Kuti azindikire khansa, mayeso a magazi amagawidwa kwa opanga mavitamini. Mmodzi mwa iwo ndi khansa ya embryonic antigen, yomwe nthawi zambiri imagwiritsidwa ntchito pozindikira kuti pali zotupa za m'mimba komanso matumbo ambiri, makamaka colorectal carcinoma. Nthawi zambiri, kansalu kameneka kamagwiritsidwa ntchito poyesa khansara ya chiwindi, mawere, mapapo ndi m'mimba.
Kodi khansa-embryonic antigen kapena CEA ndi chiyani?
Kachigawo kameneka kameneka kalikonse kamakhala ndi mapuloteni ndi zakudya, kotero amatanthauza glycoproteins.
REA imatulutsidwa mwachangu ndi ziwalo za dongosolo la zakudya m'kati mwa chitukuko cha intrauterine, chinalinganizidwa kuti chiwonjezerere kuchulukitsa maselo ndikupangitsa kukula kwa fetus. Pamene munthu ali wamkulu, antigen mu ndalama zing'onozing'ono angapangidwe ndi nyama yathanzi, koma kuwonjezeka kwakukulu mu ndondomeko yake, monga lamulo, kumasonyeza kuti zimakhala zotupa mumtunda kapena pang'onopang'ono. Nthawi zina CEA ikuwonjezeka chifukwa cha matenda omwe amatha kupweteka komanso omwe amawotcha thupi.
Ndikoyenera kudziwa kuti khansa ya embryonic antigen imatchedwanso CEA. Kuchepetsa uku kumachokera ku dzina la glycoprotein mu Chingerezi - Carcino Embryonic Antigen.
Chibadwa cha khansa ya embryonic antigen kwa akazi
Makhalidwe abwino kapena oyenerera a CEA amadalira pang'ono pa kukhala ndi zizoloŵezi zoipa.
Choncho, kwa amayi omwe amasuta, chizoloŵezi cha khansa embryonic antigen chimachokera ku 5 mpaka 10 ng / ml ya magazi.
Pogwiritsa ntchito mowa mopitirira muyeso, chiwonetserochi chikuposa 7-10 ng / ml.
Ngati mkazi alibe zizolowezi zoipa, CEA (CEA) yamba imatha kuyambira 0 mpaka 5 ng / ml.
N'chifukwa chiyani antigen ya embryonic antigen ingakwezeke?
Kuwonjezeka kwakukulu kwa zomwe zimafotokozedwa kuti glycoprotein m'magazi amapezeka m'matumbo oopsa a ziwalo zotere:
- utumbo wakuda;
- kachilombo ;
- mapapo;
- mimba;
- mphukira;
- mammary gland.
Kupitiliza kachitidwe ka CEA kawirikawiri kumachitika ndi kubwezeretsedwa kwa mankhwala omwe poyamba analipo, komanso mavitamini ambiri m'matumbo a chifuwa, chiwindi.
Kuonjezerapo, kuwonjezeka kwa chiwerengero cha CEA kungachitike ndi matenda omwe sali otupa:
- ulcerative colitis;
- matenda a chiwindi;
- mapuloteni mu rectum kapena matumbo aakulu;
- chiwindi cha chiwindi;
- chifuwa chachikulu;
- cystic fibrosis;
- kupweteka;
- chitsulo;
- impso kulephera;
- emphysema wa mapapo;
- choyimira;
- Matenda a Crohn ;
- chibayo.
