本文目的在于了解吸入甲醛(HCHO)对肺微粒钵P450的影响。实验用体重为150～175g的雄性SD大鼠,随机分组。设1个对照组以及0.5(居民吸入上限)、3.0(工人职业接触上限)和15ppm(致癌浓度) 3个实验组。各组设四种实验时间点(1日、4日、12周和24周)。每日
The purpose of this paper is to understand the effects of inhaling formaldehyde (HCHO) on the lung microparticle P450. Experimental Male Sprague-Dawley rats weighing 150-175 g were randomly divided into groups. One control group and three experimental groups of 0.5 (inhalation upper limit), 3.0 (upper limit of occupational exposure) and 15ppm (carcinogenic concentration) were set up. Each group set four experimental time points (1st, 4th, 12th and 24th week). daily
