Qhov sib txawv tseem ceeb ntawm cov ntshav O zoo thiab O tsis zoo yog cov ntshav O zoo muaj Rh yam hauv lawv cov qe ntshav liab thaum cov ntshav O tsis zoo tsis muaj Rh yam.
Tib neeg cov ntshav tuaj yeem faib ua plaub hom sib txawv raws li cov tshuaj tiv thaiv kab mob hauv cov cell ntawm cov ntshav liab. Xyoo 1900, Landsteiner pom ob hom antigens; hom A thiab B antigens. Yog li, qhov chaw ntawm cov qe ntshav liab ntawm ib tug neeg tuaj yeem muaj antigen A lossis B lossis tsis muaj lawv. Raws li cov kev tshawb pom no, muaj plaub pawg ntshav xws li A, B, AB, lossis O.
Thaum txiav txim siab txog ABO cov ntshav, lwm qhov kev txiav txim siab tseem ceeb yog cov tshuaj tiv thaiv, uas muaj nyob hauv cov ntshav ntshav. Piv txwv li; Yog hais tias cov ntshav liab saum npoo av muaj hom A antigen, cov ntshav ntawm cov ntshav muaj cov tshuaj tiv thaiv kab mob B cov qe ntshav liab thiab rov ua dua. ABO cov ntshav tau txais txiaj ntsig los ntawm peb lub alleles hauv chromosome 09 thiab alleles IA (A), IB (B), thiab ii (O) tau txais txiaj ntsig mus rau tiam thib ob los ntawm txhua tus niam txiv. Ib tug niam txiv tsuas muaj ob tug ntawm peb cov alleles. Alleles IA and IB are dominant over ii (O).
Rhesus Blood Group System yog dab tsi
Rh (Rhesus) pawg ntshav yog ib qho tseem ceeb uas pab pawg ntshav. Qhov muaj lossis tsis muaj Rh antigen ntawm cov cell membrane ntawm cov qe ntshav liab txiav txim siab qhov zoo lossis qhov tsis zoo ntawm cov ntshav. Rh gene encodes rau ob qhov sib txawv antigens C thiab c, E thiab e nrog D, tab sis rau qhov zoo lossis tsis zoo ntawm hom ntshav, tsuas yog D antigen tseem ceeb. Hauv kev tso ntshav, thaum Rh zoo ntshav muab rau tus neeg Rh-negative, nws ua rau muaj kev tsis sib haum xeeb. Txawm li cas los xij, qhov kev hloov pauv no tuaj yeem ua tau rau thawj zaug. Feem ntau, lub cev tiv thaiv kab mob tsim Rh antigens hauv tus neeg Rh-negative lub cev thiab kev hloov pauv ntawm Rh-positive tom ntej yuav ua rau kev puas tsuaj ntawm cov ntshav. Yog li, kev hloov ntshav Rh-positive rau Rh-negative ntshav tsis tuaj yeem ua tau zaum ob.
O Dab Tsi yog Ntshav Zoo?
Alleles ntawm ii txiav txim siab hom ntshav O zoo. Nws tsis muaj cov antigens nyob rau hauv cov ntshav liab nto. Txawm li cas los xij, cov neeg uas muaj ntshav O muaj cov tshuaj tiv thaiv A thiab cov tshuaj tiv thaiv B hauv cov ntshav, uas ua rau cov ntshav hom A thiab hom B ntshav.
Daim duab 01: Cov Ntshav
Feem ntau, tus neeg muaj ntshav O tuaj yeem txais cov ntshav los ntawm tus neeg uas tsuas muaj ntshav O. Yog tias tus neeg tau txais cov ntshav O zoo, tus neeg pub dawb tuaj yeem yog O zoo lossis O tsis zoo. Cov neeg muaj txiaj ntsig zoo tuaj yeem muab cov ntshav rau cov tib neeg muaj A zoo, B zoo, AB zoo, lossis O zoo ntshav.
Cov Ntshav Tsis Zoo yog dab tsi?
Ib yam alleles ntawm ii txiav txim siab hom O tsis zoo ntshav. Tab sis nws tsis muaj Rh yam thiab ob qho tib si anti-A tshuaj tiv thaiv thiab anti-B tshuaj tiv thaiv hauv plasma. Yog li, hom O tsis zoo tuaj yeem muab kev nyab xeeb rau txhua pawg ntshav, hom A zoo thiab tsis zoo, B zoo thiab tsis zoo, AB tsis zoo thiab O tsis zoo, thiab lwm yam. Li no, peb tuaj yeem txiav txim siab O cov ntshav tsis zoo li tus neeg pub dawb thoob ntiaj teb.
Tab sis O pab pawg ntshav tsis zoo tuaj yeem txais cov ntshav los ntawm tib cov ntshav O tsis zoo.
Dab tsi zoo sib xws ntawm O Positive thiab O Negative Blood Group?
- O Positive thiab O Negative yog ob hom ntshav.
- Ob pawg ntshav yog txiav txim los ntawm tib qho alleles ii.
- Tsis tas li, ob pawg ntshav no tsis muaj cov tshuaj tiv thaiv-A thiab tiv thaiv-B antigens ntawm lawv cov qe ntshav liab.
- Dhau li, cov ntshav O zoo thiab O tsis zoo tuaj yeem pub dawb rau ntau pawg ntshav.
Dab tsi yog qhov txawv ntawm O Positive thiab O Negative Blood Group?
Qhov sib txawv tseem ceeb ntawm O zoo thiab O tsis zoo yog cov ntshav O zoo muaj Rh yam ntawm lawv cov cell membranes ntawm cov qe ntshav liab thaum O tsis zoo cov ntshav tsis muaj Rh yam. Tsis tas li ntawd, hom O zoo muaj cov tshuaj tiv thaiv kab mob; Nws muaj ob hom tshuaj tiv thaiv A thiab cov tshuaj tiv thaiv B hauv plasma uas ua tawm tsam hom A ntshav thiab ntshav hom B, thaum O cov ntshav tsis zoo tsis muaj cov tshuaj tiv thaiv A thiab cov tshuaj tiv thaiv B hauv cov ntshav. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm O zoo thiab O tsis zoo.
Ntxiv mus, qhov sib txawv ntxiv ntawm O zoo thiab O tsis zoo yog tias hom O zoo ntshav tuaj yeem muab rau cov neeg muaj A zoo, B zoo, AB zoo, thiab O cov ntshav zoo, thaum O tus neeg tsis zoo tuaj yeem pub dawb. ntshav rau leej twg. Yog li, hom O tsis zoo ntshav yog ib tus neeg pub dawb thoob ntiaj teb thaum O zoo tsis yog. Yog li thaum muaj xwm txheej ceev, leej twg tuaj yeem muab cov ntshav O tsis zoo. Tsis tas li ntawd, O pawg ntshav zoo nyob txog li 37% ntawm cov pejxeem thaum O tsis zoo yog qhov tsawg thiab tsuas yog pom hauv 6.6% ntawm cov pejxeem xwb. Li no, peb tuaj yeem xav txog qhov no ib yam li qhov sib txawv ntawm O zoo thiab O tsis zoo.
Cov duab hauv qab no qhia txog qhov sib txawv ntawm pawg O zoo thiab O tsis zoo.
Summary – O Positive vs O Negative Blood Group
Nyob rau hauv kev qhia txog qhov sib txawv ntawm O zoo thiab O tsis zoo cov ntshav, cov ntshav O zoo muaj Rh yam nyob rau saum npoo ntawm cov ntshav liab thaum cov ntshav O tsis zoo tsis muaj Rh yam. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm pawg O zoo thiab O tsis zoo. Tsis tas li ntawd, O tsis zoo yog ib pawg ntshav tsawg heev; Nws nyob tsuas yog 6.6% ntawm cov pej xeem thaum O zoo cov ntshav muaj ntau thiab nws nyob 37% ntawm cov pejxeem. Ntxiv mus, O tsis zoo yog tus neeg pub dawb thoob ntiaj teb, txhais tau tias O cov ntshav tsis zoo tuaj yeem hloov mus rau txhua tus thaum O cov ntshav zoo tuaj yeem pub rau cov neeg muaj A zoo, B zoo, A zoo thiab O zoo. Qhov tseem ceeb, pab pawg ntshav O zoo tuaj yeem tau txais cov ntshav los ntawm O zoo thiab O tsis zoo thaum tus neeg muaj ntshav O tsis zoo tsuas tuaj yeem txais cov ntshav los ntawm lwm tus neeg uas muaj ntshav O tsis zoo.
