The dose response of duodenal bicarbonate production during synthetic porcine secretin infusions was studied in six healthy volunteers and related to plasma secretin immunoreactivity. Secretin was infused in each individual at four different doses from 0-1 to 2-7 CU/kg/h, each infusion lasting for 60 minutes. Mean maximal bicarbonate secretion was 33 +/- 4 mEq/h. The secretin plasma level for half maximal bicarbonate response was estimated to be 22 pmol/l. As this level is reported to be achieved by intraduodenal acidification in man, it is concluded that secretin may well play a part in the control of duodenal pH.
在六名健康志愿者中研究了合成猪促胰液素输注期间十二指肠碳酸氢盐产生的剂量反应,并将其与血浆促胰液素免疫反应性相关联。向每个个体以0.1至2.7 CU/kg/h的四种不同剂量输注促胰液素,每次输注持续60分钟。平均最大碳酸氢盐分泌量为33±4 mEq/h。估计碳酸氢盐反应达到半数最大值时的促胰液素血浆水平为22 pmol/l。由于据报道在人体中十二指肠内酸化可达到这一水平,因此得出结论,促胰液素很可能在十二指肠pH值的控制中发挥作用。
