Kev Taw Qhia Txog Kev Sib Cais Ntshav thiab Kev Centrifugation
Ntshav yog ib feem tseem ceeb ntawm tib neeg lub cev, ua ntau yam haujlwm xws li kev thauj cov pa oxygen, kev tshem tawm cov khib nyiab, thiab kev tiv thaiv kab mob. Nws muaj ntau yam khoom sib txawv ntawm tes thiab tes, suav nrog cov qe ntshav liab thiab cov qe ntshav dawb, cov ntshav platelets, cov ntshav, cov tshuaj hormones, thiab cov enzymes. Yuav kom kawm tau cov khoom no ib leeg rau kev kuaj mob lossis kev tshawb fawb, nws yog ib qho tsim nyog yuav tsum cais lawv. Qhov no yog qhov uas centrifugation los ua si.
Lub Ntsiab Cai Ua Haujlwm ntawm Centrifuges hauv Kev Sib Cais Ntshav
Kev centrifugation yog ib qho txheej txheem uas siv cov ntsiab cai ntawm lub zog centrifugal los cais cov khoom sib xyaw raws li lawv qhov ceev thiab qhov loj. Lub centrifuge yog ib lub cuab yeej tshwj xeeb uas tig ntawm qhov ceev ceev, tsim ib lub teb centrifugal. Thaum cov ntshav raug lub zog no, cov khoom ntom ntom txav deb ntawm qhov chaw ntawm kev tig, thaum cov khoom ntom ntom tsawg dua sib sau ua ke ze rau qhov chaw. Qhov kev sib cais no tso cai rau kev cais cov khoom tshwj xeeb uas xav tau.
Hom Centrifuges Siv Rau Kev Sib Cais Ntshav
Muaj ntau hom centrifuges siv rau kev sib cais ntshav, suav nrog cov centrifuges saum rooj, cov centrifuges qauv hauv pem teb, ultracentrifuges, thiab microcentrifuges. Cov centrifuges saum rooj feem ntau siv hauv cov chaw kuaj mob vim lawv qhov ua tau ntau yam thiab me dua. Cov centrifuges qauv hauv pem teb loj dua thiab muaj zog dua, feem ntau siv hauv cov txhab ntshav lossis cov chaw tshawb fawb. Ultracentrifuges muaj peev xwm ua tiav qhov ceev heev thiab tuaj yeem sib cais cov khoom me me nrog qhov tseeb zoo. Microcentrifuges yog compact thiab tsim rau cov ntawv thov me dua, feem ntau siv hauv kev tshawb fawb txog noob caj noob ces lossis cov chaw kuaj mob microbiology.
Cov Txheej Txheem Cais Cov Cheebtsam Ntshav Siv Centrifugation
Yuav kom cais cov ntshav sib xyaw ua ke siv lub tshuab centrifuge, thawj kauj ruam yog sau cov ntshav rau hauv lub thawv uas tsim nyog, xws li lub raj kuaj lossis lub raj sau ntshav tshwj xeeb. Tom qab ntawd cov ntshav no raug muab tso rau hauv lub rotor centrifuge, uas tau sib npaug kom tsis txhob muaj kev cuam tshuam thaum lub sijhawm ua haujlwm. Tom qab kaw lub hau centrifuge, lub tshuab raug teeb tsa rau qhov ceev thiab lub sijhawm xav tau. Nws pib tig, tsim lub zog centrifugal uas ua rau cov ntshav.
Thaum lub sijhawm centrifugation, cov khoom sib xyaw ntawm cov ntshav uas tuab dua, xws li cov qe ntshav liab, yuav mus rau hauv qab ntawm lub raj vim lawv qhov ntom dua. Qhov no hu ua cov av qeeg lossis cov pellet. Saum toj ntawm cov av qeeg, ib txheej ntawm cov qe ntshav dawb thiab cov platelets kuj tseem yuav tsim tau. Cov kua dej seem, hu ua plasma, tsis tuab dua thiab sib sau ua ke rau saum. Lub sijhawm ntawm centrifugation sib txawv nyob ntawm qib kev sib cais uas xav tau.
Thaum lub centrifuge nres lawm, cov khoom sib cais tuaj yeem raug khaws cia kom zoo. Piv txwv li, lub pipette tuaj yeem siv los rho cov plasma lossis txheej sab saud ntawm cov cell. Cov khoom sib sau ua ke tuaj yeem siv rau kev kuaj ntxiv, kev tshuaj xyuas, lossis kev khaws cia. Los ntawm kev cais cov khoom ntshav siv centrifugation, cov kws tshawb fawb thiab cov kws kho mob tuaj yeem tau txais kev nkag siab zoo txog ntau yam kab mob, saib xyuas kev noj qab haus huv ntawm tus neeg mob, thiab ua kev tshawb fawb txog kev kho mob tshiab.
Cov Ntawv Thov thiab Cov Zoo ntawm Centrifugation hauv Kev Sib Cais Ntshav
Kev siv lub tshuab centrifugation ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv kho mob. Hauv cov chaw kuaj mob, nws siv rau kev kuaj ntshav niaj hnub, uas tso cai rau kev ntsuas cov yam xws li hematocrit, uas txiav txim siab feem pua ntawm cov qe ntshav liab hauv cov qauv. Ntxiv mus, nws pab hauv kev kuaj mob thiab saib xyuas ntau yam kab mob ntshav thiab kev kis kab mob. Kev siv lub tshuab centrifugation kuj tseem siv rau hauv cov txhab ntshav los cais cov ntshav tag nrho rau hauv nws cov khoom, xws li cov qe ntshav liab, plasma, thiab platelets, uas tso cai rau kev hloov ntshav kom muaj kev nyab xeeb thiab ua haujlwm tau zoo.
Tsis tas li ntawm qhov chaw kho mob, kev siv centrifugation kuj siv rau hauv cov chaw soj ntsuam los tshawb nrhiav cov kab mob ntsig txog ntshav thiab tshawb nrhiav cov kev kho mob uas muaj peev xwm kho tau. Nws ua rau muaj kev cais cov qe ntshav tshwj xeeb, ua kom yooj yim rau kev tshawb nrhiav txog lawv cov qauv, kev ua haujlwm, thiab kev teb rau cov tshuaj stimuli. Tsis tas li ntawd, kev siv centrifugation kuj siv rau hauv kev lag luam tshuaj los ntxuav thiab cais cov khoom uas tau los ntawm cov ntshav, suav nrog cov protein plasma thiab cov khoom ua rau cov ntshav khov, uas yog qhov tseem ceeb rau kev tsim ntau yam tshuaj thiab kev kho mob.
Xaus lus, centrifugation yog ib txoj kev siv zog heev los cais cov ntshav raws li lawv qhov ceev thiab qhov loj. Los ntawm kev siv cov ntsiab cai ntawm lub zog centrifugal, centrifuges tuaj yeem cais cov qe ntshav liab thiab dawb, platelets, thiab plasma, ua rau muaj kev kuaj mob thiab kev tshawb fawb tseem ceeb. Txawm hais tias nws yog kev kuaj mob niaj hnub, kev hloov ntshav, lossis kev tsim cov kev kho mob yav tom ntej, centrifugation txuas ntxiv hloov pauv qhov kev sib cais ntshav, ua rau peb nkag siab zoo dua thiab txhim kho kev saib xyuas tus neeg mob.
