苯对作业工人血清SOD活性影响的观察

根据作业环境条件选择１３０名工人，分为对照组、低浓度接触组和高浓度接触组，同时鼗２５史轻度苯中毒工人列为中毒组。常规方法进行周围血白细胞计数和，并对血清中ＳＯＤ活性测定。结果表明，苯中毒组白细胞数明显低于其它三组，血清ＳＯＤ活性高于对照组，ＳＯＤ活性与白细胞数呈负相关，可能因长期接触高浓度苯且反应敏感者体内自由基增多。

OBSERVATION ON EFFECT OF BENZENE ON SERA SOD' S ACTIVITIES OF EXPOSED WORKERS

According to the working environment 130 workers were divided into control group, low con centration group, and high concentration group. And 25 intoxicated workers were taken as the ben zene intoxicated group. white blood cells of workers were routinely counted. At the same time the activities of sera SOD were detected. It was showed that the numbr of WBC in benzene intoxicated group was lower than those in other three groups, while the activities of SOD in benzene intoxicat ed group were higher than those in control group. Negative correlationship existed between the WBC count and the activities of SOD. These results indicated that more radicals were formed in the into xicated workers chronically exposed to bigh concentration benzene who were allergic to Benzene.
