I-hormone ye-TSH ngexesha lokukhulelwa lizimisele ngokuvavanywa kwegazi kwaye ibaluleke kakhulu ekuhloleni imeko yomama, ukuphuhliswa komntwana kunye nokuba khona kwezilwanyana ezinokwenzeka. I-TTG ikhuthaza umsebenzi ophezulu wegolisi ye-thyroid, ngoko ke emva kwesigaba se-TTG ekukhulelweni ukulawula rhoqo kuyimfuneko.
IHotrotropic hormone
I-TTG yi-hormone ye-lobe yangaphambili ye-pituitary gland. I-Thyrotropin ilawula ukuphuhliswa kunye nokusebenza kwethambo le-thyroid, ngokukodwa ukuveliswa kwe-triiodothyronine (T3) kunye ne-thyroxine (T4), elawula intliziyo kunye nenkqubo yesondo, inxaxheba kwiinkqubo zokuxilongwa, kunye nokuchaphazela imeko yengqondo.
Inkcazo ye-TSH incike kwizinga lamahomoni T3 kunye ne-T4. Ngoko, ngemveliso eqhelekileyo ye-T3 ne-T4, ekhusele i-TSH, umxholo wayo emzimbeni wehla. Iqondo le-hormone lihluka kwi-0.4 ukuya kwi-4.0 mU / L, ngelixa isantya se-TSH kubasetyhini abakhulelweyo banokuhluka ngokwahlukileyo kwiimpawu eziqhelekileyo.
Njengomthetho, isalathisi se-TTG kwabasetyhini abakhulelweyo sincinane kunokuba siqhele, ngokukodwa xa kukho ukukhulelwa okubanzi . Kubalulekile ukuba uqaphele ukuba i-TSH ephantsi iyakubonisa kuphela uvavanyo kunye novelwano oluphezulu, ngaphandle koko i-hormone iya kuba yinto. Ngakolunye uhlangothi isandla seTSH esikhulelweyo ngexesha lokukhulelwa asikho ukuphambuka kwimiqathango.
Inqanaba le-TTG ngexesha lokukhulelwa lihlala liguquka, ngoko-ke imimiselo ye-hormone kunzima ukuyiqonda. Iimpawu eziphantsi kakhulu zigcinwa kwiiveki ezi-10 ukuya kwezi-12, kodwa kwezinye iimeko i-TSH ephantsi iqhubeka iqhubeka ngexesha lokukhulelwa.
I-TTG ingezantsi kwimiqathango yokukhulelwa
Ukuba ngexesha lokukhulelwa i-TTG iyancipha, akukho sizathu sokukhathazeka-njengomthetho, esi sibonakaliso sesiqhelo. Kodwa kwezinye iimeko, i-TSH ephantsi ingabonakalisa uphawu olungalindelekanga:
- ukuphazanyiswa kweengcambu ze-pituitary;
- Isifo sePlummer;
- isisu esinobungozi se-thyroid gland;
- i-postpartum necrosis ye-pituitary gland;
- Umgangatho ophezulu wee-hormone ze-thyroid;
- Umlenze uphephe.
Iimpawu ze-hormone ephantsi i-TSH ekukhulelweni ngaphantsi kwesiqhelo yintloko yesifo, umkhuhlane ophezulu, intliziyo rhoqo. Kananjalo ekunciphiseni kwe-TSH kubonakalisa uxinzelelo lwegazi oluphezulu, isisu esicasulayo, ukuvusa ingqondo.
I-TTG ngasentla isingqinisiso okanye izinga lokukhulelwa
Ukuba uhlalutyo lubonisa ukuba izinga le-TSH ngexesha lokukhulelwa liphezulu kakhulu, oogqirha banikezela iimviwo ezongezelelweyo ezongezelelweyo, kuba isibalo esiphezulu se-hormone singabonisa ezi mpazamo ezilandelayo:
- ukugula ngengqondo;
- ukuphulwa kweentlanzi ze-adrenal;
- ubukho besisu;
- ukuphazanyiswa kweengcambu ze-pituitary;
- gestosis enkulu;
- ukungasebenzi.
Iimpawu zokunyuka kwe-TSH yilezi: ukukhathala, ubuthathaka obuninzi, ukulala, ukungabi naso, ukushisa okuphantsi , ukutya okungafuni ukutya, ukunyusa. Amanqanaba aphakamileyo a-TSH angabonwa ngokunyusa intamo yomfazi okhulelweyo. Njengomthetho, xa i-hormone ephezulu ifunyenwe, abafazi abakhulelweyo bayamiselwa unyango kunye ne-L-thyroxine.
Ukubonisa i-TTG kubalulekile ukukhathalela ngokukodwa,
