Cov hom ntawm oligosaccharides tam sim no rau ntawm qhov liab ntshav cell txiav txim siab tus neeg hom ntshav : yog tias tsuas yog 0- hom antigen yog tam sim no, tus hom ntshav yog 0, yog tsuas yog pom antigen A lossis B, tus ntshav yog hom A lossis B, feem, thiab yog tias ob qho tib si A thiab B antigens muaj, tus hom ntshav AB [1].
Hauv qhov no, lub luag haujlwm ntawm oligosaccharides hauv kev sau ntshav yog dab tsi?
Tib neeg ntshav Cov pab pawg nyob ntawm kev ua haujlwm ntawm glycosyltransferases, enzymes uas ua rau kev tsim cov glycosidic bond ntawm cov qauv thiab muaj nuj nqi ntawm tib neeg ntshav . Tshwj xeeb oligosaccharide hmoov antigens txuas rau cov protein thiab lipid nyob rau saum npoo ntawm erythrocytes.
li cas carbohydrates cuam tshuam nrog pab pawg ntshav? The ABO Ntshav Hom Txheej txheem. Ib lub luag haujlwm loj carbohydrates ua si hauv hlwb yog nyob rau hauv cell-cell paub. Cov enzymes tshwj xeeb tsim los ntawm ABO cov noob txuas ntxiv monosaccharides rau H antigen, thiab ua tiav carbohydrates txiav txim tus neeg ntawd hom ntshav.
Tsuas yog li ntawd, koj yuav ua li cas sib txawv cov qauv biochemical ntawm plaub hom tib neeg cov ntshav sib txawv?
Qhov muaj lossis tsis muaj A lossis B antigens muab peb plaub hom ntshav tseem ceeb:
- Hom ntshav tsuas muaj A antigens ntawm cov qe ntshav liab.
- Cov ntshav hom B tsuas muaj B antigens ntawm cov qe ntshav liab.
- AB muaj ob qho tib si A thiab B antigens ntawm cov qe ntshav liab.
- O tsis muaj A lossis B antigens ntawm cov qe ntshav liab.
Dab tsi txiav txim siab hom ntshav?
Hom ntshav tau txiav txim siab los ntawm qhov muaj lossis tsis muaj cov antigens tshwj xeeb ntawm cov qe ntshav liab. Muaj yim hom ntshav tseem ceeb: Zoo, Tsis zoo, B zoo, B tsis zoo, AB zoo, AB tsis zoo, O zoo thiab O tsis zoo. Qhov zoo thiab tsis zoo hais txog koj hom Rh (ib zaug hu ua Rhesus).

Cov txheej txheem twg ntawm kev kawm lub hlwb cuam tshuam nrog kev txhaj tshuaj rau tus neeg mob nrog cov piam thaj hauv ntshav?
Lub paj hlwb positron emission tomography (PET) scan yog kev ntsuas duab uas tso cai rau cov kws kho mob pom tias koj lub hlwb ua haujlwm zoo li cas. Kev tshuaj xyuas ntes cov duab ntawm kev ua haujlwm ntawm lub hlwb tom qab cov tshuaj tiv thaiv kab mob "tracers" tau nqus mus rau hauv cov ntshav. Cov neeg taug kev no "txuas" rau cov sib txuas zoo li qab zib (qab zib)
Dab tsi yog qee yam ntawm cov kab mob loj hauv kev cuam tshuam nrog cov hlab ntshav ncig?
Kab mob hauv lub plawv Coronary artery disease. Atherosclerosis, arteriosclerosis, thiab arteriolosclerosis. Mob stroke. Mob ntshav siab. Lub plawv tsis ua hauj lwm. Aortic dissection thiab aneurysm. Myocarditis thiab pericarditis. Cardiomyopathy
Cov tshuaj hormones thiab neurotransmitters cuam tshuam rau tib neeg tus cwj pwm li cas?
Endocrine cells hauv lub hlwb cuam tshuam rau kev ua kom zoo ntawm tus cwj pwm. Biochemical messenger tshuaj nyob rau hauv lub hlwb los yog hu ua neurotransmitters ua lub luag haujlwm tseem ceeb hauv cov txheej txheem hloov pauv sai. Peb paub tias cov tshuaj hormones kuj muaj kev tswj hwm kev ntxhov siab, tab sis lawv cov kev cuam tshuam tau pom qeeb dua
Qhov twg ntawm cov hauv qab no tuaj yeem cuam tshuam nrog ncua cov hlua txuas hauv cov menyuam mos uas tsis muaj zog?
Ncua qaum qaum clamping yog txuam nrog cov txiaj ntsig tseem ceeb hauv cov menyuam mos yug ntxov ntxov, suav nrog kev hloov pauv hloov pauv, txhim kho cov ntshav liab kom zoo dua qub, txo qis kev xav tau ntawm cov ntshav, thiab txo qis qhov tshwm sim ntawm necrotizing enterocolitis thiab intraventricular hemorrhage
Cov ntshav viscosity cuam tshuam li cas rau cov ntshav khiav?
Ua kom muaj viscosity nce qhov ua haujlwm ntawm cov ntshav khiav thiab yog li ua kom lub plawv ua haujlwm thiab ua rau lub cev tsis muaj zog. Ib yam li cov suab thaj, thaum ntshav tau txias, nws dhau los ua 'tuab' thiab ntws qeeb dua. Yog li ntawd, muaj kev cuam tshuam sib txawv ntawm qhov kub thiab viscosity
