I-hormone Parathyroid: umsebenzi, umthelela emzimbeni womuntu

nezindlala Parathyroid, noma ngaphezulu ngendlela efanele bayobizwa ngokuthi lo parathyroid - ozijameleko abhanqiwe of uketshezi yangaphakathi. Siqukethe amabili namabhuzu encane endocrine nezindlala okweqanda. Basuke etholakala phezu ezingemuva indlala yegilo, izingongolo zalo yasenhla nemithombo yasenzansi.

i-hormone Parathyroid (igama)

i-hormone Parathyroid synthesizes ezimbili. i-hormone Parathyroid - hormone parathyroid (PTH) kanye calcitonin.

Parathyroid i-hormone (PTH) - lena imfihlo eyinhloko emzimbeni. i-hormone Parathyroid lethiwa uhlaka uketshezi yangaphakathi, oveza kubo, okusho kusukela indlala parathyroid. Igama calcitonin liyazikhulumela - ekunciphiseni lokuhlushwa calcium igazi serum.

Kuthiwa ama-hormone, parathyroid , nethonya lazo umzimba womuntu

Sithole ukuthi kufakwa ama-hormone kwemiqondo ndlala parathyroid. Manje ake sixoxe imisebenzi zona banesibopho. hormone Parathyroid kubalulekile ukuze umzimba.

i-hormone Parathyroid (PTH) kuyinto ekhuthaza amaprotheni equkethe yensimbi, i-nitrogen ne-sulphur. Lokhu i-hormone is kuhlelwe umqondo njalo.

• Lapho Kwenziwa ukubanjwa kweqhaza skeleton kanye ekuqongeleleni calcium amathambo - okuyisici esibalulekile lecinisekisa amandla ithambo.
• Ngaphezu kwalokho, imfihlo indlala parathyroid kuvusa osteoclast umsebenzi, okuyinto banesibopho calcium okwesula ithambo lingene egazini. Le nqubo ikuvumela ukuba silondoloze ukulinganisela okufanele phakathi calcium amathambo negazi. Ngaphezu kwalokho, e-nohlaka lwamathambo iqukethe mayelana 99% i-calcium, futhi serum ke% 1 kuphela.
• Calcium ion zinengxenye ukudluliselwa nerve amaza, ukunyakaza kwemisipha contractile. Calcium eqakathekileko igazi uhlelo coagulation kanye oyenza isenzo enzyme ethile.

Calcitonin unesibopho ekunciphiseni calcium lokuhlala egazini futhi kuhlelwe umqondo hhayi njalo kodwa hypercalcemia.

Ngakho, ama-hormone parathyroid nemisebenzi yabo kubalulekile ukuze umzimba womuntu. Ababandakanyeka izinqubo ezibalulekile umzimba.

Isenzo hormone parathyroid kwezinye izitho

Yini ama-hormone parathyroid kubalulekile ithambo, sithole. Manje thina ukugxila imiphumela yabo on nezinye izitho.

• Lokhu i-hormone uzabalaza nemiphumela yayo uhlelo urinary. C excreted ngu izinso ukuboniswa ethile calcium. Le nqubo ithatha indawo ngaphansi kokulawula hormone parathyroid.
• i-hormone Parathyroid kusiza calcium ukumuncwa kusukela emathunjini amancane, lingene egazini.
• Lokhu i-hormone kunciphisa sebethule calcium lens iso.

Hypofunction we ndlala parathyroid

i-hormone Parathyroid at hypofunction yenziwa eziningi enganele. umsebenzi Ababecindezelwe we ndlala parathyroid yiyona okuthiwa tetany, kokuquleka noma ukugula. Ngakho excitability isimiso sezinzwa is kakhulu anda. Kwezinye imisipha ngezikhathi waphawula fibrillar ukusikwa kuphenduke nokuquleka eside. Ezimweni ezimbi kakhulu, Ukudlikizela zisebenza kuwo wonke amaqembu imisipha, kuhlanganise umgudu wokuphefumula, okuholela esifa ngesineke ukuklinya (ukufuthelana).

Endabeni kancane inchubekelembili evilaphayo tetany iziguli zingase zibhekane iziyaluyalu ezihlobene isimiso sokugaya ukudla bungene, izinkinga zamazinyo, nokukhula abampofu izinwele nezinzipho.

hormone Parathyroid silondoloze evamile igazi calcium lokuhlushwa. Ngokuvamile zokhahlamba kusuka 2.1 kuya 2.5 mmol / l. Lapho tetany e serum calcium ezingeni aliphumi ngenhla 2.12 mmol / l. Lokhu kubonakala hhayi kuphela ezicutshini amajaqamba, uvalo kulezi ziguli bevame yokuqwasha.

Hyperparathyroidism

i-hormone Parathyroid e hyperfunction yayo kwemiqondo ngokweqile. Lokhu kungenzeka lapho overactivity kwezinye izingxenye nezindlala endocrine. Lokhu kuholela iziyaluyalu sina elihlobene ne-calcium ukungalingani ku serum igazi. isimo okunjalo kwezinkolo kubizwa ngokuthi hyperparathyroidism futhi kungaholela izinqubo sokugembula:

• osteodystrophy Parathyroid.
• Hypercalcemia.

Izimpawu hyperparathyroidism

izimpawu hyperparathyroidism Primary kukhona nonspecific:

• Nokunganakwa, ukucobeka, nobuthakathaka.
• ucasukile.
• Ukucanuzela kwenhliziyo zincishiswe noma angafuni kudla.
• Ukuqunjelwa.
• Ubuhlungu emalungeni namathambo.

Omunye khetho kungenzeka ezingamahlalakhona hyperparathyroidism hyperfunction nezindlala, lizinga calcium amathambo sinciphile igazi, kunalokho, anda. Amathambo abe ziyaqothuka iziguli ezinjalo, kukhona ukuphazamiseka isimiso sokugaya ukudla bungene, futhi kukhona lapho umuntu enezinkinga ezihambisana uhlelo senhliziyo nemithambo yegazi.

Hyperfunction singenzeka ngenxa senzo parathyroid ihlukaniswe ingxenye. Igazi iziguli ezinjalo kunqunywa inani eleqile calcium ne ngokweqile Ukuqina sekuyenzeka skeleton. Iziguli ingase ibe ukuqunjelwa (uhudo, ukuhlanza). Kusukela isimiso sezinzwa kukhona esincishisiwe excitability, ukucobeka. Nge ukuthuthukiswa kwaleso sifo ingavela watsheka skeleton (ukusonteka we thorax nomgogodla). Iziguli ezinyangeni ezimbalwa kakhulu ukunciphisa umzimba - kuze kufinyelele 10-15 kg 3-4 izinyanga. Kungase kube excitability yesikhashana, okuyinto kamuva zathathelwa isikhundla ukucobeka. Lesi simo sidinga ukwelashwa ngokushesha ngoba Yethulwe ezimweni ezimbi kakhulu, kungaholela ekufeni isiguli. Endabeni ka nezimpawu ezifanayo kufanele silahle ukubona udokotela, kungcono ukuba endocrinology.

Ukwelashwa iziyaluyalu indlala parathyroid

Sithole ukuthi umsebenzi wenziwa ama-hormone parathyroid. Eziyimbangela yezinkinga ezizuzwa nezindlala endocrine ayedinga ukulungiswa. Hypofunction iphathwa lula kakhulu. Isiguli kumele inombolo yemithi nokudla ilungile futhi Kunconywa amaningi bethamele ilanga. Lokhu kuzokwenza ngcono ukumuncwa kwe-calcium umzimba, ngoba salokhu sidinga uvithamini D, wona yakha isikhumba sethu echayeke ultraviolet.

Ukwelashwa hyperfunction komzimba kuphela ukuhlinzwa. Lokhu kuhilela ukususwa kuphela evuvukele ingxenye parathyroid. Qedela ukususwa emzimbeni akukwazi, ngoba kuzoholela Ukudlikizela nenza ukufa isiguli.

i-hormone Parathyroid, nethonya lazo umzimba kubaluleke kakhulu. Isikhathi ukukhomba lapho umuntu enezinkinga ezihambisana umsebenzi ndlala futhi parathyroid nezindlala, ukusiza izivivinyo zokuvimbela neluhlolo emtholampilo. Uma kudingekile, udokotela imithi ultrasound. Nge ucwaningo ezifana ukuthi iyini ngempela inkinga ngesikhathi kuchwepheshe akunzima.
