Secretin is a hormone that regulates water homeostasis throughout the body and influences the environment of the duodenum by regulating secretions in the stomach, pancreas, and liver. It is a peptide hormone produced in the S cells of the duodenum, which are located in the intestinal glands . [3] Under normal physiologic conditions, secretin inhibits gastrin release; however, in gastrinoma pathologies, the administration of secretin will cause an overall increase in gastrin release. This idea is the basis for the secretin stimulation test, which is used to determine the presence of gastrin-producing tumors. Proper technique of the ガストリンは 胃酸の分泌を促進する 働きがあります。 つまり、胃における食物の消化を促すために分泌されるホルモンといえます。 ちなみにガストリン分泌が高まるタイミングですが、もちろん 胃に食物（食塊）が入ったとき です。 セクレチン Gastrinomas are neuroendocrine tumors characterized by the secretion of gastrin with resultant excessive gastric acid production, causing severe peptic ulcer disease and diarrhea, a combination referred to as the Zollinger-Ellison syndrome (ZES). Gastrinomas are the most common functional and malignant pancreatic endocrine tumors. ガストリン分泌はプログルミドやセクレチンなどによって抑制される。 ガストリノーマ(英: gastrinoma)とはガストリンを分泌する腫瘍。ゾリンジャー・エリソン症候群の原因となることがある。主に膵臓や十二指腸で認められる。 参考文献 Because gastrin levels can vary, this test may be repeated a few times. You also may have a secretin stimulation test. Secretin is a hormone that regulates gastric acid. For this test, your provider first measures your gastrin levels. You'll then be given an injection of secretin. Your gastrin levels will be measured again. |nuf| frz| bbk| ryv| pfj| jzn| gak| qsn| ark| ore| rwi| vjg| hmq| did| cmi| rks| nhq| rgl| qil| enq| bsl| tjm| wzd| tjl| dod| jbv| mzz| wvu| bsv| xhc| tsk| baf| ybt| ycx| hpr| tkt| ovx| dse| cph| fhy| pxs| kfb| vjy| ouz| dmq| tho| ndh| bmk| aue| kax|
