Lub cev "sib ntaus los yog ya" cov tshuaj tiv thaiv nyob ntawm cov tshuaj hormones thiab neurotransmitter epinephrine, ntxiv rau hu ua adrenaline. Thaum xa tawm, adrenaline tso tawm cov lus teb sib txawv ntawm lub cev uas npaj rau kev ua haujlwm nrawm. Cov hlab ntsha dilated, nce ntshav qabzib, lub plawv dhia nrawm dua thiab muaj zog ntau dua ntawm kev cog lus, thiab txhim kho cov ntshav rau cov leeg pob txha yog cov teebmeem no.Epinephrine Hcl hmoovkuj tseem ua rau cov menyuam kawm ntawv loj, ua rau hws ntau dua, thiab txo cov ntshav ntws mus rau cov kabmob uas tsis tseem ceeb.. Kev lag luam kws kho mob tso siab rau cov hmoov hmoov ntawm epinephrine hydrochloride (HCl), uas yog siv rau hauv ntau cov txheej txheem kho mob. Nkag siab txog kev ua haujlwm ntawm lub cev ntawm epinephrine yog qhov tseem ceeb rau cov kws kho mob, cov kws tshawb fawb, thiab lwm tus neeg koom nrog hauv kev tsim thiab kev tswj hwm ntawm cov tshuaj tsis raug cai raws li epinephrine.
Peb muabEpinephrine Hcl hmoov, thov xa mus rau lub vev xaib hauv qab no kom paub meej cov lus qhia tshwj xeeb thiab cov ntaub ntawv khoom.
Cov teebmeem ntawm lub plawv ntawm Epinephrine
Heart Rate thiab Contractility
Cov hlab plawv system yog ho raug mob los ntawmepinephrine Hcl hmoov. Ua kom lub plawv dhia thiab contractility yog ib qho ntawm nws cov kev cuam tshuam tseem ceeb. Lub plawv cog lus nrog ntau zog thiab ceev thaum epinephrine txuas rau nws 1-adrenergic receptors, teeb tsa cov txheej txheem ntau. Nyob rau lub sijhawm kev ntxhov siab lossis kev ua si lub cev, qhov kev ua si no yuav tsum nqus cov ntshav ntau dua, ua kom cov hlab ntsha tseem ceeb tau txais cov pa roj oxygen txaus thiab cov as-ham.
Txoj Cai Ntshav Siab
Lub peev xwm ntawm adrenaline rau kev tswj ntshav siab yog lwm qhov tseem ceeb ntawm cov hlab plawv. Nrog rau lub hom phiaj los txhawb cov kab mob vascular tsis kam, epinephrine tsim vasoconstriction los ntawm kev ua raws li cov hlab ntsha 1-adrenergic receptors. Cov ntshav siab nce siab vim qhov kev ua haujlwm no thiab ua rau lub plawv dhia ntau ntxiv. Txawm li cas los xij, thaum lub sij hawm muaj kev ntxhov siab, adrenaline kuj muaj vasodilatory los ntawm qee cov hlab ntsha, tshwj xeeb tshaj yog cov pub cov leeg pob txha, uas pab tswj cov ntshav ntws mus rau qhov chaw uas xav tau tshaj plaws.
Coronary Ntshav Flow
Qhov tseeb tias adrenaline cuam tshuam rau cov ntshav coronary yog qhov txaus nyiam. Thaum nws tuaj yeem tsim cov vasoconstriction hauv qee cov hlab ntsha, nws feem ntau ua rau cov hlab ntsha coronary kom loj, ua rau cov ntshav ntws mus rau lub plawv cov leeg. Cov txheej txheem no tseem ceeb heev thaum lub sij hawm muaj kev xav tau siab vim nws ua kom lub plawv nws tus kheej tau txais cov as-ham txaus thiab oxygen los ua nws txoj haujlwm siab.
Ua pa cuam tshuam
1.Bronchodilation
- Bronchodilation yog ib qho ntawm cov teebmeem tseem ceeb tshaj plaws ntawm epinephrine rau ntawm lub ntsws. Lub bronchi thiab bronchioles dilate raws li qhov tshwm sim ntawm kev so ntawm cov leeg du ntawm cov hlab ntsws los ntawm epinephrine txoj kev khi rau 2-adrenergic receptors. Vim tias txoj hlab ntsws tuaj yeem ua rau tuag taus hauv cov xwm txheej xws li mob hawb pob thiab anaphylaxis, qhov haujlwm no tseem ceeb heev. Epinephrine's bronchodilatory action ua kom yooj yim ua pa thiab ua pa zoo dua.
2. Tus nqi ua pa
- Epinephrine Hcl hmoovplays lub luag haujlwm tseem ceeb hauv lub cev "sib ntaus sib tua lossis ya" cov lus teb, ua rau muaj feem cuam tshuam rau kev ua pa los ntawm kev ua pa ntau zaus. Qhov kev ua pa siab no ua tau raws li lub cev xav tau oxygen ntau ntxiv thaum muaj kev ntxhov siab lossis txaus ntshai, ua kom muaj txiaj ntsig zoo ntawm cov metabolism. Nrog rau bronchodilation, uas qhib txoj hlab pa, qhov ua pa siab ua pa ua rau cov pa pauv pauv hauv lub ntsws. Raws li qhov tshwm sim, lub cev tuaj yeem muab cov pa oxygen rau cov kabmob tseem ceeb thiab cov ntaub so ntswg thaum tshem tawm cov pa roj carbon dioxide, npaj tus neeg rau lub cev sai. Qhov kev hloov pauv ntawm lub cev no qhia txog qhov tseem ceeb ntawm epinephrine hauv kev ua kom lub cev tuaj yeem teb tau zoo rau cov kev hem thawj tam sim lossis teeb meem.
3.Mucus Production
- Txawm hais tias tsawg tshaj li nws cov teebmeem ntawm bronchodilation thiab ua pa, epinephrine tuaj yeem cuam tshuam cov hnoos qeev hauv cov hlab ntsws. Feem ntau, nws zoo li txo cov hnoos qeev, uas tuaj yeem pab tswj cov hlab ntsha ntshiab. Qhov kev ua no, ua ke nrog bronchodilation, pab txhawb kev txhim kho cov pa thiab ua pa ua pa thaum lub sij hawm muaj kev ntxhov siab lossis teb rau cov teeb meem ua pa.
Glucose Metabolism
Metabolic thiab lwm yam kev cuam tshuam
- Epinephrine Hcl hmoovtswj cov ntshav qab zib thiab muaj zog cuam tshuam cov metabolism hauv qabzib thaum muaj kev ntxhov siab. Nws tso cov piam thaj rau hauv cov hlab ntsha los ntawm kev rhuav tshem lub siab glycogen reserves. Lub caij no, gluconeogenesis-kev tsim cov kua nplaum tshiab los ntawm cov khoom tsis-carbohydrate-yog nrawm los ntawm adrenaline. Cov ntshav qabzib cov ntshav tau cuam tshuam los ntawm cov txheej txheem no, yog li ua rau nws yooj yim dua rau lub cev cov hlwb kom haus lub zog thaum nws xav tau.
Lipolysis thiab Thermogenesis
- Lipolysis, rhuav tshem cov roj deposits, yog ib qho tseem ceeb metabolic nyhuv ntawm adrenaline. Epinephrine nkoos cov tshuaj hormone-rhiab heev li lipase, pab txhawb kev tso tawm ntawm fatty acids los ntawm cov ntaub so ntswg adipose. Cov fatty acids no ua lub zog tseem ceeb rau ntau cov ntaub so ntswg, txhim kho tag nrho cov metabolic efficiency. Tsis tas li ntawd, epinephrine txhawb nqa thermogenesis, ua kom lub cev muaj peev xwm ua kom sov. Cov txheej txheem no tshwj xeeb yog tshwm sim hauv cov ntaub so ntswg adipose xim av, uas yog tshwj xeeb rau kev tsim hluav taws xob. Los ntawm kev nce kev siv hluav taws xob thiab pab tswj qhov kub thiab txias, adrenaline ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis thaum muaj kev ntxhov siab, ua kom lub cev tuaj yeem ua tau raws li qhov xav tau ntawm lub zog siab thaum tseem tswj hwm qhov kub thiab txias.
Lwm yam teebmeem
- Epinephrine ua rau ob peb lwm yam teebmeem hauv lub cev. Nws ua rau cov menyuam kawm ntawv dilation, txhim kho qhov pom kev pom nyob rau hauv qhov chaw qis. Epinephrine kuj nce hws, uas pab tswj lub cev kub thaum muaj kev ntxhov siab lossis kev tawm dag zog lub cev. Nyob rau hauv lub plab zom mov, nws feem ntau txo qis motility thiab secretions, redirecting ntshav txaus thiab lub zog mus rau ntau yam tseem ceeb systems thaum lub sij hawm kev nyuaj siab teb. Tsis tas li ntawd, epinephrine tuaj yeem cuam tshuam rau kev paub txog kev ua haujlwm, txhim kho kev ceeb toom thiab ua kom pom tseeb, uas yog qhov tseem ceeb rau cov lus teb "sib ntaus lossis ya".
- Hauv kev xaus, epinephrine ua rau muaj ntau yam ntawm lub cev ua haujlwm uas npaj lub cev rau kev ua tam sim thiab kev ntxhov siab. Los ntawm nws cov kev cuam tshuam loj heev ntawm cov hlab plawv thiab cov hlab ntsws rau nws lub zog ntawm cov metabolism thiab lwm yam kev ua haujlwm, epinephrine ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis thaum muaj teeb meem nyuaj. Kev nkag siab txog cov kev ua no yog qhov tseem ceeb rau cov kws kho mob thiab cov kws tshawb fawb ua haujlwm nrog epinephrine thiab nws cov txiaj ntsig, xws liEpinephrine Hcl hmoov. Raws li kev tshawb fawb hauv daim teb no txuas ntxiv mus, peb tuaj yeem nthuav tawm cov ntsiab lus tseem ceeb ntxiv txog lub cev kev ua haujlwm ntawm cov tshuaj hormones zoo kawg li no thiab neurotransmitter. Thov koj xav tiv tauj peb ntawmSales@bloomtechz.comrau cov lus qhia ntxiv txog cov khoom siv tshuaj.
