Amylase - yog dab tsi? Norma amylase nyob rau hauv cov ntshav

Amylase - dab tsi yog thiab zoo li cas yog cov kev ua ntawm lub cev? Nws yog txhais raws li ib tug tag nrho pawg ntawm cov enzymes, uas yog koom nyob rau hauv ib lub npe - "amylase". Muaj peb hom no substance: alpha, beta thiab gamma. Rau cov tib neeg lub cev yog ntawm kev tseem ceeb yog lub alpha-amylase. Nyob rau nws, peb tam sim no tham txog.

Qhov twg yog tsim?

Amylase - yog dab tsi? Lub npe ntawm no enzyme yog muab tau los ntawm Greek lo lus "amylon", uas txhais rau hauv Lavxias teb sab txhais tau tias "cov hmoov txhuv nplej". Nyob rau hauv tib neeg, lub amylase muaj nyob rau hauv ib tug xov tooj ntawm ntaub so ntswg thiab kabmob. Nws yog ib qho enzyme (hydrolase) uas cleaves lub complex carbohydrates. Lub concentration ntawm no enzyme yog haum siab nyob rau hauv lub pancreas. Nws yog tsim los ntawm acinar hlwb ntawm lub cev thiab secreted los ntawm pancreatic ciav rau hauv cov hnyuv, ntau yeej nyob rau hauv 12-duodenum. Nyob rau hauv tas li ntawd mus rau lub txiav, muaj qaub ncaug yog tseem tau coj los ua ke amylase. Muaj nyob rau hauv cov qaub ncaug enzyme initiates lub hydrolysis ntawm lub starch, txawm tias thaum cov zaub mov yog nyob rau hauv lub qhov ncauj. Yog li, lub digestive txheej txheem pib sai li sai tau raws li cov zaub mov nkag mus rau hauv lub qhov ncauj.

Amylase: tsom xam

Amylase - yog dab tsi? Yuav ua li cas los mus txiav txim rau cov theem nyob rau hauv tib neeg lub cev? Qhov tseeb hais tias tus txiav, uas tsim lub enzyme yog zoo heev nkag nrog cov ntshav. Feem ntau, ib sab ntawm lub enzyme (qhov tsawg kawg nkaus tus nqi ntawd) rau hauv cov hlab ntsha. Ntxiv mus, qhov no hydrolase, dhau los ntawm lub ob lub raum, yog tso tawm nrog rau cov zis.

Alpha-amylase ntshav - yog dab tsi? Yog xav paub ntxiv nyob rau hauv no tham hauv qab no.

Thaum tus Tswv txib tsom xam?

Nws yuav pab ntsuam xyuas hauv lub xeev ntawm lub cev mus kuaj ntshav. Amylase - uas yog, nyob rau hauv dab tsi kab mob nws yog nyob rau hauv cov ntshav nce? Alpha-amylase theem nyob rau hauv cov ntshav ntshav yuav muab ntau zog los ntawm ob peb lub sij hawm nyob rau hauv cov nram no pathologies:

1. Mob los yog mob pancreatitis nyob rau hauv mob.
2. Focal pancreatic necrosis.
3. Oncology txiav.
4. Gallstones (xaiv nyob rau hauv lub xub ntiag ntawm concretions nyob rau hauv lub ductal system).
5. Mob hnyuv tws.
6. Raum insufficiency.
7. Mob plab los ntshav.
8. Ileus.
9. Alcoholism thiab haus dej haus cawv qaug cawv.
10. AIDS.
11. Viral kab mob siab.
12. Mumps.
13. Sarcoidosis.
14. Typhoid fever.
15. Abdominal poob plig (sab sauv seem).

Alpha-amylase theem uas nws txo qis los yog tsis yog txiav txim nyob rau hauv cov ntaub ntawv ntawm tag nrho cov necrosis ntawm lub pancreas, nyob rau hauv Oncology tias lub cev 4 theem, txij li thaum caj pas nqaij yog hloov nrog qog, thiab cystic fibrosis (congenital tsis meej). Thaum lub sij hawm kev phais thaum muab tshem tawm ib tug tseem ceeb feem caj pas amylase theem kuj yuav txo sharply.

Nyob rau hauv dab tsi tej yam kev mob yog nce amylase nyob rau hauv cov ntshav?

Amylase ntshav - dab tsi yog nws thiab yuav ua li cas hloov no parameter nyob rau hauv pathologies ntawm lub pancreas? Nyob rau hauv mob pancreatitis nws ruaj tsub kom tsis pub dhau 4-6 xuab moos tom qab cov tsos mob pib thiab tseem nyob rau ntawm ib theem siab mus txog tsib hnub. Ua lub enzyme ua si ntawm amylase nyob rau hauv cov ntshav ntshav tsis feem ntau yog nyob ntawm seb heev ntawm tus kab mob no. Feem ntau cov feem ntau cov lus rov. Thaum puas tsuaj ntawm pancreatic tseem ceeb nce nyob rau hauv lub concentration ntawm pancreatic alpha-amylase kev ua si muaj cai. Ib qho kev nce rau hauv nws cov theem tej zaum yuav qhia ib tug muaj zog tawm los ntawm amylase nyob rau hauv cov hlab ntsha.

Nyob rau hauv tej rooj plaub tej zaum yuav muaj ib qho kev nce rau hauv nws cov concentration hauv cov ntshav? Feem ntau, qhov no yuav pom nyob rau hauv cov nram no tej yam kev mob:

1. Hypersecretion ntawm pancreatic kua txiv.
2. Kev ua txhaum tag nrho cov outflow ntawm pancreatic secretion los ntawm pancreatic ducts 12 duodenum.
3. Pancreatic mob nws tus kheej los yog nyob ze thereto kabmob. Qhov kub nce kub lug hauv nrog cev thiab cov ntshav yuav khiav tau neeg nyob tomqab sawvdaws yuav tsub kom, thiaj li muaj lub amplified zis hauv lub enzyme nyob rau hauv cov ntshav.
4. pancreatic raug mob.
5. Kev ua txhaum ntawm kev noj haus thiab haus dej haus cawv kev tsim txom.

zis diastase

Thaum glomerular filtration tas amylase, ib nrab ntawm nws yog reabsorbed tubules. Qhov seem ib nrab yog faib nyob rau hauv cov zis. Ua zis diastase cai nyob rau hauv tib tej yam kev mob raws li qhov kev nce rau hauv nws cov concentration hauv cov ntshav. Nws yuav tsum tau muab sau tseg tias amylase kev ua si nyob rau hauv cov zis yog kwv yees li 10 lub sij hawm ntau tshaj li nws cov kev ua si nyob rau hauv cov ntshav.

Amylase - dab tsi yog nws thiab dab tsi yog qhov permissible txwv ntawm qhov ntsuas no nyob rau hauv cov ntshav thiab zis? Qhov no yuav tsum tau tham ntxiv.

Alpha-amylase - yog dab tsi? Qhov tseem ceeb nyob rau hauv cov ntshav thiab zis

Thaum nyeem ntawv cov kev tshwm sim ntawm tus tsom xam rau cov amylase yuav tsum xyuam xim rau dab tsi units nws yog expressed. Nws yog txoj kev cai uas siv cov "U / L" - amylase units ib liter ntawm cov ntshav thiab "mkkatal / l" - mikrokatal ib liter. Nws yuav tsum tau ua kom meej hais tias lub "dov" - ib tug tsev los ntsuas cov kev ua ntawm lub hauv paus.

Tsis tas li ntawd, nyob rau hauv txawv lub chaw soj nstuam txoj kev thiab reagents txiav txim seb lub amylase tej zaum yuav ib nyuag txawv, yog li ntawd koj yuav tsum xyuam xim rau cov kev cai ntawm qhov ntsuas no, uas yog yeej ib txwm qhia tom ntej no mus rau lub txiaj ntsim ntawm kev tshawb xyuas. Tus thawj daim duab - yog qhov tsawg kawg nkaus tus nqi, tus thib ob - lub siab tshaj plaws.

Standards alpha-amylase ntshav thiab zis diastase yog muab nyob rau hauv lub rooj hauv qab no:

Nyob rau hauv tus neeg mob qhov twg muaj ib tug me ntsis nce nyob rau hauv kev kawm (ntau chav nyob) thiab cov neeg zoo zoo, qhov no yog tsis yog ib tug pathology. Txhawj thaum koj xav tau kom amylase qhov tseem ceeb ob peb lub sij hawm. Tawm tsam ntawm mob pancreatitis kuj yuav ua ib qho kev nce ntawm diastase ntshav thiab zis amylase rau 100 lub sij hawm los yog ntau tshaj. Feem ntau, cov tawm tsam yog nrog xeev siab, ntuav thiab mob heev. Qhov no mob yuav tsum tau tam sim ntawd pw tsev kho mob.

Yuav ua li cas yuav tsum tau mus soj ntsuam rau cov ntshav thiab zis amylase?

Cov ntshav ntawm no tsom xam yog coj los ntawm cov hlab ntsha. Feem ntau nws zaum nyob rau hauv thaum sawv ntxov nyob rau ib npliag plab, tab sis, yog hais tias koj xav tau rau urgently txiav txim rau theem ntawm kev amylase, piv txwv li, ib tug exacerbation ntawm tus kab mob pancreatitis, nws yuav ua tau nyob rau txhua lub sij hawm. Xws li ib tug tsom xam yuav ua tau tej biochemical kev kuaj. Feem ntau, nyob rau hauv modern laboratories siv enzymatic diagnostic txoj kev amylase kev ua si. Nws yog ib tug meej thiab leej txoj kev. Analysis yog ua sai sai txaus.

Analysis ntawm cov zis diastase yog qhov zoo tshaj rau noj thaum sawv ntxov. Siv qhov nruab nrab ntawm cov zis thiab tam sim ntawd thauj mus rau hauv txoj kev kuaj. Kev tshawb fawb ntawm no daim duab yog ntawm kuj zoo kawg tseem ceeb nyob rau hauv qhov mob ntawm ntau yam kab mob.
