I-hormone prolactin ibhekwa njengama-hormone wesifazane wesifazane. Indima yayo yemvelo ayikwazi ukugxila kakhulu: i-prolactin inomthelela omkhulu noma omncane phakathi nezinqubo ezingaba ngu-300 ezihlukene emzimbeni wesifazane.
I-hormone prolactin nokujwayelekile kwayo kwabesifazane
Iyini isimiso seprolactin kwabesifazane? Ayikho impendulo ecacile yalo mbuzo, ngoba izikhungo ezahlukene ze-laboratory, ngenxa yezindlela ezihlukahlukene zokucwaninga, ama-reagents ahlukene abeka amanani awo (reference). Ngaphezu kwalokho, ama-laboratories ahlukene asebenzisa amayunithi ahlukene weprolactin.
Izinkomba ezilinganiselwe ezingeni elijwayelekile le-prolactin kwabesifazane zingasenqunywa. Ngakho-ke, umkhawulo ophansi wezinga leprolactin owesifazane onempilo nonokukhulelwa akumele udlulele esimeni sika 4.0-4.5 ng / ml. Okwamanje, njengoba umkhawulo ongaphezulu kufanele ube ngaphansi kuka 23.0-33.0 ng / ml.
Ngesikhathi sokuya esikhathini, izinga leprolactin kumuntu wesifazane lishintsha, ngokulandelana, futhi amazinga e-hormone ngezigaba ezahlukene zomjikelezo ahlukile. Odokotela batusa ukwenza ukuhlolwa kwegazi ekuqaleni komjikelezo wokuya esikhathini (ngesikhathi sesigaba se-follicular). Kodwa uma kwenzeka ngesizathu esithile ekuqaleni komjikelezo wesimiso isifundo asizange senziwe, i-laboratory ngayinye isungula imigomo yayo ngezigaba ezalandela.
I-prolactin iyi-hormone "ebucayi" kakhulu, izinga layo lingashintsha ekucindezelekeni okuncane kakhulu, ukushisa, emva kokulala ngokocansi, ngokumelene nesizinda sokuthatha imithi ethile, futhi ngaleyo ndlela kuphazamise imiphumela yocwaningo. Ngenxa yalesi sizathu, uma kuqhathaniswa nokuthembeka okuthe xaxa kwesibonakaliso esitholakalayo sezinga le-hormone prolactin kanye nesimiso sayo kumuntu wesifazane oneminyaka yobudala, kuhlaziywa ukuhlaziya kabili.
Ukungahambi kahle kwe-prolactin: izimbangela ezikhona
Isimo, lapho izinga le-prolactin engowesifazane liwela ngaphansi kwesimiso, ngokuvamile aludingi ukwelashwa. I-prolactin ingancipha ngendlela ephawulekayo ngenxa yokuthatha imithi ethile, ikakhulukazi, izidakamizwa, inhloso yayo ekuqaleni ukunciphisa ukukhiqizwa kwe-hormone efanayo.
Ucwaningo olwengeziwe lokuqinisekisa / ukukhipha izifo ze-pituitary kuyadingeka kuphela uma izinga lamanye ama-hormone e-pituitary ehla ngaphansi kwezinga elivamile ne-prolactin.
Ukwedlulisa ukuhlushwa okuvamile kwendlala ye-hormone prolactin kowesifazane kungabangela izinqubo zemvelo emzimbeni wakhe
- (ukukhulelwa, isikhathi sokuncelisa ingane), futhi kungabonisa ukuba khona kwamathambo agciwane, njengoku:
- i-tumor ye-pituitary gland (prolactinoma);
- ukungasebenzi komzimba we-thyroid (hypothyroidism);
- i-polycystic i-ovary syndrome (i-PCOS);
- isifo esibi kakhulu nesifo sezinso;
- izicubu ze-hypothalamus.
Ngokuvamile owesifazane akaqageli ukuthi izinga le prolactin emzimbeni wakhe landa, kuze kube yisikhathi lapho engeke abhekane nenkinga yokukhulelwa kwengane. I-prolactin ephakeme iyimbangela yokungasebenzi komuntu owesifazane wesihlanu owake wezwa ukuxilongwa okunjalo.
Izinga elivamile le-prolactin kubesifazane abakhulelwe
Izinga leprolactin kwabesifazane abakhulelwe lihlale liphakanyisiwe, lokhu kuyinto evamile. Ukuxilongwa kwe-hormone egazini kuvela kakade ngeviki lesishiyagalombili lokukhulelwa futhi kufinyelele esiphezulu nge-trimester yesithathu. Ukugxila kwe-prolactin kunciphisa kancane kancane futhi kubuyele emazingeni ayo okuqala kuphela ngemva kokuphela kokuncelisa.
Ngokwezimiso ezisungulwe, izinga leprolactin kubantu besifazane abakhulelwe kufanele libe ngaphansi kuka 34-386 ng / ml (ngokusho kwamanye ama-laboratories 23.5-470 ng / mg), okwandisa kancane kancane ngesikhathi sokukhulelwa kusukela emngceleni ophansi kuya phezulu. Kodwa odokotela abathile banamuhla bathi akukho nhlobo ekusekeni noma yiziphi izinqubo zeprolactin kwabesifazane abakhulelwe.
Isizinda se-hormonal sowesifazane ngamunye okhulelwe singumuntu ngamunye kangangokuthi ukushintshashintsha kwe-hormonal ehlukahlukene, kuhlanganise nokukhipha kwe-prolactin, kaningi akuhambisani nanoma yimiphi imigomo, noma kunjalo, leli qiniso aliyona i-pathology.
