TTG. Isiqhelo sezinga lehomoni egazini

Njengamanje, kwindlela yokwelapha, umgangatho ukhula ngokukhawuleza ukufundisisa imisebenzi yeehomoni. Ukusetyenziswa kwonyango lwe-hormone kwinqanaba langoku lenze ukuba kube lula ukulusebenzisa kungekhona nje ukutshintshwa kweyonyango, kodwa kwakhona njengamachiza ahlukeneyo akhuthaza ukuphucula ngokukhawuleza nangokuphumelelayo. Njengamachiza, amalungiselelo ama-hormone asetyenziswa ngokuqhelekileyo kuzo zonke iindawo zemithi, phakathi kwazo zizisebenzisa kakhulu ezi zinyango.

I-hormone ye-thyrotropic inikeza ulawulo kunye nokulawulwa kwe- hormone nge-thyroid gland. Isiqhelo se-TTG kubantwana ngokukhethekileyo sikhethwe ngumdala. Ngaloo ndlela, kwiintsana, iqondo le-hormone lihluka ukusuka ku-1.1 ukuya kwe-17 ngokwemiqathango yamazwe ngamazwe. Kwiqela leminyaka engaphantsi kwama-2.5-3, i-hormone ye-thyroid-stimulation hormone ivela kwi-0.6 ukuya kwi-10. Kubantwana ukuya kunyaka, umda ophezulu uncitshiswe kwiinqununu eziyi-7. Kutheni abantwana abasandul 'ukuzalwa benaloo ndlela ephakamileyo yamahomoni? Oku kubaluleke kakhulu ngenxa yokuba ukuphuhliswa kwenkqubo yesantya yabantwana kudinga izinga eliphezulu lamahomoni e-thyroid. Kwinkqubo yokugqiba ukusekwa kwenkqubo ye-nervous, inqanaba lalo lugqithiso lancipha kancane. Kubalulekile ukulawula izinga lokutshintsha kwe-hormone kubantwana, kuba ukuba i-thyroid ayiyancipha - oku kuya kubonisa i-hypothyroidism engamazalwa. Ukuba akukho nonyango yesi sifo, ukulahlwa kwengqondo kungahlakulela.

Kutheni sifuna esi siqhelo?

Ukwazi amazinga e-hormone aqhelekileyo kuyimfuneko yokuvavanya imeko ye-endocrine yomntu. Ngoko, ukudlula amazinga e-thyroid-stimulating hormone ngokuqhelekileyo ibonisa intsholongwane ye-thyroid gland (hypothyroidism). Ukongezelela, utshintsho kwimvelaphi ye-hormone kwinqanaba lokunyuka lingabonisa ukusilela kweengqungquthela ze-adrenal, izicubu ze-pituitary gland kunye nezifo zengqondo.

Isiqhelo se-TTG ekukhuleleni kuyahluke kwilo qela elidala. Ukuqala kweenguqu zomzimba kumzimba wesetyhini okhulelweyo kubangela ukwanda kwehomoni ye-thyroid. Ukongeza, isiqhelo kubasetyhini sincike kwisigaba somjikelezo wesini. Ukwanda kwinqanaba le-hormone kungabangela ukusetyenziswa kwamalungiselelo athile amayeza, kunye nokusebenza ngokomzimba.

Xa kukho ukwehla kwinqanaba leTTG?

Iqondo eliphantsi le-hormone ye-pituitary linokubangelwa ziinguqu eziqhelekileyo (eziphathekayo) kunye neenkqubo zentsholongwane emzimbeni womntu. Umgangatho we-TTG uyancipha ngendlala, ukunyamezela kwengqondo, kunye nokunyanga kwamayeza e-hormone. Kwimeko yesifo se-pathological, izinga eliphantsi le-hormone ye-thyroid evuselela ingabonakalisa izifo ezifana ne-hyperthyroidism, umsebenzi owenziwe okanye ukuxhwaleka kwi-pituitary gland.

Uvavanyo lwegazi lwama-hormone lwenziwa kwi-laboratory ekhethekileyo. Isampululelo segazi lenziwa kusasa ngesisu esingenalutho. Njengoko sele sele kuchaziwe ngasentla, oku kusemgangathweni kunqunywe ngumbuso osebenzayo wendalo, kunye nokuguqulwa kwamathambo kuwo. Iqondo le-hormone evuselela i-thyroid kumadoda lincinci kunabesifazane, kwaye abantu asebekhulile bancitshiswa ngakumbi ngenxa yokunciphisa umsebenzi wezobugcisa.

Ngaloo ndlela, ixabiso le-hormone ngokubanzi, kunye ne-TTG, ngokukodwa, inkulu kakhulu. Utshintsho kwiimpawu zenza kube lula ukukrokra utshintsho olusenzayo, ukuqhuba uphando olongezelelweyo kunye nokwenza ukuxilongwa. Unyango kulolu hlobo, ukuba kunokwenzeka, lujoliswe ekupheliseni utshintsho olusungulwa kulo mbandela. Kwimeko apho le nto ayifumanekanga, unyango lwendawo luya kunikwa.
