Lub ntsiab physiological cuam tshuam ntawm progesterone:
1. Progesterone tuaj yeem tswj tus poj niam tsiaj cev xeeb tub, thiab ua rau muaj kev hloov pauv ntawm lub cev, xws li inhibition ntawm poj niam estrus.
2. Progesterone muaj lub zog los txhawb cov thickening ntawm lub tsev menyuam hauv ob sab phlu, txhawb kev khoov ntawm lub caj pas thiab ua kom lub zais zis muaj nuj nqi.
3. Progesterone tuaj yeem cuam tshuam lub peristalsis ntawm lub tsev menyuam, thiab pab txhawb lub tsev menyuam hauv plab, tso pa tawm ntawm cov hnoos qeev, thiab lwm yam. fetus.
4. Me me ntawm progesterone kuj tseem siv nrog cov tshuaj estrogen los txhawb poj niam estrus.Kev sib koom ua ke ntawm progesterone thiab prolactin tuaj yeem txhawb kev loj hlob ntawm cov qog mammary.
5. Progesterone koom nrog hauv kev tawm tswv yim kev tswj hwm ntawm hypothalamus thiab anterior pituitary, uas ua rau kev sib npaug ntawm cov tsiaj cov tshuaj hormones.Hauv vivo, cov ntsiab lus ntawm progesterone ntawm txhua hom tsiaj txhu theem follicular yog qis dua 1 ng / ml, thaum lub sijhawm bovine corpus luteum yog kwv yees li 4 ng / ml, lub sijhawm cev xeeb tub yog li 18 ng / ml.
6. Yav tas los kev tshawb fawb biochemical qhia tau hais tias progesterone modulates kev ua raws li progestogens, kho mob rau kev kho mob ntawm kev rho menyuam, dysmenorrhea, amenorrhea thiab lwm yam tsos mob.Ib qho ntawm progesterone lub luag haujlwm tseem ceeb tshaj plaws yog cov tshuaj hormones, los txhawb thiab tswj cov kev hloov hauv lub tsev menyuam thaum ntxov ntawm cev xeeb tub, siv rau kev rho menyuam tawm, kev coj khaub ncaws tsis zoo, thiab lwm yam. , uas yog siv nyob rau hauv kev kho mob ntawm hem rho menyuam.
Progesterone yog siv los ua cov tshuaj tiv thaiv, rau amenorrhea, rau premenopausal syndrome, infertility, cev xeeb tub tsis tiav, thiab anovulatory uterine los ntshav.
Steroid hormone tsim los ntawm corpus luteum.Induces maturation thiab secretory kev ua ntawm uterine endothelium;suppresses ovulation.Progesterone muaj feem cuam tshuam rau hauv etiology ntawm mob qog noj ntshav mis.Cov tshuaj no yog cov kab mob sib kis ntawm kev txhawj xeeb tshwm sim (CECs).
