Enzymes ntawm lub siab - qhov no yog ib qho tseem ceeb tshaj plaws ntawm cov txheej txheem biochemical hauv lub cev. Txij li thaum lub siab ua ntau lub zog, cov enzymes tsim los ntawm nws tau muab faib ua ntau pawg: excretory, qhia thiab secretory. Nrog ntau hom kab mob thiab kev puas siab puas ntsws hauv ntshav ntshav, cov ntsiab lus ntawm enzymes hloov. Qhov tshwm sim no yog ib qho tseem ceeb qhia tau.
Cov kab mob hauv siab puas siv los kuaj?
Enzymes ntawm lub siab, cov ntsiab lus ntawm uas tau nce nyob rau hauv cov kab mob nrog los ntawm kev puas tsuaj ntawm hepatocytes, yog hu ua qhia enzymes. Cov no suav nrog:
- glutamate dehydrogenase (Gldg);
- aspartate aminotransferase (AST);
- lactate dehydrogenase (LDH);
- gamma-glutamyltransferase (GGT);
- alanine aminotransferase (ALT).
Feem ntau, tus kab mob siab yog qhia txog ntshav kuaj rau qhov kev txiav txim siab ntawm cov ntsiab lus ntawm AST thiab ALT. Rau cov poj niam, tus qauv ntawm ACT yog 20-40 U / l. Cov mob ua rau cov neeg muaj kab mob siab los yog cov khoom ua rau cov kab mob hepatocytes, cov enzymes no ua rau muaj kev cuam tshuam ntau ntxiv.
Tus txheej txheem ntawm cov ntsiab lus ntawm daim siab enzymes ALT nyob rau hauv cov ntshav yog 12-32 U / l (poj niam). Nrog kis kab mob kev nkeeg, lawv cov kev ua si kuj nce siab - ntau ntau zaus. Hauv qhov no, qhov kev kuaj mob ntawm tus kab mob yuav tsis tuaj yeem tsis tuaj. Yog vim li ntawd, ALT feem ntau siv los kuaj xyuas kabmob siab thaum ntxov.
Lwm lub tswv yim yog qhov tsib Ritis coefficient (AST / ALT piv). Nyob rau hauv ib tug neeg noj qab nyob zoo, nws yog 1.3.
Cov kev soj ntsuam ntsig txog hom tshuaj muaj zog ntxiv rau cov kua paug (enzymes)
Ua kom muaj kev sib txawv ntawm ntau cov kab mob, qhov kev kuaj sim ntxiv tau kuaj xyuas qhov kev ntsuam xyuas thiab xyuas kom pom tag nrho cov siab hauv cov roj enzymes hauv cov ntshav. Ntawm ntau qhov chaw dystrophic ntawm lub siab, kab mob oncological, mob hnyav thiab kis kab mob, tus neeg mob Gldg cov ntsiab lus (hauv
Ib feem ntawm daim siab enzymes yog secreted rau hauv lub bile ducts. Lawv koom nrog hauv plab zom mov. Xws li ib qho enzyme yog alkaline phosphatase. Feem ntau cov ntsiab lus ntawm alkaline av hlau yuav tsum tsis pub tshaj 120 U / l. Tab sis yog hais tias metabolic metabolic cov txheej txheem raug ua txhaum, qhov kev lag luam no nce mus rau 400 U / l.
