Kev kuaj ntshav LDH (Lactic Dehydrogenase): nws yog dab tsi thiab qhov txiaj ntsig txhais tau li cas

Zoo Siab

• Qhov kev xeem yog dab tsi
• LDH siab txhais li cas?
• Dab tsi tuaj yeem ua qis LDH?

LDH, tseem hu ua lactic dehydrogenase lossis lactate dehydrogenase, yog ib qho enzyme muaj nyob rau hauv cov hlwb ua lub luag haujlwm rau cov metabolism hauv cov piam thaj hauv lub cev. Qhov enzyme no tuaj yeem pom nyob hauv ntau lub plab hnyuv siab raum thiab cov ntaub so ntswg thiab, yog li ntawd, nws qhov siab tsis yog qhov tshwj xeeb, thiab lwm qhov kev ntsuam xyuas tau pom zoo kom ncav cuag kev kuaj mob.

Thaum muaj qhov hloov pauv ntawm LDH, ntxiv rau lwm qhov kev sim, tus kws kho mob tuaj yeem qhia tias ntau npaum li cas ntawm LDH isoenzymes, qhov nce ntawm uas yuav qhia tau ntau yam tshwj xeeb hloov:

• LDH-1, uas yog nyob rau hauv lub siab, ntshav liab thiab raum;
• LDH-2, uas tuaj yeem pom hauv lub siab, rau tus neeg qis dua, thiab hauv leukocytes;
• LDH-3, uas yog nyob rau hauv lub ntsws;
• LDH-4, uas pom muaj nyob rau hauv cov txiaj ntsig thiab txiav;
• LDH-5, uas muaj nyob hauv daim siab thiab pob txha pob txha.

Cov txiaj ntsig qub ntawm lactate dehydrogenase tuaj yeem sib txawv raws li kev ntsuas, ua ib txwm xam los ntawm 120 thiab 246 IU / L hauv cov neeg laus.

Qhov kev xeem yog dab tsi

Kev kuaj ntshav LDH tuaj yeem txiav txim los ntawm tus kws kho mob raws li kev ntsuam xyuas niaj zaus, nrog rau lwm yam kev sim ntsuas. Txawm li cas los xij, qhov kev ntsuas no feem ntau tau hais txog kev tshawb nrhiav txog kev mob plawv, raug thov ua ke nrog Creatinophosphokinase (CK) thiab troponin, lossis ntawm hepatic alterations, tseem tau thov kom ntau dua ntawm TGO / AST (Oxalacetic Transaminase / Aspartate Aminotransferase), TGP / ALT (Glutamic Pyruvic Transaminase / Alanine Aminotransferase) thiab GGT (gamma glutamyl transferase). Nrhiav kom paub lwm yam kev ntsuam xyuas uas ntsuas lub siab.

Txhawm rau xeem qhov feem ntau tsis tas yuav yoo mov lossis lwm yam kev npaj, txawm li cas los xij qee lub chaw soj nstuam qhia tias nws yog qhov yuav tsum tau ua rau tus neeg yam tsawg kawg ntawm 4 teev yoo mov. Yog li, ua ntej ua qhov kev kuaj mob, nws yog ib qho tseem ceeb qhia rau lub chaw kuaj mob txog cov txheej txheem tsim nyog, ntxiv rau kev qhia txog kev siv tshuaj.

LDH siab txhais li cas?

Qhov nce hauv LDH feem ntau yog qhia txog kev puas tsuaj rau cov plab hnyuv siab raum lossis cov ntaub so ntswg. Qhov no yog vim tias vim qhov txiaj ntsig ntawm kev puas tsuaj ntawm tes, LDH muaj nyob hauv lub hlwb raug tso tawm thiab mus rau hauv cov hlab ntshav, thiab nws qhov kev tsom xam tau los ntawm kev ntsuas ntshav. Cov xwm txheej tseem ceeb uas qhov nce hauv LDH tuaj yeem pom yog:

• Megaloblastic anemia;
• Carcinoma;
• Septic poob siab;
• Cawv Liab;
• Hemolytic anemia;
• Mob ntsws mob;
• Mononucleosis;
• Kab mob siab;
• Obau lub cev tawv ncauj;
• Kab mob ntsws.

Qee qhov xwm txheej tuaj yeem nce LDH ntau ntau, tsis yog qhia tias muaj kab mob, tshwj xeeb yog tias lwm qhov kev thov kuaj kab mob tsis zoo. Qee qhov xwm txheej uas tuaj yeem hloov qib ntshav LDH hauv cov ntshav yog ua lub cev ua si nyhav, siv qee yam tshuaj noj thiab cev xeeb tub.

Dab tsi tuaj yeem ua qis LDH?

Kev txo qis ntawm cov kab mob lactic dehydrogenase hauv cov ntshav feem ntau tsis yog qhov ua rau muaj kev txhawj xeeb thiab tsis muaj feem xyuam rau kab mob thiab tsis yog lub laj thawj rau kev tshawb nrhiav. Qee qhov xwm txheej, qhov txo qis hauv LDH yuav cuam tshuam nrog qhov tshaj ntawm vitamin C, thiab kev hloov pauv ntawm tus neeg noj zaub mov kuj yuav pom zoo.
