Dab tsi yog lub ntsiab lus ntawm siab chorionic gonadotropin hauv cov neeg laus

Tib neeg chorionic gonadotropin (HCG) yog glycoprotein secreted los ntawm placental trophoblastic hlwb thiab secreted los ntawm thiab - Glycoprotein. Tib neeg chorionic gonadotropin (HCG) - - , Qhov no yog synthesized hauv lub cev. 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. - HCG ntawm - Cov qauv ntawm LH zoo sib xws, tab sis qhov txuas ntxiv ntawm 24 amino acids kawg yog - Tsis muaj nyob hauv LH. Thaum cev xeeb tub, kev ua haujlwm ntawm corpus luteum txo qis heev, thiab qib ntawm corpus luteum txo. Lub caj pas pituitary secretes ntau los xyuas kom meej tias qib ntawm luteum secretion hauv lub cev.
Luteinizing hormone (LH) yog gonadotropin secreted los ntawm pituitary caj pas. Nws feem ntau ua rau cov gonads, ua rau follicular maturation, ntxiv zais ntawm cov tshuaj estrogen, ovulation, thiab tsim thiab tu ntawm corpus luteum. Qhov tseem ceeb ntawm kev kho mob ntawm luteinizing hormone yog tsuas yog los tshawb xyuas qhov ua rau amenorrhea hauv cov poj niam, nrog rau qhov ua rau cov qog ntshav tsis ua haujlwm hauv cov txiv neej, nrog rau kev loj hlob hormone follicular. Nws kuj tseem tuaj yeem txheeb xyuas cov menyuam yaus ua ntej pubertal tias muaj qhov tseeb lossis cuav ua ntej puberty. Lub ncov ntawm luteinizing hormone thaum lub sij hawm cev xeeb tub tuaj yeem kwv yees qhov zes qe menyuam ovulation. Tsis tas li ntawd, nws qib nce siab, uas tuaj yeem pom hauv polycystic zes qe menyuam syndrome, thawj hypogonadism, menopause, thiab lwm yam. Luteinizing hormone kuj tuaj yeem txo qis hauv cov ntshav thaum siv cov tshuaj tiv thaiv kab mob mus ntev thiab kev kho tshuaj hormone hloov. Tsis tas li ntawd, tib neeg chorionic gonadotropin tuaj yeem cuam tshuam cov stimulation ntawm cov nroj tsuag lectins ntawm lymphocytes. Tib neeg chorionic gonadotropin tuaj yeem adsorb rau saum npoo ntawm trophoblastic hlwb kom tiv thaiv embryonic trophoblastic hlwb los ntawm kev tawm tsam los ntawm leej niam lymphocytes. Thiab LH zoo li kev ua haujlwm, uas ua rau lub cev xeeb tub hauv plab zais zais ntawm testosterone thiab txhawb kev sib deev ntawm txiv neej ua ntej fetal pituitary secretion ntawm LH; Nws kuj tseem tuaj yeem txhawb txoj kev loj hlob ntawm gonads, txhawb nqa qhov tseem ceeb ntawm cov qog nqaij hlav hauv nruab nrog cev rau cov txiv neej, thiab ua kom cov txiv neej cov tshuaj hormones (testosterone). Kev kho mob ntawm cov txiv neej cov neeg mob nrog pituitary union tsis xws luag yog qhov tseem ceeb, tsis yog tsuas yog txhawb kev loj hlob ntawm gonadal thiab txiv neej cov tshuaj hormone secretion, tab sis kuj txhawb kev loj hlob ntawm lwm yam kev sib deev yam ntxwv.
