铝电解工神经行为、自主神经功能的改变

Alteration of neurobehavioral and autonomic nervous function in aluminum electrolytic workers

为探讨职业性铝接触对作业工人神经系统功能的损害 ,采用世界卫生组织推荐的神经行为测试组合 (NCTB)以及EwingDJ推荐的自主神经功能测试组合对铝厂电解车间 3 2名工人和 3 4名无职业性接触的面粉厂扛包工进行测试。结果表明 :铝电解工人的消极情感困惑 -迷茫和紧张 -焦虑的得分较对照组明显增加 ;而愤怒 -敌意、忧郁 -沮丧、疲惫 -惰性和有力 -好动的得分没有明显改变。数字译码数和目标追踪的打点数比对照组降低 ,而数字广度、提转捷度和视觉保留时的得分两组未见显著性差异。自主神经功能测试中反映副交感神经调节功能的R R间隔的变化能力降低。提示电解接触铝对作业工人的情感状态。

In order to explore the impairment of Aluminum on the neurobehavioral, autonomic nervous function. Neurobehavioral test battery (NCTB) recommended by WHO and autonomic nervous system (ANS) function test recommended by Ewing DJ were conducted in 32 Al electrolytic workers and 34 controls. Results showed that the scores of confusion-bewilderment and tension-anxious in Al exposed workers were higher than that of control group, while the scores of POMSA,POMSD, POMSF and POMSV in Al-exposed group had no obvious change. The scores of DSY, PA and PAC were lower than that of control group. The scores of DSPF, DDSPB, DSP, SANN,SANP and BVR had no significant alteration. R-R interval variability of max:min ratio of immediate standing up, which reflects parasympathetic nervous modification ability in aluminum electrolytic workers, was lower than that of the control group. This implied that Al exposure had adverse impact on workers' mood state, neurobehavioral and parasympathetic nervous function.
