Angiotensin-hloov enzyme yog ib yam khoom siv lom neeg muaj nyob hauv tib neeg lub cev thiab koom nrog ntau yam kev xav ntawm lub cev. Hauv particular, nws tswj cov dej-ntsev metabolism thiab tswj cov ntshav siab los ntawm kev txwv lossis nthuav cov hlab ntsha. Yog li ntawd, nws yog ib qho tseem ceeb heev los tswj nws txoj hauj lwm, tshwj xeeb tshaj yog rau cov neeg laus, vim hais tias lawv yog cov uas raug kev txom nyem tshaj plaws los ntawm cov ntshav siab thiab nws cov rhiab heev.

Cov ntaub ntawv dav dav txog ACE

Angiotensin-hloov enzyme yog nquag koom nrog hauv cov metabolism. Nws ua qhov no los ntawm kev cuam tshuam lub npe hu ua renin-angiotensin system, uas yog lub luag haujlwm rau kev tswj ntshav siab.

Lub tshuab ua haujlwm ntawm enzyme yog qhov nyuaj heev. Yog tias peb piav qhia hauv cov ntsiab lus, nws muaj nyob rau hauv kev cuam tshuam cov txheej txheem ntawm kev hloov angiotensin-I rau hauv angiotensin-II, uas muaj cov khoom siv roj ntsha. Tshwj xeeb, nws ncaj qha cuam tshuam rau qibntshav siab thiab pab txhawb rau nws nce, constricting cov hlab ntsha. Nws yog vim nws txoj haujlwm tseem ceeb ntawm kev hloov ib qho angiotensin mus rau lwm qhov uas cov enzyme tau tham hauv kab lus tau txais nws lub npe.

Yog tias peb tham txog qhov twg angiotensin-hloov enzyme tsim, ces muaj ob qhov chaw tseem ceeb rau nws cov synthesis hauv lub cev: lub ntsws cov ntaub so ntswg (qhov chaw tseem ceeb ntawm qhov tsos) thiab lub raum tubules (hauv me me). Tom qab synthesis, cov khoom sib npaug sib npaug hauv yuav luag tag nrho cov ntaub so ntswg ntawm lub cev.

Qhia rau kev kuaj mob ua haujlwm

Raws li qib ntawm angiotensin-hloov enzyme kev ua haujlwm, cov kws tshaj lij txiav txim siab tias muaj qee yam kab mob, tsis yog txhua yam cuam tshuam nrog ntshav siab. Peb tuaj yeem tham txog cov kab mob xws li:

  • Sarcoidosis.
  • kab mob ua pa xws li bronchitis thiab pulmonary fibrosis.
  • Rheumatoid mob caj dab.
  • mob siab lossis mob raum.
  • Amyloidosis.
  • Kab mob ntshav qab zib mellitus thiab lwm yam

Qee zaum, kev tshuaj xyuas tau raug tshuaj xyuas los saib xyuas cov txiaj ntsig ntawm angiotensin-hloov pauv enzyme inhibitors. Qhov no tsis tshua muaj, tab sis rau tus neeg mob uas nws txoj kev noj qab haus huv tuaj yeem nyob ntawm cov tshuaj hauv pab pawg no, kev tshuaj xyuas dhau los ua cov txheej txheem kuaj mob tseem ceeb heev.

Angiotensin-hloov tshuaj enzyme

ACE inhibitors yog pab pawg neeg nyiam tshaj plaws ntawm cov tshuaj siv rautswj siab los ntawm cov neeg thoob ntiaj teb. Lawv yog ob qho tib si tshuaj rau kev kho mob xwm txheej ceev ("Captopril") thiab cov tshuaj kho mob ("Enalapril", "Lizinopril"). Lub ntsiab lus ntawm lawv qhov kev ua yog tias lawv ua kom qeeb ntawm kev tsim khoom thiab cov nyhuv ntawm ACE ntawm angiotensin-I, tiv thaiv nws los ntawm kev hloov mus rau hauv daim ntawv nquag thiab, raws li, tiv thaiv kev nce ntshav siab.

Npaj rau kev kawm

Angiotensin converting enzyme test tsis tas yuav muaj cov kauj ruam npaj loj. Cov enzyme tau txiav txim siab hauv cov ntshav venous, yog li kev npaj rau kev kuaj ntshav yog ua raws li cov lus pom zoo rau ib qho kev kawm:

  • Tus neeg mob tsuas yog muab cov ntshav rau ntawm lub plab khoob xwb, thiab yog li ntawd nws raug nquahu kom tsis txhob noj 12 teev ua ntej mus rau chav kuaj ntshav.
  • Nws yog ib qho tsim nyog kom tsis txhob haus luam yeeb thiab haus cawv ib hnub ua ntej kuaj ntshav, vim tias cov tshuaj no tuaj yeem cuam tshuam rau qib ntawm enzyme.
  • Kev ntxhov siab yuav tsum zam, vim tias qhov kev cuam tshuam rau kev ntxhov siab tuaj yeem cuam tshuam rau ntau lub cev ua haujlwm, piv txwv li, ua rau muaj kev cuam tshuam ntawm ACE ntawm lub siab.

Thaum twg yog theem ntawm ACE nce

Thaum tus neeg mob tsim cov kab mob uas tau piav qhia saum toj no (sarcoidosis, kab mob ua pa), tus nqi ntawm angiotensin-hloov enzyme hauv cov ntshav nce ntau. Txawm li cas los xij, sarcoidosis tam sim no yog qhov laj thawj rau kev sim.

Qhov tseeb etiology ntawm tus kab mob tseem tsis paub meej, tab sis nws paub tias thaum sarcoidosis tshwm sim, ACE-tsim granulomas pib tshwm hauv cov qog ntshav. Kev nce qib ntawm cov enzyme tuaj yeem raug sau tseg thiab siv los ua kev kuaj mob hauv kev txheeb xyuas tus kabmob.

Nrog rau qhov sib txawv tseem ceeb ntawm qib ACE nce siab, tus kws kho mob tau sau cov txheej txheem kuaj mob ntxiv kom paub meej lossis tsis lees paub qhov kev kuaj mob. Yog li ntawd, nyob rau hauv lub hauv paus ntawm tsuas yog ib qho kev soj ntsuam, nws yog tsis yooj yim sua kom paub meej seb tus neeg mob puas muaj xws li ib tug kab mob loj li sarcoidosis.

Angiotensin-hloov enzyme norm

txhawm rau txhais cov txiaj ntsig ntawm kev tshuaj ntsuam, nws yog qhov yuav tsum tau paub txog cov txiaj ntsig ib txwm muaj rau cov enzyme. Kev tshuaj xyuas yuav tsum pom cov txiaj ntsig tau tshwm sim hauv U / L.

Cov qauv ntawm cov enzyme hauv cov neeg mob ntawm cov hnub nyoog sib txawv yog txawv. Tus nqi rau cov menyuam yaus hnub nyoog qis dua 12 xyoos yog los ntawm 9.4 txog 37 units / l. Cov tub ntxhais hluas hnub nyoog 13-16 xyoo twb muaj me ntsis ACE hauv cov ntshav. Rau lawv, tus qauv yog los ntawm 9.0 mus rau 33.4 units / l. Rau cov neeg laus, qhov tseem ceeb ntawm 6.1 txog 26.6 units / l yog suav tias yog qhov ntsuas zoo.

Puas yog qib ACE siab ib txwm yog tus cim ntawm tus mob hnyav

Cov lus teb rau lo lus nug no nyob ntawm seb tus nqi nce npaum li cas. Nyob rau hauv cov ntaub ntawv ntawm sarcoidosis, ACE yog ho nce, txij li thaum granulomas nquag tsim nws nyob rau hauv lub cev. Kev nce me ntsis tuaj yeem txhais tau tias muaj nyob hauv lub cev ntawm cov kab mob ntawm txoj hlab ntsws (xws li bronchitis), rheumatoid mob caj dab,ntshav qab zib thiab ntau yam kab mob. Nws yog ib qho tseem ceeb kom paub tias qib ACE tsis yog tib qho laj thawj uas tus kws kho mob txiav txim siab pom muaj tus kab mob tshwj xeeb.

Txhua tus neeg mob uas nws qhov txiaj ntsig ntawm qhov ntsuas no siab dhau yuav tsum tau kuaj xyuas tshwj xeeb ntxiv. Nrog kev pab los ntawm cov kev tshawb fawb no, cov kws kho mob ua qhov kev kuaj mob zaum kawg.

Vim li cas qib ntawm enzyme kev ua haujlwm tuaj yeem nce ntxiv

Nyob ntev, cov kws kho mob tsis tuaj yeem txheeb xyuas qhov tseeb vim li cas qee tus neeg muaj qib ACE ntau dhau, thaum lwm tus tsis muaj teeb meem nrog cov enzyme no.

Txawm li cas los xij, kev tshawb fawb caj ces tsis ntev los no hauv cov kev taw qhia no tau nthuav tawm cov noob rau angiotensin-hloov enzyme. Qhov no yog lub npe hu ua ACE noob, uas tshwm sim vim muaj kev hloov pauv me me thiab ua rau muaj kev sib txuas ntawm ACE hauv lub cev.

Cov noob no ua rau pom qhov tsis zoo ntawm cov ntshav siab hauv tib neeg nkaus xwb, tab sis kuj muaj ntau yam kab mob plawv. Qhov no pathology tuaj yeem tshwm sim txhua lub hnub nyoog. Txawm li cas los xij, cov kws tshawb fawb tau ceev faj heev los txiav txim siab los ntawm lawv qhov kev tshawb pom, raws li kev sim rov ua dua tau muab cov ntaub ntawv tsis sib haum xeeb.

Tshwj xeeb, qee cov kws tshawb fawb pom muaj kev vam khom ntawm qib ACE ntawm poj niam txiv neej lossis haiv neeg, thaum lwm tus tsis qhia txog kev sib raug zoo li no. Yog li ntawd, cov kws tshawb fawb qhia tias kom tau txais kev tshawb fawb tau tseeb dua, yuav tsum muaj cov txheej txheem ntxiv los lim tawm yam uas cuam tshuam rau qhov kev sim.

Tab sis qhov teeb meem nrog cov txiaj ntsig raug tsis txo qis kev cia siab tias tsis ntev cov laj thawj ntawm kev nce hauv angiotensin-hloov enzyme hauv tib neeg lub cev yuav qhia meej. Tej zaum yav tom ntej, kev kho noob yuav pab tib neeg hauv kev kho cov kab mob xws li arterial hypertension thiab angina pectoris. Nyob rau theem tam sim no, cov kab mob no tsuas yog kho nrog cov tsos mob. Yog tias qhov ua rau nce ntshav ntawm ACE tuaj yeem txheeb xyuas tau, cov neeg mob tuaj yeem tshem tawm lawv cov teeb meem nrog kev kho mob luv luv.
