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?
Nerve agents yog cov tshuaj uas cuam tshuam rau lub paj hlwb. Cov teebmeem kev noj qab haus huv zoo ib yam li cov uas tsim los ntawm qee cov tshuaj tua kab. Cov kab mob tseem ceeb yog cov tshuaj tshuaj sarin (GB), soman (GD), tabun (GA) thiab VXCov tshuaj no yog tib neeg tsim thiab tau tsim los siv hauv kev ua tsov rog tshuaj.
sarin gas ua dab tsi rau koj lub cev?
Kev raug tshuaj ntau ntawm sarin tuaj yeem ua rau tshee, qaug dab peg, thiab hypothermia. Qhov cuam tshuam loj dua ntawm sarin yog qhov tsim ntawm ACh hauv nruab nrab lub paj hlwb (CNS) uas ua rau tuag tes tuag taw thiab thaum kawg peripherally-mediated respiratory arrest, ua rau tuag.
Dab tsi yog cov tsos mob ntawm kev raug cov paj hlwb zoo li sarin?
tawm hws ntau (diaphoresis) thiab cov leeg pob tw (fasciculations) ntawm qhov chaw ntawm kev sib cuag, xeev siab, ntuav (emesis), raws plab, thiab qaug zog (malaise). Mob hnyav: Cov teebmeem kev noj qab haus huv tuaj yeem tshwm sim sai; 2 mus rau 30 feeb tom qab kis tau.
Puas yog sarin yog agonist lossis antagonist?
Sarin yog muaj zog inhibitor ntawm acetylcholinesterase, ib qho enzyme uas degrades cov neurotransmitter acetylcholine tom qab nws tso rau hauv lub synaptic cleft.

Puas yog cov hlab ntsha puas yog ib feem ntawm kev ua pa?
Lub tshuab ua pa thiab ua pa ua haujlwm ua ke kom xa cov ntshav thiab oxygen thoob plaws hauv lub cev. Cua txav mus rau hauv thiab tawm ntawm lub ntsws los ntawm lub trachea, bronchi, thiab bronchioles. Cov ntshav txav mus rau hauv thiab tawm ntawm lub ntsws los ntawm pulmonary arteriesthiab cov hlab ntsha uas txuas rau lub plawv .
Leej twg kos cov roj ntsha hauv cov hlab ntsha?
Yuav Ua Li Cas Kos ABG. Cov Ntshav Ntshav Ntshav yuav tsum tus kws saib xyuas neeg mob txhawm rau sau cov qauv me me ntawm cov ntshav - feem ntau, tag nrho 1 ml³ nyiam dua. Cov ntshav tuaj yeem kos los ntawm cov hlab ntsha ntawm lub dab teg, puab tais, lossis saum lub luj tshib.
Puas yog cov hlab ntsha pinched ua rau mob hauv siab?
Yog tias koj tau hno cov hlab ntsha hauv koj lub caj dab lossis pob txha caj dab, koj yuav hnov mob hauv koj lub hauv siab lossis rov qab. Kev ntxhov siab ntau dhau ntawm cov hlab ntsha tuaj yeem ua rau nws tsis ua haujlwm li nws yuav tsum tau ua.
Cov hlab me me tshaj plaws nyob rau hauv cov hlab ntsha hu ua qhov twg?
Cov hlab ntsha me tshaj plaws, hu ua capillaries, me me heev koj xav tau lub tshuab ntsuas kom pom lawv. Capillaries koom ua cov hlab ntsha loj. Qhov loj dua yog hu ua cov leeg. Cov hlab no nqa ntshav rov qab mus rau lub plawv . Cov hlab ntsha me tshaj plaws lossis cov hlab ntsha hauv cov hlab ntsha yog dab tsi?
Puas yog cov hlab ntsha hauv lub hlwb puas yog myelinated?
Txhua lub paj hlwb, tshwj tsis yog optic thiab olfactorycov hlab ntsha, uas suav tias yog qhov ncaj qha nthuav dav ntawm lub hauv nruab nrab paj hlwb, muaj thaj chaw hloov pauv ntawm nruab nrab myelin (los ntawm oligodendrocytes) thiab peripheral myelin (tsim los ntawm Schwann hlwb) .
