胃酸分泌时,来自胃腺壁细胞的信号到达粘膜下层引起胃粘膜血流增加,但给予5肽促胃液素促进胃酸分泌时并不能使血流增加呈平行反应,表明在一定条件下胃酸分泌和胃粘膜血流之间的变化可以相互分离.近年来内皮来源的舒血管物质 NO 在调节胃粘膜微循环中起重要生理作用,但关于胃内生理性刺激因素胃扩张引起胃酸分泌过程中 NO 对胃粘膜
Gastric acid secretion, the signal from the gastric gland parietal cells to reach the submucosa caused gastric mucosal blood flow increased, but to give 5 peptide gastrin to promote gastric acid secretion does not make the blood flow increased parallel reaction showed that under certain conditions, gastric acid secretion and stomach Mucosal blood flow changes can be separated from each other in recent years, endothelium-derived vasodilator NO in the regulation of gastric mucosal microcirculation play an important physiological role, but on the physiological stimuli in the stomach due to gastric distension caused by gastric acid secretion of NO to the stomach Mucosa
