Sarin yog muaj zog inhibitor ntawm acetylcholinesterase, ib qho enzyme uas degrades cov neurotransmitter acetylcholine tom qab nws tso rau hauv lub synaptic cleft.
Yuav ua li cas hom inhibitor yog sarin?
Sarin yog ib qho muaj zog heev acetylcholinesterase (AchE) inhibitor nrog rau qhov tshwj xeeb thiab kev sib raug zoo rau cov enzyme. Kev tuag los ntawm sarin yog vim anoxia uas tshwm sim los ntawm txoj hlab pas txhaws, tsis muaj zog ntawm cov leeg ntawm kev ua pa, convulsions thiab ua pa tsis ua haujlwm.
Sarin cuam tshuam li cas ntawm acetylcholinesterase?
Sarin (GB, O-isopropyl methylphosphonofluoridate) yog lub zog organophosphorus (OP) cov paj hlwb uas inhibits acetylcholinesterase (AChE) irreversibly. Cov tom ntej ntawm acetylcholine (ACh) nyob rau hauv lub hauv paus paj hlwb (CNS) provokes qaug dab peg thiab, ntawm txaus koob, centrally-mediated ua pa nres
Puas paj hlwb puas yog agonist lossis antagonist?
Nws ua raws li tus antagonist rau muscarinicacetylcholine receptors, thaiv cov teebmeem ntawm acetylcholine ntau dhau. Qee cov tshuaj anticholinergics hluavtaws, xws li biperiden, tuaj yeem tiv thaiv cov tsos mob hauv nruab nrab ntawm cov paj hlwb ua rau lom tau zoo dua li atropine, vim tias lawv dhau los ntawm cov ntshav-hlwb hauv hlwb zoo dua li atropine.
Sarin siv rau dab tsi?
Sarin yog ib qho tshuaj lom neeg heev, siv hauv tshuaj riam phom thiab ua cov paj hlwb. Nws tau tshawb pom tab sis tsis siv hauv Tebchaws Yelemees thaum WWII. Cov tshuaj lom tuaj yeem ua rau tuag taus, comas, los ntshav, thiab xeev siab. Sarin yog ib qho tshuaj lom neeg heev uas siv los ua cov kab mob paj hlwb.
Pom zoo:
Leej twg yog tus receptor antagonist?
A receptor antagonist yog hom receptor ligand lossis tshuaj uas thaiv lossis ua kom cov tshuaj lom neeg los ntawm kev khi rau thiab thaiv cov receptores tsis ua kom nws zoo li tus agonist. Cov tshuaj antagonist cuam tshuam rau kev ua haujlwm ntawm cov receptor proteins .
Puas yog sarin ua rau cov hlab ntsha?
Sarin yog tib neeg tsim tshuaj tua kab mob uas tau muab cais ua tus neeg mob lub paj hlwb. Cov kab mob paj hlwb yog cov tshuaj lom tshaj plaws thiab ua haujlwm sai ntawm cov tshuaj tua kab mob uas paub txog . Cov piv txwv ntawm cov paj hlwb yog dab tsi?
Puas yog sarin gas puas tau siv?
Nws yog txiv neej tsim tshuaj lom. Sarin yog siv hauv ob qhov kev tawm tsam hauv Nyij Pooj xyoo 1994 thiab 1995 . Thaum twg sarin gas siv kawg? Lub Koom Haum rau Kev Tiv Thaiv Tshuaj Riam Phom xaus Sarin tau siv los ua riam phom nyob rau sab qab teb ntawm cov neeg ntxeev siab tuav Latamina rau 24 Lub Peb Hlis 2017, thiab tshuaj chlorine ntawm nws lub tsev kho mob tom ntej day .
Puas yog xuab zeb yog pob zeb lossis tsis yog?
Qhov tau hais tias, ob pawg tseem ceeb ntawm cov ntawv xuab zeb yog silicon carbide thiab aluminium oxide Nyob rau hauv cov pawg no muaj ntxhib thiab nplua grits muaj, tab sis nws boils mus rau dab tsi ua haujlwm. sandpaper yog siv rau. Almandine yog garnet ntxhia uas feem ntau siv los ua cov ntawv xuab zeb .
Puas yog sarin gas siv hauv Syria?
Plaub Hlis 4, 2017: Cov riam phom tshuaj tau siv hauv kev tawm tsam uas tua ntau tus neeg hauv Syria sab qaum teb Idlib xeev. Cov ntawv ceeb toom thawj zaug qhia tias qhov kev tawm tsam siv cov roj sarin,paj hlwb Qhov kev tawm tsam ntseeg tias tau ua txhaum los ntawm tsoomfwv Syrian, vim yog hom dav hlau hauv cheeb tsam thaum lub sijhawm.
