Njani yingozi iphakamileyo hCG ngexa lokukhulelwa?

Pregnancy zingangqinwa uhlalutyo igazi okanye umchamo ubukho chorionic gonadotropin kwabantu. Le hormone lukhutshwe blastocyst (aqhamileyo iqanda kwinqanaba elilandelayo division) emva umzila kwi wesibeleko kunye villi ngumkhaya. hormone mngeni ukugcina imveliso yellow imizimba dlala ovarian, nto leyo efunekayo ukuze uphuhliso olungekazalwa. Simele sikhumbule ukuba xa ephezulu i hCG ukukhulelwa ukuze abonise ezinye ukungaqheleki xa Palsy. Madoda, kwakunye phambi hCG egazini abasetyhini abakhulelweyo isenokubonisa umhlaza wamatyhalarha okanye umhlaza ovarian kunye nezinye iintlobo zomhlaza.

Ngokuqhelekileyo, gonadotropin amanqanaba igazi ngezantsi 5 mu / ml sijongwa ezimbi, ngamanye akukho ukukhulelwa. Isiphumo ngaphezu 25 mIU / ml kucingwa HIV kwaye uthi umfazi ekhulelwe. Ukususela umzila bemveku zingenzeka ngamaxesha ahlukeneyo emva ovulation (kweentsuku ezilishumi kwi-avareji), ngoko ekukhuleni hCG Pregnancy liqala kwiintsuku nje ezimbalwa emva kokukhulelwa.

Umbungu, leyo ezinambuzelayo ityhubhu Imibhobho kulo isibeleko, equlathe node osandul (iseli clusters), kunye ezingqongileyo umaleko, eyaziwa ngokuba trophoblast. Nantso ke apho iqala khona imveliso kunye secretion of gonadotropin, ofikelela zamaqanda, apho kukhuthaza elisandul 'ukusekwa corpus luteum ukuvelisa yiprogesterone.

Chorionic hormone gonadotropin kungabonwa yi igazi nomchamo uvavanyo. Uvavanyo zegazi zinokuxela ubukho hCG ngokuchanileyo ukufumana mali ka emzimbeni. Olu vavanyo ingasetyenziswa ukuqinisekisa ukuba umfazi ekhulelwe, ekukhuleni komntwana, okanye imigangatho ephakamileyo hCG na enabela eqhelekileyo ezinxulumene nomhlaza. Inqanaba chorionic gonadotropin kwabantu hormone udla kuthathelwa ingqalelo xa ukuhlolwa bekhubazekile. Olu vavanyo yenziwa phakathi kwiveki 15 20 yokukhulelwa. Ukongeza igazi nomchamo iimvavanyo kwenziwa. Olu vavanyo ayinikeli umlinganiselo echanekileyo kumanqanaba hCG, kodwa ke ibonisa ubukho kunokwenzeka hormone. Uhlalutyo umchamo kufuneka iqokelelwe ngoko nangoko emva wake-up, kuba kwinxalenye yokuqala ka inqanaba hCG siphezulu.

Xa ukukhulelwa kwangethuba, hCG lisezantsi kakhulu, kwaye kuphela sicatshulwa leentsuku, eyavela uya kabini malunga zonke 48 iiyure yaye ifikelela iphezulu iiveki 7-12, emva koko kancinane kuya kuncipha. Uyondelelwano lwee- hCG kufuneka ikhule kabini yonke kwiveki yesithathu yokukhulelwa. Xa ixabiso ifikelela 1200-6000 mIU / ml, ukukhula kuya kwenzeka qho kwiiyure ezingama-96. Kakhulu hCG aphezulu abasetyhini abakhulelweyo esinxulunyaniswa kunye ngezifo yethishyu placental, okanye ukubonisa okuvela choriocarcinoma. Ukongeza, hCG ephakamileyo ukukhulelwa isenokuba kuba sisiphumo ukhulelwe. Kwakhona, ukwanda ezingaqhelekanga kumanqanaba gonadotropin nga kwenzeka kwimeko pregnancy, ukukhubazeka ukuzalwa komntwana okanye kwezisu.

Loo hCG ephakamileyo ukukhulelwa iliphawu ukukhulelwa izinyo. Ngenxa impazamo yemfuza, emva kokukhulelwa, ukukhula okungaqhelekanga eziseleni uqalisa ukwakha amaqamza kwi ngumkhaya. Nangona umfazi unokuba iimpawu eqhelekileyo yokukhulelwa, loo ukungaqheleki chromosomal kuyingozi kakhulu kuba nako ukuphuhlisa kwifomu wolusu.

Kufuneka kukhunjulwe ukuba hCG ophakamileyo ngexesha ukhulelwe kunokubangela isicaphucaphu nokugabha. Ngelishwa, le umyalezo akukaqondwa kakuhle. Kodwa ke uninzi amanqanaba ezingaqhelekanga of hCG lwenzeka khona abafazi ngaphantsi 20 kwama-35 eminyaka.

Kakade ke, akukho mfuneko yokuba ukuthelekisa inqanaba hCG kwabasetyhini ezahlukeneyo akhulelweyo ngokulinganayo. Ayithandi inokuba nomahluko kakhulu, ukutshintsha ngaphezulu kobomi le ephethe usana, kwaye baxhomekeke kwimpilo yokuphila yomfazi. Okona kubalulekileyo, xa hCG ukho kule ndawo kuluhlu eqhelekileyo kwandisa phezu iiveki.
