Spherocytosis ua rau cov qe ntshav liab kom dhau los ua tus kheej yog li lawv tsis tuaj yeem hloov pauv kom tau txais los ntawm cov hlab ntsha me.
Tsis tas li, vim li cas cov qe ntshav liab hloov pauv?
Tib neeg cov qe ntshav liab maj nrawm los ntawm lub cev kom nqa cov pa oxygen thiab carbon dioxide mus thiab los ntawm lub cev raug yuam kom nyem los ntawm qhov me me thiab me dua ntshav nkoj. Rau hloov cov duab , cov hlwb rov tsim cov khoom sib txuas ntawm cov protein ntawm lawv sab hauv scaffolding, hu ua cytoskeleton.
Ib tus kuj yuav nug, dab tsi tuaj yeem ua rau cov qe ntshav liab me me? Yog tias cov qe ntshav liab yog me dua dua li ib txwm, qhov no hu ua microcytic anemia. Qhov loj ua ntawm hom no yog hlau tsis txaus (qib hlau qis) anemia thiab thalassemia (cov teeb meem qub txeeg qub teg ntawm hemoglobin).
nws txhais li cas thaum koj cov qe ntshav hloov pauv?
RBCs nqa oxygen thiab cov as -ham rau koj lub cev nqaij daim tawv thiab lub cev. Yog koj RBCs yog cov duab tsis xwm yeem, lawv yuav tsis tuaj yeem nqa cov pa txaus. Poikilocytosis feem ntau yog tshwm sim los ntawm lwm yam mob, xws li ntshav tsis txaus, mob siab, haus dej cawv, lossis tau txais txiaj ntsig ntshav tsis meej pem.
Dab tsi ua rau cov qe ntshav liab txawv txav?
Vim yog kev hloov pauv caj ces, tus cov qe ntshav liab ntawm cov neeg uas muaj kab mob cell anemia muaj txawv txav hemoglobin molecules, uas ua rau lawv nruj thiab nkhaus. Lub siab- zoo li cov qe ntshav liab tsis tuaj yeem nqa cov pa oxygen ntau rau koj cov ntaub so ntswg li qub cov qe ntshav liab tau.

Yam twg ntawm cov hauv qab no yog qhov hloov pauv hloov pauv tau rau kev mob pob txha?
Yam yuav hloov pauv tau yam muaj xws li: Dej cawv. Kev haus luam yeeb. Low Body Mass Index. Kev noj zaub mov tsis zoo. Vitamin D tsis txaus. Kev noj zaub mov tsis zoo. Estrogen tsis muaj peev xwm. Kev tawm dag zog tsis txaus
Dab tsi DNA hloov pauv ua rau mob qog ntshav ntshav ntshav?
Tus kab mob Sickle cell yog tshwm sim los ntawm kev hloov pauv hauv hemoglobin-Beta gene pom ntawm chromosome 11. Hemoglobin thauj oxygen los ntawm lub ntsws mus rau lwm qhov ntawm lub cev. Cov qe ntshav liab uas muaj hemoglobin ib txwm muaj (hemoglobin-A) yog du thiab puag ncig thiab glide los ntawm cov hlab ntsha
Qhov kev hloov pauv twg yuav ua rau hloov mus rau sab laug hauv cov pa oxygen hemoglobin khi nkhaus?
Cov pa -hemoglobin kev sib cais sib cais tuaj yeem txav chaw xws li qhov kev sib raug zoo rau cov pa oxygen tau hloov pauv. Cov yam ntxwv uas hloov qhov nkhaus muaj xws li kev hloov pauv hauv cov pa roj carbon dioxide concentration, ntshav kub, ntshav pH, thiab cov concentration ntawm 2,3-diphosphoglycerate (2,3-DPG)
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
Kev hloov pauv hloov pauv yog dab tsi?
Kev hloov pauv hloov pauv hloov pauv ntawm cov khoom nruab nrog nruab nrab ntawm ob tsev neeg, uas tsis tuaj yeem pub khoom nruab nrog cev rau lawv tsev neeg vim yog pawg ntshav tsis sib haum. Qhov no yog nyob rau hauv kev nkag siab 'khub pauv'
