Iprolactin ikhiqizwa yi-pituitary gland yamadoda kunye nabasetyhini. Kodwa nawuphi na ubudala kumadoda asemgangathweni, kwaye kwabasetyhini baya kuba nokunyuka, kuxhomekeke kwiminyaka kunye nesigaba somjikelezo wesini. Kubantwana, i-prolactin iphantsi, kwaye ukunyuka kwayo kuqala kumantombazana ngexesha lokukhulelwa.
Kwakhona, ukwanda kwe-hormone prolactin kubasetyhini kugcinwe ngokomzimba ngexesha lokukhulelwa kunye nexesha lokuncelisa. Inokuphakanyiswa kwabasetyhini emva kokulala ngokwesini okanye ukuvuselelwa kweengono, emva kokuxinezeleka okukhulu, kwaye ngelo xesha akukhuthazwa ukuba udlule uvavanyo lweprolactin . Iprolactin kunye nezinga layo egazini lichaphazela ama-hormone wesini esetyhini, ngakumbi ukungalingani kwe-hormone. Kwaye emva kokumiselwa kwexesha, inqanaba leprolactin lingancipha.
Isiqhelo seprolactin kubasetyhini
Kwabesifazane abangabaliyo ngexesha lokuzala, inqanaba leprolactin lisuka kwi-4 ukuya kuma-23 ng / ml, kwaye ekukhulelweni kwinqanaba liphakama ukusuka kwi-34 ukuya ku-386 ng / ml.
Izizathu zokunyuka kweprolactin
Ukwandisa izinga leprolactin lingaba ngenxa yezifo ze-hypothalamus (izibilini, isifo sofuba), izifo zesifo (prolactinoma). Kodwa inani lezifo zombini kunye nezinye izitho kunye neenkqubo zingakhokelela ukwanda kwinqanaba leprolactin.
Inqanaba leprolactin liphuma ngezifo ezifana nama-ovari, njenge- polycystic .
Inqanaba eliphezulu leprolactin liya kwenzeka xa:
- hypothyroidism;
- ukuhambisa i-goiter enobuhlungu;
- lupus erythematosus;
- i-anorexia;
- i-cirrhosis yesibindi;
- i-rheumatoid arthritis;
- ukungaphumeleli kwindlala;
- kunye nokulimala kwesifuba.
Izizathu zokuncipha kweprolactin
Inqanaba leprolactin egazini lingawela kwezinye izicubu ezinobungozi zesifo se-pituitary okanye isifo sofuba, emva koxinzelelo olunzima lwe-craniocerrebral, ukwehla kwinqanaba leprolactin kunokwenzeka emva kokusetyenziswa ixesha elide kweziyobisi ezinokunciphisa izinga.
