由挥发性物质引起的神经系统疾病,十年前少有认识,近来报告增多.单一的化合物及化合物的混合物,主要为烃类,包括有机溶剂,其潜在毒性正逐步被认识.目前,一般神经病学者将外源性物质分成三组:醇类(甲醇、乙醇)、重金属和各种药物.挥发性物质引起的神经系综合征发生在意外暴露(常为职业性)和有意暴露(滥吸)等两种情况之后.挥发性物质包括芳香烃和脂肪烃、醇类、酯类、酮类、脂肪族的硝酸盐、麻醉剂、卤化溶剂和发射剂.芳香烃类:基本结构都有苯,虽苯对人体和骨髓有毒性并能麻醉动物,但未见人类神经中毒,然 Nervous system diseases caused by volatile substances have been rare since ten years ago and have been reported recently. The mixture of compounds and compounds mainly includes hydrocarbons, including organic solvents, and their potential toxicity is gradually recognized. At present, the general neuropathy Scholars put exogenous substances into three groups: alcohols (methanol, ethanol), heavy metals and various drugs. Volatile substances cause neurological syndrome occurs in the accidental exposure (often occupational) and intentional exposure (smoking) Volatile substances include aromatics and aliphatic hydrocarbons, alcohols, esters, ketones, aliphatic nitrates, anesthetics, halogenated solvents and propellants Aromatic hydrocarbons: The basic structure of benzene, though Benzene is toxic to the human body and bone marrow and can anesthetize animals, but no human neurotoxicity is found
