Wali weebuuzizzaako omusaayi guno oguli munda mu mubiri gwaffe gye guva n’engeri gye gukolebwamu? Tumanyi omusaayi guno bwe guli omukulu okutukuuma nga tuli balamu, okutukuuma endwadde, n’okutwala omukka gwa oxygen mu bitundu by’omubiri byaffe byonna. Kale leero tugenda kwogera ku nkola eno eyeewuunyisa, kwe kugamba, omubiri gwaffe gukola obutoffaali obupya obw’omusaayi ku bwagwo. Kiringa ekkolero ettono munda mu mubiri.
Okukola omusaayi kye ki?
Mu ngeri ennyangu, Hematopoiesis y’enkola y’okukola obutoffaali bw’omusaayi munda mu mibiri gyaffe. Obutoffaali bw’omusaayi obukadde bwe bufa, buli kiseera obutoffaali obupya bulina okukolebwa okusobola okudda mu kifo kyabwo. Awatali bo, omusaayi gwaffe gujja kugwa mu kabi. Enkola eno etandika nga tetunnazaalibwa era egenda mu maaso mu nsengekera mu bulamu bwaffe bwonna.
Ekigambo kino kiyinza okuwulikika ng’ekizibu katono, naye amakulu gaakyo mangu nnyo. Kikolebwa ebigambo bibiri eby’Oluyonaani:
- Haîma (Haima): kitegeeza "omusaayi".
- Poiēsis: kitegeeza "okukola ekintu".
Kati otegedde, nedda? Ebigambo bino ebibiri bwe bigattibwa awamu, bitegeeza "okutondebwa kw'omusaayi." Oluusi ebigambo nga `(hemopoiesis)` ne `(hematogenesis)` nabyo bikozesebwa ku kino.
Bika ki ebikulu eby’obutoffaali bw’omusaayi obukolebwa enkola eno?
Omusaayi gwaffe gukolebwa okukuŋŋaanyizibwa kw’obutoffaali obw’ebika eby’enjawulo. Ebika by’obutoffaali bino byonna bikolebwa mu nkola y’okukola omusaayi. Ka tulabe ebika ebikulu bye biruwa n’emirimu gyabyo gye biri.
| Ekika ky’obutoffaali bw’omusaayi | Omulimu guno mwangu. |
|---|---|
| Obutoffaali Obumyufu oba Erythrocytes | Zino ze ‘delivery service’ eziggya omukka gwa oxygen mu mawuggwe gaffe n’agutwala mu buli kitundu ekirala n’obutoffaali mu mubiri. Era zitwala kasasiro wa kaboni dayokisayidi akolebwa obutoffaali okudda mu mawuggwe. Omusaayi gwaffe gwe gusinga okubaamu obutoffaali obumyufu. Enkola y'okukola bino eyitibwa Erythropoiesis . |
| Obutoffaali bw’omusaayi obweru oba Leukocytes | Zino ze ‘ggye’ ly’omubiri gwaffe. Obutoffaali buno obweru mu musaayi butukuuma obutakwatibwa ndwadde nga bulwanyisa endwadde z’abagwira ng’obuwuka, obuwuka, n’akawuka. Era ziyamba okusaanyaawo obutoffaali obutali bwa bulijjo obutondebwa munda mu mubiri. Enkola y'okuzikola eyitibwa leukopoiesis . |
| Platelets oba Thrombocytes | Teebereza ekyandibaddewo singa osala omukono. Oluvannyuma lw’akaseera, omusaayi gukoma, nedda? Ekyo platelets kye ziyambako. Bino bitundutundu bya butoffaali ebikwatagana. Bwe wabaawo ekiwundu, zikuŋŋaana ne zikola ekizimba, ne ziyimiriza omusaayi. Enkola y'okukola bino eyitibwa thrombopoiesis . |
Waliwo ebika by’obutoffaali obweru?
Yee, nga bwe kiri mu magye gaffe, waliwo ebika by’obutoffaali obweru obw’enjawulo. Buli omu alina omulimu ogw’enjawulo gw’alina okukola. Ebika ebikulu bye bino:
- Ebirungo ebiyitibwa Neutrophils
- Ebiwuka ebiyitibwa Basophils
- Ebirungo ebiyitibwa Eosinophils
- Ebiwuka ebiyitibwa Monocytes
- Lymphocytes - Zino byongera okugabanyizibwamu obutoffaali bwa B, obutoffaali bwa T, n’obutoffaali bwa Natural Killer.
Mu butuufu okutondebwa kw’omusaayi kuno kubaawo wa?
Ekkolero erisinga okukola obutoffaali buno eri munda mu busimu bwaffe obw'amagumba . Obusigo bw’amagumba bwe bitundu ebigonvu era ebiringa sipongi munda mu magumba gaffe amanene. Obutoffaali bw’omusaayi bukolebwa mu busimu bw’amagumba, oluvannyuma ne bwegatta ku misuwa gyaffe.
Wadde omusaayi mu budde obutuufu gukolebwa mu busimu bw’amagumba, mu mbeera ezimu ez’enjawulo, okugeza, singa obusigo bw’amagumba bufuna obulwadde obubulemesa okukola omusaayi, ebitundu by’omubiri ng’ekibumba kyaffe n’ennywanto nabyo bisobola okutandika okuvaamu omusaayi.
Naye ebifo omusaayi guno we gukolebwa byawukana katono nga tetunnazaalibwa n’oluvannyuma lw’okuzaalibwa.
Nga tannazaalibwa (mu mutendera gw’omwana ali mu lubuto) .
Mu wiiki ezisooka ez’olubuto, omusaayi gukolebwa mu nsengeka eyitibwa ensawo y’enkwaso. Olwo ng’olubuto lugenda mu maaso, omulimu guno gukyusibwa ne gutwalibwa mu kibumba n’ennywanto. Omwezi nga ogw’okutaano ng’olubuto luweza, omusaayi gutandika okukolebwa okusinga mu busimu bw’amagumba.
Oluvannyuma lw’okuzaalibwa
Okuva ku lunaku lwe tuzaalibwa okutuuka mu bukulu, obusigo bw’amagumba bwe businga okukola obutoffaali bw’omusaayi. Wabula ekika ky’obutoffaali obweru obuyitibwa lymphocytes nakyo kikula mu bifo nga thymus, ekitundu ku nkola y’amazzi, ng’oggyeeko obusigo bw’amagumba.
Enkola y’okukola omusaayi (hematopoiesis) ebaawo etya?
Enkola eno yonna etandika n’akatoffaali kamu ak’enjawulo. Kino kiyitibwa obutoffaali obukola omusaayi (HSC).Kino ka tukiyite "obutoffaali bwa maama" oba "obutoffaali obusookerwako." Akatoffaali kano maama kasobola okufuuka akatoffaali akamyufu, akatoffaali akazungu, akataffaali akayitibwa platelet, ekika kyonna eky’obutoffaali.
Kino kirowoozeeko ng’ekikuta ky’ebbumba. Nga bwe kiri mu kubumba, ekikuta ky’ebbumba kiyinza okukozesebwa okukola ekiyungu, essowaani oba ekintu ekirala kyonna, obutoffaali bwonna obw’omusaayi busobola okukolebwa okuva mu katoffaali kano aka HSC.
Akatoffaali kano aka HSC kasooka kufuuka katoffaali "akasookerwako". Olwo akatoffaali kano akasookerwako kaawukana ne kaawukana emirundi emirala egiwerako, ku nkomerero ne kafuuka akatoffaali akamyufu, akatoffaali akazungu oba akataffaali akakula mu bujjuvu.
- Okukola obutoffaali obumyufu (Erythropoiesis): Akatoffaali ka HSC kakula ne kafuuka akatoffaali akasookerwako akayitibwa ``erythroblast'', okukkakkana nga kafuuse akatoffaali akamyufu.
- Okukola obutoffaali obweru (Leukopoiesis): Wano waliwo amakubo abiri agakola obutoffaali. Obutoffaali obumu obweru bukolebwa nga buyita mu kkubo lya ``myeloid cell line``, ate lymphocytes nga buyita mu kkubo lya ``lymphoid cell line``.
- Okukola platelets (Thrombopoiesis): Akatoffaali ka HSC kakula ne kafuuka akatoffaali akanene akayitibwa ``megakaryocyte.'' Olwo, platelets zikolebwa nga zimenyekamenyeka mu bitundutundu okuva mu katoffaali kano akanene.
Watya singa wabaawo ekizibu mu nkola eno?
Emibiri gyaffe mulungi nnyo mu kufuga okukola obutoffaali buno obw’omusaayi. Ekyo kitegeeza nti tukola obungi bw’obutoffaali bwokka bwe twetaaga. Naye endwadde ezimu ziyinza okutabula enkola eno. Olwo oba obutoffaali bw’omusaayi butono nnyo, oba bungi nnyo busobola okukolebwa. Tewali n’ekimu ku bino ekirungi eri omubiri.
| Ekika ky’obutoffaali bw’omusaayi | Singa omuwendo gw’obutoffaali gukendeera (Too Few) . | Singa omuwendo gw’obutoffaali gweyongera (Too Many) . |
|---|---|---|
| Obutoffaali obumyufu | Embeera eno eyitibwa anemia . Omubiri guwulira nga gukooye era nga munafu kubanga obutoffaali bw’omubiri tebufuna mukka gwa mukka gwa oxygen gwe gwetaaga. | Embeera eno eyitibwa Erythrocytosis . Kiyinza okuvaako omusaayi okugonza, ne kyongera emikisa gy’okufuna embeera ng’okulwala omutima oba okusannyalala. |
| Obutoffaali obweru obw’omusaayi | Embeera eno eyitibwa Leukopenia . Obutoffaali obweru bwe buba butono, abaserikale b’omubiri banafuwa, era yinfekisoni ziyinza okubaawo emirundi mingi. | Embeera eno eyitibwa Leukocytosis . Ebiseera ebisinga kibaawo ng’olwanyisa yinfekisoni. Naye era kiyinza okubaawo mu ndwadde ezimu ez’omusaayi oba embeera za kookolo. |
| Ebiwuka ebiyitibwa platelets | Embeera eno eyitibwa Thrombocytopenia . N’obuvune obutono busobola okuvaamu omusaayi ogutajja kukoma. Ebiwundu nabyo bisobola okubaawo ku mubiri. | Embeera eno eyitibwa thrombocytosis , era eyongera ku bulabe bw’okuzimba omusaayi okw’akabi okutondebwa munda mu misuwa. |
Embeera ki ezitaataaganya enkola y’okukola omusaayi?
Enkola eno ey’okukola omusaayi esobola okutaataaganyizibwa olw’ensonga ezitali zimu.
- Okukaddiwa: Bwe tukaddiwa, amasavu agali mu busimu bw’amagumba gasobola okweyongera, ekikendeeza ku busobozi bw’okukola obutoffaali bw’omusaayi.
- Endwadde z’omusaayi ne kookolo: Kookolo nga leukemia, lymphoma, ne myeloma asobola okuvaako obutoffaali bw’omusaayi obungi obutali bwa bulijjo okutondebwawo obutakola bulungi.
- Eddagala erimu: Ng’ekyokulabirako, eddagala eriweweeza ku kookolo te liyinza kutta butoffaali bwa kookolo bwokka wabula n’obutoffaali obulamu. Kino kiva ku ddagala erimu.
Bw’oba olina obubonero ng’okuwulira ng’okooye buli kiseera, okufuna omusujja n’okukwatibwa yinfekisoni enfunda eziwera, okunyiga awatali nsonga, oba okuvaamu omusaayi olw’ekiwundu ekitwala ekiseera ekiwanvu okukoma, kakasa nti oyogera n’omusawo wo. Bino biyinza okuba obubonero obulaga nti alina ekizibu ky’omusaayi.
Okukola omusaayi (hematopoiesis) nkola ya bulijjo, eyeetaagisa ennyo okusobola okuwangaala. Akakolero kano akatono akali munda mu magumba gaffe ge gatukuuma nga tuli balamu bulungi era nga tuli ba maanyi. Eno y’ensonga lwaki kikulu nnyo okufaayo ku bulamu bw’omusaayi gwaffe.
Obubaka Obutwala Awaka
- Okukola omusaayi (Hematopoiesis).Kitegeeza enkola omubiri gwaffe gye gukolamu obutoffaali obuyitibwa red blood cells, white blood cells, ne platelets.
- Enkola eno esinga kubeera mu busimu bw’amagumba obuli munda mu magumba gaffe.
- Obutoffaali obumyufu butambuza omukka gwa oxygen, obutoffaali obweru butukuuma obutakwatibwa bulwadde, era obutoffaali obuyitibwa platelets bulekera awo okuvaamu omusaayi nga tufunye ebisago.
- Omuwendo gw’obutoffaali bw’omusaayi obutono oba obusinga ku bwa bulijjo kiyinza okuvaako embeera ez’enjawulo ez’obujjanjabi.
- Bw’ofuna obubonero ng’obukoowu obuyitiridde obutannyonnyolwa, okukwatibwa yinfekisoni enfunda eziwera, oba okuvaamu omusaayi mu ngeri etaali ya bulijjo, kikulu okulaba amangu omusawo akuwe amagezi.
