富砷饮水对居民神经系统的影响

Effects of high arsenic drinking water on the residents' nervous system

为了解饮水型慢性砷中毒对神经系统的影响，对长期饮用高砷水并具有砷性皮肤损害的砷中毒患者５７名和饮用非高砷水的健康人５７名进行对照（１：１配比）研究。结果发现：砷中毒患者末稍感觉异常以痛觉、温度觉、压觉减退最为明显，与其对照对比有显著性差异（Ｐ＜０．０５％）；植物神经功能损害以少汗、无汗及指甲异常（弧影消失、指甲变暗）最为明显，与其对照对比有显著性差异（Ｐ＜０．０５）。结果提示，砷中毒患者伴有不同程度的神经系统损害。

In order to study the effects of drinking water type chronic arsenic poisoning on nervous system, a control researchment is made between 57 arsenic poisoning patients with a long- term arsenic drinking water and suffering from arsenic skin lesion and 57 healthy people without any history of arsenic drinking water(1:1). The result showed that the arsenic poisoning patients had got abnormal distal sensation with obvious features of hypalgesia, abatement of temperature sensation with obvious of hypalgesia, abatement of temperature sensation and pressure abatement, which had great difference with the control(P <0.05);vegetative nerve functional lesion such as hppohidrosis, adiaphoresis and abnormal nail(characterized by disappeared lunule and darkened nail) are most noticeable,which also had great difference with the control(P < 0.05). The result implied that the arsenic poisoning patients suffered for nervous system lesion to varying degrees.
