Dab tsi yog Tus Nqi Li Cas Ntawm Chorionic Gonadotropin

Cov poj niam hauv kev npaj cev xeeb tub feem ntau saib xyuas lawv lub cev zoo. Tom qab cev xeeb tub, lawv cov kev coj khaub ncaws yuav nres. Yog tias cov poj niam hauv kev npaj cev xeeb tub pom tias lawv lub cev xeeb tub tsis tau tshaj tawm rau ob lub lis piam, lawv tuaj yeem siv daim ntawv kuaj cev xeeb tub thaum ntxov rau kev kuaj. Lawv tuaj yeem mus rau hauv tsev kho mob kom kuaj xyuas cov ntsiab lus ntawm chorionic gonadotropin. Tus nqi ib txwm muaj ntawm chorionic gonadotropin yog dab tsi?
Dab tsi yog tus nqi ib txwm muaj ntawm chorionic gonadotropin
Tib neeg chorionic gonadotropin, tseem hu ua HCG, yog ib qho tseem ceeb qhia txog seb tus poj niam cev xeeb tub thiab kev loj hlob thiab kev loj hlob ntawm lub gestational sac. Nyob rau hauv ib txwm muaj xwm txheej, tib neeg chorionic gonadotropin nyob rau hauv cov poj niam zoo tib yam yuav tsum nyob rau hauv qhov ib txwm muaj thiab tsis zoo. Qhov ntau npaum li cas yog nyob ntawm qhov kev siv ntau yam ntawm txhua lub tshuab. Qhov kev siv ntau yam rau cov tshuab feem ntau yog {{0}} txog 5 lossis 0 txog 10. Tsuav nws nyob hauv qhov ntau, nws yog qhov qub, qhia tias tus poj niam tsis xeeb tub.
Tib neeg chorionic gonadotropin (HCG) yog glycoprotein secreted los ntawm trophoblastic hlwb ntawm placenta thiab glycoprotein muaj pes tsawg leeg ntawm lub dimer. Glycoprotein hormone nrog lub cev hnyav ntawm 36700, Cov subunits yog qhov pib zoo ib yam li FSH (follicle stimulating hormone), LH (luteinizing hormone), thiab TSH (thyroid stimulating hormone) secreted los ntawm lub caj pas pituitary, yog li kev sib cuam tshuam tuaj yeem tshwm sim ntawm lawv cov subunits. muaj cov qauv sib txawv. Hauv cov poj niam laus, tom qab lub qe fertilized txav mus rau hauv lub uterine kab noj hniav thiab implanted, nws tsim ib tug embryo. Thaum lub sij hawm tus txheej txheem ntawm kev loj hlob mus rau hauv ib tug fetus, lub syncytiotrophoblast hlwb ntawm lub placenta tsim ib tug loj npaum li cas ntawm HCG, uas yuav raug tso tawm mus rau hauv cov zis los ntawm cov ntshav ncig ntawm tus poj niam cev xeeb tub.
Tib neeg chorionic gonadotropin, lossis ntshav HCG, yog zais los ntawm cov hlwb trophoblastic ntawm placenta thiab yog glycoprotein uas tswj kev xeeb tub. Lub xub ntiag lossis tsis muaj cev xeeb tub tuaj yeem txiav txim siab los ntawm kev tshuaj xyuas tus nqi ntawm tib neeg chorionic gonadotropin. Thaum tsis xeeb tub, tus nqi ntawm tib neeg chorionic gonadotropin yog 0-5, uas pib zais rau hnub thib rau ntawm cev xeeb tub. Txog ntawm 8-10 hnub tom qab cev xeeb tub, qhov nce hauv cov concentration ntawm chorionic gonadotropin tuaj yeem kuaj pom hauv cov ntshav ntawm tus neeg tau txais kev pab.
Tib neeg chorionic gonadotropin thaum lub lim tiam plaub ntawm cev xeeb tub
"Cov ntshav HCG nyob ib ncig ntawm plaub lub lis piam ntawm cev xeeb tub yog txog 10000, uas yog qhov qub." Qhov kev hloov pauv ntawm HCG yog qhov loj heev. HCG hauv cov ntshav tuaj yeem kuaj pom kev txhim kho ntawm embryo thaum cev xeeb tub. Raws li ib txwm muaj, tus nqi ntawm HCG hauv cov ntshav nce ob zaug ib hnub, thaum progesterone maj mam nce, qhia tias lub embryo tab tom loj hlob zoo. "Yog tias qib ntawm HCG hauv cov ntshav tsis tuaj yeem ua tau zoo dua ob npaug, thiab qib ntawm progesterone tsis tuaj yeem ua kom zoo, nws feem ntau cuam tshuam txog kev pheej hmoo rho menyuam."
"Thaum thawj plaub lub lis piam ntawm cev xeeb tub, tus nqi HCG yuav tsum ncav cuag 500-10000 ua ntej nws tuaj yeem suav tias yog ib txwm muaj. Cov txiaj ntsig HCG qis yog qhov ua rau nchuav menyuam. Nyob rau theem pib ntawm cev xeeb tub, cov niam uas muaj menyuam yuav tsum tau saib xyuas ntau dua rau kev noj zaub mov zoo. thiab so ntau dua." HCG nce sai heev hauv cov ntshav thaum thawj peb lub hlis twg ntawm cev xeeb tub, ua ob npaug hauv li 1. ib qib.
3. HCG kuj tseem tuaj yeem kuaj pom seb cev xeeb tub thaum ntxov yog rho menyuam thiab tsis suav nrog cev xeeb tub. Tseem muaj cov laj thawj vim li cas tus nqi HCG siab dhau lossis qis dhau. Yog tias nws tsis nyob hauv qhov qub, cov niam txiv uas muaj kev cia siab yuav tsum tsis txhob txhawj ntau dhau, thiab yuav tsum tau mus rau hauv tsev kho mob sai sai los daws qhov teeb meem. Nco ntsoov: so kom txaus, ntxiv dag zog rau khoom noj khoom haus, thiab xyuam xim rau so.
