Tag nrho cov ntshav yog fractionated rau hauv cov khoom tshwj xeeb, raws li hauv qab no: PRBC, FFP, platelet concentrates, thiab cryoprecipitate; FFP tej zaum yuav raug faib ua feem ntxiv rau hauv ib tus neeg qhov tseem ceeb ib yam nkaus.
Yuav ua li cas tom qab cov ntshav faib?
Fractionation suav nrog hloov pauv cov xwm txheej ntawm cov ntshav plasma (piv txwv li, qhov kub thiab txias lossis acidity) kom cov proteins uas ib txwm yaj hauv cov kua dej hauv plasma ua insoluble, tsim cov pawg loj., hu ua precipitate. Cov protein insoluble tuaj yeem sau los ntawm centrifugation.
Cov khoom ntawm cov ntshav sib cais li cas?
Ib lub tshuab hu ua centrifuge tig koj cov ntshav kom cais koj cov qe ntshav liab, platelets thiab ntshav. Raws li cov ntshav sib cais, cov qog ntshav liab hnyav dua nkag mus rau hauv qab thiab muab rov qab rau koj.
Dab tsi yog 2 yam tseem ceeb tag nrho cov ntshav tom qab nws muab faib?
Cov ntshav yog fractionated rau hauv nws lub hauv paus Cheebtsam ntawm plasma, platelets thiab qe ntshav liab. Txhua yam khoom raug muab rov qab rau tus neeg mob thaum lub sijhawm phais raws li qhov xav tau nrog qhov zoo tshaj plaws uas cov platelets thiab ntshav tso tseg rau qhov kawg ntawm cov txheej txheem.
Cov ntshav puas tuaj yeem faib tau?
Tag nrho cov ntshav tuaj yeem faib ua plaub yam tseem ceeb: plasma, qe ntshav dawb, qe ntshav liab, thiab platelets. Cov Cheebtsam no tuaj yeem tawg mus ntxiv rau hauv cov feem me me. Albumin yog ib qho protein ua nyob rau hauvdaim siab uas ntws los ntawm lub cev hauv plasma, uas yog cov kua dej tsis muaj xim ntawm cov ntshav.

Puas yog cov khoom lag luam thiab cov khoom pov tseg tib yam?
A by-product can be useful and marketable or it can be xav pov tseg: piv txwv li, bran, uas yog ib tug byproduct ntawm lub milling ntawm nplej rau refined hmoov, yog Qee zaum composted lossis hlawv rau pov tseg, tab sis lwm qhov, nws tuaj yeem siv los ua cov khoom noj muaj txiaj ntsig hauv tib neeg cov zaub mov lossis tsiaj pub.
Puas yog cov neeg tsim khoom lossis cov neeg siv khoom?
Daim duab qhia txog lub luag haujlwm tseem ceeb uas microbes xws li algae, cyanobacteria thiab cov decomposers, ua si thawj cov tsim khoomthiab hauv kev caij tsheb kauj vab. Puas yog cov microbes tsim lossis cov neeg siv khoom? Tab sis ntau yam kab mob tsis yog neeg tsim khoom thiab ua tsis tau lawv tus kheej cov zaub mov.
Puas yog cov roj chlorine yog cov khoom lossis cov khoom sib xyaw?
Chlorine yog nyob rau hauv pawg 17 ntawm lub sij hawm lub sij hawm, tseem hu ua lub halogens, thiab tsis pom raws li lub caij nyob rau hauv cov xwm - tsuas yog ib tug compound. Feem ntau ntawm cov no yog ntsev, los yog sodium chloride, thiab cov poov tshuaj compounds sylvite (los yog potassium chloride) thiab carnallite (potassium magnesium chloride hexahydrate).
Cov khoom siv puas yog khoom vaj khoom tsev?
khoom yog a khoom vaj khoom tsev ruaj khov, lossis khoom tsis yog tam sim no. Qhov no txhais tau tias nws yuav tsis raug muag hauv lub xyoo tom ntej accounting thiab tsis tuaj yeem ua kua tau yooj yim. Txawm hais tias nws yog qhov zoo kom muaj cov khoom muaj nqis tam sim no uas muab koj lub lag luam npaj nkag mus rau cov nyiaj ntsuab, tau txais cov cuab tam mus sij hawm ntev kuj yog qhov zoo.
Puas yog cov nroj tsuag carnivorous yog cov tsim khoom lossis cov neeg siv khoom?
As producers, cov nroj tsuag tsim lub hauv paus ntawm yuav luag txhua cov khoom noj hauv ntiaj teb. Carnivorous nroj tsuag zoo li "tig rooj" thaum lawv ua raws li cov neeg siv khoom, gobbling kab, qav, thiab cov tsiaj me me. Puas yog Venus flytrap yog tus neeg siv khoom thiab tsim khoom?
