Lapho beqeda zamagama kanye ukukhiqizwa hormone kule ngxenye yobuchopho, ngokukhululekile "ugeleza" kule ndlala pituitary ka yezinzwa, badedelwa lingene egazini.

I-hormone vasopressin - asebenzayo stimulator homeostasis

umkhiqizo wawanda futhi uketshezi of vasopressin ngokuvamile obaphawuleka kunciphise inani uketshezi emzimbeni, nokuncipha igazi ivolumu kanye nezinga osmolarity yayo. Ezimweni ezinjalo, i-hormone uba homeostasis isimame futhi imisebenzi okuvikela umzimba iyonke.

Phakathi izimo ezingabangela ukuba ukukhiqizwa esebenzayo ye vasopressin wukunikeza:

• ukopha ezihlukahlukene;
• kwehlisa amazinga umfutho wegazi;
• imiphumela kokuthola isisu;
• ukuphelelwa amanzi emzimbeni.

Ngokuvamile kukhona uthi lapho asebenzayo i-hormone vasopressin ikhiqizwa kungakhathaliseki izizathu inhloso. Yashesha uketshezi of ihomoni okuthiwa yi ingafaneleki. Ngakwelinye ihlangothi, ukuvela enjalo Amathrendi okungenamsoco kungase kubonise ukugula okungathí sina okudinga ukuxilongwa oqeqeshiwe.

Hormone vasopressin - umsebenzi

Vasopressin liyithinta ngokuqondile ku odongeni semithambo, okuholela ukuvaleka kwenzeka kubo, nakho kuholela ekwandeni wegazi.

Ngenxa ukukhiqizwa hormone e umzimba, konke kwenza ukulawulwa reabsorption oketshezini iziteshi izinso. Lesi sici sikusiza ukuba wandise umchamo okuhlushwa alibale ikhishwe.

A kusimo ekukhiqizeni hormone ngu hypothalamus kungaholela ukuthuthukiswa izifo endocrine, isib, isifo sikashukela, uphawu enkulu lapho kuphuma nokwanda okuphawulekayo umthamo umchamo. Umphumela amanzi emzimbeni ezinzima.

Indima vasopressin i-hormone emzimbeni

Vasopressin kuyinto hormone e ukugeleza kwegazi okuyinto ephawuleka kakhulu kuthinta ukulawulwa umzimba emzimbeni yamanzi. okuhlushwa Ukwandiswa hormone egazini kuholela ukuncipha inani umchamo.

Umthelela vasopressin emzimbeni:

• ukhulisa emuva ukuncela uketshezi;
• asebenzayo sodium excretion kusukela egazini;
• ukwandisa umthamo wegazi lazo wawungcono izitsha;
• inqubo ukusebenza uketshezi ukugcwaliswa kwezicubu.

Vasopressin, phakathi kwezinye izinto, kuba nethonya asebenzayo isimo le micu kwemisipha. Ngaphezu kwalokho, oxytocin futhi vasopressin - hormone okuyinto, lapho kuhlangene umthelela ezuzisayo phezu ingxenye bokusungula umsebenzi womuntu kanye nomthelela ekwakhekeni ukuxhumana kwemizwa zobuchopho okuhloswe ngaso ukulawula ukusabela nolaka, ukwakheka imizwa ukunamathela abathandekayo. Mhlawumbe yilesi sizathu esenza yayo yesibili igama: vasopressin - ukwethembeka hormone.

Yini ebangela ukungabi vasopressin zamagama?

vasopressin encishisiwe lingene egazini kuyimbangela eyinhloko njengesinkwa nokucindezeleka njengamanzi bamba oketshezini kwezinso iziteshi uhlelo futhi ngenxa yalokho - of ngifundise ngesifo sikashukela. Abantu lokukhiqiza enganele we lama-hormone lingase ukuhlupha ukoma njalo umuzwa we ukoma emlonyeni, omiswe nolwelwesi lwamafinyila.

Ngaphandle ukufinyelela ketshezi abantu eba amanzi emzimbeni, okuyinto kuhambisana kwesisindo, ukunciphisa umfutho imithambo kakhulu futhi imithambo yegazi, kwemizwa uhlelo ukungasebenzi.

Kutholakale izinga vasopressin egazini ne ukuhlolwa kwegazi ne ukuhlolwa umchamo. Nokho, ngokuvamile, lezi izindlela zokuxilonga kukhona ulwazi oluncane edinga ukuhlaziya olunye.

Vasopressin - hormone kabani amazinga kungenzeka kwehliswe ngenxa yofuzo. Ngokuvamile kuvela izinkinga ukuthuthukiswa hormone ngenxa khona isimila kule ngxenye noma pituitary. Kulokhu, ukuqedwa inkinga kungenzeka ngokusebenzisa ukuhlinzwa noma ukwelashwa ngemisebe.

Ngokweqile vasopressin egazini

ukukhiqizwa ngokweqile hormone is njengoba syndrome ka okungalungile antidiuretic i-hormone uketshezi, okuyinto zokugula kancane esivamile. Izenzo syndrome ngokuya kwehle ukuminyana plasma, excretion of a umchamo kanzulu, bandise sodium.

Abantu ngamazinga vasopressin isigqugquzeli ukhathazekile okusheshayo kwesisindo, isicanucanu, ubuhlungu bekhanda, ubuthakathaka, ukungakuthandi ukudla. Ukuze izimo ezinzima ngokweqile igazi vasopressin izimo ezibangela nokulahlekelwa ukwazi, ikhoma, okusithiyayo ephelele obalulekile imisebenzi yomzimba, okwagcina kuholela ekufeni.

Ukuqedwa sokugembula syndrome ukukhiqizwa ukungadli vasopressin

Okwamanje, indlela yokwelapha is ngokuyinhloko okuhloswe ngaso ngokuletha i-hormone uketshezi ukuze evamile, ukuqedwa zokugula engaphansi, elibangela uphethwe asebenzayo. Indlela esebenza kahle kakhulu ukukhiqizwa kwama-hormone normalizing kubhekwa ukulawula ukusetshenziswa uketshezi.

Kwakuvamile ukuba phakathi ukwelashwa prescribers nesineke, izingxenye ezinomthelela Ukuvinjwa umphumela vasopressin emzimbeni. Lena amalungiselelo yezokwelapha ngokuyinhloko ne wokuqukethwe ka lithium carbonate.

Izidakamizwa ukubuyisela amazinga evamile vasopressin

Ukuze kulesetayelekile ezingeni zokukhiqiza kanye engenayo le-hormone egazini asetshenziswa blocker emakamu yayo izinso, futhi indlala pituitary phakathi okuyinto ochwepheshe uthanda, okokuqala kunakho konke, "phenytoin" futhi "demeclocycline" ezithinta vasopressin. I-hormone ayibhampise emuva esigulini inikezwa urea, eye asekelayo nomthelela emzimbeni.

Ukuba khona inqubekela phambili enkulu kule ndawo, kanye nokuthuthukiswa imishini yesimanje zokuxilonga kanye imithi ezintsha kusho ukuthini lula ukulwa ngempumelelo yokulwa syndromes ngokweqile futhi nokushoda hormone emzimbeni.

Vasopressin - hormone kabani imiphumela emzimbeni manje ngenkuthalo wafunda emhlabeni wonke. uphethwe ngesikhathi esifanele, ukuthuthukiswa kwezinkampani kanye nokuhambisana ne izincomo ochwepheshe kuphela evumela ukuba silangazelele umphumela omuhle kakhulu ekuthuthukeni syndromes ezihambisana ne amazinga vasopressin kahle.
