香烟对草履虫的毒性研究

Toxicity of Cigarette Smoke to Paramecium aurelia

本实验模拟人的吸烟状况,测定香烟烟气对草履虫(Paramecium aurelia)的急性致死、急性生理伤害和抑制细胞繁殖率,并比较了带过滤嘴与不带过滤嘴香烟的毒性作用。结果表明同一牌号的香烟,带过滤嘴的较不带过滤嘴的毒性明显降低。

This experiment imitated the state of human smoking and determined the toxi-city of cigarette smoke,including lethal, physiological injury and cell reproduction inhibition to Paramecium aurelia. The experimental results showed that cigarettes with filter tips were lower tojicity effects than cigarettes without filter tips.
