摘要
９２名油漆工为观察组，５７名行政人员、教师和学生为对照组，观察其白细胞计数（ＷＢＣ）、血清过氧化脂质（ＬＰＯ）含量及超氧化物歧化酶（ＳＯＤ）的活力。结果；观察组ＷＢＣ异常［低于４０００／ｍｍ３（４×１０９／Ｌ）］检出率高于对照组（Ｐ＜０．０１）；ＳＯＤ活力高于对照组（Ｐ＜０．０５），且与ＷＢＣ呈负相关。观察组中ＷＢＣ低于４０００／ｍｍ３（４×１０９／Ｌ）的人群，其血清ＳＯＤ活力高于ＷＢＣ４０００／ｍｍ３以上的人群。在ＷＢＣ高于４０００／ｍｍ３（４×１０９／Ｌ）的人群中，血清ＳＯＤ活力观察组也高于对照组。说明苯对作业工人血清中ＳＯＤ水平有影响，且比较敏感，其意义有待进一步研究。ＬＰＯ两组无差别。Ｐ＜０．０１２．３ＬＰＯ及ＳＯＤ测定结果观察组ＬＰＯ值低于对照组，但统计学处理差异无显著意义。ＳＯＤ活性观察组高于对照组，差异具有显著意义（Ｐ＜０．０５）。观察组按工龄及吸烟与否分组，各组间ＳＯＤ活性无显著性差异（表３）。表３观察组与对照组血清ＬＰＯ、ＳＯＤ测定结果比较＊ｐ＜０．０５２．４ＷＢＣ、ＬＰＯ、ＳＯＤ之间相关性分析ＳＯＤ与ＬＰＯ之间、ＷＢＣ与ＬＰＯ之间相关关系不明显（ｐ＞０．０５），而ＷＢＣ与ＳＯＤ之间呈负相?
The contents of the lipid peroxide(LPO) and the activity of superoxide dismutase(SOD) in serum and the number of white blood cells (WBC) were determined in 92painters, 57 administrators,eachers and students were also examined as the controls. The study showed that the rate of abnormal count of WBC in the exposed workers was higher than that in the control group (p<0.01) and the SOD was more active in the exposed group too(P<0.05).There was negative correlation between SOD and WBC count.The study also showed that among the exposed group, the SOD of the workers with decreased count of WBC was more active than that of those with nomal. The SOD of the workers exposed to benzene with normal count of WBC was more active than that of the controls. There were no differrences in contents of LPO between the two groups.
