摘要The main toxic component of tetramine is tetramethylenedisulfotetramine(TETS).It is a sulfonamide derivative without special antidote,tasteless and tasteless,with high toxicity and high mortality.[1]It was first discovered by a German scientist Hagen in 1949.Although its use has been banned worldwide due to its high toxicity and mortality rate,it is still available in certain countries and has led to cases of intentional and unintentional poisoning.Tetramine blocks γ-neurons,leading to dizziness,fatigue,nausea,vomiting,convulsions,and other symptoms.[2-4]Due to the lack of recognized effective antidotes,many poisoned people suffocate and die as a result of continuous spasms of the respiratory muscles.[5-7]Tetramine poisoning sometimes occurs,but it is rare for vegetables grown in tetramine-contaminated soil to cause group poisoning after being eaten.
