Kukura kwehomoni (STH), sezvinonziwo, kukura kwehomoni, chinhu chepuroteni chaiyo inogadzirwa mune anterior pituitary gland. Basa guru rinoitwa naye ndiro kukurudzira kukura, uye sechikonzero - kuwedzera kwehukuru hwemuviri. Izvi zvinoitwa kuburikidza nekushandiswa kwevanabolic nzira. Mukuwedzera, iyi hormone inowedzera basa remafuta, makhahydrates, uyewo mineral metabolism.

Chii chinogadzirisa kuwedzera kwekukura kwehomoni mumuviri?

Zvose izvi zvinonzi biosynthesis uye kuchengetedzwa kwemashure ekuwedzera kwehomoni kunobva kune zvakasiyana-siyana zvinoshandiswa nehutachiona, kunyanya zvipembenene zvemukati, kune muviri. Iro iyo nzira yekugadzirisa inotungamirirwa ne hypothalamus, kunyanya neyourohormones yayo.

Mhedziso ye STH mumuviri inogadzirwa ne insulini-yakafanana, kukura kwezvinhu, uye inobva pane zvose zviyero uye basa rezvinyama zvinogamuchirwa zvehomoni.

Izvozvo zvakadini kuderera kwekudzivirirwa kweSH mumuviri?

Izvo zvakanyanya kukura hormone inoderedzwa muhuduku. Kana izvi zvisiri kuonekwa munguva uye zvisati zvaruramiswa, kukura kwevanhu vakadaro hazvipfuuri 130-140 cm. Panguva imwe chete, kuderera kunowirirana nehukuru hwemuviri hunoonekwa, iyo inozivikanwa mumishonga se splanchnomycria. Mune varwere vakadaro, mahomoni uyewo matambudziko emagetsi anowanikwa zvakare. Saka kazhinji kacho kufanana kunowedzera.

Chii chinoitika kumuviri wekuwedzera zvakanyanya kweSHH?

Kukura kwehomoni kunogona kuwedzerwa mumuviri mushure mekutupa kwepituitary ye-hormone-producing nature. Panguva imwe chete, zvichienderana nesiteji iyo chirwere chinowanika, zvirwere zviviri zvemakiriniki zvinoratidzika:

1. Mune vana, avo vane maitiro ekutsvaga kusati apera, kune kuwedzera kwakakura kwekukura kwefupa, zvichiguma nekugadzirwa kwegigantism.
2. Kana chirwere ichi chikaitika kune vanhu vakuru vane kushambadzira kwenguva refu, kune kuwedzerwa kwepfupa kukura muhupamhi, izvo zvinozopedzisira zvichiita kuti kuwedzerwa kwehuwandu hwezvinyorwa zvechirasi. Somugumisiro, pane kuwedzera kwemapfupa emasaga, pamwe chete nekumira, kududzirwa kwezvibatanidzwa, kuwedzera mumhino uye nzeve dzekunzwa. Ini, mune mamwe mazwi, acromegaly inokura.

Kuwedzerwa kwemazinga emagopa eropa muropa kunogona kukonzerwa nekushandisa mishonga, kunyanya, ine glucocorticoids uye progesterone.

Ndeipi nhamba ye STH mumuviri inofanira kuva yakajairika?

Muyero wekukura kwehomoni muropa unochinja nezera. Panguva imwecheteyo, nokuda kwekurapwa kwepakutanga uye kurapwa panguva yakakodzera, zvinonyanya kukosha kudzora huwandu hwekukura kwehomoni muvana. Nhamba yaro inoshanduka seyizvi:

• vana vana makore 1-3: vakomana (m) - 0.43-2.4 ng / ml; vasikana (e) - 0.5-3.5;
• 4-6 makore: m - 0,09-2,5; d - 0,1-2,2;
• 7-8 makore: m - 0,15-3,2ng / ml; d - 0.16-5.4;
• 9-10 makore: m - 0.09-1.95 ng / ml; д - 0,08-3,1.

Kana iwe uchifungidzira hutachiwana hwevana, kuongororwa kunogadzirwa nehuwandu hwekukura kwehomoni, mhedzisiro yayo inofananidzwa nehutsika. Muchiitiko ichi, panzvimbo yekutanga funga nezvezera remwana.

Kana ari vanhu vakuru, chimiro chemu hormone iri muropa iri kusvika ku 1.0 ng / ml. Zvisinei, kukwirira kwehutachiona, somuenzaniso, muAcromegaly, kunosvika mumusana we 40-80 ng / ml. Kuwedzera kwei hormone kusvika kune ichi chiyero kunowanikwawo kune:

• gigantism;
• CRF (kusagadzikana kwechirwere chekushaya simba );
• hyperglygic ;
• matumbo mumapapu, mudumbu.

Nokudaro, nekukura kwemwana kunonoka kumashure, kunyanya kukosha kwekutsvakurudza kwenguva yakakodzera yehutachiona, ndiko kukura kwehomoni.
