YUAV TSUM SIV

Gastrin, tseem hu ua pepsin, yog lub plab zom mov feem ntau zais los ntawm G hlwb ntawm plab antrum thiab duodenum thiab ua lub luag haujlwm tseem ceeb hauv kev tswj lub plab zom mov thiab tswj cov qauv ntawm plab zom mov.Gastrin tuaj yeem txhawb kev ua kua qaub hauv plab, pab txhawb kev loj hlob ntawm cov kab mob hauv plab hnyuv, thiab txhim kho cov khoom noj khoom haus thiab cov ntshav ntawm mucosa.Hauv tib neeg lub cev, ntau dua 95% ntawm cov tshuaj lom neeg gastrin yog α-amidated gastrin, uas feem ntau muaj ob isomers: G-17 thiab G-34.G-17 qhia cov ntsiab lus siab tshaj plaws hauv tib neeg lub cev (kwv yees li 80% ~ 90%).Kev zais ntawm G-17 yog nruj me ntsis tswj los ntawm pH tus nqi ntawm lub plab antrum thiab qhia tsis zoo tswv yim mechanism uas txheeb ze rau gastric acid.

Cov khoom siv no yog npaj rau kev tshawb nrhiav hauv vitro kom pom cov ntsiab lus ntawm Gastrin 17 (G-17) hauv tib neeg cov ntshav ntshav / ntshav / kuaj ntshav tag nrho.Cov khoom siv no tsuas yog muab cov txiaj ntsig ntawm Gastrin 17 (G-17).
