Qhov kev xeem los txiav txim siab koj li ntshav pab pawg hu ua ABO kev ntaus ntawv . Koj ntshav qauv yog sib xyaw nrog cov tshuaj tiv thaiv kab mob yam A thiab B ntshav . Tom qab ntawd, cov qauv raug kuaj xyuas seb puas muaj lossis tsis yog ntshav cell ua ke. Yog ntshav cell ua ke, nws txhais tau tias ntshav reacted nrog ib qho ntawm cov tshuaj tiv thaiv kab mob.
Tsis tas li ntawd, cov tshuaj tiv thaiv kab mob siv rau kev ntaus ntshav li cas?
Cov tshuaj tiv thaiv kuj yog siv los pab peb lub cev nrhiav thiab rhuav tshem "txawv teb chaws" cov hlwb xws li qog nqaij hlav. Vim tshuaj tiv thaiv khi nruj nreem rau ib leeg xwb yam ntawm cov qauv ntawm cov cell (antigens), lawv kuj tseem tuaj yeem siv tau los txheeb xyuas ntau hom ntshav hlwb. Qhov no hu ua ABO ntshav typing lawv.
Ib tug kuj yuav nug, kuaj ntshav puas qhia hom ntshav? The ABO xeem qhia tias tib neeg muaj ib ntawm plaub hom ntshav : A, B, AB, or O. Yog koj lub liab ntshav cell muaj: Tus A antigen, koj muaj yam A ntshav . Cov kua dej ntawm koj ntshav (ntshav) muaj cov tshuaj tiv thaiv uas tawm tsam yam B ntshav.
Kuj paub, vim li cas kev sib sau tshwm sim hauv cov ntshav?
Agglutination yog tus txheej txheem ntawd tshwm sim yog tias antigen tau sib xyaw nrog nws cov tshuaj tiv thaiv kab mob hu ua isoagglutinin. Cov clumping ntawm cov cell xws li cov kab mob lossis liab ntshav cell nyob rau hauv lub xub ntiag ntawm ib tug antibody los yog ntxiv. Cov tshuaj tiv thaiv kab mob los yog lwm cov qauv sib txuas ua ke ntau qhov sib txuas thiab koom nrog lawv, tsim kom muaj qhov nyuaj loj.
Koj ntaus ntshav li cas?
Cov txheej txheem ntshav:
- Sib tov! Ua ntej sib xyaw cov neeg mob cov ntshav nrog peb qhov sib txawv reagents nrog rau ntawm peb cov tshuaj tiv thaiv kab mob sib txawv, A, B lossis Rh antibodies!
- Nrhiav agglutination! Tom qab ntawd koj saib seb muaj dab tsi tshwm sim.
- Txheeb tawm ABO pawg ntshav!
- Tshawb nrhiav cov pab pawg Rh!
- Txheeb xyuas hom ntshav!

Nws txhais li cas yog tias koj ua tsis tiav koj qhov kev kuaj ntshav qab zib thaum cev xeeb tub?
Mob ntshav qab zib thaum cev xeeb tub yog mob ntshav qab zib siab uas 2-5 feem pua ntawm cov poj niam cev xeeb tub tsim thaum cev xeeb tub. Vim tias qhov xwm txheej no tsis tshua pom muaj cov tsos mob pom, ua qhov ntsuas ntshav qab zib yog tib txoj hauv kev kom paub seb tus neeg mob puas muaj nws
Cov kev kuaj ntshav lab tau ua tiav dab tsi rau ntshav siab?
Cov kev ntsuas no suav nrog cov hauv qab no: Ntshav ntshav, suav nrog ntsuas electrolytes, ntshav urea nitrogen, thiab qib creatinine (txhawm rau ntsuas kev koom tes ntawm lub raum) Lipid profile rau qib ntawm ntau hom roj (cholesterol). Kev ntsuam xyuas tshwj xeeb rau cov tshuaj hormones ntawm cov qog adrenal lossis cov thyroid
Cov kab mob kis tau zoo li cas hauv chav kuaj?
Kab mob tsiaj thiab cog tau cog rau hauv kab lis kev cai ntawm tes. Cov hlwb tau khaws cia ciaj sia nyob rau hauv kev ncua ntawm kev loj hlob yam hauv Petri tais. Ib txheej nyias nyias ntawm cov cell, lossis monolayer, tom qab ntawd kis nrog cov kab mob, thiab rov ua dua. Fertilized qe thiab cov tsiaj muaj sia kuj tuaj yeem siv los cog cov kab mob
Vim li cas thiaj xaiv cov ntshav ntau dua cov ntshav hauv kev kuaj tshuaj lom neeg?
Qhov no yog vim peb qhov kev siv tshuaj lom neeg siv sijhawm sib txawv raws cov ntshav tsis yog ntshav. Piv txwv li, LDH, poov tshuaj thiab phosphate yog siab dua nyob rau hauv cov ntshav ntau dua li cov ntshav ntshav, vim yog tso tawm cov ntsiab lus ntawm cov cell thaum lub sij hawm txhaws. Cov protein thiab globulins siab dua hauv ntshav dua li cov ntshav, vim tias cov ntshav muaj fibrinogen
Cov chav hauv plawv twg hu ua chav tso kua mis?
Cov chav sab saud yog hu ua atria thiab ua raws li cov chav txais. Cov chav qis yog hu ua ventricles; cov no yog cov twj tso kua mis. Muaj plaub lub li qub nyob rau hauv lub plawv, uas pab tswj cov ntshav khiav. Ntshav qis hauv cov pa oxygen rov qab los ntawm lub cev thiab nkag mus rau sab xis atrium
