Qhov sib txawv tseem ceeb ntawm cov ntshav thiab cov ntshav ntshav yog tias cov ntshav muaj cov ntshav txhaws thaum cov ntshav ntshav tsis muaj cov ntshav txhaws.
Ib qho kev xav tsis zoo ntawm tib neeg yog cov ntshav thiab ntshav yog tib yam. Lawv yog ob yam khoom sib txawv nrog cov kev daws teeb meem ua ntej thiab muaj cov khoom siv, uas ua rau lawv tshwj xeeb thiab xav tau rau ntau yam kev kho mob. Tus thawj precursor yog ntshav, thiab theem ntawm purification ntawm cov ntshav yog tus txiav txim ntawm plasma thiab serum. Thaum peb xav txog ntshav, nws yog tsim los ntawm cov qe ntshav liab, cov qe ntshav dawb, platelets, proteins, thiab cov khoom muaj dej. Plasma yog cov dej ntawm cov ntshav thaum cov ntshav yog cov ntshav yog ib feem uas tsis muaj cov ntshav txhaws. Ob yam khoom no tseem ceeb hauv cov txheej txheem kho mob thiab kuaj mob hauv tib neeg, thiab muaj ntau yam kev tshawb fawb txuas ntxiv ntawm qhov tshwj xeeb ntawm cov tshuaj no.
Plasma yog dab tsi?
Plasma yog cov dej hauv cov ntshav. Peb muaj peev xwm soj ntsuam plasma; Yog tias peb sawv ntsug ib kab ntawm cov ntshav li ib teev, peb tuaj yeem pom cov nag lossis daus ntawm cov qe ntshav liab thiab cov qe dawb nrog cov kua txiv hmab txiv ntoo uas muaj xim zoo nkauj. Cov kua no yog plasma. Plasma muaj cov fibrinogen, ib qho tseem ceeb hauv cov txheej txheem ntawm cov ntshav txhaws thiab lwm yam tseem ceeb ntawm cov ntshav txhaws. Yog li, ntawm qhov sawv ntsug no cov quav quav quav quav quav quav quav quav quav quav tshuaj quav cawv.
Daim duab 01: Plasma
Ntxiv mus, cov plasma no tuaj yeem raug spun, yog li cov ntaub ntawv protein uas hnyav dua yuav ua rau poob qis, tawm hauv cov ntshav purified zoo dua. Plasma yog xav tau rau kev kuaj mob thiab tshwj xeeb tshaj yog rau kev kho cov ntshav hauv cov tib neeg, uas yog hypovolemic, tsis muaj cov ntshav txhaws, thiab lwm yam. Cov ntshav ntshav tsawg dua yog muaj xws li cryo poor plasma (CPP), thiab cov tshuaj tshem tawm cov hlab ntshav yog siv rau hauv kev kho mob. ntawm hemophiliacs li cryo precipitate.
YSerum yog dab tsi?
Serum yog plasma yam tsis muaj qhov cuam tshuam, feem ntau yog fibrinogen. Yog li serum, ntawm kev sawv tsis khov. Feem ntau, kom tau txais cov ntshav, tag nrho cov kab mob hauv cov ntshav tau raug tshem tawm los ntawm kev nce qib centrifuging, lossis peb tuaj yeem tau txais cov ntshav kuaj, thiab tom qab tso cai rau nws txhaws, cov tshuaj supernatant raug coj mus.
Daim duab 02: Serum
Serum suav nrog tag nrho lwm cov electrolytes, cov proteins uas tsis siv rau hauv cov txheej txheem txhaws, tshuaj thiab co toxins. Tib neeg cov ntshav feem ntau yog siv rau lub hom phiaj ntawm kev kuaj mob. Lwm cov tsiaj seras yog siv los tiv thaiv venom, tshuaj tua kab mob, thiab tshuaj tiv thaiv.
Dab tsi zoo sib xws ntawm Plasma thiab Serum?
- Ob leeg ntshav thiab ntshav muaj nyob hauv cov ntshav.
- Lawv yog cov khoom tseem ceeb ntawm cov ntshav.
- Ob leeg muaj cov metabolites, electrolytes, proteins thiab cov tshuaj tiv thaiv.
- Cov txheej txheem ntawm centrifugation tuaj yeem cais ob leeg ntawm cov ntshav.
- Ob leeg yog kua.
- Lawv muaj dej ntau tshaj 90%.
Qhov txawv ntawm Plasma thiab Serum yog dab tsi?
Plasma thiab ntshav ntshav yog ob yam tseem ceeb ntawm cov ntshav thiab cov hlab ntsha. Ob leeg tuaj yeem muab rho tawm los ntawm centrifugation. Plasma yog cov dej ntws ntawm cov ntshav uas tsis muaj cov hlwb thaum cov ntshav ntshav yog cov ntshav tsis muaj cov ntshav txhaws. Qhov no yog qhov sib txawv tseem ceeb ntawm plasma thiab ntshav. Tsis tas li ntawd, cov ntshav plasma suav rau feem pua ntawm tag nrho cov ntim thaum cov ntshav tso nyiaj rau ib feem me me ntawm tag nrho cov ntshav ntim.
Cov duab hauv qab no nthuav tawm cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm cov ntshav thiab ntshav hauv daim ntawv tabular.
Summary – Plasma vs Serum
Ntshav yog ib qho tseem ceeb hauv lub cev uas yog ib qho tseem ceeb rau kev thauj mus los ntawm cov as-ham thiab oxygen mus rau txhua lub cell hauv peb lub cev thiab tshem tawm cov metabolism hauv cov khoom pov tseg los ntawm cov ntaub so ntswg ntawm peb lub cev. Plasma thiab ntshav ntshav yog ob yam ntawm cov ntshav. Cov dej ib feem ntawm cov ntshav yog cov ntshav plasma thaum cov ntshav ntshav yog cov ntshav tsis muaj cov ntshav txhaws. Txij li cov ntshav ntshav tsis muaj cov ntshav txhaws, nws tsis tuaj yeem txhaws, txawm li cas los xij, txij li cov ntshav ntshav muaj cov ntshav txhaws, nws tuaj yeem txhaws. Qhov no yog qhov txawv ntawm ntshav ntshav thiab ntshav.
