1972年伊拉克甲基汞中毒事故是一种急性大量甲基汞的作用,而日本水俣等地发生的该种中毒是较慢性的蓄积,但二者的中毒体征和症状相同。最早期的症状包括感觉异常和疲劳。较严重的中枢神经系损害为运动失调,发音困难,吞咽困难和视野缩小。并且,症状的发生率与血汞浓度呈现相关。由于中毒的早期症状与周围性多发性神经炎相似,而电生理技术又有助于后者的诊断,故作者以此种技术来研究甲基汞中毒患者的周围神经系统。对14例患者在停止汞接触后7个月
In 1972, the methylmercury poisoning accident in Iraq was an acute and large-scale role of methylmercury. However, the poisoning caused by such poisoning in Japan’s Minamata is a more chronic accumulation, but the poisoning signs and symptoms were the same in both places. The earliest symptoms include sensory abnormalities and fatigue. The more severe central nervous system damage is dyskinesia, dysarthria, dysphagia and narrowing of the field of vision. And, the incidence of symptoms correlated with blood mercury levels. Since the early signs of poisoning are similar to those of peripheral polyneuritis, and electrophysiological techniques contribute to the latter’s diagnosis, the authors used this technique to study the peripheral nervous system of patients with methylmercury poisoning. Fourteen patients were stopped 7 months after mercury exposure
