Peb muabPropitocaine hydrochloride, thov xa mus rau lub vev xaib hauv qab no kom paub meej specifications thiab cov ntaub ntawv khoom.
Propivacaine hydrochloride thaiv cov paj hlwb li cas?
Propitocaine hydrochloride ua haujlwm los ntawm cov txheej txheem sophisticated los thaiv cov paj hlwb. Nyob rau theem molecular, tus neeg sawv cev tshuaj loog hauv zos no cuam tshuam nrog cov kab hluav taws xob-gated sodium hauv cov paj hlwb. Cov channel no yog qhov tseem ceeb rau tiam neeg thiab kev nthuav tawm ntawm qhov kev ua tau zoo, uas yog cov hluav taws xob impulses uas xa cov ntaub ntawv raws li paj hlwb. Los ntawm kev khi rau cov chaw tshwj xeeb ntawm cov xov tooj ntawm cov sodium, propitocaine hydrochloride tiv thaiv kev nkag mus ntawm sodium ions mus rau hauv cov hlab ntsha hlwb. Qhov no inhibition cuam tshuam cov txheej txheem depolarization ib txwm, ua rau nws nyuaj rau cov paj hlwb kom ncav cuag nws qhov pib muaj peev xwm thiab tsim kom muaj peev xwm ua tau.
Lub blockade ntawm sodium channels los ntawmPropitocaine hydrochlorideyog ob qho tib si concentration-dependent thiab siv-dependent. Cov tshuaj ntau dua ua rau muaj kev cuam tshuam ntau dua ntawm cov hlab ntsha, thaum rov ua kom cov hlab ntsha rov qab txhim kho cov nyhuv thaiv. Qhov kev siv-dependent block no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv chaw kho mob, vim nws tso cai rau kev tswj xyuas qhov mob zoo hauv cov paj hlwb uas muaj zog lossis txhawb nqa.
Selectivity nyob rau hauv Nerve Fiber Hom
Ib qho ntawm qhov zoo tshaj plaws ntawm propitocaine hydrochloride qhov kev txiav txim yog nws qhov sib txawv ntawm ntau hom paj hlwb. Qhov sib xyaw ua ke nthuav tawm qhov kev nyiam tshaj plaws ntawm cov khoom me me, unmyelinated C fibers thiab thinly myelinated Aδ fibers, uas yog lub luag haujlwm tseem ceeb rau kev kis mob thiab qhov kub thiab txias. Qhov kev xaiv no txhais tau hais tias kev hnov lus muaj kev cuam tshuam ntau dua li kev ua haujlwm ntawm lub cev muaj zog, uas feem ntau nqa los ntawm cov loj, hnyav myelinated fibers.
