Qhov sib txawv tseem ceeb ntawm cov qe ntshav liab ib txwm thiab cov kab mob qog noj ntshav yog cov qe ntshav liab ib txwm muaj nyob hauv cov duab, thaum cov qog ntshav yog cov qe ntshav liab distorted muaj cov kab mob.
cov qe ntshav liab yog ib feem tseem ceeb hauv peb cov ntshav. Cov hlwb no nqa oxygen thoob plaws hauv peb lub cev. Lawv kuj thauj thiab tshem tawm carbon dioxide los ntawm peb lub cev. Sickle cell anemia yog ib hom mob ntshav qab zib vim muaj cov qe ntshav liab txawv txav. Qhov xwm txheej tshwm sim feem ntau vim yog qhov tsis xws ntawm caj ces. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau kuaj xyuas cov kab mob cell anemia thaum ntxov hauv lub neej kom tiv thaiv kev tuag.
Lub qe ntshav liab yog dab tsi?
cov qe ntshav liab lossis erythrocytes yog hom qe ntshav hauv tib neeg lub cev. Cov pob txha pob txha yog qhov chaw tsim cov qe ntshav liab. Lawv yog cov cell tiaj tus, uas yog puag ncig. Lawv tshwm li oval biconcave disks. Ntxiv mus, lawv tsis muaj cov nucleus lossis feem ntau cov cell organelles, tshwj xeeb tshaj yog mitochondria. Yog li ntawd, lawv nyob ntawm kev ua pa anaerobic kom ciaj sia.
Daim duab 01: Ntshav liab
Haemoglobin yog ib qho tseem ceeb ntawm cov qe ntshav liab. Cov yam ntxwv xim liab ntawm cov ntshav yog vim muaj cov hemoglobin hauv cov qe ntshav liab. Lub luag haujlwm tseem ceeb ntawm cov qe ntshav liab ib txwm yog thauj cov pa oxygen thiab carbon dioxide hauv lub cev. Lawv khi rau oxygen ntawm oxyhemoglobin thiab carbon dioxide ntawm carbhemoglobin. Hauv qhov no, cov qe ntshav liab pab txhawb kev thauj cov pa pa hauv lub cev. Tsis tas li ntawd, cov qe ntshav liab qis qhia tau tias muaj cov kab mob anemic, metabolic ntshawv siab lossis noj tsis txaus.
Sickle Cell yog dab tsi?
Sickle cell anemia yog ib yam kab mob uas tshwm sim los ntawm kev tsim cov qe ntshav liab txawv txav hu ua sickle cells. Raws li nws lub npe implies, cov kab mob muaj kab mob. Yog li ntawd, cov kab mob kis kab mob tsis zoo. Tsis tas li ntawd, cov kab mob qog nqaij hlav muaj cov hemoglobin S piv rau hom hemoglobin A ib txwm muaj. Yog li ntawd, nrog lub sij hawm, cov kab mob kis mus rau cov hlwb uas nruj dua thiab nplaum. Vim qhov txawv txav ntawm cov qe ntshav liab no, lawv tuaj yeem daig hauv cov hlab ntsha me, ua kom qeeb thiab thaiv cov ntshav. Yog li, peb lub cev yuav tsis tau txais cov pa oxygen txaus, ua rau qaug zog.
Daim duab 02: Cov Ntshav Liab Li Cas vs Sickle Cell
Cov txiaj ntsig ntawm cov qe ntshav liab zoo li mob ua rau mob qog nqaij hlav ntshav. Lawv yog:
- txhaws cov hlab ntsha tuaj yeem ua rau mob ntawm lub cev uas tsis muaj ntshav.
- Txo cov pa oxygenated hemoglobin rau kev thauj.
- Kev puas tsuaj los ntawm tus po. Nws ua rau txo cov qe ntshav liab ua rau muaj ntshav tsis txaus.
Tsis tas li ntawd, mob ntshav qab zib hauv lub cev tuaj yeem ua rau muaj ntau yam teeb meem, suav nrog mob stroke, mob hauv siab mob, pulmonary hypertension, lub cev puas tsuaj thiab dig muag.
Dab tsi yog qhov zoo sib xws ntawm cov qe ntshav liab ib txwm thiab kab mob Sickle?
- Ob leeg yog hom qe ntshav liab.
- Ntxiv mus, lawv nqa oxygen khi rau hemoglobin.
- Lawv tsis muaj nuclei thiab mitochondria.
- Ob leeg ua pa anaerobic.
Dab tsi yog qhov txawv ntawm cov qe ntshav liab ib txwm thiab cov kab mob Sickle?
Qhov sib txawv tseem ceeb ntawm cov qe ntshav liab ib txwm thiab mob qog noj ntshav yog cov duab ntawm lub cell. Qhov ntawd yog; cov qe ntshav liab ib txwm yog puag ncig hauv cov duab thaum lub cev muaj mob muaj kab mob. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm cov qe ntshav liab ib txwm thiab cov kab mob qog nqaij hlav yog cov qe ntshav liab ib txwm hloov tau thaum cov qog nqaij hlav txhav thiab nplaum.
Ntxiv mus, cov qe ntshav liab ib txwm muaj hemoglobin A thiab cov hlwb mob muaj hemoglobin S. Yog li, qhov no yog lwm qhov sib txawv ntawm cov qe ntshav liab ib txwm thiab mob qog noj ntshav.
Cov lus qhia hauv qab no nthuav tawm cov ntaub ntawv ntxiv hais txog qhov sib txawv ntawm cov qe ntshav liab ib txwm thiab mob qog noj ntshav.
Summary – Cov qe ntshav liab li qub vs Sickle Cell
cov qe ntshav liab feem ntau nqa oxygen thiab carbon dioxide hauv cov ntshav khi rau hemoglobin. Txawm li cas los xij, cov xwm txheej xws li mob qog noj ntshav ua rau muaj cov qe ntshav liab txawv txav uas tsis ua haujlwm li qub. Hauv cov ntsiab lus no, cov qe ntshav liab ib txwm hais txog cov qe ntshav liab ib txwm muaj nyob hauv cov duab thiab muaj hemoglobin A. Hauv qhov sib piv, cov hlwb mob xa mus rau cov qe ntshav liab txawv txav uas muaj mob thiab muaj hemoglobin S. Yog li ntawd, qhov no summarizes lub Qhov sib txawv ntawm cov qe ntshav liab ib txwm thiab mob qog noj ntshav.
