Oncotic kumanikidzwa

Nomuzvarirwo oncotic kumanikidzwa (ine chete osmotic) - yeimwe mudutu vakaumba zvinhu ropa uye plasma. With yokushomeka kwemapurotini pamuviri iri shoma, izvo zvingaita kuti chokwadi kuti nokuda kuunganidza edema Urume uchatanga kuoneka. Izvi imhaka ndechokuti Kamudzira mudziyo masvingo vari translucent uye semipermeable. Vane zvakanaka uye pachena Zvino mvura, ukuwo ions uye mamorekuru dzakasiyana zvinhu - kuipa.

Normal oncotic kumanikidzwa anenge 7.5 ATM. (5700 mm HG kana 762 kPa). Basa zvinosiyana munzvimbo plasma nharaunda 290 mOsm / l.

Zvisinei, mashoko osmotic kumanikidzwa kunoyerwa kwete kwazvo ichiputswa mamorekuru, sezvo avo yevasungwa. Vazhinji plasma ions (anenge 99,5%) ndiwo inorganic ions, wevasungwa izvo kunoenderana oncotic kumanikidzwa. Kwokudzvinyirira kwomunhu mapuroteni eplasma kunongova chikamu chiduku zvose 0.03-0.04 ATM. (25-30 mm HG). Asi zvinokosha kuyeuka kuti kumanikidza kunoitwa mapuroteni kunokosha akaoma pakuzadziswa pakugoverwa mvura pakati plasma uye chikuru nyama.

chikamu ichi nzira uye funga kuziva oncotic kumanikidzwa. Kupindura kwake kuparadzira mvura zvinoratidzwa chokwadi kuti masvingo capillaries zvikurukuru safambika nokuda mapurotini. The interstitial Urume mapuroteni duku zvikuru, saka avo wevasungwa gradient inotengwa pamusoro mativi ose rirambe richibvira.

Nokuda mukuru oncotic kumanikidzwa kuti mvura iri intercellular nzvimbo asingadi kuunganidza uye circulates.

Nokuti kudzivirira oncotic kumanikidzwa yakarumbidza Mabatirwo preeclampsia, ndiro zvikuru guru-kuti mugumisiro anozviramba refu. With kwomuzvarirwo kweropa mapuroteni normalize nayo, vachibvumira yekuzvidzivirira chemwoyo.

Oncotic BP inowanzopiwa wakachengetwa kugara pamwero. In yayo neurohumoral murau havagovani excretory nhengo akadai ziya omumuviri , neitsvo. Kuderera kana kuwedzera oncotic kumanikidza vachinzwisisa pamusoro arikunze ari mudziyo madziro uye mugove nechepakati (the hypothalamus) apo antidiuretic kemikari ukasunungurwa kunokanganisa Absorção de Água kwacho itsvo makwara. Its basa iri waidzora weti inotungamirwa rikurumidze. Kutsiga osmotic kumanikidzwa kupa DNA, aldosterone, parathormone, urenichesky cardiac kemikari.

By dzepanguva kunoitika muna allocating nhengo kushandura zvinhu kana zvinoguma kunyanya kunonoka, kana kungoerekana kurasikirwa Urume uye munyu mumuviri. In azvaiitwa, wokutanga uye ringareva basa rinoenderera mapuroteni (oncotic kumanikidzwa) iro vanokwanisa kusunga uye kusunungurwa ions. Kuburikidza mabasa excreting nhengo (itsvo uye ziya mumasero), metabolic zvigadzirwa, zviri ichi- kuumbwa muviri, vazhinji vavo vasina inokanganisa pamusoro osmotic kumanikidzwa.

Zvirwere oncotic kumanikidzwa pamwero vari vawadzane kusaenzana zvachose mapuroteni yeplasma albumins uye globulins, anions, cations, yavaibvisa, potassium, calcium nezvimwe zvinoriumba. Izvi zvinogona kukonzerwa siyana pathological ezvinhu uye zvirwere (chikokiyana, kutsva, post-kushanda nguva, kuvhunduka, ropa, zvirwere zvakasiyana-siyana, uye zvakafanana). Muzviitiko zvakadaro, tarisa oncotic kumanikidzwa kunokosha zvikuru kuti nguva dzose. Treatment anonyanya kutaurirwa kubvisa zvinokonzera chirwere uye kudzorerwa pakuenzanisa munyu iri muropa plasma. Zvisinei, usati kubata kufurirwa, kunyanya oncotic, iva nechokwadi kuti bvunza chiremba wako. Regai kuzvidzora medicate!
