Omusawo akuwandiikidde eddagala lya ‘Antimetabolite’ oba omuntu akuli ku lusegere okujjanjaba embeera ya kookolo? Bwe kiba bwe kityo, oyinza okwagala okumanya buli kimu ekikwata ku ddagala ery’ekika kino, ebirungi n’ebibi byalyo, n’engeri gye likola. Antimetabolites ye kiraasi y’eddagala erikozesebwa mu kujjanjaba kookolo okutta kookolo. Mu butuufu, ddagala lya kika kya ddagala nnyo erikozesebwa ennyo mu kujjanjaba kookolo, nga likozesebwa okuva mu myaka gya 1940.
Ebirungo bino ebiziyiza okukyusakyusa ebiriisa bye biruwa? Zikola zitya?
Mu ngeri ennyangu, antimetabolites kika kya ddagala erisaanyaawo obutoffaali (cytotoxic) . Ekikolwa kyabwe kibeera kya magezi nnyo.
Teebereza, akatoffaali mu mubiri gwaffe, naddala akatoffaali ka kookolo, keetaaga ebimu ku ‘birungo’ byabwo okusobola okukula, okugabanyaamu, n’okukula. Eddagala lino kye likola kwe kukola nga ‘ekirungo ekicupuli’ ekifaanana ddala ebirungo ebyo. Kale obutoffaali bwa kookolo bulimbibwa era mu kifo ky’ebirungo ebituufu bye bwetaaga okukula, bumira ebirungo bino eby’ebicupuli, eddagala lyaffe.
Amawulire agakwata ku buzaale bw’akatoffaali, kwe kugamba, pulaani enzijuvu ey’akatoffaali ako, gali mu bintu ebiyitibwa DNA ne RNA . Eddagala lino eritta omubiri bwe liyingira mu katoffaali ka kookolo, akatoffaali ako tekasobola kukola kkopi za DNA yaako. Kiba ng’okuteeka kkatiriji enkyamu mu ppirinta n’etesobola kukola kkopi.
DNA bw’eba tesobola kukoppololwa, akatoffaali ako tekasobola kweyawulamu butoffaali bupya. Obutoffaali bwa kookolo bulekera awo okweyongera ne bufa.
Olw’okuba eddagala ery’ekika kino ligenderera nnyo obutoffaali obugabanya amangu , likola nnyo mu kufuga kookolo akula amangu.
Wansi waliwo ebimu ku bikozesebwa mu kujjanjaba kookolo.
| Ebimu ku bikozesebwa ennyo mu kuziyiza metabolisma |
|---|
| 6-ekirungo kya mercaptopurine |
| Eddagala lya Fludarabine |
| 5-ekirungo kya fluorouracil |
| Eddagala lya Gemcitabine |
| Ekirungo kya Cytarabine |
| Eddagala lya Pemetrexed |
| Eddagala lya Methotrexate |
Eddagala lino likozesebwa ku bika ki ebya kookolo?
Antimetabolites zisinga kukozesebwa kujjanjaba kookolo w'omusaayi nga leukemia , kookolo w'amabeere , kookolo w'enkwaso , ne kookolo w'enkola y'ekyenda .
Naye olw’okuba eddagala lino lisobola okuziyiza okukula kw’ekika ky’obutoffaali kyonna ekyeyawukana amangu, abasawo era liriteesa ku bika bya kookolo ebirala eby’enjawulo.
Eddagala lino ngufuna ntya?
Engeri eddagala eriziyiza omubiri gye liweebwamu eyinza okwawukana okusinziira ku ddagala eryogerwako n’ekika kya kookolo ajjanjabibwa.
- Empeke oba amazzi: Ebirungo ebimu ebiziyiza obuwuka obuleeta endwadde bibaawo ng’empeke oba amazzi agasobola okumira mu kamwa buli lunaku.
- Intravenous (IV): Waliwo ebika ebirala eby’empiso eziweebwa mu musuwa. Bino bitera okuweebwa nga saline solution okuyita mu musuwa. Ku bantu abali ku bujjanjabi obw’ekiseera ekiwanvu, eddagala lino oluusi liweebwa nga bayita mu ttanka ey’enjawulo (mediport) eteekebwa mu musuwa omunene, ogw’omu makkati.
- Ebizigo: Ebirungo ebiziyiza omubiri okukola kookolo w’olususu nabyo bifunibwa ng’ebizigo ebiteekebwa ku mubiri. Zino zisiigibwa mu kitundu ky’olususu olukoseddwa omulundi gumu oba ebiri olunaku.
Migaso ki n’akabi akali mu bujjanjabi buno?
Ekirungi ekisinga obunene mu ddagala ery’ekika kino kwe kusaanyaawo obutoffaali bwa kookolo, liyimiriza okukula kwa kookolo oba okumukendeeza. Kino kiyamba omulwadde okudda engulu n’okuwangaaza obulamu bwe.
Kyokka, waliwo akabi akazingirwamu. Eddagala lino terikola kye kimu ku buli muntu. Oluusi, n’abasawo bafuna obuzibu okumanya kookolo ddala eddagala lino lye lisaanira.
Ekirala ekikulu kiri nti oluusi wadde nga mu kusooka kikola bulungi, ekiseera bwe kigenda kiyitawo, obutoffaali bwa kookolo bumanyiira eddagala lino. Kino tukiyita ‘ekiziyiza’. Olwo eddagala lino terikyayinza kukola.
Biki ebiva mu ddagala eriweweeza ku mubiri?
Olw’okuba antimetabolites kiraasi ya ddagala, so si ddagala limu, ebizibu ebivaamu biyinza okwawukana. N’olwekyo, bw’oba owandiikiddwa eddagala eriweweeza ku mubiri, kikulu okwogera n’omusawo wo ku bizibu ebitongole ebikwatagana nalyo.
Naye okutwaliza awamu, waliwo ebizibu ebiwerako ebitera okulabika ku ddagala erisinga obungi eriziyiza omubiri.

Obubaka Obutwala Awaka
- Antimetabolites kika kya ddagala lya ddagala eririmba obutoffaali bwa kookolo okukula ne libulemesa okukikola.
- Zino zisinga kukozesebwa ku kookolo akula amangu nga kookolo w’omusaayi, amabeere, enkwaso, ne kookolo w’olubuto olunene.
- Wadde obujjanjabi buno bulina enkizo ey’okusaanyaawo obutoffaali bwa kookolo, era buba n’obulabe ng’okuziyiza eddagala n’ebizibu ebivaamu.
- Olw’okuba ebizibu ebivaamu byawukana okusinziira ku ddagala, kyetaagisa okumanya eddagala ly’omira n’ebivaamu.
- Ekisinga obukulu: Yogerako n’omusawo wo awatali kulonzalonza ku ddagala lye bakuwadde, ebizibu ebivaamu, n’ebibuuzo byonna oba ebikweraliikiriza by’oyinza okuba nabyo. Ye yekka asobola okukuwa amagezi agasinga obutuufu era agasaanira.
