ABO antigens thiab cov tshuaj tiv thaiv kab mob
| Lub npe ntawm Ntshav Pawg | Antigens tam sim no cov liab ntawm tes | ABO tshuaj tiv thaiv nthuav qhia hauv cov ntshav |
|---|---|---|
| Hom O | tsis muaj | anti-A thiab anti - B |
| Hom A | Ib antigen | tiv thaiv - B |
| Hom B . | B antigen | tiv thaiv -A |
| Hom AB | A thiab B antigens | tsis muaj |
Hauv qhov no, pawg ntshav twg muaj cov tshuaj tiv thaiv kab mob A thiab B nyob hauv ntshav?
AB . Cov ' AB ' hom ntshav , tseem hu ua "universal receiver" hom ntshav , muaj ob leeg cov A thiab B antigens ntawm liab ntshav cell, tab sis tsis muaj A lossis B tiv thaiv hauv ntshav . Raws li qhov tshwm sim, cov tib neeg nrog ' AB ' hom ntshav tej zaum yuav tau txais kev hloov ntshav ntawm txhua yam ntshav.
Qhov thib ob, cov ntshav A puas muaj cov tshuaj tiv thaiv kab mob B? Cov neeg nrog muaj ntshav A antigen A nyob saum npoo ntawm lawv RBCs, thaum tib neeg nrog muaj ntshav hom B cov B antigen. Cov tshuaj tiv thaiv kab mob uas tawm tsam tiv thaiv antigen A hu ua anti-A, thiab pom hauv ntshav ntawm cov neeg uas ua tsis muaj antigen A ntawm lawv tus kheej RBCs - uas yog, cov neeg nrog yam O sau ntshav hom B.
Thiaj li, hom ntshav twg nqa cov tshuaj tiv thaiv kab mob hauv plasma?
Ntshav pab pawg B muaj B antigens nrog anti-A antibodies hauv cov ntshav. Cov ntshav pawg A muaj A antigens ntawm cov qe ntshav liab nrog rau B cov tshuaj tiv thaiv kab mob hauv ntshav. Qhov sib xyaw ua ke ntawm antigens thiab tshuaj tiv thaiv kab mob txiav txim seb hom ntshav twg koj tuaj yeem tau txais kev nyab xeeb rau lub hom phiaj kho mob.
Cov tshuaj tiv thaiv kab mob A thiab anti B tuaj qhov twg?
Antibodies tsim tawm tsam ABO ntshav pawg antigens Ib txwm tshwm sim. Tiv thaiv -A tau pom nyob hauv cov ntshav ntawm cov neeg uas muaj ntshav pawg O thiab B . Tiv thaiv - B muaj nyob hauv cov ntshav ntawm cov neeg uas muaj ntshav pawg O thiab A.

Qhov twg ntawm cov tshuaj tiv thaiv hauv qab no yog siv rau kev txhaj tshuaj tiv thaiv kab mob?
Passive Immunization DISEASE NAME OF MATERIAL Cytomegalovirus Cytomegalovirus immun globulin, txhaj tshuaj tiv thaiv kab mob Diphtheria Diphtheria antitoxin, equine Rabies Rabies tiv thaiv globulin, tib neeg Measles Immune globulin, tib neeg
Cov ntsiav tshuaj daim ntawv twg muaj cov txheej tshwj xeeb uas tiv thaiv lub plab acid thiab ua rau cov tshuaj yaj hauv cov hnyuv?
Cov txheej txheej enteric yog cov txheej txheem polymer siv rau ntawm cov tshuaj hauv qhov ncauj uas tiv thaiv nws txoj kev tawg lossis tsis tawg hauv ib puag ncig lub plab
Hom cell twg hauv lub cev tiv thaiv kab mob tsim cov tshuaj tiv thaiv?
Lymphocytes yog ib hom tseem ceeb ntawm lub cev tiv thaiv kab mob. Lymphocytes feem ntau muab faib ua B thiab T hlwb. B lymphocytes tsim cov tshuaj tiv thaiv - cov protein (gamma globulins) uas lees paub cov tshuaj txawv teb chaws (antigen) thiab muab lawv tus kheej rau lawv
Dab tsi yog cov tshuaj tiv thaiv thiab lawv cuam tshuam nrog cov tshuaj tiv thaiv li cas?
Cov tshuaj tiv thaiv kab mob (immunoglobins) yog cov protein zoo li Y tsim los ntawm B hlwb ntawm lub cev tiv thaiv kab mob hauv kev teb rau kis rau antigens. Txhua cov tshuaj tiv thaiv muaj ib qho paratope uas paub txog ib qho epitope ntawm ib qho antigen, ua zoo li lub xauv thiab qhov tseem ceeb binding mechanism
Cov tshuaj tiv thaiv ua haujlwm li cas lawv ua haujlwm tiv thaiv kab mob thiab kab mob?
Cov tshuaj tiv thaiv ua haujlwm los ntawm kev cob qhia lub cev tiv thaiv kab mob kom paub thiab tawm tsam cov kab mob, xws li kab mob lossis kab mob. Txhawm rau ua qhov no, qee cov molecules los ntawm cov kab mob yuav tsum tau nkag rau hauv lub cev kom ua rau muaj kev tiv thaiv kab mob. Cov molecules no hu ua antigens, thiab lawv muaj nyob rau tag nrho cov kab mob thiab cov kab mob
