甲醛属于有害气体,其水溶液和蒸气具有强烈的毒性和刺激性,长期与甲醛接触,对机体究竟有多大影响,是解剖工作者关心的问题。为此,我们用小白鼠做实验,进行了210天的观察,情况如下: 材料和方法雄性小白鼠40只,体重26—27克,分成四组,第一组(5只)、第二组(5只)、第三组(15只)为实验组;第四组(15只)为对照组。分别给第一、二、三组小白鼠吸入430mg/m~3、90mg/m~3、7—9 mg/m~3的甲醛蒸气,每天染毒2小时。于染毒90天,

Formaldehyde is a harmful gas, its aqueous solution and steam has a strong toxicity and irritation, long-term contact with formaldehyde, how much impact on the body, is anatomical concern. For this purpose, we performed experiments with mice for 210 days. The data were as follows: Materials and Methods Forty male mice weighing 26-27 g were divided into four groups, the first group (n = 5), the second group (5), the third group (15) for the experimental group; the fourth group (15) for the control group. The first, second and third groups of mice were inhaled 430mg / m ~ 3, 90mg / m ~ 3, 7-9 mg / m ~ 3 formaldehyde vapor, respectively, for 2 hours. 90 days after exposure,
