吸烟与被动吸烟者有关指标的测定

Determination of Indexes Relation to Smokers and Passive Smoker

本文测定了48名吸烟者、不吸烟者呼出气CO、尿中SCN^-、柯铁尼的含量,并对13名被动吸烟者进行实验观察。其结果表明吸烟者上述指标分别为不吸烟者的4、2、5倍,吸烟者配偶与对照组间无显著差异。被动吸烟者受试前后呼出气CO与燃烟支数呈正相关、尿中柯铁尼含量明显增高,SCN^-无差异。三项测试比较呼出气CO及柯铁尼含量是评价烟草烟雾吸入较为理想的指标。

Indexes of expired carbon monoxide, urinary thiocyanatic and cotinine had been determinated in 48 smokers and nonsmo-kers in this paper, and experimental study was also carried out in 13 passiVe smo kers. The results show three indexes of the smokers were 4, 2, 5 times as high as nonsmokens respectively, while there wag no different significantly between the smo-oker's spous and control group. After having been exposured to smoking a significant correlation was found between expired carbon monoxide of the pasaive smeke-rs and the number of cigarettes burned (r = O.S695, P<0.01 ) .urinary cotinine concentration was increased,but thicyanatic level was not. Among the three indexes expired carbon monoxide and cotinine are more ideal ones for evaluating cigaret smoke expired.
