Auxin tuaj yeem siv los kho kev loj hlob retardation los ntawm kev loj hlob hormone deficiency.

Kev loj hlob hormone, tseem hu ua human growth hormone (hgh), yog peptide hormone uas raug txwv tsis pub siv hauv kev ua kis las thiab feem ntau siv los kho dwarfism. Nws muaj cov teebmeem hluavtaws thiab metabolic uas ua rau cov leeg nqaij, txhawb cov pob txha loj hlob hauv cov menyuam yaus thiab cov hluas, thiab ntxiv dag zog rau cov leeg thiab cov kabmob hauv nruab nrog cev. Cov neeg ncaws pob siv GH tsis raug cai feem ntau los tsim cov leeg thiab lub zog kom tau txais kev sib tw kom zoo dua.

Raws li cov ntaub ntawv, kev txhaj tshuaj subcutaneous lossis intramuscular yog qhov sib npaug, thiab kev txhaj tshuaj subcutaneous feem ntau coj cov ntshav GH ntau dua li kev txhaj tshuaj intramuscular, tab sis IGF-1 concentration yog tib yam. Kev nqus ntawm GH feem ntau qeeb, nrog cov ntshav plasma GH feem ntau nce siab 3-5 teev tom qab tswj hwm, nrog rau ib nrab-lub neej ntawm 2-3 teev. GH raug tshem tawm los ntawm daim siab thiab lub raum, sai rau cov neeg laus dua li cov menyuam yaus, thiab kev tshem tawm ncaj qha ntawm unmetabolized GH hauv cov zis yog tsawg. Cov Lus Qhia: Txhawm rau kho kev loj hlob qeeb thiab kub hnyiab hnyav rau cov menyuam yaus uas muaj cov tshuaj hormones endogenous tsis txaus, mob raum tsis ua haujlwm, thiab Turner syndrome.

Vim li cas tib neeg txoj kev loj hlob hormone ntau zuj zus tuaj nrog lub hnub nyoog:

Self-feedback loops nyob rau hauv qhov kev txiav txim. Thaum IGF-l txo qis hauv lub cev, cov teeb liab raug xa mus rau lub caj pas pituitary kom zais ntau hGH, thiab qhov kev tawm tswv yim autogenous no txo ​​qis nrog lub hnub nyoog.
