I-prolactin ikhiqizwa yi-pituitary gland yamadoda nabesifazane. Kodwa kunoma yikuphi ubudala emadodeni izinga lawo lihlala njalo, futhi kulaba besifazane kuyoba khona ukushintshashintsha, kuye ngokuthi ubudala kanye nesigaba sokujikeleza kokuya esikhathini. Ezinganeni, i-prolactin iphansi, futhi ukwanda kwayo kuqala kumantombazane ngesikhathi sokukhulelwa.
Futhi, ukwanda kwe-hormone prolactin kwabesifazane kuhlonishwa ngokomzimba ngesikhathi sokukhulelwa nangesikhathi sokubeletha. Kungaphakanyiswa kwabesifazane emva kokuya ocansini noma ukugqugquzelwa kwezinsipho, emva kokucindezeleka okukhulu, futhi ngalesi sikhathi akukhuthazwa ukuba kudlule ukuhlolwa kweprolactin . I-prolactin nezinga layo egazini lichaphazela ama-hormone wesifazane wesifazane, ikakhulukazi ukungalingani kwe-hormone. Futhi ngemva kokunqamuka kokuya esikhathini, izinga leprolactin lingancipha kancane.
Umkhuba we-prolactin kwabesifazane
Kulaba besifazane abakhulelwe ngesikhathi sokuzala, izinga leprolactin lihlukanisa kusuka ku-4 kuya ku-23 ng / ml, futhi ekukhulelweni izinga laso liphakama kusuka ku-34 kuya ku-386 ng / ml.
Izimbangela zokwanda kweprolactin
Ukwandisa izinga leprolactin kungase kube ngenxa yezifo ze-hypothalamus (izicubu, isifo sofuba), izifo ze-pituitary (prolactinoma). Kodwa izifo eziningi zomzimba zomzimba kanye nezinye izitho nezinhlelo zingabangela ukwanda kwezinga leprolactin.
Izinga leprolactin liphuma ngezifo ezinjalo zama-ovari, njenge- polycystic .
Izinga eliphezulu le prolactin lizokwenzeka uma:
- i-hypothyroidism;
- isakaza i-goiter enobuhlungu;
- i-systemic lupus erythematosus;
- i-anorexia;
- i-cirrhosis yesibindi;
- i-arthritis ye-rheumatoid;
- ukwehluleka kwezintuthwane ezingapheli;
- kanye nokulimala kwesifuba.
Izimbangela zokunciphisa prolactin
Izinga le prolactin egazini lingase liwele kwezinye izicubu ezibulalayo zesigwegwe se-pituitary noma isifo sofuba, ngemuva kokuhlukunyezwa okukhulu kwe-craniocerebral, ukwehla ezingeni le prolactin kungenzeka ngemuva kokusebenzisa isikhathi eside izidakamizwa ezingase zinciphise izinga layo.
