本文采用WHO推荐的“神经行为核心测验组合”对61名锰铁冶炼工人及其对照组进行了神经行为功能测定。结果发现,锰铁冶炼工人由于受锰烟等的影响,即使在临床体检、脑电图、尿锰水平均正常的情况下,神经行为功能已出现改变。在扣除年龄及受教育程度对行为功能影响的前提下,其短时视记忆力,手工操作敏捷度,感如运动速度,手运动的速度,反应速度及注意力均明显下降。不少行为指标间具有相关性,显示了行为功能的内在联系。结果提示,行为功能测定在慢性锰中毒早期诊断方面,可提供定量的评价指标。
In this paper, the WHO “core behavioral core test” recommended by WHO 61 ferromanganese workers and their control group were measured neurobehavioral function. The results showed that ferromanganese smelting workers affected by manganese smoke and other effects, even in clinical examination, EEG, urinary manganese levels were normal, the neurobehavioral function has changed. Under the premise of deducting the influence of age and educational level on the function of behavior, the short-time visual memory, manual operation agility, sense of movement such as speed of movement, speed of hand movement, reaction speed and attention decreased obviously. A number of behavioral indicators have a correlation between, showing the intrinsic link of the behavioral function. The results suggest that behavioral testing can provide quantitative evaluation of early diagnosis of chronic manganese poisoning.
