静坐不动的老鼠肺泡壁呈不正常的肥厚现象。其余4组在污染空气中运动的老鼠情况大为不妙。只做轻微活动的两组,肺部出现损伤的为静坐组的5倍,而剧烈活动的两组竟
Dr. Moose from the University of California, USA, selected 40 mice and divided them into 8 groups. Two of them were placed in a fresh air environment and were forced to run by a motorized drum. The remaining 6 groups were placed in a running environment with varying degrees of air pollution. The anatomy found that the lungs of mice in fresh air without damage, alveolar structure intact. Two groups of rats in the air pollution sit idle alveolar wall showed abnormal hypertrophy. The remaining four groups of mice that moved in contaminated air were far less well informed. Only minor activities of the two groups, the lung injury was 5 times the sedentary group, while the two groups were actually violent activities
