百草枯(Paraquat.PQ)为速效触杀性灭生性除草剂,对人毒性极高,中毒患者常出现多器官功能衰竭而死亡,其中肺是百草枯损伤的主要器官,如能度过急性期,后期可因不可逆的肺纤维化引起的呼吸衰竭而死亡[1],至今对其损伤机制尚未阐明,更无特效解毒剂,病死率极高(85%～95%),本文就2004 Paraquat (Paraquat.PQ) is a quick-acting, contact-killing, biocidal herbicide that causes extreme toxicity to humans and often causes multiple organ failure in patients with poisoning. The lungs are the main organs of paraquat-induced injury. The latter may be due to irreversible pulmonary fibrosis caused by respiratory failure and death [1], so far the mechanism of its damage has not yet been clarified, more effective antidote, high mortality (85% to 95%), this article on 2004
