Human chorionic gonadotropin yog ib yam tshuaj los ntawm pawg glycoproteins, uas qhia qhov pib ntawm cev xeeb tub hauv poj niam lub cev. Nws yog qhov zoo li nyob rau hauv cov zis ntawm chorionic gonadotropin nyob rau hauv cev xeeb tub thiab piav txog cov tsos ntawm ob lub strips ntawm kev xeem. Taug qab kev ntseeg ntawm kev loj hlob ntawm chorionic gonadotropin thaum cev xeeb tub, nws yog ib qho ua tau kom txiav txim siab tias kev xeeb tub li cas.
Chorionic gonadotropin thaum cev xeeb tub yog dab tsi
Feem ntau, cov txiv neej thiab cov poj niam uas tsis xeeb tub, qhov kev ntsuam xyuas β-hCG ntawm 0-5 mU / ml. Qib ntawm chorionic gonadotropin pib nce hauv thawj hnub tom qab implantation ntawm lub embryo rau hauv lub uterine kab noj hniav. Nws yog tsim los ntawm cov ntaub so ntswg ntawm chorion thiab plays lub luag haujlwm tseem ceeb hauv kev coj ua thaum cev xeeb tub. Yog li, tib neeg chorionic gonadotropin txhawb nqa lub tsho me nyuam, thiab kuj txhawb qhov kev lag luam ntawm lub cev daj (ntau lawm ntawm hormone progesterone ). Tom qab lub tsho me nyuam hauv plab lawm, nws yuav siv sij hawm rau qhov kev ua ntawm synthesizing tus chorionic gonadotropin.
Thaum pib ntawm cev xeeb tub, txhua txhua ob rau peb hnub, qhov taw qhia ntawm h-hchch (tib neeg chorionic gonadotropin) doubled. Pib txij li lub 10-11th lub lim tiam ntawm cev xeeb tub, cov kev loj hlob hauv hCG yig qeeb, raws li lub tsho me nyuam yuav luag tsim thiab pib noj cov tshuaj hormones ntawm cev xeeb tub. Yog li, hauv thawj lub lim tiam ntawm cev xeeb tub, tus nqi ntawm chorionic gonadotropin nyob rau hauv cov ntshav yog nyob rau hauv ntau ntawm 25-156 mU / ml. Cov qib chorionic ntawm 1000 g / m tau sib raug rau lub as thiv thib 3 ntawm cev xeeb tub. Ntawm 4-5 lub lis piam no daim duab no yog 2560-82300 mU / ml, thaum 7-11 lub lis piam tom qab qhov kev xav ntawm chorionic gonadotropin nyob rau hauv cov ntshav nce mus txog 20900-291000 mU / ml, thiab thaum 11-12 lub as thiv nws tau txo rau 6140-103000 mU / ml.
Chorionic gonadotropin muaj ob lub subunits - alpha thiab beta. Lub sub alpha yog zoo tib yam hauv kev nrog cov thyroid-stimulating, luteinizing thiab follicle-stimulating hormones. Cov beta subunit yog qhov tshwj xeeb hauv nws cov qauv.
Gonadotropin chorionic - siv
Gonadotropin tib neeg chorionic yog siv los kho tshuaj ntxiv (stimulation ntawm ovulation nrog nyob rau hauv vitro fertilization, txij nkawm ntawm kev ua hauj lwm ntawm lub cev daj). Chorionic gonadotropin rau cov txiv neej tau raug tsom mus rau kev hnoos qaum cov tshuaj tua kabmob thiab cov tshuaj cog qoob loo (qee zaum siv cov kev ua si li doping).
Kev siv chorionic gonadotropin yog qhia hauv cov pathologies nram no:
- nyob rau hauv cov poj niam uas tsis muaj luteal theem (kom hnia ovulation thiab tswj cov kev loj hlob ntawm lub cev daj);
- nyob rau hauv cov txiv neej nrog underdevelopment ntawm testicles, qeeb tau puberty, hypogonadotropic hypogonadism.
Cov tshuaj gonadotropin chorionic yog contraindicated thaum:
- qog ntawm cov qog kev sib daj sib deev, zoo li lwm tus ua los ntawm kev ua txhaum ntawm cov gonads;
- cryptorchidism tshwm sim los ntawm femoral hernia, raug mob thiab phais;
- tus tib neeg tsis kam ua rau tus chorionic gonadotropin.
Yuav ua li cas prick ib tug chorionic gonadotropin?
- Cov tshuaj chorionic gonadotropin yog muaj raws li kev txhaj tshuaj. Cov tshuaj Intramuscular ntawm cov gonadotropin zoo zoo thiab raug ua raws li tus kws kho mob cov tshuaj.
- Ntawm cov kev mob tshwm sim tuaj yeem txhim kho cov ntshav siab thiab txhaws taus cov teeb meem ntawm cov ntshav, nrog rau lub plab me nyuam ntawm kev sib daj sib deev. Cov tub hluas tuaj yeem ntiav lawv cov qog cov qog, lawv tuaj yeem tsim o thiab pob txuv.
Peb kuaj lub luag haujlwm ntawm chorionic gonadotropin nyob rau hauv lub cev ntawm ib tug poj niam cev xeeb tub, thiab kuj tau txais kev paub nrog kev siv nws cov synthetic analogues.
