Ko vasopressin? The kemikari vasopressin

Vasopressin - kemikari, mumwe mukuru mashandiro izvo makabuda kunonoka uye kudzorera chakaipa mvura pamwero mumuviri. Active kukura vasopressin inosimudzira activation etsvo uye, naizvozvo, kuti excretion yebongozozo yavaibvisa, ichipa saka kuderedza mwero yaro ropa sezvamunoita. Pamusoro kuvakwa kwetunhu uye kugadzirwa kwezvinhu kemikari iri hypothalamus uropi, iye pachena "runoyerera" iri pituitary shwanu tsinga fibers, uye ndokusunungurwa kupinda ropa.

Kemikari vasopressin - basa stimulator homeostasis

Kwakawedzera uye secretion kuti vasopressin zvinowanzochengetwa panguva yekudyidzana kuderedza huwandu mvura mumuviri, kudzikira ropa vhoriyamu uye huwandu kwayo osmolarity. Muzviitiko zvakadaro, kemikari anoita somunhu stabilizer homeostasis uye anodzivirira mashandiro anoita nhengo rose.

Pakati ezvinhu anogona kukonzera zvinoshingaira kugadzirwa vasopressin ndiko kupa:

• siyana ropa;
• chichiburutswa BP mumatunhu;
• Migumisiro kugamuchira diuretics;
• kupera mvura mumuviri.

Kazhinji kune inoti umo zvinoshingaira kemikari vasopressin anogadzirwa pasinei chinangwa zvikonzero. Yakaitawo secretion ane kemikari inonzi kukwana. Uyewo, kuti chidzoke vakadaro hakuvaki kuitikawo zvingaratidza kuti ane chirwere chakakomba rinoda anokwanisa kuongorora chirwere.

The kemikari vasopressin - shanda

Vasopressin ine rakananga zvainoita vascular porusvingo, zvichiguma aienda kunoitika navo, izvo zvinozoita kunotungamirira kuwedzera BP.

Nokuda kugadzirwa kemikari iri muviri, kwakaita kuti mutemo mvura reabsorption ari itsvo makwara. Nyaya iyi kunobatsira kuwedzera weti wevasungwa uye kunonoka kwayo kusunungurwa.

A zvakaipira kweShanduro kemikari parutivi hypothalamus kungaita kuti pave kwemakemikari anobudiswa zvirwere, semuenzaniso, chirwere cheshuga, chikuru chiratidzo izvo makabuda kuwedzera weti vhoriyamu. Mugumisiro kwakakomba kupera mvura mumuviri.

Basa kemikari vasopressin kuti muviri

Vasopressin iri hormone muropa aibuda iyo Chinonyanya kuoneka kunokanganisa mutemo muviri mumuviri mvura. Inosimudzira Kuwanda kemikari muropa kunotungamirira kune zvinoderedza uwandu weti.

Igaroziva vasopressin pamusoro muviri:

• pakurera shure kubvisa pamusoro mvura;
• rinoita yavaibvisa excretion kubva ropa;
• kuwedzera Vhoriyamu uye BP nenhumbi;
• activation muitiro Urume saturation munyama.

Vasopressin, pakati pezvimwe zvinhu, ine basa zvainoita mamiriro ari tsandanyama fibers. Uyezve, oxytocin uye vasopressin - hormone iyo, kana kukabatanidzwa kubatsira kukanganisa ungwaru chezvinonhuwira webasa evanhu uye zvinobatsira kuti paumbwe Neural kwokubatana uropi zvainanga nokudzora hasha siyana, paumbwe nemanzwiro kutyira vadiwa. Zvichida ndokusaka wechipiri ayo zita: vasopressin - hormone kuvimbika.

Chii chinokonzera kushayikwa vasopressin kwetunhu?

Akaderedza vasopressin kupinda ropa iri kukonzera udzvinyiriri kubatwa mvura iri renal ino hova uye somugumisiro - vanorwara mellitus. Vanhu vane kukwana kugadzirwa kemikari anogona anotambudza nyota kuramba, manzwiro ose kuoma mumuromo, nokuomesa womunhu mucous membranes.

Pasina kuwana mvura nevanhu anovandudza kupera muviri, izvo achiperekedzwa uremu, achidzikisa kumanikidza ari arteries nemidziyo ropa, tsinga dysfunction.

Kuona padanho vasopressin muropa nemiedzo ropa uye weti nemiedzo. Zvisinei, kazhinji, chirwere nzira idzi mashoko shoma kuti inoda mamwe kuongorora.

Vasopressin - hormone vane nhanho anogona kudzikiswa nokuda nemagene kubatwa. Kazhinji zvinetso kukura kemikari somugumisiro kuvapo bundu iri hypothalamus kana pituitary. Panyaya iyi, kubviswa dambudziko zvinogoneka kuburikidza kuvhiyiwa kana mwaranzi mishonga.

An nekumwisa vasopressin muropa

Kunwisa Kugadzirwa kemikari rinozivikanwa urwere pakati kukodzera antidiuretic kemikari secretion, inova ishoma zvokurwara. Kuratidza chirwere tichitarisa yadzikira arambe achirema plasma, excretion ane pfungwa yokushanda weti, kuwedzera kwevari yavaibvisa.

Vanhu vane yakakwirira vasopressin yomuropa vane hanya nokukurumidza kufuta, kuda kurutsa, kutemwa nomusoro, utera, kurasikirwa kudya. For Muzviitiko zvakaipisisa yebongozozo ropa vasopressin mamiriro ezvinhu anokonzera kurasikirwa pfungwa, pakoma, chinovhiringidza zvakakwana zvinokosha mashandiro anoita muviri, izvo pakupedzisira inotungamirira kurufu.

Kubviswa pathological chirwere rwakakwana kugadzirwa vasopressin

Pari mishonga iri unopfuura zvainanga kuunza kemikari secretion chaiko, ndicho kubviswa dambudziko zvokurwara, iro rinoita basa zvawanikwa. Nzira dzakawanda rine unyanzvi normalizing kemikari Kugadzirwa anoonekwa kudzora mvura mvura rinodyiwa.

Kazhinji panguva kurapa murwere prescribers, zvinoriumba iyo pave ichivharira mugumisiro vasopressin pamusoro muviri. Izvi anonyanya dzokurapwa kugadzirira ane kugutsikana kuti lithium carbonate.

Drug kudzorera chakaipa kwevari vasopressin

Kuti normalize padanho kugadzirwa uye mari yacho kemikari muropa anoshandiswa blockers yawo wevasungwa munguva itsvo, uye pituitary shwanu, ramakagadzwa nyanzvi vanosarudza, pakutanga kwezvose, "phenytoin" uye "demeclocycline" kukanganisa vasopressin. Kemikari gwa shure uye murwere basa urea, izvo kutsigira zvainoita muviri.

Kuvapo kuchikosha mberi munzvimbo ino, uyewo kugadzirwa kwepurogiramu ano chirwere midziyo pamwe mishonga yemazuva zvinoreva aivabatsira chinobudirira pakurwisana syndromes yebongozozo uye kuperevedza kemikari mumuviri.

Vasopressin - hormone ane migumisiro iri muviri zvino nokushingaira kudzidza pasi pose. vachinyatsoziva nechirwere, uyewo zvaidiwa kunenge nenyanzvi chete anotibvumira kuti tariro yakanaka mugumisiro kukura syndromes chokuita vasingadzoreki vasopressin mumatunhu.
