Qhov Tseem Ceeb Qhov txawv - A vs B Antigens
Ntshav yog ib qho tseem ceeb ntawm kev thauj mus los hauv peb lub cev. Nws muaj cov hlwb sib txawv xws li cov qe ntshav liab thiab cov qe ntshav dawb. Cov qe ntshav liab suav txog 45% ntawm tag nrho cov ntim thaum cov qe ntshav dawb tsuas yog 1%. Tus so ntawm 55% muaj ntshav plasma. Cov pob txha pob txha ntawm cov pob txha tsim cov qe ntshav liab. Cov qe ntshav dawb yog lub luag haujlwm rau peb kev tiv thaiv. Cov qe ntshav liab yog qhov tseem ceeb hauv cov pa oxygen thiab kev thauj mus los rau cov ntaub so ntswg. Muaj plaub hom ntshav tseem ceeb hu ua A, B, AB thiab O. Lawv muaj npe raws li qhov muaj lossis tsis muaj cov tshuaj tiv thaiv tshwj xeeb ntawm cov ntshav liab. Thiab cov antigens no hu ua antigen A thiab antigen B. Raws li lawv lub xub ntiag (+) lossis tsis muaj (-), hom ntshav tau muab faib ua A+, A– , B+, B–, AB+, AB– , O+, thiab O– Qhov sib txawv tseem ceeb ntawm A thiab B antigens yog tias antigen A tuaj yeem pom hauv tib neeg nkaus xwb. leej twg muaj ntshav pawg A thiab ntshav AB thaum antigen B tuaj yeem pom tsuas yog hauv cov neeg uas muaj ntshav pawg B thiab ntshav AB.
Antigens yog dab tsi?
ntshav pawg antigens yog glycoproteins uas muaj nyob rau ntawm cov qe ntshav liab. Lub antigen A yog txhais tau tias yog cov ntshav antigen uas nyob rau hauv cov ntshav liab ntawm cov neeg uas muaj ntshav pawg A thiab AB. Cov tshuaj tiv thaiv no tsis tuaj yeem pom hauv cov neeg uas muaj ntshav "B" thiab "O."
Daim duab 01: Kev Ntsuas Kev Sib Raug Zoo
Hauv kev tshawb fawb txog ntshav, antigen A tseem ceeb heev. Raws li lub koom haum thoob ntiaj teb kev hloov ntshav (ISBT), ABO cov pab pawg ntshav thiab RhD cov ntshav pab pawg tseem ceeb dua thaum nws los ntshav. Yog li, tus neeg uas koom nrog pawg ntshav A muaj cov tshuaj tiv thaiv "A" hauv cov qe ntshav liab thiab IgM antibody "B" hauv cov ntshav. Yog li, tus neeg uas muaj ntshav pawg A tuaj yeem txais cov ntshav los ntawm cov neeg uas muaj ntshav "A" lossis "O." Ntawm qhov tod tes, cov tib neeg uas muaj ntshav ntshav A tuaj yeem pub ntshav rau cov neeg uas muaj ntshav "A" lossis "AB." Txawm li cas los xij, tus neeg mob Rh-negative uas twb rhiab heev tuaj yeem tsim cov tshuaj tiv thaiv kab mob tseem ceeb thaum tau txais cov ntshav Rh-zoo rau zaum ob. Ib qho piv txwv zoo ntawm qhov xwm txheej no yog kab mob hemolytic ntawm tus menyuam yug tshiab (HDN).
B Antigens yog dab tsi?
Cov tshuaj tiv thaiv B yog txhais tau tias yog glycoprotein uas nyob rau ntawm cov ntshav liab ntawm cov neeg uas muaj ntshav pawg B thiab cov ntshav AB. Cov tib neeg uas muaj hom ntshav "A" thiab "O" tsis muaj cov tshuaj tiv thaiv no ntawm lawv cov qe ntshav liab. Cov tshuaj tiv thaiv no tseem ceeb heev hauv kev tshawb fawb txog kev hloov ntshav.
Daim duab 02: Hom Ntshav thiab Antigens
Ib tus neeg uas muaj cov ntshav B muaj "B" antigen ntawm cov qe ntshav liab thiab IgM antibody "A" hauv cov ntshav. Yog li hauv kev tshawb fawb txog kev hloov ntshav, tus neeg uas muaj ntshav pawg B tuaj yeem tau txais cov ntshav los ntawm cov neeg uas muaj ntshav "B" lossis "O." Cov tib neeg ntawm cov ntshav B tuaj yeem pub ntshav rau cov neeg uas muaj ntshav hom “B” lossis “AB.”
Dab tsi yog qhov zoo sib xws ntawm A thiab B Antigens?
- Ob leeg yog glycoproteins.
- Ob leeg tam sim no nyob rau hauv cov ntshav liab ntawm tib neeg.
- Ob leeg tuaj yeem khi rau lawv cov tshuaj tiv thaiv kab mob ("A" antibody thiab "B" antibody).
- Ob leeg tseem ceeb heev hauv kev tshawb fawb txog ntshav.
- Ob leeg muaj nyob hauv pawg ntshav "AB."

Summary – A vs B Antigens
Cov kab mob tseem ceeb tshaj plaws hauv kev hloov ntshav yog ABO system thiab RhD system. Ntau cov alleles tswj cov kab mob ABO cov ntshav, thiab nws nyob ntawm ob lub antigens (antigen A thiab B) ntawm cov ntshav liab. Tus neeg uas muaj antigen A ntawm cov ntshav liab saum npoo av muaj "B" IgM antibody hauv cov ntshav. Lawv nyob rau hom A hom ntshav. Tus neeg uas muaj antigen B nyob rau hauv cov ntshav liab nto muaj "A" IgM antibody nyob rau hauv cov ntshav. Lawv nyob rau hauv hom B hom ntshav. Cov tib neeg uas muaj hom ntshav AB muaj ob qho tib si antigens A thiab B hauv lawv cov qe ntshav liab. Tab sis lawv tsis muaj cov tshuaj tiv thaiv kab mob hauv lawv cov ntshav. Cov ntshav hom O cov tib neeg tsis muaj A antigen lossis B antigen ntawm lawv cov qe ntshav liab. Tab sis lawv cov ntshav ntshav muaj ob qho IgM cov tshuaj tiv thaiv "A" thiab "B." Qhov no yog qhov txawv ntawm A thiab B antigens.
