Tiyeni tingophunzira za mayeso a immunophenotyping omwe amathandiza kuzindikira maselo a khansa.

Mwina simunamvepo za mawu akuti `(Immunophenotyping)` kale. Koma iyi ndi mayeso ofunikira kwambiri, makamaka pozindikira matenda ena, mwachitsanzo, khansa ya m'magazi, khansa ya m'magazi, ndi khansa zina. Chifukwa chake, lero tikambirana za mayesowa m'njira yosavuta, kuti mumvetsetse bwino.

Kodi Immunophenotyping ndi chiyani? Tiyeni timvetse mosavuta.

Chabwino, tsopano tiyeni tiwone tanthauzo la mawu akuti `(Immunophenotyping)`. Ngakhale kuti izi zikumveka ngati mawu asayansi, nkhaniyi ndi yosavuta kwenikweni.

Mawu oti 'Immuno' amatanthauza chinthu chokhudzana ndi chitetezo chathu chamthupi. Mu mayesowa, katswiri wa matenda (dokotala yemwe ndi katswiri pa matenda) amagwiritsa ntchito mtundu wina wa puloteni wotchedwa 'antibodies' kuchokera ku chitetezo chathu chamthupi kuti afufuze mapuloteni enaake otchedwa 'antigens' m'maselo athu. Ganizirani za 'antibodies' awa ngati kiyi, ndi 'antigens' ngati loko. Monga loko yomwe imakwanira kiyi iliyonse, 'antibody' yeniyeni imangogwirizana ndi 'antigen' yeniyeni. Mwa kuyankhula kwina, pali mtundu wa awiri ofanana pakati pa awiriwa.

Mawu akuti 'phenotype' amatanthauza makhalidwe omwe amawonekera kunja . Chifukwa chake, pamene '(antibody)` imeneyo igwirizana ndi '(antigen)` yofunikira, katswiri wa matenda amadziwa ngati selo limenelo lili ndi '(antigen)` imeneyo kapena ayi kutengera zizindikiro zomwe zimasonyeza.

Mwachidule, mayeso a `(Immunophenotyping)` awa amayang'ana zizindikiro za `(antigens)` izi pamwamba pa maselo athu ndikupeza ngati maselo amenewo ndi athanzi kapena maselo a khansa. Komanso, `(antigens)` awa amatha kudziwa mtundu wa selo la khansa.

Kodi mayeso awa (Immunophenotyping) amachitidwa liti?

Pali zochitika zingapo zomwe dokotala wanu angakulimbikitseni mayeso awa.

Tangoganizani kuti mnzanu, tiyeni tinene kuti Nimal, wakhala akutopa kwambiri komanso wotopa kwa masiku angapo. Dokotala atamuyesa magazi (a ``Complete Blood Count'', kapena ``CBC''), adapeza kuti kuchuluka kwa maselo oyera m'magazi mwake kunali kokwera kwambiri. Kenako dokotalayo angaganize kuti mwina ndi khansa ya m'magazi. Pamenepo angakulangizeni kuchita mayeso a ``Immunophenotyping'' kuti mudziwe zambiri za zomwe zikuchitika.

Izi zikutanthauza:

• Ngati zotsatira za kuwerengera magazi kwathunthu (`(CBC)`) zikusonyeza kuti kuchuluka kwa maselo oyera m'magazi anu kuli kokwera kwambiri.
• Ngati pali kukayikira kwa mitundu ina ya khansa ya m'magazi, monga khansa ya m'magazi kapena lymphoma, izi zingathandize kuyandikira pang'ono matendawo.

Kuphatikiza apo, ofufuza akugwiritsanso ntchito njira iyi ya ``Immunophenotyping'' kuti aphunzire momwe maselo a khansa amayankhira ku zizindikiro zinazake za ``antigen'', makamaka ``immunotherapy''.

Kodi mayesowa amagwira ntchito bwanji?

Mayeso ambiri a `(Immunophenotyping)` amachitika mu labu, mukatenga minofu kapena madzi kuchokera kwa inu. Kunena zoona, chomwe muyenera kuchita ndikupereka chitsanzocho, ndipo akatswiri mu labu amachita zina zonse.

Madokotala ambiri amagwiritsa ntchito njira ya labu yotchedwa ``Flow Cytometry'' pochita mayesowa. Kuphatikiza apo, nthawi zina njira yotchedwa ``Immunohistochemistry - IHC'' imagwiritsidwanso ntchito. Tiyeni tiwone zonsezi.

Pali njira ziwiri zazikulu ...

(Njira ya Flow Cytometry) (njira yomwe imagwiritsidwa ntchito kwambiri)

Pogwiritsa ntchito njira iyi, mutha kuwona zitsanzo zazikulu za magazi kapena maselo amagazi otengedwa kuchokera ku minofu. Umu ndi momwe imagwirira ntchito:

• Kusonkhanitsa chitsanzo: Izi nthawi zambiri zimaphatikizapo kutenga chitsanzo cha mafuta a m'mafupa kuchokera ku biopsy ya mafuta a m'mafupa, kapena magazi ochepa. Nthawi zina, chitsanzocho chingatengedwe kuchokera ku madzi a msana kapena madzi a m'mimba.
• Kusunga chitsanzo: Ogwira ntchito mu labu amakonzekera chitsanzocho kuti chiyesedwe cha ``Immunophenotyping''. Amawonjezera zinthu zina kuti maselo asafe.
• Kuwonjezera (Antibody): Kenako, amawonjezera ``antibodies`` zomwe adapanga kuti zimangirire ku ``antigen`` yomwe akufuna kupeza. ``antibodies`` izi zimalumikizidwa ku ``fluorescent compound``` kapena ``immunofluorescence marker``. Chifukwa cha chizindikiro ichi, ``antibody``` ikalumikizana ndi ``antigen``, maselo amatulutsa kuwala.
• Kuchita (Flow Cytometry): Tsopano chitsanzo chokonzedwa ndi `(ma antibodies)` amenewo chimayikidwa mu makina otchedwa `(Flow Cytometer)`. Makinawa ali ndi masensa apadera (`zowunikira`), omwe amatha kuzindikira kuwala komwe kumachokera ku `(chizindikiro cha immunofluorescence)`. Chifukwa chake, `(Flow Cytometer)` iyi imayesa kuchuluka kwa maselo omwe ali ndi `(antigen-antibody)` (kutanthauza kutulutsa kuwala).

(Njira ya Immunohistochemistry - IHC)

Immunohistochemistry ndi njira yomwe ingathe kuzindikira kupezeka kwa ma antigen enaake mu chitsanzo cha minofu. Njira zomwe zimachitika mu labu ndizofanana kwambiri ndi zomwe zimachitika mu flow cytometry. Kusiyana kwakukulu ndikuti mu IHC, enzyme imawonjezeredwa ku ma antibodies m'malo mwa compound ya fluorescent. Enzyme iyi imadetsa maselo ndi mtundu winawake ngati antigen ilipo. Ngati katswiri wa matenda awona banga pansi pa maikulosikopu, zikutanthauza kuti maselowo ali ndi antigen.

Kodi mayeso awa (Immunophenotyping) ali ndi zofooka zotani?

Vuto lalikulu ndilakuti si labu iliyonse yomwe imachita mayesowa yomwe ili ndi " njira zokhazikika." Chifukwa chake, nthawi zina pamakhala kusiyana pang'ono pazotsatira.

Koma chinthu chimodzi chomwe muyenera kukumbukiraMadokotala sapeza matenda kutengera zotsatira za `(Immunophenotyping)` zokha. Amawayerekeza ndi zinthu zina zambiri, monga zizindikiro zanu ndi zotsatira za mayeso ena, kuti apeze yankho. Izi zikutanthauza kuti mayeso okhawo sakukuuzani kuti muli ndi khansa. Ndi chithunzi chimodzi chokha, ndi gwero limodzi lokha lomwe lingakuthandizeni kudziwa zambiri za thanzi lanu.

Kodi zotsatira zake zimakhala bwanji? Kodi zikutiuza chiyani?

Dokotala wanu adzakufotokozerani tanthauzo la zotsatira zanu kutengera kusanthula kwa katswiri wa matenda. Zotsatira za mayeso a ``Immunophenotyping'' sizikhala ``zabwino'' kapena ``zoipa'' zokha. Zimatengera katswiri wodziwa bwino za matenda kuti amvetse ``deta'' yopangidwa ndi ``Flow Cytometer'' yokhudza chitsanzocho ndikutanthauzira molondola zomwe chikunena.

Kuchokera pa izi, iye akusanthula zinthu monga:

• Kodi 'mtundu wa maselo oyera a magazi' ndi chiyani?
• Kodi ali pa siteji iti ya chitukuko?
• Kodi mukufuna maselo angati omwe ali ndi antigen?

Katswiri wa matenda amayerekeza deta yochokera mu chitsanzo chanu ndi deta yochokera kwa anthu athanzi omwe alibe khansa, komanso deta yochokera kwa anthu omwe ali ndi mtundu winawake wa khansa ya m'magazi kapena lymphoma. Pogwiritsa ntchito njira izi ndi zotsatira za mayeso ena, iye amatsimikiza momwe mungakhalire ndi khansa yomwe ikukambidwa.

Kodi ndiyenera kuyimbira dokotala wanga liti?

Ngati muli ndi mafunso kapena nkhawa zokhudzana ndi zotsatira zanu kapena tanthauzo lake, onetsetsani kuti mwayimbirani dokotala wanu . Immunophenotyping ndi mayeso ovuta a labu omwe amayang'ana mawonekedwe a maselo. Koma dokotala wanu akhoza kufotokoza momwe zimakhudzira thanzi lanu mwachidule.

Mwina simunamve ululu uliwonse, ndipo munadabwa kupeza kuti maselo anu oyera anali okwera kwambiri pa mayeso a magazi achizolowezi ("CBC"). Kapena mwina mwakhala mukudwala kwa kanthawi. Komabe, zotsatira za "CBC" zimenezo ndi gawo loyamba loti mudziwe zomwe zikuchitika, kotero muyenera kukhala oleza mtima.

Maselo anu ali ndi zambiri zofunika zokhudza thanzi lanu. Kuyeza kwa Immunophenotyping ndi mayeso omwe amayang'ana maselo anu ndikukuuzani za thanzi lanu. Nthawi ngati izi, kudikira zotsatira kungakhale koopsa komanso koyambitsa nkhawa. Ngati mukufuna thandizo la maganizo, lankhulani ndi dokotala wanu za izi. Komanso, ngati muli ndi mafunso okhudza zotsatira za mayeso, musazengereze kufunsa.

Zinthu zofunika kwambiri zomwe tiyenera kuphunzira kuchokera pa izi

Chabwino, tiyeni tifotokoze mwachidule zinthu zofunika kwambiri zomwe tiyenera kukumbukira pa mayeso a `(Immunophenotyping)` omwe takambirana lero.

• Iyi ndi mayeso apadera a labu. Amathandiza kwambiri kupeza matenda a khansa monga khansa ya m'magazi ndi khansa ya m'magazi.
• Izi zimachitika pozindikira mapuloteni apadera otchedwa ``antigens'' pamwamba pa maselo athu.
• Njira ziwiri zomwe zimagwiritsidwa ntchito kwambiri ndi ``Flow cytometry'' ndi ``Immunohistochemistry - IHC''.
• Zotsatira zake zimakhala zovuta pang'ono, kotero katswiri wa matenda amawafufuza.
• Kumbukirani izi: Palibe amene angakuuzeni kuti muli ndi khansa pongoyang'ana zotsatira za mayesowa. Ndi gawo limodzi lokha la njira yodziwira matenda.
• Ngati muli ndi mafunso okhudza zotsatira zake, musaope kufunsa dokotala wanu. Iwo alipo kuti akuthandizeni.
