Wali olowoozezza nti omusaayi oguli munda mu mubiri gwaffe gugenda guzzibwa obuggya buli kiseera? Omubiri gwaffe mu butuufu kkolero lya kyewuunyo. Omulimu ogusinga obukulu ogubeera mu kkolero lino olunaku lwonna kwe kukola obutoffaali obumyufu, kwe kugamba, obutoffaali obumyufu obuli mu musaayi. Bw’oba bulijjo owulira ng’okooye era nga tolina bulamu, ensonga eyinza okuba nga ya butakola butoffaali bumyufu. Kale leero tugenda kwogera ku nkola eno eyeewuunyisa, nga eno ye ‘erythropoiesis’.
Mu ngeri ennyangu, erythropoiesis kye ki?
Erythropoiesis y’enkola omubiri gwaffe mwe gukola obutoffaali obumyufu oba erythrocytes mu ngeri y’obusawo. Kino kiringa maama waffe bw’afumba emmere empya ng’emmere etuweddeko. Obutoffaali obumyufu obukadde mu mubiri gwaffe bufa oluvannyuma lw’akaseera. Kale, enkola eno y’ekola obutoffaali obumyufu obupya mu kifo ky’ekyo.
Kino kikuuma omuwendo gw’obutoffaali obumyufu mu mubiri gwaffe nga guli ku mutindo omutuufu, nga tegweyongera wadde okukendeera ekisusse.
Kale lwaki obutoffaali obumyufu bukulu nnyo gye tuli?
Teebereza empeereza y’okutuusa ebintu etuusa ebintu mu mubiri gwo gwonna. Obutoffaali obumyufu bwe bukola ekyo kyennyini.
- Okutuusa Oxygen: Bwe tussa, omukka oguyingira mu mawuggwe gaffe gutwalibwa mu buli katoffaali n’ebitundu by’omubiri mu mubiri gwaffe obutoffaali buno obumyufu. Okuva ku bwongo okutuuka ku bigere, buli kimu kyetaaga omukka gwa oxygen okusobola okuwangaala.
- Okuggyawo kaboni dayokisayidi: Ate era, kaboni dayokisayidi, kasasiro afuluma mu butoffaali bwaffe, akuŋŋaanyizibwa n’azzibwa mu mawuggwe tusobole okumuggya mu mubiri nga tufulumya omukka.
Mu ngeri ennyangu, awatali butoffaali bumyufu, obutoffaali bw’omubiri gwaffe tebusobola kuwangaala.
Erythropoiesis kitundu kimu kyokka ku nkola okutwalira awamu ey’okukola omusaayi mu mubiri gwaffe, ekiyitibwa ‘hematopoiesis.’ Enkola eno okutwalira awamu ekola ebika byonna ebisatu eby’obutoffaali: obutoffaali obumyufu, obutoffaali obweru, n’obutoffaali obuyitibwa platelets.
Enkola eno ebeera wa mu mubiri?
Ekifo obutoffaali buno obumyufu we bukolebwa kikyuka okumala ekiseera.
Nga omwana ali mu lubuto (Fetal Erythropoiesis) .
Omusaayi gutandika okutondebwa mu mibiri gyaffe ne bwe tuba nga tetunnazaalibwa.
- Ku wiiki 3: Omusaayi gutandika okutondebwa mu nsengeka eyitibwa ‘yolk sac’, egaba embuto emmere yaayo esooka.
- Ku myezi 2-3: Okutondebwa kw’omusaayi kubaawo mu kibumba n’ennywanto y’omwana ali mu lubuto.
- Oluvannyuma lw’emyezi 5: Omusaayi gutandika okutondebwa mu busimu bw’amagumba g’omwana ali mu lubuto.
Abaana n’abantu abakulu
Bwe tumala okuzaalibwa, obusimu bwaffe obw’amagumba bufuuka ekkolero erisinga okukola obutoffaali obumyufu. Kino kye kitundu ekigonvu era ekiringa sipongi munda mu magumba gaffe.
- Mu buto: Omusaayi gukolebwa mu magumba g’amagumba amanene mangi ag’omubiri.
- Mu bukulu: Omusaayi gusinga kukolebwa mu busimu bw’amagumba g’amagumba amatono ag’enjawulo , gamba ng’amagumba g’ekisambi, emigongo gy’omugongo, embiriizi, n’eggumba eripapajjo wakati mu kifuba (eggumba ly’amabeere).
Olugendo lw’obutoffaali obumyufu
Kino tekibaawo kiro kimu. Akatoffaali akamyufu akamu kalina okuyita mu mitendera egiwerako okusobola okukula mu bujjuvu, kwe kugamba, okusobola okukola. Olugendo lwonna lutwala wiiki nga emu .
Byonna bitandikira ku katoffaali ak’enjawulo akayitibwa ‘Hematopoietic Stem Cell’ (HSC). Kino kiringa ensigo. Ensigo eno esobola okukula n’efuuka ekintu kyonna okuva ku butoffaali obumyufu, obutoffaali obweru, n’obutoffaali obuyitibwa platelets. Okufuuka akatoffaali akamyufu, akatoffaali kano kayita mu mitendera egiwerako.
Omulongooti guno wansi gusobola okukuyamba okutegeera obulungi olugendo luno.
| Siteeji | Ennyinyonnyola ennyangu |
|---|---|
| Obutoffaali obusibuka (Hematopoietic Stem Cell - HSC) . | Eno y’ensibuko ya buli katoffaali k’omusaayi, ng’ensigo ekimera mwe kiva. |
| Ekirungo ekiyitibwa Proerythroblast | Omutendera ogusooka ogukakafu mu lugendo lw’okufuuka obutoffaali obumyufu. |
| Ensengekera y’omubiri (erythroblast). | Akatoffaali kakendeera mpolampola ne katandika okukola hemoglobin, puloteyina etambuza omukka gwa oxygen. |
| Ensigo ya Normoblast | Mu mutendera guno, ekitundu ky’obutoffaali kiggyibwamu, ne kisobozesa obutoffaali okujjula hemoglobin omungi. |
| Obuwuka obuyitibwa reticulocyte | Buno butoffaali bumyufu obutakuze. Wano we zifuluma okuva mu busimu bw’amagumba ne ziyingira mu musaayi. |
| Ensigo z’omubiri (Erythrocyte). | Obutoffaali obumyufu obukuze mu bujjuvu, nga bwetegefu okutambuza omukka gwa oxygen. |
Obulamu bw'obutoffaali obumyufu obukolebwa mu ngeri eno buba bwa nnaku nga 120 . Okufaananako bbaatule, obutoffaali buno bufa oluvannyuma lw’ennaku 120 nga bukozesebwa. Eno y’ensonga lwaki emibiri gyaffe buli kiseera girina okukola obutoffaali obumyufu obupya.
Omubiri gumanyi gutya okukola omusaayi?
Eno nkola ya kufuga eyeewuunyisa nnyo. Omubiri gwaffe gufuga okukola obutoffaali obumyufu okusinziira ku mutindo gwa oxygen mu mubiri.
Kuba akafaananyi ng’ogenda mu kitundu eky’ensozi empanvu nga Nuwara Eliya. Bw’ogenda okulinnya, owulira ng’okaluubirira katono okussa, nedda? Kino kiri bwe kityo kubanga omukka gwa oxygen mu mpewo guba mutono. Olwo obungi bwa oxygen atuuka mu bitundu by’omubiri gwaffe ne gufuuka ogutamala. Embeera eno tugiyita hypoxia .
Wano ensigo zaffe we zikola .
Ensigo ze zilondoola buli kiseera omukka gwa oxygen mu musaayi gwaffe. Bwe bawulira nti omukka gwa oxygen mutono, ensigo zifulumya obusimu obw’enjawulo (chemical messenger) obuyitibwa Erythropoietin (EPO) mu musaayi.
Laba engeri enkola eno gy’ekola:
1. Ebitundu byo tebifuna mukka gwa oxygen gumala.
2. Mu kwanukula ‘akabonero’ ako, enkizi zifulumya obusimu obusingako obuyitibwa `(EPO)`.
3. Obusimu buno (EPO) butambula mu musaayi ne "byogera" n'obusimu bw'amagumba, nga bugamba nti "mu bwangu, kola obutoffaali obumyufu obulala!"
4. Yanguya okukola obutoffaali obumyufu mu busimu bw’amagumba.
5. Obutoffaali obumyufu obupya obutondeddwa buzzaayo omukka gwa oxygen mu musaayi mu mbeera eya bulijjo.
6. Oxygen bw’emala okudda mu mbeera eya bulijjo, ensigo zikendeeza ku kufulumya EPO.
Emibiri gyaffe mulungi nnyo mu kukuuma buli kimu nga kiri mu bbalansi (homeostasis) mu ngeri eno. Bakuuma omutindo omutuufu, nga tebagukkiriza kugenda waggulu nnyo wadde wansi nnyo.
Kiki ekibaawo singa enkola eno egenda bubi?
Oluusi enkola eno ey’okukola obutoffaali obumyufu eyinza okutambula obubi. Olwo ebizibu bibiri ebikulu biyinza okuvaamu. Oba obutoffaali obumyufu butono nnyo, oba bungi nnyo.
| Kakwakkulizo | Simply amakulu | Mode/engeri ezikoseddwa |
|---|---|---|
| Okukendeera kw’omusaayi | Omuwendo gw’obutoffaali obumyufu obutono (anemia). | Omubiri gufiirwa obutoffaali obumyufu obumala okutambuza omukka gwa oxygen. Kino kiyinza okuvaako obubonero ng’okukoowa ennyo, okunafuwa, okufuuka omumyufu, okussa obubi, n’okuwulira ennyonta mu ngeri etaali ya bulijjo . |
| Obulwadde bw’okuzimba omubiri (erythrocytosis). | Okwongera ku muwendo gw’obutoffaali obumyufu (okweyongera kw’obugumu bw’omusaayi). | Omusaayi bwe gugenda gugonvuwa, okutambula kw’omusaayi kuyinza okulemesebwa. Obubonero ng’okulumwa omutwe, obukoowu n’okuziyira buyinza okubaawo. Mu mbeera ezimu, wabaawo akabi k’okuzimba omusaayi mu ngeri ey’akabi . |
Bw’oba olina obubonero nga buno, kikulu nnyo okulaba omusawo n’okufuna amagezi nga tolina ky’osalawo ku bubwo.
Ebintu ebiyinza okukosa okukola obutoffaali obumyufu
Enkola eno esobola okukosebwa embeera z’endwadde ez’enjawulo n’ensonga endala.
Endwadde ezeekuusa ku mawuggwe
Bw’oba n’endwadde z’okussa eziwangaala nga asima ne COPD, omukka gwa oxygen omubiri gwo gwe gufuna gukendeera. Omubiri gugezaako okukola obutoffaali obumyufu obulala okusobola okuliyirira.
Kookolo w’omusaayi n’amagumba
Mu mbeera za kookolo nga leukemia ne lymphoma, enkola ya bulijjo ey’obusimu bw’amagumba etaataaganyizibwa. N’ekyavaamu, okukola obutoffaali obumyufu kuyinza okukendeera oba obutoffaali obutali bwa bulijjo.
Ensonga endala
- Ebbula ly’emmere: Okusobola okukola omusaayi omulungi, weetaaga ebirungo ebirungi. Ekyuma, vitamiini B12 ne folate bye biriisa ebikulu. Bino bw’otobifuna bimala ng’oyita mu mmere gy’olya, omubiri gwo tegusobola kukola bulungi butoffaali bumyufu ekivaako okukendeeza ku musaayi.
- Obulwadde bw’ekibumba:Okuva obusimu obuyitibwa hormone `(EPO)` bwe bukolebwa ensigo, singa ensigo eyonoonese, okukola `(EPO)` kuyinza okukendeera era n'okukola obutoffaali obumyufu nakyo kiyinza okukosebwa.
Obubaka Obutwala Awaka
- Enkola y’okukola obutoffaali obumyufu oba erythropoiesis, kintu kya kitalo ekibaawo buli kiseera era mu mibiri gyaffe mu ngeri ey’otoma.
- Enkola eno efugibwa okusinga obusimu obuyitibwa EPO, obufulumizibwa ensigo.
- Bw’oba buli kiseera olaba obubonero ng’okukoowa, okufuuka omuddugavu, n’okussa obubi, kiyinza okuba akabonero k’okukendeeza ku musaayi . Mu mbeera ng’eyo, kakasa nti olaba omusawo akuwe amagezi.
- Okulya emmere ennungi erimu ekyuma (ennyama, ebyennyanja, ebinyeebwa, sipinaki), vitamiini B12 (amata, amagi), ne folate (enva endiirwa eza kiragala, ebinyeebwa) kikulu nnyo okukuuma obutoffaali obumyufu obulungi.
