Antidiuretic hormone kana hormone vasopressin i peptide. Iine mapfumbamwe amino acid masara. Hupenyu hwayo hupenyu hunosvika 2-4 maminitsi. Iyi hormone inobudiswa mumakamuri makuru emakamuri e hypothalamus, uye kubva ipapo inotakurwa kuenda kune neurohypophysis. Kufambisa kunoitwa paxxoni nekuda kweprotein-vectors.
Mabasa ehomoni vasopressin
Basa guru rehomoni ndiro kutonga kwemvura metabolism. Saka, inonzi antidiuretic. Kana kamwechete ye ADH inowedzera mumuviri, ivhu remvura yakabudiswa zvakanyanyisa.
Asi chaizvoizvo zvinoshanduka kuti vasopressin inonzi hormone yakasiyana-siyana uye inoshanda mumutumbi inoita mari inoshamisa. Pakati pezvinhu zvinonyanya kukosha ndeizvi:
- kuwedzerwa ropa rinotenderera richifamba nemidziyo;
- kunowedzera kutenderera kumatomu tema;
- kuwedzera kwemasero eropa emaplatelet;
- kugadziriswa kwezviyeuchidzo;
- kuderedza chiyero chesodium muropa;
- oxyidation ye fatty acids.
Nzira dzevasopressin
Kana chiyero chevasopressin chinopindirana nechimiro mumigumisiro yekuedza, hapana zvikonzero zvekufunganya. Kazhinji tsanangudzo mitemo yakaita seyiyi:
- ne osmolality ye plasma 270-280 musm / kg -
- 280-285 musm / kg -
- 285-290 musm / kg - 1-5 pg / mol;
- 290-295 musm / kg - 2-7 pg / mol;
- 295-300 musm / kg - 4-12 pg / mol.
Maererano neshoko rekuita, mahomoni vasopressin uye oxytocin zvinogona kufungidzirwa zvakafanana. Mhedzisiro huru ndeyokuti iyo yekupedzisira ine maAmino acid masara mashoma. Asi izvi hazviregi kuti hormone irege kuratidza zvimwe zvekuita maererano nekukurudzirwa kwekuchengetedza mukaka, somuenzaniso.
Unyanzvi hwehomoni vasopressin
Kana iyo inhengo mumuviri isingakwanisi, chirwere cheshuga insipidus chinogona kukura. Chirwere ichi chinoratidzwa nekudzvinyirirwa kwebasa rekudzorerwa kwemvura nerinal tubules. Kuderedza uwandu hweAdH hunoshandiswa nekushandiswa kweethanol uye glucocorticoids.
Hyperfunction ye antidiuretic hormone vasopressin
ADH inogona kunyatsobudiswa ne:
- manzwiro uye kushaya muviri zvakanyanya;
- renal failure;
- hepatic insufficiency ;
- kuderera kwehuwandu hweropa rinotenderera pamubhedha wemavhesi;
- acute intermittent porphyria;
- brain tumors;
- pneumonia;
- tuberculous meningitis.
Dambudziko iri kuderera kwehuwandu hweplasma yeropa uye kusunungurwa kwemuti wepamusoro zvakanyanya.
