锰作业工人神经行为功能的观察

目的研究职业性锰接触对工人神经行为的作用。方法将从事锰作业工人８９名，无职业危害接触史工人７９名，分为接触组和对照组，进行神经行为功能测试。两组行为功能测试得分采用Ｆ检验分析。结果两组间各项行为功能测试得分，接触组均劣于对照组。经统计分析，简单反应、数字跨度、数字译码和Ｂｅｎｔｏｎ视觉记忆以及目标追踪Ⅱ的测试方面有显著差异。结论锰作业对工人神经行为有一定的影响。

Observation on neural behavior of workers exposed to manganese

Objective To explore effects of professional exposure to manganese on neural behavior of workers. Methods 89 workers occupationally exposed to manganese were randomly selected as exposure group and 79 workers not occupationally exposed to any harmful factors were chosen as control group.All subjects were tested with WHO Neural - behavior Core Test Battery and analyzed using F test. Results Behavior function scores such as Simple Reaction Time, Digit Spain, Digit Symbol, Benton Visual Retention and Pursuit Aiming in the exposure group were significantly poorer than those in the control group. Conclusion There were advert effects of the neural behavior fend in workers exposed to manganese.
