This work reviews preclinical and clinical studies published during the past two decades on the cellular and behavioral effects of commonly misused solvents. In animals, acute solvent exposure produces motor impairment and antidepressant- and anxiolytic-like effects. Human intoxication from misusing solvents is similar to that of ethanol; however, hallucinations and sudden sniffing death may occur at high solvent concentrations. Among chronic misusers, there is evidence of impaired memory, increased prevalence of psychiatric disorders, and neurological damage. Solvents facilitate inhibitory neurotransmission and block excitatory mechanisms. Toluene, in particular, increases brain dopamine levels and its effects occur at concentrations that do not dissolve cell membranes; therefore, neuronal damage is not an immediate, unavoidable consequence of solvent misuse.
这篇综述回顾了过去二十年中关于常见滥用溶剂的细胞和行为影响的临床前和临床研究。急性溶剂暴露会导致动物运动障碍以及抗抑郁和抗焦虑样效应。人类因滥用溶剂而中毒的症状与乙醇相似;然而,在高浓度的溶剂下可能会出现幻觉和突然的嗅吸致死。在慢性滥用者中,有证据表明存在记忆障碍、精神疾病患病率增加和神经损伤。溶剂促进抑制性神经传递并阻断兴奋性机制。特别是甲苯会增加大脑中的多巴胺水平,其作用发生在不溶解细胞膜的浓度下;因此,神经元损伤不是溶剂滥用的直接、不可避免的后果。
