Imitha yeHemoglobin

I-Erythrin yiprotheyini (efinyeziweyo njenge-Hb okanye i-HGB) enoxanduva lokuthutha ioksijini kwizinto eziphilayo eziphezulu.Yiprotheyini eyenza igazi lijike libebomvu.IHemoglobin yenziwe ngamatyathanga amane, amabini α Chain kunye amabini β Chain, ikhonkco ngalinye lineheme ye-cyclic equlethe i-athomu yentsimbi enye.Ioksijini ibophelela kwiiathom zentsimbi kwaye ithuthwa ngegazi.Iimpawu ze-hemoglobin zezi: kwiindawo ezinomxholo ophezulu we-oksijeni, kulula ukudibanisa ne-oxygen;Kwiindawo ezine-oksijini ephantsi, kulula ukuhlukana ne-oxygen.Olu phawu lwehemoglobin lwenza ukuba iiseli ezibomvu zegazi zikwazi ukuthutha ioksijini.
Ukubaluleka kweklinikhi-Ukwahluka ngokwasemzimbeni kunye ne-pathological ye-hemoglobin ziphantse zifana nezo zeeseli ezibomvu zegazi.Nangona kunjalo, ukuncipha kweeseli ezibomvu zegazi kunye ne-hemoglobin isenokungabi nobudlelwane obufanayo kwiindidi ezahlukeneyo ze-anemia.
1. Ukunyuka ngokwasemzimbeni
Abantwana abasandul 'ukuzalwa, abahlali bethafa, njl.
2. Ukunyuka kwePathological
I-polycythemia yokwenyani, ukuphelelwa ngamanzi emzimbeni okubangelwa zizizathu ezahlukeneyo, isifo sentliziyo esizelwe, isifo sentliziyo yemiphunga, njl.
3. Ukunciphisa
Iindidi ezahlukeneyo ze-anemia (ezifana ne-aplastic anemia, i-anemia yokunqongophala kwesinyithi, i-sideroblastic anemia, i-megaloblastic anemia, i-anemia ye-hemolytic, i-thalassemia, njl.), ukulahleka kwegazi okukhulu (njengokopha okubuhlungu, ukopha ngotyando, ukopha kwasemva kokubeleka, ukopha kwesisu esibuhlungu, igazi elingapheliyo. ilahleko ebangelwa zizilonda, njl.), i-leukemia, i-postpartum, i-chemotherapy, isifo se-hookworm, njl.
Isihlalutyi seHemoglobin
Iisampulu zegazi elincinane: Kuphela ithontsi elinye lesampulu yegazi elifunekayo ukuze kugqitywe uvavanyo
Isantya kunye nokuchaneka: ukufumanisa ngokukhawuleza kunye nokufunda kweziphumo;Iziphumo zichanekile kwaye zinonxibelelwano oluhle kunye nendlela yesalathiso ye-ICSH
Ukufumanisa ubungakanani: bonisa ngokuthe ngqo umxholo we-hemoglobin kunye ne-hematocrit emzimbeni
Ukusebenza ngokulula: Akukho mfuneko yokulinganisa ngesandla, imicu yovavanyo eyahlukeneyo inokutshintsha ngokuzenzekelayo iikhowudi ngekhadi leCODE
Ukuhanjiswa kwedatha: Umsebenzi wokuhanjiswa kwedatha unokuxhotyiswa ngokweemfuno zabathengi.
