Kuti uone kenza, kuongororwa ropa kunowanikwa kune vanowedzera. Imwe yadzo ndeye kenza-embryonic antigen, iyo inowanzoshandiswa pakuongorora zvirwere zve rectum uye mumatumbo makuru, kunyanya colorectal carcinoma. Muzviitiko zvisingawanzoitiki, chirwere chekenza ichi chinoshandiswa kuita chiedza chekuvandudzwa kwekenza yeropa, mazamu, mapapu uye mudumbu.
Chii chinonzi cancer-embryonic antigen kana CEA?
Icho chimiro chemakemikari iri mubvunzo iri mubvunzo rinosanganisira mapuroteni nemahydrohydrates, naizvozvo inoreva glycoproteins.
REA inoshingaira kubudiswa nhengo dzekudya kwekudya mukati mekugadzirisa intrauterine, yakagadzirirwa kuita kuti kuwedzerwa kwema cell uye kukurudzira kuwedzera kwekuberekwa. Mukukura, antigen mune zviduku zvishoma zvinogona kubudiswa nehupenyu huri nani, asi kuwedzera kukuru muhutano hwayo, sekutonga, kunoratidza hutachiona hutsika mumakoroni kana kuti rectum. Dzimwe nguva CEA inowedzera nekuda kwekuwedzera kwezvirwere zvinoputika uye zvinoputika zvemuviri.
Zvakakosha kuziva kuti kenza-embryonic antigen ichiri kunzi CEA. Iri kuderedza kunobva kune zita re glycoprotein muchiChirungu - Carcino Embryonic Antigen.
Norm yekenza-embryonic antigen kuvakadzi
Iyo inotaurwa kana kuti yakarongeka mitemo ye CEA inotarisa zvishoma pane kuvapo kwemitemo yakaipa.
Nokudaro, kune vakadzi vanosvuta, chimiro chekenza embryonic antigen chinobva kune 5 kusvika 10 ng / ml yeropa.
Nekushandisa doro zvisina kunaka, chiratidzo ichi chinonyanya kukura - 7-10 ng / ml.
Kana mukadzi asina tsika dzakaipa, iyo yakakwana ye CEA (CEA) inogona kubva kubva ku 0 kusvika ku 5 ng / ml.
Nei chirwere chekrisyria chinonzi antigrionic chinogona kukwidziridzwa?
Kuwedzera kwakanyanya mumakamuri ezvakatsanangurwa glycoprotein muropa inowanikwa mumatumbu anorwadza ezvikamu zvakadaro:
- utumbo hwakakomba;
- rectum ;
- mapapu;
- dumbu;
- pancreas;
- the mammary gland
Kuwedzera kwemaitiro eEEC muzviitiko zvinowanzoitika nekudzokazve kwekare kwaive nekugadzirwa kwehutano hwehutano, pamwe chete nemasitasita akawanda mu bone bone, chiropa.
Mukuwedzera, kuwedzera kwenhamba ye CEA kunogona kuitika nehosha dzisiri dzomuviri:
- ulcerative colitis;
- chronic hepatitis;
- mapuropa mumutsara kana mumatumbo makuru;
- chirwere chechiropa;
- tuberculosis;
- cystic fibrosis;
- pancreatitis;
- bronchitis;
- kidney failure;
- emphysema yemapapu;
- autoimmune pathologies;
- Chirwere cheCrohn ;
- pneumonia.
