Hormone Parathyroid: umsebenzi, ifuthe emzimbeni womntu

namadlala Parathyroid, okanye ngokuchanekileyo kokukhona baya kubizwa parathyroid - ilungu eyedwa of secretion lwangaphakathi. Liphethe ngambini ezimbini ezincinane kwamadlala ezidalwe elimbhoxo. Bona zibekwe phezu elingasemva nobubovu lengqula, izibonda zaso eliphezulu nengasezantsi.

hormone Parathyroid (igama)

hormone Parathyroid synthesizes ezimbini. hormone Parathyroid - yincindi parathyroid (PTH) kunye calcitonin.

Parathyroid hormone (PTH) - oku imfihlelo iphambili umzimba. hormone Parathyroid got igama layo ukusuka isebe secretion lwangaphakathi, nto leyo uvelisa kubo, ie ukusuka le ndlala parathyroid. Igama calcitonin uthetha kona - ekunciphiseni uyondelelwano lwee- icalcium serum egazini.

Hormone, parathyroid , kunye nefuthe lazo umzimba womntu

Siye safumanisa into hormone kuhlelwe ingaba parathyroid. Ngoku makhe sithethe malunga nemisebenzi abaza banoxanduva. iihomoni Parathyroid zibalulekile umzimba.

hormone Parathyroid (PTH) yikhompawundi protein equlethe intsimbi, nitrogen nesalfure. Le hormone kuhlelwe ngokuqhubekekayo.

• Xa kuliwa inxaxheba amathambo kunye nokwanda ikhalsiyam emathanjeni - into ebalulekileyo eqinisekisa ukuba amandla ithambo.
• Ukongeza, ukuba siyithethe imfihlelo esinobubovu parathyroid ivuselele umsebenzi osteoclast, leyo bajongene calcium kukuyeka ithambo egazini. Le nkqubo ikuvumela ukugcina ukulingana phakathi icalcium emathanjeni negazi. Ngaphezu koko, kule nkqubo skeletal iqulethe malunga ne 99% ikhalsiyam, kwaye serum 1% kuphela.
• ion calcium ababandakanyekayo ekudluliseni neemvakalelo-luvo, kwemisipha contractile. Calcium wenkqubo yinxenye ebalulekileyo kwinkqubo coagulation igazi iyazingenela intshukumo enqanda ezithile.

Calcitonin inoxanduva zokunciphisa ikhalsiyam zoqhaphelo egazini kwaye kuhlelwe hayi rhoqo kodwa kuphela hypercalcemia.

Ngenxa yoko, iihomoni parathyroid kunye nemisebenzi yazo zibalulekile kuba umzimba womntu. Bona inxaxheba kwiinkqubo ezibalulekileyo metabolic.

Isenzo hormone parathyroid kwamanye amalungu

Ziziphi iihomoni parathyroid kubalulekile ithambo, siye safumanisa. Ngoku ingqalelo iziphumo zabo namanye amalungu.

• Le hormone enalo imiphumela yayo kwinkqubo womchamo. C kwazona yi izintso babonisa umlinganiselo othile calcium. Le nkqubo ithatha indawo phantsi kolawulo hormone parathyroid.
• hormone Parathyroid kunceda calcium kukufakwa ukusuka emathunjini amancinci egazini.
• Le hormone kunciphisa calcium nokufumba kwi lens emehlweni.

Hypofunction ngayo le ndlala parathyroid

hormone Parathyroid at hypofunction yenziwa nangokomthamo ayonelanga. umsebenzi nezinqinileyo ingaba parathyroid ke njalo-ebizwa tetany, nokuhlutha izinto okanye ukugula. Ngaloo excitability e-nervous system inyuswe kakhulu. Kwezinye izihlunu athile wabona fibrillar ucutheko ajike abe uxhuzula ixesha elide. Kwiingozi ezimasikizi, unditsho isebenza onke amaqela izihlunu, kuquka inkqubo yokuphefumla, oko kukhokelele iyafa ngomonde ukuphefumla (ukutsarhwa).

Kwimeko apho kancinane progression izigulane tetany elidangeleyo banokufumana nezifo ezinxulumene kwinkqubo yokwetyisa, iingxaki zamazinyo, kunye nokukhula okulambathayo iinwele kunye nezikhonkwane.

iihomoni Parathyroid ukugcina eziqhelekileyo calcium igazi ingqalelo. Ngokuqhelekileyo oku isusela ukusuka 2.1 ukuya 2.5 mmol / l. Xa tetany komgangatho serum ikhalsiyam lingaphumi ngasentla 2.12 mmol / l. Oku kubonakala nje kuphela amahlaba kwezihlunu, ukuxhalaba, yaye ezi izigulane ngokufuthi ubunzima ngenxa ugwayi.

Hyperparathyroidism

hormone Parathyroid e hyperfunction yayo kuhlelwe kwemfuneko. Oku kwenzeka xa overactivity amanye amacandelo kwamadlala yonyango. Oku kukhokelela izifo ezinxulumene calcium ukungalingani serum egazini. Esi simo kuthiwa hyperparathyroidism kwaye kungakhokelela ekubeni iinkqubo zophendlo lwezifo:

• osteodystrophy Parathyroid.
• Hypercalcemia.

Iimpawu hyperparathyroidism

Iimpawu hyperparathyroidism prayimari nonspecific:

• Nokunganaki, silale, nokuba buthathaka.
• olubi.
• Isicaphucaphu kunye nokwehliswa okanye ukulahleka onombilini.
• Nokuqunjelwa.
• Ubuhlungu amalungu kunye namathambo.

Enye indlela isenokuba ezingapheliyo namadlala hyperparathyroidism hyperfunction, inqanaba ikhalsiyam emathanjeni luyacutheka negazi, phezu koko, landa. Amathambo babe izigulane ukudleka ezinjalo, kukho ukuphazamiseka kwenkqubo yokwetyisa, kwaye kukho iingxaki ezinxulumene nemithambo yegazi.

Hyperfunction lunokwenzeka ngenxa ukwanda kwe parathyroid yahlukana nesabelo. Igazi izigulane ezinjalo ugqitywa mali ezingaphezu calcium nokunyoluka kwamathambo skeleton. Izigulane ukuze ukungacoleki (sorhudo, ukugabha). Ukususela luvo kukho excitability kuyehla, silale. Zizinto ngakumbi sifo angavela enomva skeleton (deformation le Isifuba kunye umqolo). Izigulane kwiinyanga ezimbalwa kakhulu ukunciphisa umzimba - up to 10-15 kg ngeenyanga 3-4. Kukho inokuba excitability yethutyana, nto leyo kamva indawo silale. Le meko ifuna unyango ngoko nangoko ngenxa Usungulo kwiimeko kakhulu, oku kungabangela ukufa umguli. Kwimeko neempawu ezifana kufuneka ukhutshwe ukubona ugqirha, kungcono uye endocrinologist.

Unyango ukuphazamiseka le ingaba parathyroid

Siye safumanisa ukuba umsebenzi wenziwa hormone parathyroid. Ezizuzwa kwamadlala ezidalwe kufuneka alungiswe. Hypofunction baphathwe lula kakhulu. Isigulana kufuneka inike inani amayeza nedayethi oluchanekileyo kwaye kucetyiswa Akukho nje. Oku kuza kuphucula ukufunxeka calcium ngawo umzimba, ngokuba le kufuneka ivithamin D, nto leyo elenza ulusu lwethu ubethwa ukukhanya eyingozi.

Treatment hyperfunction umzimba kuphela uqhaqho. Oku kubandakanya ukususwa kuphela inxalenye parathyroid idumbile. Ngokupheleleyo ukususa ayikwazi kuba umzimba, kuba oko kuya kukhokelela unditsho engalawulwayo kunye nokufa isigulane.

hormone Parathyroid, isiphumo zabo umzimba kubaluleke kakhulu. Ixesha aqwalasela iingxaki ezinxulumene nomsebenzi ndlala kunye parathyroid kwamadlala, ukunceda iimviwo zothintelo kunye noviwo clinical. Ukuba kuyimfuneko, ugqirha uyakukumisela ultrasound. Ekubeni uphando abanjalo ukuba babone ingxaki ngexesha i ingcali ayikho nzima.
