Xyoo 1900 Karl Landsteiner nrhiav tau tias lub ntshav ntawm ob tus neeg nyob rau hauv kev sib cuag agglutinates, thiab hauv 1901 nws pom tias qhov cuam tshuam no yog vim kev sib cuag ntawm ntshav nrog ntshav ntshav qab zib. Yog li ntawd, nws ua tiav hauv kev txheeb xyuas peb ntshav pawg A, B thiab O, uas nws sau npe C, ntawm tib neeg ntshav.
Cia li xav txog qhov no, Karl Landsteiner nrhiav tau dab tsi thiab nws cuam tshuam dab tsi rau tib neeg?
Karl Landsteiner pom tib neeg cov ntshav hauv xyoo 1900 thiab tau tsim lub hauv paus rau kev kho mob niaj hnub ntawm kev hloov ntshav. ABO pawg ntshav muaj lub luag haujlwm hauv physiology dhau lawv qhov tseem ceeb rau kev tso ntshav.
Tsis tas li ntawd, leej twg ua Karl Landsteiner ua haujlwm nrog? Peb caug xyoo tom qab, nws tau txais khoom plig Nobel hauv Physiology lossis Tshuaj rau nws pom ntawm ABO cov pab pawg ntshav. Ua haujlwm nrog Erwin Popper, uas Landsteiner Ua pov thawj tias tus mob polio yog tus kab mob kis tau los ntawm tus kab mob thiab, nrog Viktor Mucha, nws tau pom tias kev siv tshuaj tua kab mob tsaus nti tuaj yeem siv los kuaj mob syphilis.
Cov lus nug tseem yog, hom ntshav nrhiav tau li cas?
Taw qhia. Nws tsis yog txog xyoo 1900, thaum Karl Landsteiner ntawm University of Vienna, nrhiav pom vim qee ntshav kev hloov ntshav tau ua tiav thaum lwm tus tuaj yeem ua rau tuag taus. Landsteiner nrhiav pom the ABO ntshav pab pawg los ntawm kev sib xyaw cov qe liab thiab cov ntshav ntawm txhua tus ntawm nws cov neeg ua haujlwm.
Leej twg pom ntshav sau?
Cov hom ntshav ABO tau tshawb pom los ntawm Karl Landsteiner xyoo 1901, uas nws tau txais khoom plig Nobel hauv Physiology lossis Tshuaj hauv xyoo 1930.

Puas yog tag nrho cov hlab ntsha nqa cov ntshav oxygenated thiab cov leeg nqa cov ntshav deoxygenated?
Cov hlab ntsha ua ib feem ntawm lub circulatory system. Cov hlab ntsha nqa cov ntshav oxygenated tawm ntawm lub plawv mus rau cov ntaub so ntswg, tshwj tsis yog cov hlab ntshav hauv lub ntsws, uas nqa ntshav mus rau lub ntsws rau cov pa oxygen (feem ntau cov leeg ntshav nqa cov ntshav deoxygenated mus rau lub plawv tab sis cov leeg hauv ntsws nqa cov ntshav oxygenated ib yam)
Cov ntshav twg yuav pom cov xim yog tias nws muaj cov pa oxygen siab?
Hauv lub ntsws, muaj cov pa oxygen ntau heev, uas txuas nrog cov hemoglobin. Yog li cov ntshav tawm hauv lub ntsws los ntawm cov hlab ntsws - cov leeg nkaus xwb uas nqa cov pa oxygen ntau dua li cov ntshav deoxygenated -rov qab mus rau lub plawv siab nrog cov pa oxygen thiab ci liab xim
Cov kua ntshav ntshav yog dab tsi tom qab cov qe ntshav thiab cov ntshav khov tau raug tshem tawm?
Cov ntshav yog cov kua ntshav tom qab cov qe ntshav thiab cov protein sib xyaw tau raug tshem tawm. cov pa roj ntshav suav nrog oxygen, carbon dioxide, thiab nitrogen
Vim li cas cov protein pom hauv cov ntshav plasma?
Ntshav proteins, tseem hu ua plasma proteins, yog cov proteins uas muaj nyob rau hauv cov ntshav plasma. Lawv ua haujlwm ntau yam sib txawv, suav nrog thauj lipids, cov tshuaj hormones, cov vitamins thiab cov zaub mov hauv kev ua haujlwm thiab ua haujlwm ntawm lub cev tiv thaiv kab mob. Tag nrho cov ntshav protein sib xyaw hauv lub siab tshwj tsis yog rau gamma globulins
Cov ntshav ntshav ua tiav hauv chav kuaj ntshav li cas?
Qhov kev ntsuam xyuas los txiav txim koj cov ntshav yog hu ua ABO typing. Koj cov ntshav piv nrog cov tshuaj tiv thaiv kab mob ntshav A thiab B. Tom qab ntawd, kuaj tus qauv los saib seb puas muaj cov qe ntshav sib koom ua ke. Yog tias cov qe ntshav nyob ua ke, nws txhais tau hais tias cov ntshav tau hnov mob nrog ib qho ntawm cov tshuaj tiv thaiv
