Firstly, methanol (whether it enters the body by ingestion, inhalation, or absorption through the skin) can be fatal due to its CNS depressant properties in the same manner as ethanol poisoning. Secondly, in a process of toxication, it is metabolised to formic acid (which is present as the formate ion) via formaldehyde in a process initiated by the enzyme alcohol dehydrogenase in the liver. The reaction to formate proceeds completely, with no detectable formaldehyde remaining. Formate is toxic because it inhibits mitochondrial cytochrome c oxidase, causing the symptoms of hypoxia at the cellular level, and also causing metabolic acidosis among a variety of other metabolic disturbances. Fetal tissue will not tolerate methanol. 所以是甲"酸",他會抑制細胞色素C氧化酶,造成細胞缺氧的症狀,也會造成acidosis。 補充: 甲醇中毒的話補充葉酸可以促進甲酸的排泄! ------------------------------------------------------------------------------ 有其他問題可以再跟我聯絡~ 祝大家藥理考試順利~! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.46.116.10
