Tsimbisa kana kuti kuramba kuwedzera kwechirwere chinotyisa mumutsara wezvokudya, pamwe nekuongorora kushanda kwekurapa kunobvumira mumwe munhu anonzi REA. Iyi glycoprotein inobudiswawo nevanhu vakuru vane utano, asi mune zvishoma. Nekubudirira kwekenza, iyi puroteni-carbohydrate compound inodarika iyo yakagadzirirwa muganhu.
Chii chinonzi CEA kana CEA chinomirira?
Zvakakosha kuziva kuti zvose izvi zvinyorwa izvi zvinoreva glycoprotein imwe chete. Icho chete chirevo CEA chinowanikwa kubva kuChirungu Carcinoembryonic Antigen (carcinoembryonic antigen), uye CEA inotaridzwa sekenza-embryonic antigen. Munguva yeprauterine kukura kwe fetus, iyo inenge ichitaridzirwa inonyatsobudiswa nhengo dzechipfuva chemuviri, zvinodiwa kusimudzira nekusimbisa kubereka kwemasero. Chinangwa chekuda kwechidiki ichi chekuwedzera kune vanhu vakuru hachina kusimbiswa.
Chii chinonzi ECA incomarker show?
Iyo yakatsanangurwa glycoprotein inotsanangurira chinangwa chekuongorora zvimwe zvipembenene zvinotyisa, kazhinji zviputi zvemukoko uye mumatumbo makuru.
Kunyange zvakadaro, chirwere chekenza CEA kana kenza-embryonic antigen haigoni kuonekwa sechinhu chakatendeseka chaiyo, sezvo inongororwa inogona kuwedzera kunyange mune zvisiri zvemaitiro zvevanhu. Semuenzaniso, CEA inowedzera munyaya yekufambira mberi kwezvinyorwa zvekudzivirira uye kuvhiringidza mukati memitezo.
Kazhinji, CEA kuongororwa inorayirirwa kutanga kwekusiyanisa kwekenza yekoloni kana kenza yemukomana, sezvo chiyero ichi chinonyanya kunzwisisika kune idzi zvinopisa zvinopisa. Mukuwedzera, chidzidzo chinogona kushandiswa sehumwe husimbiso hwemakumbo mumudumbu, mapapu, mukaka uye pancreas, prostate, mazai, uyewo kuvapo kwemasastases mumapfupa uye chiropa.
Oncologists anowanzokurudzira kupiwa ropa nguva dzose kumushandi wekenza weACE kana murwere ari kutotanga kurapwa kana ave achivhiyiwa kubvisa tumarara. Mumamiriro ezvinhu akadaro, kuongororwa kweprotheni-carbohydrate compound kucharatidza kuti nzira yakasarudzwa yekurapa yakange yakagadziriswa sei, zvisinei kuti kudzokororazve kwechirwere kunogona kuitika.
Norm of onomarker REA
Mumunhu ane utano, huwandu hweGlycoprotein CEA haufaniri kudarika 3.8-4 ng / ml ropa. Mugumisiro wekuongororwa, uri mukati memiganhu iyi, unoratidza pangozi yakadzika yekudzidzira chirwere chekenza.
Panguva imwecheteyo, kuedzwa kweEEC hakuiti kune dzimwe mvere dzinenge dziri kunze kwebhuku remimba.
Sei chikwata che CEA chinogona kukurudzirwa?
Iko kuwedzerwa kuwanda kweprotheni-carbohydrate muzana REA inowanikwa mune zviputi zvinotyisa zvenhengo dzakadaro:
- rectum;
- hutumbu hukuru;
- dumbu;
- mammary gland;
- mapapu;
- pancreas;
- metastases muropa uye pfupa.
Kunewo zvikonzero zvisingaiti zvekuwedzera kweEECA:
- ulcerative colitis;
- chronic hepatitis;
- tuberculosis;
- pancreatitis;
- bronchitis;
- chirwere chechiropa;
- cystic fibrosis;
- mapuropa mumutsara kana mumatumbo makuru;
- Chirwere cheCrohn;
- pneumonia;
- autoimmune pathologies;
- emphysema yemapapu ;
- renal insufficiency.
Uyezve, kuwedzera kuduku mumusana wekenza embryonic antigen inowanikwa mukusvuta. Kwavari, kunyange mararamiro emuitiro we CEA akashandurwa kubva pa3 kusvika ku5,5 ng / ml. Zviratidzo zvakafanana zvinoshandiswa kune avo vanoshungurudza zvakasimba zvinwiwa zvinodhaka zvinodhakwa nemishonga.
