Parathyroid hormone: muaj nuj nqi, tej yam nyob rau hauv tib neeg lub cev

Parathyroid qog, los yog ntau tshaj kom lawv yuav tsum tau hu ua lub parathyroid - ib qho kev ywj paired hloov khoom nruab nrog ntawm Internal secretion. Nws muaj ob khub ntawm me me endocrine qog kheej li qe. Lawv muaj nyob rau ntawm lub rear nto ntawm lub qog caj pas, nyob rau hauv nws sab sauv thiab sab tug.

Parathyroid hormone (lub npe)

Parathyroid hormone synthesizes ob. Parathyroid hormone - ib tug parathyroid hormone (PTH) thiab calcitonin.

Parathyroid hormone (PTH) - qhov no yog qhov tseem ceeb daim card los ntawm lub cev. Parathyroid hormone tau txais nws lub npe los ntawm qhov hloov ntawm Internal secretion, uas ua rau lawv, piv txwv li los ntawm lub parathyroid caj pas. Ib tug calcitonin lub npe hais lus rau nws tus kheej - kom txhob muaj cov concentration ntawm calcium nyob rau hauv cov ntshav ntshiab.

Cov tshuaj hormones, parathyroid , thiab lawv cov nyhuv rau tib neeg lub cev

Peb pom dab tsi tshuaj hormones yog tsim parathyroid caj pas. Tam sim no wb tham txog lub zog rau cov uas lawv yog lub luag hauj lwm. Parathyroid cov tshuaj hormones yog qhov tseem ceeb rau hauv lub cev.

Parathyroid hormone (PTH) yog ib tug protein compound uas muaj hlau, nitrogen thiab sulfur. Qhov no lawm yog tsim tsis tu ncua.

• Thaum nws yog nqa tawm kev koom tes los ntawm cov pob txha thiab txuam nrog ntawm calcium nyob rau hauv cov pob txha - ib tug tseem ceeb uas saib kuas lub zog ntawm cov pob txha.
• Nyob rau hauv tas li ntawd, ntawm daim card ntawm lub parathyroid caj pas nkoos osteoclast muaj nuj nqi, uas yog lub luag hauj lwm rau calcium ntsoos ntsoos los ntawm cov pob txha mus rau hauv cov ntshav. Qhov no txoj kev tso cai rau koj kom muaj txoj cai nqi koj tshuav ntawm cov calcium uas nyob rau hauv cov pob txha thiab cov ntshav. Ntxiv mus, nyob rau hauv lub skeletal system muaj txog 99% calcium, thiab ntshiab nws tsuas 1%.
• Calcium ions yog muab kev koom tes nyob rau hauv cov kis ntawm cov hlab impulses, nqaij contractile kev ua si. Calcium yog ib qho tseem ceeb feem ntawm cov ntshav coagulation system thiab activates qhov kev txiav txim ntawm tej yam enzymes.

Calcitonin yog lub luag hauj lwm rau cov yuav txo tau ntawm calcium ntau nyob rau hauv cov ntshav thiab yog tsim tsis lossi tiam sis tsuas yog nyob rau hauv hypercalcemia.

Yog li, parathyroid cov tshuaj hormones thiab lawv cov functions yog qhov tseem ceeb rau tib neeg lub cev. Lawv muab kev koom tes nyob rau hauv ib qho tseem ceeb metabolic dab.

Qhov kev txiav txim ntawm parathyroid lawm rau lwm yam kabmob

Yuav ua li cas parathyroid cov tshuaj hormones tseem ceeb heev rau cov pob txha, peb pom tawm. Tam sim no peb siab rau cov teebmeem ntawm tus lwm yam kabmob.

• Qhov no lawm niamntiav nws cov teebmeem rau lub urinary system. C tas los ntawm ob lub raum tso tawm ib qhov nqi ntawm calcium. Qhov no txoj kev yuav siv sij hawm qhov chaw nyob rau hauv cov kev tswj ntawm parathyroid lawm.
• Parathyroid hormone pab calcium haum los ntawm cov hnyuv mus rau hauv cov ntshav.
• Qhov no lawm thiaj li muaj cov calcium deposition nyob rau hauv lub qhov muag lens.

Hypofunction ntawm lub parathyroid caj pas

Parathyroid hormone nyob rau hauv nws hypofunction ua nyob rau hauv tsis txaus ntau. Tsim txom ua si ntawm lub parathyroid caj pas yog lub thiaj li hu ua tetany, qaug dab peg los yog kev mob nkeeg. Yog li excitability ntawm poob siab system yog ho muaj zog. Nyob rau hauv ib co nqaij tsis tseg cai fibrillar contraction xa mus rau hauv ntev-lub sij hawm qaug dab peg. Nyob rau hauv loj heev zaum, convulsions thov rau tag nrho cov pab pawg ntawm cov leeg, xws li cov pa system, uas ua nyob rau hauv tus neeg mob hnub ntawm asphyxiation (txhawm chim).

Nyob rau hauv cov ntaub ntawv ntawm ib tug gradual kev vam meej sluggish tetany cov neeg mob tej zaum yuav muaj mob muaj feem xyuam rau lub digestive system, kho hniav teeb meem, thiab neeg pluag kev loj hlob ntawm cov plaub hau thiab rau tes.

Parathyroid cov tshuaj hormones muaj ntshav calcium concentration. Feem ntau nws yog hom twg los ntawm 2.1 mus 2.5 mmol / l. Thaum tetany nyob rau hauv cov ntshiab calcium theem tsis sawv saum toj no 2.12 mmol / l. Qhov no yog tshwm tsis tau tsuas yog nyob rau hauv cov nqaij tu-sauv, nervousness, thiab cov neeg mob no feem ntau txom nyem los ntawm insomnia.

Hyperparathyroidism

Parathyroid hormone nyob rau hauv nws cov hyperfunction tsim nyob rau hauv excess. Qhov no yuav tshwm sim thaum overactivity ntawm ib co ntawm cov nqe lus ntawm lub endocrine qog. Qhov no ua rau mob loj heev txuam nrog poov hlau tsis txaus nyob rau hauv cov ntshav ntshiab. Xws li ib tug mob no yog hu ua hyperparathyroidism thiab tej zaum yuav ua rau pathological dab:

• Parathyroid osteodystrophy.
• Hypercalcemia.

Cov tsos mob ntawm hyperparathyroidism

Primary hyperparathyroidism tsos mob nonspecific:

• Apathy, nkees, thiab tsis muaj zog.
• Phem mus ob peb vas.
• Xeev siab thiab yuav txo tau los yog poob qab los noj mov.
• Cem quav.
• Mob nyob rau hauv cov pob qij txha thiab cov pob txha.

Ib tug kev xaiv tej zaum yuav mob hyperparathyroidism hyperfunction qog, cov theem ntawm calcium nyob rau hauv cov pob txha yog txo kom tsawg thiab cov ntshav, on qhov tsis tooj, muaj zog. Cov pob txha ua nkig xws cov neeg mob, muaj ib tug teeb meem ntawm lub digestive system, thiab muaj teeb meem txuam nrog rau cov hlab plawv system.

Hyperfunction yuav tshwm sim vim loj hlob ntawm lub parathyroid faib feem. Cov ntshav ntawm tej neeg mob yog txiav txim los ntawm lub dhau heev lawm ntau npaum li cas ntawm calcium thiab tshaj ossification cev pob txha. Cov neeg mob tej zaum yuav kem plab (raws plab, ntuav). Los ntawm lub paj hlwb muaj ib tug txo excitability, nkees. Nrog ntxiv kev loj hlob ntawm tus kab mob yuav tshwm sim lub cev pob txha curving (deformation ntawm lub qab plab thiab tus txha nqaj). Cov neeg mob nyob rau hauv ib tug ob peb lub hlis ntau kom poob ceeb thawj - txog li 10-15 kg nyob rau hauv 3-4 lub hlis. Tej zaum yuav muaj ib tug ib ntus excitability, uas yog tom qab hloov los ntawm nkees. Qhov no mob yuav tsum tau tam sim ntawd kev kho mob vim hais tias Launched nyob rau hauv loj heev zaum, nws yuav ua nyob rau hauv kev tuag ntawm tus neeg mob. Nyob rau hauv cov ntaub ntawv ntawm zoo xws li cov tsos mob yuav tsum tau muab tso tawm mus ntsib ib tug kws kho mob, nws yog zoo dua mus rau lub endocrinologist.

Cov kev kho mob ntawm mob ntawm lub caj pas parathyroid

Peb pom dab tsi muaj nuj nqi yog ua los ntawm parathyroid lawm. Malfunctions ntawm lub endocrine qog yuav tsum tau kho. Hypofunction kho yooj yim dua. Tus neeg mob yuav tsum muab ib tug xov tooj ntawm cov tshuaj noj thiab Noj cov zaub mov thiab yog pom zoo sunbathing. Qhov no yuav ua kom haum ntawm calcium los ntawm lub cev, vim hais tias rau qhov no peb yuav tsum tau vitamin D, uas generates peb cov tawv nqaij yog raug rau ultraviolet lub teeb.

Kev kho mob hyperfunction ntawm lub cev nkaus xwb los ntawm kev phais. Qhov no yuav qhov kev tshem tawm ntawm tsuas yog tus o feem parathyroid. Kiag li tshem tawm cov lub cev tsis tau yuav, vim hais tias nws yuav coj mus uncontrolled convulsions thiab kev tuag ntawm tus neeg mob.

Parathyroid hormone, lawv ntxim rau hauv lub cev yog ib qho tseem ceeb heev. Lub sij hawm los txheeb xyuas cov teeb meem txuam nrog rau kev ua hauj lwm ntawm lub qog thiab parathyroid qog, pab tiv thaiv kuaj thiab soj ntsuam kev xeem. Yog hais tias tsim nyog, tus kws kho mob yuav muab tshuaj rau ib tug ultrasound. Nrog xws li ib tug daim ntawv ntsuam xyuas kom paub tias cov teeb meem nyob rau hauv lub sij hawm rau ib tug kws tsis yog yooj yim.
