Kev Taw Qhia Txog Centrifugation thiab Nws Qhov Tseem Ceeb Hauv Kev Sib Cais Ntshav
Kev siv centrifugation yog ib txoj kev siv zog heev uas siv rau ntau yam kev tshawb fawb thiab kev kho mob los cais cov khoom sib xyaw ua ke. Ib qho ntawm nws cov kev siv tseem ceeb yog kev cais cov khoom ntshav, uas muaj feem cuam tshuam loj heev rau kev kuaj mob thiab kev kho mob ntawm ntau yam kab mob. Los ntawm kev siv lub zog centrifugal, cov txheej txheem no ua rau muaj kev cais cov khoom sib txawv ntawm lub cev thiab cov molecular uas muaj nyob hauv cov ntshav, ua rau muaj kev tshuaj xyuas thiab kev tshawb fawb ntxiv.
To taub Cov Cheebtsam ntawm Cov Ntshav thiab Lawv Lub Luag Haujlwm
Ntshav, feem ntau hu ua "tus dej ntawm txoj sia," yog ib qho kua dej sib xyaw ua ke uas muaj ntau yam khoom xyaw uas ua haujlwm tseem ceeb hauv lub cev. Cov khoom no tuaj yeem muab faib ua peb pawg tseem ceeb: cov qe ntshav liab (erythrocytes), cov qe ntshav dawb (leukocytes), thiab cov platelets (thrombocytes). Tsis tas li ntawd, plasma, qhov kua ntawm cov ntshav, muaj ntau yam protein, cov tshuaj hormones, electrolytes, thiab lwm yam molecules tseem ceeb.
Cov qe ntshav liab (RBCs) muaj lub luag haujlwm nqa cov pa oxygen mus rau cov nqaij ntawm lub cev thiab tshem tawm cov pa roj carbon dioxide. Cov qe ntshav dawb (WBCs) ua lub luag haujlwm tseem ceeb hauv lub cev tiv thaiv kab mob, tiv thaiv lub cev tiv thaiv kab mob thiab cov neeg txawv teb chaws nkag los. Ntawm qhov tod tes, cov platelets yog qhov tseem ceeb rau kev txhaws ntshav, tiv thaiv kev los ntshav ntau dhau. Kev nkag siab txog cov haujlwm thiab cov khoom ntawm cov khoom no yog qhov tseem ceeb rau kev kuaj mob thiab kev kho mob.
Cov Txheej Txheem ntawm Centrifugation: Ib Kauj Ruam Piav Qhia
Kev siv centrifugation yog kev sib cais cov khoom sib txawv ntawm cov khoom sib xyaw raws li lawv qhov loj me, qhov ceev, thiab cov duab. Hauv cov ntsiab lus ntawm kev sib cais cov khoom ntshav, cov txheej txheem pib nrog kev sau cov qauv ntshav los ntawm cov tib neeg. Cov qauv no feem ntau yog anticoagulated kom tiv thaiv kev txhaws.
Kauj Ruam 1: Kev Npaj thiab Cov Raj Centrifugation
Cov ntshav kuaj raug sau rau hauv cov raj tshwj xeeb hu ua cov raj centrifuge, uas tau tsim los kom tiv taus lub zog loj ntawm lub ntiajteb txawj nqus thaum lub sijhawm centrifugation. Cov raj tau muab sau ua ntawv kom zoo kom paub tseeb tias cov khoom sib cais raug txheeb xyuas.
Kauj Ruam 2: Teeb tsa Centrifuge
Lub centrifuge no teeb tsa nrog lub rotor thiab cov tuav raj uas tsim nyog, xav txog hom thiab qhov ntim ntawm cov ntshav kuaj. Lub centrifuge ua haujlwm los ntawm kev tig cov qauv ntawm qhov ceev ceev, yog li tsim lub zog centrifugal.
Kauj Ruam 3: Cov Cheebtsam Ntshav Uas Muaj Txheej
Cov ntshav kuaj raug muab tso rau hauv cov raj centrifuge, thiab thaum tig, lub zog siv ua rau cov ntshav sib cais ua ntau txheej. Cov khoom ntom dua yuav nyob hauv qab ntawm lub raj, thaum cov khoom ntom tsawg dua yuav nyob rau sab saum toj.
Kauj Ruam 4: Kev Sau Cov Cheebtsam
Tom qab centrifugation, lub raj raug tshem tawm ntawm lub centrifuge kom zoo zoo, kom ntseeg tau tias tsis muaj kev sib xyaw lossis kev sib tov. Tom qab ntawd cov khaubncaws sab nraud povtseg raug cais kom zoo zoo siv cov pipettes, cov khoom siv nqus, lossis cov cuab yeej tshwj xeeb, nyob ntawm seb cov khoom sib cais xav tau.
Cov Kev Siv Centrifugation Hauv Kev Kho Mob thiab Kev Tshawb Fawb
Kev sib cais cov khoom ntshav los ntawm kev centrifugation muaj ntau yam kev siv hauv kev kho mob thiab kev tshawb fawb. Hauv kev kuaj mob, nws ua lub luag haujlwm tseem ceeb hauv kev txheeb xyuas thiab saib xyuas cov kab mob xws li ntshav tsis txaus, kev kis kab mob, leukemia, thiab cov kab mob autoimmune. Los ntawm kev cais cov khoom tshwj xeeb, cov kws kho mob tuaj yeem ua kev tshuaj xyuas ntxiv thiab kuaj mob, pab txhawb kev kuaj mob thiab kev kho mob kom raug.
Hauv kev tshawb fawb, kev siv centrifugation dav dav los tshawb nrhiav cov kab mob ntsig txog ntshav, kawm txog cov pej xeem tshwj xeeb hauv cov hlwb, thiab tshuaj xyuas ntau yam cim protein lossis cov khoom siv caj ces uas cuam tshuam nrog ntau yam mob. Los ntawm kev sib cais cov khoom ntshav, cov kws tshawb fawb tuaj yeem tau txais kev nkag siab zoo txog cov txheej txheem kab mob, tsim cov kev kho mob tshiab, thiab ntsuas qhov ua tau zoo ntawm kev kho mob.
Cov Teeb Meem thiab Kev Txhim Kho Yav Tom Ntej hauv Kev Sib Cais Cov Cheebtsam Ntshav
Txawm hais tias kev siv centrifugation tau ua pov thawj tias yog ib txoj kev tseem ceeb rau kev sib cais cov khoom ntshav, nws muaj qee yam teeb meem. Ib qho teeb meem loj yog qhov ua tau tias yuav muaj kev sib kis lossis kev sib cais tsis tiav vim muaj qee cov khoom sib tshooj. Kev kov yeej qhov teeb meem no yuav tsum tau ua tib zoo kho cov kev ntsuas centrifugation, suav nrog qhov ceev, lub sijhawm, thiab qhov kub.
Tsis tas li ntawd xwb, cov txheej txheem tam sim no rau kev sib cais cov ntshav feem ntau xav tau cov khoom siv centrifuge loj thiab kim, ua rau lawv tsis yooj yim siv tau rau hauv cov chaw uas muaj peev txheej tsawg. Txawm li cas los xij, kev tshawb fawb tseem tab tom tsom mus rau kev tsim cov thev naus laus zis centrifugation pheej yig uas yooj yim nqa tau los ua kom kev sib cais cov ntshav yooj yim dua thoob ntiaj teb.
Saib mus tom ntej, kev nce qib xws li cov khoom siv microfluidic, cov thev naus laus zis hauv chav kuaj, thiab cov txheej txheem sib cais tshiab yuav hloov pauv qhov kev sib cais cov khoom ntshav. Cov thev naus laus zis tshiab no tuaj yeem txhim kho kev ua haujlwm zoo, kev ceev, thiab kev ntseeg siab ntawm kev sib cais cov khoom ntshav, qhib txoj hauv kev rau kev kuaj mob zoo dua, kev kho mob rau tus kheej, thiab kev kho mob uas tsom mus rau ntau yam.
Xaus lus
Xaus lus, centrifugation ua lub luag haujlwm tseem ceeb hauv kev sib cais cov khoom ntshav, pab txhawb kev kuaj mob, kev tshawb fawb, thiab kev txhim kho kev kho mob. Los ntawm kev nkag siab txog cov ntsiab cai tom qab txoj kev no thiab ua tib zoo kho cov txheej txheem, cov kws kho mob thiab cov kws tshawb fawb tuaj yeem cais thiab tshuaj xyuas cov khoom ntawm cov ntshav, yog li tau txais kev nkag siab zoo rau ntau yam kab mob thiab txhim kho kev saib xyuas tus neeg mob.
