Dhuuxa lafta - gacan

Badalida ee dhuuxa lafta, mabda ', waa hawl caafimaad oo cusub - laakiin waxa ay si guul ah loo isticmaali karaa in lagu daaweeyo cudurrada hore loo arkaa mid aan bogsan karin. Tan iyo beerista ugu horeysay ee guul dhuuxa lafta ee 1968, habka this ayaa codsatay daaweynta leukaemia (kansarka dhiigga), dhiig aplastic, lymphoma, multiple myeloma, xanuunada difaac halis ah, iyo xitaa qaar ka mid ah kansarka (kansarka naasaha ama kansarka ugxan sidaha).

Bukaan-socodka transplanted ee loo yaqaan unugyada asliga hematopoietic helay caafimaad dhuuxa lafta aadanaha - unugyada hematopoietic gaar ah oo ku yaalla, waxa ay noqonaysaa, in lafihii lafaha. Waxaa la og yahay in inta badan dhuuxa lafta waxaa ku jira sternum, ee miskaha iyo dhabarta. Badalida unugyada asliga hematopoietic waxaa sabab u ah xaqiiqada ah in unugyada "waxaa ka hormarey" dhammaan unugyada dhiigga iyo habka difaaca ee jirka aadanaha. Xitaa haddii xubin ka bukaanka qadar yar oo ah unugyada asliga hematopoietic, waxay weli awoodi doonaan in ay si buuxda u soo celin habka of hematopoiesis iyo nidaamka difaaca jirka.

Lafta dhuuxa - hab oo loo isticmaali karo in lagu daweeyo kansarka sida qaadasho aad u sarreeya wakiilada gaar ahaan kiimikada, iyo, mararka qaarkood, shucaaca radioactive. Waxaa la og yahay in daaweyn this si joogto ah ay tahay iyo si fiican baabbi'iyaa dhuuxa lafta of bukaanka ah, oo sidaas daraaddeed, in mabda, ma suurtowdo, tan iyo jidhka lumiyo awoodda in ay soo saaraan unugyada dhiigga cas muhiim ah. Si kastaba ha ahaatee, haddii daawaynta ee jirka bukaanka in ay galaan dhuuxa lafta ah oo caafimaad qaba ka dib, waa arrin macquul ah in la bedelo dhuuxa lafta iyo soo celinta awoodda jirka bukaanka ee formation dhiig. In xidhiidh la leh this, lafta dhuuxa by therapy sare-u ogolaan in lagu daaweeyo kansarka markii qaadasho yar yahay waa waxtar lahayn, waxa sabab u yahay dhuuxa lafta.

Waqtigan xaadirka ah, waxaa jira laba nooc oo tallaalid dhuuxa: autologous iyo allogeneic. Marka allogeneic badalida isticmaalaya dhuuxa lafta of qof kale, halka autologous - isaga u gaar ah. Muhiimad ahaan, xubin badalida autologous ma aha, dhab ahaantii, "xubin" dareenka dhabta ah ee eraygan, iyo in tiro ka mid ah ilaha la odhan karaa waa "taageeraya dhuuxa lafaha."

Hawsha ka hor ka saarida ee dhuuxa lafta, waa in la helo waxa ku jira unugyada hematopoietic. Diyaarinta dhuuxa lafta bilaabmaa dhuuxa lafta ka deeq ah oo deedka ku, taas oo, ka hor bilowga daaweynta degdegga ah, laga saaro lafta bidig ee deeq, ku alla kii waxaa laga yaabaa, waa la xayiray iyo keydiyo ilaa isticmaalka. Markaas, marka la dhameystiro chemotherapy ama radiotherapy weheliso, ama sameeyaa iyada oo aan dhuuxa lafta waxaa dib jirka ah ee loo yaqaan "habka faleebo" soo bandhigay. Tani waxay la mid tahay in dhiig lagugu shubo. Transplanted dhuuxa lafta si dhiiga wareegtaa jidhka, ka dibna shubo ee godadka ka mid ah lafahayga, halkaas oo ay ku bilaabmaa kobaca xiga oo, muddo dheer, geeddi-socodka of hematopoiesis waa lay soo celiyey.

Haddii bukaanka uu ahaa nasiib, wax walba si fiican u tegey oo qabsaday maskaxda, bukaanka, siday u kala horreeyaan, kabsaday. Laakiin ma aha oo dhan si farxad ahaato! Bukaanka waa ku hanjabay by laba arrimood. Marka hore, waxaa had iyo jeer waa suurtagalnimada of diidmada jidhka talaalayo. Iyada oo ay taasi aad awoodi karto, nidaamka difaaca ee daawooyin awood badan. The arrin halis labaad waa xaqiiqada ah in 2-3 bilood postoperative bukaanka dhab tagay oo aan habdhiska difaaca jirka. Waxay noqon kartaa halis ah xitaa cudurka ugu yar, taas oo ah sababta, sida ay yidhaahdaan, si looga fogaado, bukaanka waxaa la dhigayaa qaybta gaar ah tallaabooyin ilaalin gaar ah, halka uu ku go'doonsan dunida dibadda u soo kabashada muddada dhan postoperative. Si kastaba ha ahaatee, xitaa ka dib markii la sii daayo isbitaalka u baahan tahay in la si dhow u ilaaliya caafimaadka bukaan-socodka, iyo wuxuu, markeeda, waa in aad aragto dhakhtarkaaga si joogto ah loo sameeyo baadhitaan. dib-socda-tallaalidda caadiga ah difaaca qaadataa hal sano ah, laakiin la sii daraysa ee gobolka bukaan-socodka ee caafimaadka waxaa laga yaabaa in loo baahan yahay sare u rehospitalization.
