科普專欄–薯不揀單 - 深入淺出–俄國神經毒素Novichok

2018年3月，前俄羅斯間謀Sergei Skripai及其女兒在英國被人下毒，毒藥被證實為蘇聯在冷戰時期所研發的神經毒素Novichok。923Please respect copyright.ＰＥＮＡＮＡgZLYX3MUiX

2020年8月20日，一名極力反對普京的社會領袖Alexei Navalny，亦遭受到同類型的毒素傷害，表面證據暫時相信為被人在茶裡下毒。923Please respect copyright.ＰＥＮＡＮＡR7UHk9j6So

本篇深入淺出，將會簡述神經系統的運作，以及神經毒素Novichok的機制。923Please respect copyright.ＰＥＮＡＮＡw3LnBm4plZ

（圖1）神經線負責傳遞信息，為身體內的橋樑。橋樑並不是緊密相扣著的，一條神經線質另一條神經線互相均有著一道空隙。923Please respect copyright.ＰＥＮＡＮＡKvsTBlkBtw

（圖2）訊息在神經線中主要是以電流的方式傳遞。923Please respect copyright.ＰＥＮＡＮＡTi3EopzXNV
923Please respect copyright.ＰＥＮＡＮＡ5ApPEDBhJq
電流來到神經線A的末端後，便會觸發ACh釋出，使ACh來到神經線之間的空隙。923Please respect copyright.ＰＥＮＡＮＡoJs16hv570
923Please respect copyright.ＰＥＮＡＮＡQFL8NysxfR
ACh與另一神經線的Receptor結合後，便會觸發新一道的電流產生，使訊息一直能傳遞到終點。923Please respect copyright.ＰＥＮＡＮＡ93Y28ApHOR

（圖3）神經線空隙的AChE負責分解ACh，以免電流長期持續產生。923Please respect copyright.ＰＥＮＡＮＡ9AWKUltNdn
923Please respect copyright.ＰＥＮＡＮＡZqZVIfvhUe
而俄國最愛的神經毒素Novichok則會與AChE合併及抑制AChE的功能，導致ACh不會被分解，使ACh無了期與神經線的Receptor結合，長期產生神經線電流的傳播，導致患者出現抽搐、癲癇等症狀，沒能適時治療的話更會導致死亡。923Please respect copyright.ＰＥＮＡＮＡlXg3HtJWh5
923Please respect copyright.ＰＥＮＡＮＡc1a5BTLiJP
解毒劑暫時有幾種，Atropine能阻截ACh與Receptor合併，Pralidoxime能夠促使Novichok無法與AChE結合。923Please respect copyright.ＰＥＮＡＮＡUXDCON6IZ9
923Please respect copyright.ＰＥＮＡＮＡ82E905Pzm4
這些解毒劑雖然可以使患者康復起來，但患者的認知及肌肉功大有可能會有收到永久性的損害。923Please respect copyright.ＰＥＮＡＮＡVGVlKjgzLH
