Gastrin yog peptide hormone uas txhawb nqa Kev tso tawm ntawm gastric acid (HCl) los ntawm parietal hlwb ntawm lub plab thiab pab nyob rau hauv lub plab motility. Nws tau tso tawm los ntawm G cells hauv pyloric antrum ntawm lub plab, duodenum, thiab txiav txiav. Nws tso tawm yog stimulated los ntawm peptides nyob rau hauv lub lumen ntawm lub plab.
Yog li ntawd, dab tsi ua rau cov qib siab ntawm gastrin?
Txog tam sim no, ob qhov ntau tshaj plaws ua ntawm cov qib gastrin siab yog cov tshuaj tiv thaiv kua qaub uas koj noj rau reflux lossis kub siab thiab mob hu ua mob atrophic gastritis. Ob qho no tuaj yeem ua kev puas tsuaj rau koj lub plab hauv plab. Lawv kuj ua koj lub plab kom ua kua qaub tsawg.
Dab tsi yog lub luag haujlwm ntawm gastrin hauv kev zom zaub mov? Gastrin yog nyob rau hauv lub plab thiab nkoos lub gastric qog kom secrete pepsinogen (ib tug inactive daim ntawv ntawm lub enzyme pepsin) thiab hydrochloric acid . Lub secretion ntawm plab yog stimulated los ntawm cov khoom noj tuaj rau hauv lub plab. Lub secretion yog inhibited los ntawm qis pH. Lwm tus muaj nuj nqi yog tsim los tsim cov tshuaj insulin.
Yog li ntawd, vim li cas gastrin tseem ceeb?
Gastrin Nws yog lub luag haujlwm ncaj qha rau kev tso tawm ntawm gastric acid, uas rhuav tshem cov proteins hauv cov zaub mov koj noj. Gastric acid kuj pab lub cev nqus tau qee cov vitamins hauv cov zaub mov thiab tua ntau cov kab mob uas muaj nyob hauv cov zaub mov. Qhov no pab tiv thaiv lub plab los ntawm kev kis kab mob.
Dab tsi yog cov tsos mob ntawm qib siab gastrin?
Cov cim thiab tsos mob ntawm Zollinger-Ellison syndrome tuaj yeem suav nrog:
- Mob plab.
- Mob plab.
- Kub hnyiab, mob, zom los yog tsis xis nyob hauv koj lub plab.
- Acid reflux thiab kub cev.
- xeev siab thiab ntuav.
- Los ntshav hauv koj lub plab zom mov.
- Tsis txhob poob phaus.
- Ua tsis qab los noj mov.

Cov qib gastrin qhia dab tsi?
Ntsuas ntshav. Thaum nce gastrin tuaj yeem qhia cov qog hauv koj cov txiav txiav lossis duodenum, nws kuj tuaj yeem tshwm sim los ntawm lwm yam mob. Piv txwv li, gastrin kuj tseem tuaj yeem nce ntxiv yog tias koj lub plab tsis ua kua qaub, lossis koj tab tom noj tshuaj txo cov kua qaub, xws li cov tshuaj tiv thaiv kab mob proton
Dab tsi yog suav tias yog qib gastrin siab?
Qib gastrin uas siab dhau yuav tshwm sim los ntawm tus mob hu ua Zollinger-Ellison (ZE) syndrome. Qhov no tuaj yeem txhais tau tias koj muaj qog nyob hauv koj lub plab zom mov uas zais zais gastrin. Cov qog no hu ua gastrinomas. Cov gastrin ntxiv tuaj yeem ua rau cov kua qaub ntau hauv koj cov zom zaub mov
Dab tsi yog gastrin siv rau?
Gastrin yog peptide hormone uas txhawb kev zais ntawm cov kua qaub hauv plab (HCl) los ntawm cov hlwb parietal ntawm lub plab thiab pab hauv plab zom mov. Nws tau tso tawm los ntawm G cells hauv pyloric antrum ntawm lub plab, duodenum, thiab txiav txiav
Vim li cas qhov dav ntawm qhov sib xyaw ua haujlwm muaj peev xwm nce nrog nce kev txhawb zog?
A: CAP yog cov lej sib npaug ntawm txhua tus neeg muaj peev xwm ua tau ntawm cov hlab ntsha. Raws li kev txhawb zog nce ntxiv, peb nrhiav cov fibers ntau dua, yog li ntau APs ntxiv los tsim kom muaj lub tswb zoo li nkhaus
Gastrin yog dab tsi thiab nws txoj haujlwm yog dab tsi?
Gastrin yog peptide hormone uas txhawb kev zais ntawm cov kua qaub hauv plab (HCl) los ntawm cov hlwb parietal ntawm lub plab thiab pab hauv plab zom mov. Nws raug tso tawm los ntawm G hlwb hauv pyloric antrum ntawm lub plab, duodenum, thiab txiav txiav
