Emboozi ekwata ku butoffaali bwaffe: Ka tuyige ku kukebera kwa Flow Cytometry mu ngeri ennyangu!

Wali owuliddeko ku kukebera okuyitibwa Flow Cytometry? Mpozzi omusawo wo akubuulidde ku kukebera kuno. Oba olyawo nga kipya gyoli. Wabula, kigezo kikulu nnyo ekituyamba okuzuula amawulire mangi agakwata ku butoffaali obuli mu mubiri gwaffe. Leero, tugenda kukyogerako mu ngeri ennyangu gy’osobola okutegeera.

Flow Cytometry kye ki?

Mu ngeri ennyangu, flow cytometry kigezo kya laboratory ekikozesebwa okuzuula ebikwata ku butoffaali oba obutundutundu obutono mu mibiri gyaffe. Kilowoozeeko ng’akambega akatono akatunula munda mu kasenge kaffe.

Kino okukikola, sooka kusaanuusibwa sampuli y’obutoffaali bwo (obuyinza okuba omusaayi, obusigo bw’amagumba oba ebitundu ebirala) mu mazzi. Oluvannyuma, omukugu mu laabu ayongerako langi ez’enjawulo eziyitibwa fluorescent antibody dyes mu butoffaali. Ddayimu zino zitegeera era ne zeekwata ku puloteyina ezenjawulo eziri ku butoffaali oba munda mu butoffaali. Mu ngeri endala, zissa akapande akatono oba ‘tag,’ ku puloteyina ezo. Enkola eno oluusi eyitibwa Fluorescence-Activated Cell Sorting (FACS) .

Olwo obutoffaali buno obutegekeddwa ne buteekebwa mu kyuma ekiyitibwa flow cytometer. Ekyewuunyisa, kompyuta eyungibwa ku kyuma kino esobola okwekenneenya obutoffaali nga 10,000 mu ddakiika ntono! Ekyo si kya mangu nnyo?

Kale, okugezesebwa kuno kukozesebwa ki?

Abasawo bakozesa okukebera kuno okwa flow cytometry ku bintu bingi. Okusinga:

• Okubala obutoffaali: Manya ddala obutoffaali bumeka mu sampuli.
• Okusunsula obutoffaali: Okwawula n’okuzuula ebika by’obutoffaali eby’enjawulo.
• Okuzuula engeri y’obutoffaali n’enkola yaayo: Manya ebintu ng’enkula y’obutoffaali n’engeri gye kakola.
• Okuzuula n’okujjanjaba kookolo w’omusaayi n’amagumba: Kino kikulu nnyo okuzuula endwadde nga leukemia ne lymphoma.
• Okuzuula ebiraga obulamu: Bino bye bipimo ebisobola okulagula engeri kookolo gy’agenda okweyisaamu n’engeri gy’anaakwatamu obujjanjabi.
• Immunophenotyping: Okugabanya n’okuzuula ddala ebika by’obutoffaali bw’abaserikale b’omubiri eby’enjawulo bye biri mu mubiri gwaffe.

Okukebera obutoffaali obutambula (flow cytometry test) kukolebwa ddi?

Abasawo bakozesa okukebera kuno okufuna amawulire ag’obuziba agakwata ku butoffaali obuli munda mu mibiri gyaffe. Okusingira ddala:

• Manya ebikwata ku butoffaali bw’abaserikale b’omubiri: Laba obutoffaali obulwanyisa endwadde bwe tulina mu mibiri gyaffe n’ebika ki.
• Laba obutoffaali bwa kookolo era otegeere obutonde bwabwo: Manya engeri obutoffaali bwa kookolo gye bwawukana ku butoffaali obulala n’engeri zaabwo.
• Noonyereza ku mbeera z’obujjanjabi enzibu:
• Kookolo w’omusaayi: Okugeza endwadde nga leukemia ne lymphoma.
• Ebizibu ebirala eby’omusaayi: Okugeza, embeera nga paroxysmal nocturnal hemoglobinuria (PNH) n’obutaba na antithrombin.
• Enkola y’abaserikale b’omubiri: Kebera endwadde nga mukenenya (HIV) n’obuzibu bw’abaserikale b’omubiri obusikira.

Ekirala, oluusi oluvannyuma lw’okubala omusaayi gwo mu bujjuvu (CBC) , singa kiba kyetaagisa okumanya ebisingawo okusinziira ku bivuddemu, okukebera kuno okwa flow cytometry kuyinza okukolebwa. Okusingira ddala, singa CBC eraga okweyongera mu kika ky’obutoffaali obuyitibwa lymphocytes, singa wabaawo obutali bwa bulijjo mu kubala obutoffaali obulala, oba singa eraga nti waliwo obutoffaali bw’omusaayi obutakuze, okukebera kuno kuyinza okulagirwa.

Okukebera kuno kukulu nnyo si kuzuula kookolo yekka, wabula n’okujjanjaba kookolo. Ekyo kili:

• Teebereza obusungu bwa kookolo bwe buli.
• Sazaamu oba kookolo ajja kuddamu obujjanjabi obw'enjawulo .
• Kino nakyo kiyamba okuzuula oba kookolo azzeemu oluvannyuma lw’okujjanjabibwa.

Ekyuma kino ekipima obutoffaali obutambula (flow cytometry machine) kikola kitya? Kyewunyisa!

Ekyuma kino ekipima obutoffaali obutambula (flow cytometry machine) kyekennenya eby’obutonde n’eby’obutonde eby’obutoffaali mu bwangu ddala. Kilowoozeeko ng’okutunuulira obutoffaali ng’oyita mu kkamera ekola amangu ennyo. Laba engeri gye kikola:

1. Okuteekateeka sampuli: Okusooka, omukugu mu laabu akwata sampuli y’omusaayi gwo, ebitundu by’omubiri oba obusigo bw’amagumba n’agusaanuusa mu mazzi (agayitibwa `suspension` ). Olwo nga bwe kyayogeddwako emabegako, langi ey’enjawulo eyitibwa `fluorescently tagged antibodies` eyongerwa mu butoffaali. Olwo ekisengejjero ky’obutoffaali ekitegekeddwa kiyingizibwa mu kipima amazzi agakulukuta.

2. Okukwatagana kw’obutoffaali n’ekitangaala kya layisi: Munda mu kyuma, obutoffaali buno busengekeddwa mu lunyiriri lumu, nga bumu oluvannyuma lw’omulala. Teebereza, ng’abaana b’amasomero abasimbye ennyiriri. Olwo, olunyiriri luno olw’obutoffaali luyita mu maaso g’ekitangaala kya layisi, kimu ku kimu. Ekitangaala kya layisi bwe kikuba obutoffaali, ekitangaala kisaasaana, kwe kugamba, ekitangaala ekisaasaanyiziddwa.

3. Okubala n’okusunsula obutoffaali: Flow cytometer ebala obutoffaali n’ebugabanya okusinziira ku ngeri ekitangaala kya layisi gye kisaasaanya ekitangaala nga kikuba obutoffaali. Buli kika kya katoffaali kisaasaanya ekitangaala mu ngeri ya njawulo. Ekyuma kino kikola nga kizuula enjawulo eyo.

4. 4. .Data to computer: Amawulire gonna (data) agakung’aanyizibwa ekyuma mu ngeri eno gasindikibwa mu kompyuta eyungiddwa ku kyo.

5. Okukola lipoota: Kompyuta yeekenneenya data eno n’ekola lipoota, ebiseera ebisinga mu ngeri ya dot oba bar graph .

6. Okwekenenya kw’omusawo w’endwadde: Mu kusembayo, omukugu mu by’endwadde – omukugu mu by’obujjanjabi azuula endwadde – akebera giraafu zino ne data n’agattako ekiwandiiko ekirimu bye yazudde n’ebyo bye yamaliriza mu lipoota y’okukebera.

Kiki kye nnina okukola nga sinnakeberebwa flow cytometry? Waliwo ekintu kyonna eky’okutya?

Emirundi egisinga, okuggyako ng’omusawo akuwadde ebiragiro eby’enjawulo, tewali nteekateeka ya njawulo eyeetaagisa nga tebannaba kukebera kuno okwa flow cytometry.

Omusawo wo ajja kwetaaga sampuli y’omusaayi, ebitundu by’omubiri oba obusigo bw’amagumba okukola okukebera kuno. Sampuli eno ebiseera ebisinga osobola okugitwala mu ofiisi y’omusawo wo ng’ogendayo. Oluvannyuma lw’okuggyibwako sampuli, esindikibwa mu laabu okukeberebwa.

Omusawo w’endwadde bw’amala okukebera okukebera obutoffaali obutambula (flow cytometry test), ajja kwekenneenya ebikwata ku bantu era asindikire lipoota eri omusawo wo eyasaba okukeberebwa.

Ekisinga obukulu kiri nti mu kiseera kino tewali bulabe bumanyiddwa gy’oli okuva mu kukeberebwa kuno okwa flow cytometry. Kale kino tokitya mu ngeri eteetaagisa.

Ebivaamu biba bitya? Batugamba ki?

Ebiseera ebisinga kitwala ennaku ntono okutuuka ku wiiki emu okufuna ebyava mu kukebera flow cytometry, okusinziira ku laabu omusawo gy’akozesa.

Omusawo w’endwadde atunuulira obubonero obuli kungulu ku butoffaali bwo, obuyitibwa antigens .

• Akatoffaali akalamu kalina enkola ya antigenic eya bulijjo esaanira ekika ky’obutoffaali obwo n’omutendera gwabwo ogw’okukula.
• Enkola eno ya njawulo mu katoffaali akatali ka bulijjo . Enkyukakyuka zino ziyinza okulaga nti waliwo obulwadde bwa leukemia, lymphoma oba embeera endala ez’obujjanjabi.

Omusawo wo bw’anaafuna lipoota y’okukebera, ajja kwekenneenya n’obwegendereza ekiwandiiko ky’omusawo w’endwadde, nga kino kibeera mu bufunze ebikwata ku bikwata ku kompyuta bye yeekenneenyeddwa okuva mu kipima amazzi agakulukuta.

Omusawo wo bw’aba ataputa ebyava mu kukebera obutoffaali obutambula, ajja kulowooza ku bubonero bwo, ebyafaayo by’obulamu bwo, n’okukeberebwa kw’omubiri okwakakolebwa . Ajja kukunnyonnyola ebinaavaamu era akunnyonnyole kye bitegeeza. Era ajja kukozesa amawulire gano okusalawo ekiddako.

Endwadde za ngeri ki eziyinza okulaga nti ebivaamu ebitali bya bulijjo?

Singa ebivaamu biba si bya bulijjo, kiyinza okulaga embeera nga:

• Obulwadde bwa leukemia obuyitibwa lymphoblastic leukemia
• Obulwadde bwa leukemia obw’amaanyi (acute myeloid leukemia).
• Obulwadde bwa lymphocytic leukemia obutawona
• Obulwadde bwa myeloma obuyitibwa multiple myeloma
• Non-Hodgkin lymphomas (zino ziyinza okuzingiramu ebika by’obutoffaali bwa B n’obutoffaali bwa T) .

Singa ebyavaamu biba si bya bulijjo, kiki ekiddako?

Omusawo wo ajja kwogera naawe ebyava mu kukebera obutoffaali bw’amazzi (flow cytometry) n’engeri gy’oyinza okukozesaamu obujjanjabi. Lipoota eno ey’okukebera ejja kuyamba omusawo wo okutegeera engeri embeera yo gy’eri ey’obukambwe, oba obujjanjabi obw’enjawulo bukusaanira, n’engeri gye kiyinza okuba nti kookolo wo ajja kuddamu oluvannyuma lw’okujjanjabwa . Amawulire gano gonna ajja kukozesa okukola enteekateeka y’obujjanjabi ekusaanira.

Endwadde ezimu zitwala akaseera okuzizuula. Oyinza okuba nga wagezesebwa nnyo, naye n'okutuusa kati tolina kya kuddamu kituufu, era oyinza okuba nga weebuuza nti, "Watya singa nkola ekigezo ekirala?" Naye nkkiririzaamu, okukebera kuno okwa flow cytometry kuyinza okuwa omusawo wo amawulire mangi ag’omuwendo agakwata ku butoffaali obuli mu mubiri gwo. Tekijja kukoma ku kuyamba kuzuula bulwadde buno, naye era kijja kukuyamba okukola enteekateeka y’obujjanjabi ey’obuntu ng’ekukwatako.

Kale, bintu ki bye twetaaga okujjukira okuva mu bino byonna? (Obubaka Obutwala Awaka)

Okay, ka nfunze ezimu ku nsonga enkulu okuva mu bye twogeddeko:

• Flow cytometry kigezo kya mulembe nnyo ekisoma obutoffaali mu buziba.
• Kino kiyamba okuzuula kookolo w’omusaayi, obuzibu bw’abaserikale b’omubiri, n’endwadde endala eziwerako .
• Ebiseera ebisinga okukebera kuno kuzingiramu okutwala omusaayi, obusigo bw’amagumba oba ebitundu by’omubiri .
