Kuongororwa kweropa kwehomoni yehutori kunogona kurongedzerwa navanachiremba vezvigadzirwa zvakasiyana uye iye zvino ndiyo inonyanya kukurudzirwa kweongororo dzose dzehomoni. Ichi chidzidzo chakakosha kune hafu yevakadzi yevanhu, umo zvirwere zvehutachiona zvinoitika kanomwe kazhinji pane varume. Ngatimbokurukurai zvakadzama, nokuti mahomoni maTTG neT4 ane basa rei, chii chavanogona kuita, uye icho chinogona kurondedzera kukanganisa.
Utachiona hweHymone
Utachiona gland inhengo ye endocrine system, iyo inotora basa rinokosha mukugadzirisa zvirongwa zvakakosha mumutumbi wemunhu. Inoumbwa nehutachiona hunoputika hunobaya nemitsipa, ropa uye lymph vessels. Shchitovidka ine masero anokosha - thyreocytes, anokonzera mahomoni ehutachiona. Mahomoni makuru ehutachiona yeTroid (T3 (triiodothyronine) uye T4 (tetraiodothyronine), iyo ine iodine uye inogadzirwa mune zvakasiyana-siyana.
Synthesis yehomoni yehutori inokonzerwa nekugadzirwa kweimwe hormone - TSH (thyrotropin). TTG inobudiswa nemasero e hypothalamus apo inogamuchira zviratidzo, zvichiita kuti chiitiko chetachiona chiwedzere uye kuwedzera kubudiswa kwehomoni yekemikari. Nzira dzakadaro dzakaoma dzinodiwa kuitira kuti ropa rive rakanyatsonaka riripo sezvinoita mahomoni ane utachiona akawanda, sezvinodiwa mumuviri panguva imwechete.
Maitiro ehomoni yeutachiona TTG uye T4 (isina, huru)
Nhamba yehomoni inonzi TTG inogona kuudza nyanzvi pamusoro pehutano hwehutachiona hwetachiona. Chimiro chacho chinokwana 0.4-4.0 mU / L, asi chinofanira kuonekwa kuti mune mamwe ma laboratori, zvichienderana nenzira yekuedza inoshandiswa, zviyero zvinowanzogona kusiyana. Kana iyo TSH yakakwirira kudarika kukosha kwemugumo, zvinoreva kuti muviri hauchina utachiona-hunokonzera mahomoni (TTG inopindira kune izvi pakutanga). Panguva imwecheteyo, kuchinja kwaTSH kunogona kungoenderana nekushanda kwehutachiona hwehutano, asiwo pamusoro pekushanda kweuropi.
Muvanhu vane hutano, hutachiona hweHroid-stimulating hormone hunochinja mukati maawa makumi maviri nemana, uye chikamu chikuru muropa chinogona kuonekwa mangwanani-ngwanani. Kana TTG yakakwirira pane yakasikwa, inogona kureva:
- kuora mwoyo kwepfungwa;
- matambudziko mukushanda kweglanderedzwa;
- kunyanya kushanda nesimba;
- pamuviri;
- hypothyroidism;
- kusabatwa kwe gallbladder;
- zvakanyanya gestosis, nezvimwewo.
Kusakwana kwakakwana kweTSH kunogona kuratidza:
- thyrotoxicosis;
- kupera kwechimiro chetsitsi yepituitary;
- brain tumors;
- dzidziso yehupenzi muhutano hwetroroid, nezvimwewo.
Iyo utachiona hormone T4 muvakadzi ndeyi:
- rusununguko (rusingabatanidzi neropa reproteine) 0.8-1.9 ng / dl;
- chizere 4.5-12.5 μg / dl.
Nhamba yeT4 inoramba iripo nguva dzose muupenyu hwose. Iyo yakanyanya kuwedzera inowanikwa mangwanani uye munguva yekupedza-yechando. Nhamba yeT4 yakawanda inowedzera nekutakura kwomwana (kunyanya mumutatu wechitatu), asi zvinyorwa zvehomori inosununguka zvingaderedzwa.
Izvo zvinokonzera kuwedzera kwehomoni T4 zvinogona kuva:
- kuneta;
- toxic goiter ;
- kuvhiringidza zvirongwa mumatomu e thyroid;
- HIV utachiona;
- chiremara chakaipa chechibereko, nezvimwewo.
Kuderedza kuwanda kwetachiona hormone T4 kunowanzoratidza zvirwere zvakadai:
- kushayikwa kweodhini mumuviri;
- autoimmune thyroiditis ;
- kukanganiswa kwe hypothalamus;
- neoplasms muhutano hwetroroid, nezvimwewo.
