Using a pH-sensitive radiotelemetering capsule with antimony electrode or glass electrode, the capacity of the gastric acid secretion was determined according to a modified Satveny's method on four healthy controls and 19 patients with peptic ulcer, and it was compared with that from the usual aspiration method. As to the basal condition, acid output couldn't be measured by the telemetering method in most cases because of high pH value in the stomach. There was no definite relation between two methods. On the other hand, acid output from the telemetering after stimulation of AOC-tetragastrin (4 gamma/kg, s.c.) showed a good reproducibility and good correlation with that from the aspiration method (r = +0.86). And the difference between two methods could be explained from the fact that some volume of secreted acid escaped into the duodenum before being neutralized by potassium bicarbonate, and that some of gastric juice remained not aspirated in the stomach.
使用带有锑电极或玻璃电极的pH敏感无线电遥测胶囊，根据改良的萨特维尼方法，对4名健康对照者和19名消化性溃疡患者的胃酸分泌量进行了测定，并与常规抽吸法的结果进行了比较。在基础状态下，由于胃内pH值较高，大多数情况下遥测法无法测量酸分泌量。两种方法之间没有明确的关系。另一方面，在注射四肽胃泌素（4微克/千克，皮下注射）刺激后，遥测法测得的酸分泌量具有良好的重复性，且与抽吸法测得的结果具有良好的相关性（r = +0.86）。两种方法之间的差异可以从以下事实来解释：一些分泌的酸在被碳酸氢钾中和之前就逸入十二指肠，并且胃内仍有一些胃液未被抽吸到。
