Ukuze uthole umdlavuza, ukuhlolwa kwegazi okunomsoco kunikezwa abaqaphi. Enye yazo i-antigen-embryonic antigen, evame ukusetshenziswa lapho kutholakala khona izicubu zezintuthwane ezinkulu namathumbu, ikakhulukazi i-colorectal carcinoma. Ezimweni ezingavamile, lesi sigqebhezana somdlavuza sisetshenziselwa ukuhlola ukuthuthukiswa komdlavuza wesibindi, isifuba, amaphaphu nesisu.
Yini i-antigen-embryonic antigen noma i-CEA?
Ukwakhiwa kwamakhemikhali we-composite okukhulunywa ngayo kuhlanganisa amaprotheni nama-carbohydrate, ngakho-ke kubhekisela kuma-glycoprotein.
I-REA ikhiqizwa ngenkuthalo yizingxenye zesimiso sokugaya ukudla ngesikhathi sokuthuthukiswa kwe-intrauterine, yenzelwe ukuvuselela ukubuyabuyelela kweseli futhi ivuselele ukukhula komntwana. Lapho umuntu esekhulile, i-antigen emalini amancane kakhulu angakhiqizwa yenyama enempilo, kodwa ukwanda okuphawulekayo ekugxilweni kwayo, njengombuso, kubonisa izinqubo ze-tumor ekoloni noma emgqeni. Ngezinye izikhathi i-CEA ikhuphuka ngenxa yokuqhubeka kwezifo ezizimele nezivuzayo zezingaphakathi zangaphakathi.
Kufanele kuqaphele ukuthi i-antigen yomdlavuza obizwa ngokuthi i-cancer-embryonic isacaciswa ngokuthi i-CEA. Lokhu kuncipha kuvela egameni le-glycoprotein ngesiNgisi - i-Carcino Embryonic Antigen.
Norm we-anti-cancer embryonic abesifazane
Izithenjwa noma izindinganiso ezijwayelekile zokubeka i-CEA zixhomeke kancane ekufikeni kwemikhuba emibi.
Ngakho-ke, kulabo abashaya umusi, isimiso somdlavuza embryonic antigen sisuka ku-5 ukuya ku-10 ng / ml wegazi.
Ngokusebenzisa kabi utshwala, lesi sibonakaliso sikhulu kakhulu - 7-10 ng / ml.
Uma owesifazane engenayo imikhuba emibi, inani elijwayelekile le-CEA (CEA) lingabuka ku-0 ukuya ku-5 ng / ml.
Kungani i-antigen emangcwabeni yama-embryon ephakeme ingakhuphuka?
Ukunyuka okuphawulekayo ekugxileni kwe-glycoprotein egazini kubonakala ezinhlakeni ezimbi zezingxenye ezinjalo:
- amathumbu aminyene;
- i-rectum ;
- amaphaphu;
- isisu;
- i-pancreas;
- i-mammary gland.
Ukwedlulela esimisweni se-CEA ngezikhathi eziningi kwenzeka ngokuphindaphindiwe kokuthola ukwelashwa kwezinto eziphilayo, kanye nama-metastases amaningi emathanjeni amathambo, isibindi.
Ngaphezu kwalokho, ukwanda kwenani le-CEA kungenzeka ngezifo ezingekho izifo:
- i-ulcerative colitis;
- i-hepatitis engapheli;
- i-polyps e-rectum noma emathunjini amakhulu;
- i-cirrhosis yesibindi;
- isifo sofuba;
- i-cystic fibrosis;
- i-pancreatitis;
- i-bronchitis;
- ukuhluleka kwezinso;
- emphysema yamaphaphu;
- i-autoimmune pathologies;
- Isifo sikaCrohn ;
- i-pneumonia.
