Ntoni vasopressin? Hormone vasopressin

Vasopressin - hormone, omnye wemisebenzi engundoqo apho kuphuma ulibaziseko kwaye igcina kwakhona i kwinqanaba eziqhelekileyo ulwelo emzimbeni. Uphuhliso Active of vasopressin ikhuthaza ukusebenza izintso, ngoko ke, kukhuthaza sodium engaphezulu, ngokubonelela ngaloo ndlela kuncitshiswa inqanaba yayo kwengoma egazini. Emva kokugqitywa kuyondelelaniswe kunye nokuveliswa hormone kwi le ngxenye yobuchopho, yena ngesisa "aqukuqela" kwi posa Imisonto-luvo, aze emva koko angene igazi.

Hormone vasopressin - stimulator homeostasis esebenzayo

ekwandiseni imveliso secretion of vasopressin ngokuqhelekileyo waphawula ekunciphiseni kakhulu ubungakanani ulwelo emzimbeni, nokunciphisa umthamo wegazi kunye neqondo osmolarity yayo. Kwiimeko ezinjalo, hormone isebenza homeostasis somfanekiso kunye nemisebenzi ibakhusela kumzimba xa uwonke.

Phakathi iimeko ezinokubangela imveliso asebenzayo vasopressin kukubonelela:

• ukopha ezahlukeneyo;
• amazinga wegazi base-;
• nemiphumela abafumana womchamo;
• emzimbeni.

Kudla kukho States apho hormone vasopressin esebenzayo yaveliswa kungakhathaliseki nokuba yezizathu njongo. Olukhawulezisiweyo le secretion ye ihomoni okuthiwa asanelanga. Ngenxa yoko, ukuvela imikhwa mpilweni enjalo kubonisa ukugula kakhulu ukuba ufuna unesifo esinganyangekiyo.

Hormone vasopressin - umsebenzi

Vasopressin kunempembelelo ngqo eludongeni semithambo, nto leyo exineneyo kwenzeka kuzo, nto leyo yenza ukuba ekwandeni uxinzelelo lwegazi.

Ngenxa ukuveliswa hormone kwi ephilayo, wenza ukuba ummiselo reabsorption fluid kungena kwimijelo zezintso. Olu phawu kunceda ukwandisa umchamo yoxinaniso kwaye kulibazise ukukhululwa yayo.

A sithintelo ekuvelisweni hormone yi le ngxenye kungakhokelela kuphuhliso kwezifo yonyango, umz, isifo seswekile, luphawu enkulu leyo kuphuma ukwanda okubonakalayo umthamo umchamo. Isiphumo na emzimbeni kakhulu.

Indima vasopressin hormone umzimba

Vasopressin le yincindi kwi flow igazi ephawuleka kakhulu ichaphazela ummiselo yokucolwa emzimbeni amanzi. ingqondo Ukwanda hormone egazini kukhokelela ekunciphiseni kwimali umchamo.

Impembelelo vasopressin emzimbeni:

• ukhulisa umva sokufunxa olwelo;
• sodium kukhuthaza esebenzayo egazini;
• ukwanda umthamo kunye wegazi iimpahla;
• inkqubo kusebenze kwizihlunu saturation fluid.

Vasopressin, phakathi kwezinye izinto, onesiphumo esebenzayo ngobume imicu kwezihlunu. Ngaphezu koko, yioxytocin kunye vasopressin - hormone leyo, xa zidibene nefuthe kuyingenelo kwi icandelo kushicilelo nokuthengiswa komsebenzi wabantu kunye negalelo ukuyilwa uxhulumaniso zemithambo zobuchopho ijolise ekulawuleni reactions ndlongondlongo, ukuyilwa iimvakalelo uncamathiselo nabantu ababathandayo. Mhlawumbi le nto yesibini layo igama: vasopressin - nesinika hormone.

Yintoni ebangela kukungabi vasopressin yokuqaphela?

vasopressin okwehlileyo egazini sisesona sizathu yengcinezelo capture fluid kungena kwimijelo kwinkqubo kwezintso kwaye ngenxa yoko - SESWEKILE sinwenwa. Abantu imveliso zaneleyo hormone na nisenza isingqala kumphefumlo unxano rhoqo, imvakalelo of ukoma emlonyeni, omiswe of inwebu yangaphakathi.

Ngaphandle konikezelo ulwelo abantu iphuhlisa emzimbeni, nto leyo sikhatshwa ukwehla kobunzima, ukunciphisa uxinzelelo kwi yegazi kunye nempahla yegazi, inkqubo kwekhono luvo.

Ukuqinisekisa inqanaba vasopressin egazini kunye iimvavanyo zegazi iimvavanyo nomchamo. Noko ke, Amaxesha amaninzi, ezi iindlela zokufumanisa isifo kukho inkcazelo encinane ifuna buhlolwe ngokubanzi.

Vasopressin - hormone ogama amanqanaba ukuze kwehliswe ngenxa yofuzo. Amaxesha amaninzi kuphakama ubunzima kuphuhliso hormone ngenxa kukho ithumba kule ngxenye okanye yebhinqa. Kulo mzekelo, nokuphelisa ingxaki singavuselelwa utyando okanye unyango radiation.

Agqithisile vasopressin egazini

Imveliso ngokugqithisileyo hormone yaziwa ngokuba syndrome engafanelekile antidiuretic secretion hormone, nto leyo ngezifo azixhaphakanga. Obubonakala syndrome ngokwalo yehle plasma ingxinano, kukhuthaza lomchamo kanzulu, amazinga sodium.

Abantu ezinamazinga vasopressin ephakamileyo baxhalabile ngokukhawuleza ukutyeba, isicaphucaphu, intloko ebuhlungu, ukutyhafa, ukungabi namdla. Kuba iimeko okunzima vasopressin igazi kwemfuneko iimeko ezidala ilahleko osezingqondweni, ukufa isiqaqa, inhibition ngokupheleleyo indlela ebalulekileyo imisebenzi yebhunga, nto leyo ekugqibeleni ekhokelela ekufeni.

Ukuphelisa yezifo syndrome yemveliso ngokwaneleyo vasopressin

Okwangoku, uthomalaliso nkqubo ijolise ekwaziseni hormone secretion eziqhelekileyo, oko nokuphelisa le ngezifo ingxaki, nto leyo ebangela uxilongo esebenzayo. Indlela isebenzayo yemveliso ihomoni normalizing kuthathwa ukulawula ukusetyenziswa fluid.

Amaninzi ngexesha unyango prescribers nomonde, amacandelo isandla olubiyele ifuthe vasopressin emzimbeni. Oku amalungiselelo ezonyango ngokuyintloko ezinomthamo lwe Lithium carbonate.

Drug ukubuyisela amanqanaba eqhelekileyo vasopressin

Bunjani inqanaba imveliso kunye nengeniso hormone egazini zisetyenziswa blocker ukuzikisa ingqondo yayo kwi kidney, kwaye ingqondo yebhinqa, phakathi apho iingcali ukhetha, kuqala kwiinto zonke, "phenytoin" yaye "demeclocycline" echaphazela vasopressin. Hormone yagqampa yaya emva kwaye isigulane eyabelwe urea, nto leyo eye inkxaso ukusebenza komzimba.

Ubukho inkqubela ebonakalayo kule ndawo, kwakunye nokuphuhliswa kwezixhobo lokuxilonga mihla kunye namayeza ezintsha kuthetha ukuba lula ukulwa ngempumelelo ngokuchasene syndromes obugqithisileyo kunye nokunqongophala hormone emzimbeni.

Vasopressin - hormone ogama iziphumo emzimbeni ngoku ngenkuthalo babefunda ehlabathini lonke. Kuphela uphethwe ngexesha, kwakunye nokuhambisana kunye neengcebiso leengcali kuvumela ukuba nethemba yabaneziphumo ezihle kuphuhliso syndromes ezinxulumene kumanqanaba vasopressin kakuhle.
