Cov thyroid caj pas yog qhov loj tshaj plaws nyob hauv tib neeg lub cev. Tsis muaj ducts rau hauv nws, yog li tag nrho cov tshuaj hormones uas nws tas li ua tau, tam sim ntawd poob rau hauv cov ntshav. Cov thyroid caj pas yog tswj hwm los ntawm hypothalamus thiab pituitary caj pas. Nws nyob hauv lawv tias cov tshuaj hormones uas yuav tsum tau siv rau lub cev ua haujlwm ntawm tag nrho endocrine system raug tsim tawm.
Dab tsi muaj feem xyuam rau cov tshuaj TSH?
TSH (thyrotropic hormone) yog cov tshuaj hormone ntawm cov tib neeg lub hlwb. Nws yog tsim nyob rau hauv lub anterior lobe ntawm pituitary caj pas thiab tswj cov kev ua ntawm cov thyroid caj pas. Thyrotropin ua rau cov neeg nyob hauv lub qog thawv, thiab qhov no ua rau tus lej thiab qhov loj ntawm cov thyroid hlwb. Tab sis qhov no tsis yog txhua yam, rau cov tshuaj hormone TTG sib ntsib. Nws kuj:
- activates adenylate cyclase;
- tsub kom qhov txau ntawm cov thyroid iodine ntawm hlwb;
- nce lub synthesis ntawm proteins, phospholipids thiab nucleic acids.
Tab sis feem ntau cov tseem ceeb, dab tsi cuam tshuam rau cov tshuaj TSG - qhov ntau lawm ntawm cov thyroid hormone T4 thiab biologically active hormone TZ. Nws yog nws leej twg stimulates lawv cov tsos, thiab lawv tseem ceeb heev rau lub cev hauj sim ntawm tag nrho cov kab mob, vim T3 thiab T4 ua xws li kev khiav dej num:
- ua tib zoo xav;
- Ua rau kom lub cev muaj zog thiab ntshav siab;
- tswj cov chaw ua pa;
- nce lub zaus thiab lub zog ntawm kev mob plawv ntawm lub plawv;
- nce kev puas siab puas ntsws;
- hnia lub txiaj ntsim ntawm cov proteins uas tsim los ntawm cov tom qab lub plab;
- accelerate lub nqus ntawm oxygen nyob rau hauv lub plab hnyuv siab raum.
Hormone TSH hauv lub cev
Yog ib qho kev sib raug zoo ntawm qhov ntau ntawm hormones TSH thiab dawb T4. Yog hais tias muaj ntau ntawm thyroxine (T4) hauv cov ntshav, qhov no ua rau ib tug txo qis hauv zus tau ib lub rhiab heev thyroid-stimulating hormone TSH. Raws li, ib tug thawj txo nyob rau hauv T4 concentration tsub kom zus tau cov TSH. Kev hloov ntawm lub cev yuav qhia tau hais tias muaj cov kab mob hauv lub cev thiab ua kom muaj kev paub txog cov kev mob ntsws.
Yog li, yog tias ho hormone TSH muaj qis dua, nws muaj peev xwm txo qhov kev ua haujlwm ntawm lub qog poo thiab cov kev mob hyperthyroidism , thiab TSH TSHIAB tshaj qhov teebmeem vim tsis muaj teebmeem adrenal thiab muaj kev puas hlwb lossis qog mob loj. Kev txo qis ntawm T4 lossis T3 tuaj yeem ua rau:
- qhov tsos ntawm kev mob nkeeg;
- weakening ntawm kev txawj ntse peev xwm;
- txo cov ntshav siab;
- mob hauv plawv ;
- plawv atherosclerosis teebmeem;
- kev puas tsuaj ntawm kev ua me nyuam;
- mob ntawm cov hnyuv.
Cov pojniam cev xeeb tub, txo qis ntawm T3 thiab T4 tuaj yeem cuam tshuam ntawm cov pob txha ntawm tus menyuam thiab cov hlwb ntawm nws lub hauv siab, thiab ua rau cov neeg tsis muaj zog ntawm oxygen thiab ntau cov as-ham hauv cov ntaub so ntswg ntawm lub fetus.
Kev soj ntsuam rau cov tshuaj hormones TTG, T3, T4
Rau kev kuaj ntawm cov thyroid caj pas thiab kev xaiv ntawm kev kho txaus, ib qho kev soj ntsuam ua rau cov tshuaj hormones T4, TTG thiab T3. Tag nrho cov thyroid hormones shchitovidki tuaj yeem nyob rau hauv kev sib txuas los yog xoob xeev, yog li kev kuaj ntshav no tuaj yeem yog:
- T3-tag nrho (dawb triiodothyronine + khi);
- T4-dawb (thyroxine dawb, uas tsis yog txuam nrog cov ntshav proteins);
- T4-dav (dawb thyroxine + khi);
- TZ-dawb (dawb triiodothyronine (T3), uas yog tsis txuam nrog cov ntshav proteins).
Qhov tseem ceeb ntawm cov ntsiab lus ntawm cov thyroid hormone thyrogens TSH, T3 thiab T4 nyob rau hauv cov ntshav yuav muaj kev txawv me ntsis raws li kev kuaj kev siv, hnub nyoog thiab kev sib deev ntawm tus neeg mob.
Nws yog heev yooj yim kom dhau xws li ib qho kev ntsuam xyuas. Nws tsuas yog tsim nyog:
- Nco ntsoov tias thaum lub hli tas los koj tsis noj tshuaj uas cuam tshuam rau cov thyroid ua haujlwm.
- Tsis txhob noj 10-12 teev ua ntej qhov kev kuaj ntawd.
- Tsis txhob haus luam yeeb lossis haus dej haus cawv, thiab txo qoj ib ce rau hnub ua ntej kev kawm.
