E nwere ihe karịrị otu ule nke a ga-eji mee ihe iji chọpụta otú gịroid si arụ ọrụ.
E wezụga nyochaa hormone na-akpali akpali (TSH) ma ọ bụ thyroxine larịị (T4), dọkịta nwere ike iji ule na-akpali akpali nke na-ahapụ ọgwụ (TRH). Nke ahụ kwuru, a na - ejikarị ụdị ule a; n'eziokwu, ọ bụghị na United States, ọ bụ ezie na ọ dị na mba ndị ọzọ.
Ịghọta ule TRH
Iji ghọta otú ule TRH si arụ ọrụ na-arụ ọrụ, ọ na-enyere aka ngwa ngwa iji nyochaa otú ụbụrụ ụbụrụ dị iche iche si emekọrịta na thyroid:
- Gị hypothalamus bụ ụbụrụ nke ụbụrụ gị nke na-ezochi ọgwụ mgbochi-ịtọhapụ hormone (TRH).
- Mgbe TRH na-ahapụ ya, ọ na-eme ka ụbụrụ gị na-eme ka ụbụrụ gị bụrụ nke na-akpali akpali (TSH).
- TSH na-akpali gị thyroid onwe ya ka thyroid hormones.
Ọtụtụ ndị dọkịta na-eji nyocha TSH, nke na-agbatị ọkwa TSH n'ime ọbara n'ọtụtụ oge na oge. A na-akọwa nsụgharị ule TSH ahụ; ọ bụrụ na ọkwa gị dị elu karịa ma ọ bụ dị ala karịa akara aka, a na-ewere ya dị ka ihe àmà nke ọrịa thyroid.
Nyocha TRH dị iche. Nke mbụ, a na-eme nchọpụta TSH nyocha. Mgbe ahụ, a na-enye gị ụdị TRH site na ụbụrụ gị nke na-akpali pituitary gị ịtọhapụ TSH. A na-amịpụta ọbara ọbara nke abụọ na nkeji iri abụọ na iri isii na nkeji, ma ọkwa TSH na -agbagha.
Ụfọdụ ndị ọkachamara na-eche na ule TRH nwere ike ịchọpụta nsogbu ndị na-adịghị mma gịroid ma chọpụta ikike gị nwere ike imeghachi na ozugbo, ma e jiri ya tụnyere nyocha TSH, nke bụ foto nke ọrụ thyroid na otu oge na oge.
Kedu otu ule TRH si esi na nyocha TSH
Nyochaa ule TRH na nyocha nke TSH dị ka ihe nlekọta obi mgbaàmà na- atụle na electrocardiogram, ma ọ bụ nyocha glucose tolerance jiri tụnyere ọkwa glucose ọnụ.
N'ime ule na-akpali akpali, ihe ịma aka ahụ nwere ike ikpughe ihe na-adịghị mma na thyroid.
N'agbanyeghị nke ahụ, ọtụtụ ndị dọkịta na-eleba anya na TSH na-anwale ezigbo ihe ọ bụ naanị otu ntaneti ọbara achọrọ ma ọ bụghị onyinye pụrụ iche. Ọzọkwa, TSH adịghị ọnụ. N'iji ya tụnyere nyocha nke TRH dị oke ọnụ, ọ ga-achọ ka abụọ dị iche iche na-ewepụta ọkara elekere abụọ, ịnweta TRH, na ịmara otu esi arụ ọrụ na ịkọwa ule.
Uru nke TRH Test
A na-eji ule TRH enyere aka chọpụta hypothyroidism nke abụọ (hypothyroidism bụ n'ihi nsogbu pituitary) na hypothyroidism nke isi (hypothyroidism bụ n'ihi ọrịa hypothalamic).
Otú ọ dị, ọ bụ ezie na TRH nwere ike iji chọpụta hypothyroidism nke abụọ ma ọ bụ nke kachasị elu (nke a na-akpọkarị hypothyroidism), ọ pụghị iji ya mee ihe ịmata ọdịiche dị n'etiti ọrịa pituitary na ọrịa hypothalamic.
