接触低浓度一氧化碳工人行为功能改变

Changes of Neurobehavioral Function in Workers Exposed to Carbon Monoxide (CO)

文章选择接触一氧化碳（ＣＯ）工人６１人为观察组（另选５６人作为对照组）进行了ＷＨＯ推荐的神经行为核心测试组合（ＷＨＯ－ＮＣＴＢ）研究。结果表明：接触组在情感状态、简单反应时、数字跨度、手工敏捷度、数字译码和视觉保留等项目的标准得分显著低于对照组（Ｐ＜０．０５），并且在简单反应时和手工敏捷度两项指标上存在剂量－反应关系。提示长期反复接触ＣＯ可对中枢视觉系统功能状态产生不良改变。

WHO Neurobehavioral Core Test Battery(NCTB) was studied for 61 workers exposed to CO and 56 other healthy control workers.The results showed that the standard scores of the exposed group were significantly lower than the controls in Profile of Mood States,simple reaction timedigit span,Santa Anna manual dexterity,digit symbol,Benton visual retention tests(P<005).There was dose-reponse relationships in simple reaction time and Santa Anna manual dexterity tests.It is suggested that the changs of Newro be havd function central nervous system could be caused by occupational exposur.
