Thyroid goiter

Follicles ma sela epithelial - nei le faavae iunite tau fausaga ma e faaaogaina o le puna thyroid. O le vaega autu o se colloid porotini - thyroglobulin. O le lotoa Igoa e faatatau i glycoproteins. O le biosynthesis o homone thyroid ma o latou valavala i le bloodstream lo o pulea e thyrotropin pituitary anterior (TSH), o lona tuufaatasia ua stimulated ma inhibited e somatostatin pituitary tireoliberinom. Afai e faaitiitia le faasalaga o vaimū i le galuega tauave pituitary hormone thyroid toto ma le le lava - faateleina. Faateleina o faasalaga o TSH faaosoosoina e le gata faagasologa amplification iodinated hormone biosynthesis, ae faasalalauina foi po o hyperplasia nodular o le aano o le tino o le puna thyroid.

Auga o faamai thyroid ua faia e faaaoga ai togafitiga, metotia pathological ma biochemical ma morphological. ua faatulaga e faavae ua taua i lalo i luga o le faamatalaga maua faamai: faatetele goiter, hypothyroidism, Graves 'faamaʻi, goiter utuvā, patu prostatic.

faamaʻi 'Graves e faamatalaina i le hypersecretion o thyroid homone ma hypertrophy faasalalauina o le puna thyroid. O lenei pathology ua manatu se faamaʻi autoimmune genetically puluvaga e tuʻufaʻasolo mai i tupuaga. Faaoso atinae o goiter faamai pipisi (fulū, parainfluenza, inflyuensa), pharyngitis, tonsillitis, encephalitis, popole, ma le faaaogaina mo se vaitaimi umi o sauniuniga vaimū. Uiga mo le o faasalalauina faamaʻi (o nisi taimi faʻapōuliuli) faateleina cachexia thyroid.

Hashimoto e faatatau i se faamaʻi autoimmune faamatalaina i le manuʻa o le puna thyroid, faaletonu tuufaatasia hormone. O lenei pepa tireroidita faamatalaina i le faaitiitia tuufaatasia o homone (triiodothyronine, thyroxine) ma hypertrophy thyroid. O lenei pathology e sili atu e ono mafai ona faamauina i tamaitai nai lo alii.

goiter faatetele o le puna thyroid - o se faamai faaumiumi faamatalaina e se faateleina o le glands endocrine, solia o ana galuega tauave, metabolism, faaletonu o le faiga popole ma cardiovascular. Faaletonu o synergists vaimū (metala paʻepaʻe, cobalt, kopa, manganese) ma sili tagata tetee (kalisiu, strontium, taitai, bromo, magnesium, uʻamea, fluorine) fesoasoani i le faalauteleina o le faamai.

E le gata i le atinae goitre faaletonu vaimū amataina e aai aofaiga tele o oloa ma sui antithyroid (goitrogens). I lenei tulaga, ua le atiina ae o goiter nontoxic o le puna thyroid. e faaitiitia tuufaatasia faaletonu vaimū faaumiumi o T3 ma T4. Ona o nei biochemical suiga i le tino auala taui e aofia ai, aemaise lava, faateleina secretion o TSH hyperplasia atiina ae prostate (parenchymal thyroid goiter). I le faaopoopo atu, o le adsorption o vaimū e le puna thyroid faalauteleina (4-8 taimi) faateleina tuufaatasia hormone T3, gaoioiga moni o 5-10 taimi e maualuga atu nai lo le thyroxine. I auala taui lumanai te le atoatoa aveesea ai le aafiaga leaga o le tupe pau vaimū taimi umi. atrophied pepa solo glandular le puna endocrine, ua faia cysts, adenoma, ae o le atiina ae o connective pepa solo ua le atiina ae o thymus hypertrophy o le puna thyroid. Ina ua le auga o le "thyroid goiter" faalavelaveina lipid, carbohydrate, porotini, ma vitamini ma metabolism minerale.
