STH: nooca kiimikada, saamaynta noolaha ee cudurada

Hormoonnada - walxaha bioactive in ay yihiin dhexsameeysmo jirka oo ku qarisay by qanjidhada hormoonada jidhka si toos ah dhiigga, cerebrospinal ama dheecaanka. Hormoonnada muujiyaan bioactivity sare ee qaadasho miniscule of 10-3 iyo xataa 10-6 mg. Waxay muujiyaan ficil-gaaban ah iyo si degdeg ah halaagnay.

Guryaha hormoonnada.

Waayo, inta badan ee hormoonada tarjunto dhismeedka kelli. Qaar badan oo iyaga ka mid ah waxaa lagu heli qaab saafi ah (folliculin, insulin); qaar ka mid ah iyaga ka mid ah waxaa ku dhexsameeysmo jirka (insulin, adrenaline, cortisone). The hawlaha qanjidhada hormoonada jidhka ah waxaa gacanta ku habka dareemayaasha jirka. Taa baddalkeeda, qanjirka xogta saamayn habka dareemayaasha jirka. Hormoonnada saamayn ku-shiid ee borotiinada, carbohydrates, acids nucleic, subaga iyo macdan.

STH (hormone koritaanka, hormone koritaanka, hormone koritaanka) waxaa go'doonsan ka pituitary ee jilibka Qeybaha Evans iyo Long ee 1921. qanjirka pituitary - waa mid ka mid ah kuwa ugu muhiimsan qanjidhada hormoonada jidhka. Wada jir ah ula hypothalamus oo morphophysiological foomamka nidaam hal, taas oo dejisa-shiid ee jiho oo kala duwan. hormone waa dabeecadda protein ah iyo qaab-dhismeedka oligomeric. Miisaanka uu leeyahay kelli ah 23000-46000 Da. polypeptide hormone Growth ka kooban yahay laba links kuwaas oo ka kooban 191 harta amino acid.

Muuqaalka caan ku hormone koritaanka waa in ay muujinaysaa cayimayo noocyada. Waa in la sheegay in uu yahay koroowga hormone koritaanka kaliya bayoloji firfircoon si aadanuhu.

Marka hypo-dheecaan of cudurada hormoonka koritaanka dhacaan qaar ka mid ah hababka dheefshiidka ee jirka, kuwaas oo geedi socodka dhiska iyo geedi socodka koritaanka. Markii xad-dhaaf ah hormone sii daayo (prostate hyperfunction) da'da hore, ka hor inta bilawga ah ee qaangaadhnimada iyo ilaa dhammaystirka geedi socodkii dhismaha lafaha, waxaa kor loo koritaanka jidhka bini'aadamka, taas oo horseedaysa gigantism. shakhsiyaadka Growth waxaa laga yaabaa in 2 ilaa 2.7 m. hormone koritaanka xad dhaafka ah ee qaangaarnimada keenaysaa in horumarka Acromegaly. Cudurka Tani waxay dhacdaa iyada oo adenomas pituitary iyo kelyaha. Calaamadaha cudurka waa koritaanka ku munaasab ahayn of qeybaha jirka shaqsi, koritaanka xad-dhaafka ah addimada, madaxa iyo juqda unug jilicsan - sanka, dibnaha, carrabka, garka. koror ee xubnaha gudaha, waxaa lagu diiwaangeliyaa hypertrophy qanjidhada hormoonada jidhka qaarkood.

Iyada oo Avv ku filnayn ee hormone koritaanka (hyposecretion) da 'yar waxaa jira haleelay xilligii (haleelay xilligii). Kobaca ma aha in ka badan 90-120 cm, ma sifooyinka galmada sare. dhsan pituitary waa xad saamiyeed si qaab-dhismeedka jidhka, madaxa wax yar ka weyn. Sida iyagu ma ay kala duwan yihiin koritaanka caadiga ah maskaxda ee dadka.

STH saamaysaa geedi socodka dhiska: shidaa biosynthesis ee borotiinada, acids nucleic, waxay kordhisaa heerka sonkorta dhiigga (saamayn diabetic) kicin reticulocytosis, hondro- iyo Osteogenesis.

jidhka bini'aadamka daydaa walxaha badan bioactive, oo na siiyaan dareen wacan (rayn, niyadda wanaagsan, Raalli ahaanshaha). In Kiimikada noole, walxaha waxaa loogu yeeraa neurotransmitters, ayaa ka mas'uul ah gudbinta falalkooda dareemayaasha. Waxaa la rumeysan yahay in serotonin, endorphins iyo dopamine - a hormoonnada ku farxaa. Serotonin - niyadda wanaagsan hormone ah. Marka mudaa dhiigga, u kordhiyaa dhaqdhaqaaqa baabuurta, hagaajinaysaa niyadda. Deficiency of serotonin waxay keeni kartaa niyad-jab. Endorphins yihiin dhexsameeysmo jirka ee xaalado walaac, si loo yareeyo xanuunka. By ku qabanaya in receptors opiat, waxay la xakameeyo xanuunka, sidaas keenaya rayn. Dopamine waxaa badanaa loo yaqaan hormoon ee ku farxaa. The ka weyn-fiirsashada ee xarunta ayaa sheegay in dhiigga, dareenka ifaya.
