Gastric secretion (Gs) analysis during pentagastrin stimulation (a) and cola intake (b). (A) pH changes in gastric content. (C) Ca changes in gastric content. (E) Total phosphorus (Ptot) changes in gastric content. Duodenal secretion (Ds) changes before (time 0) and after cola intake. (B) pH changes in duodenal content. (D) Ca changes in duodenal content. (F) Ptot changes in duodenal content.

In addition, blood samples were obtained every 30 min over 180 min (Figure 1). In basal conditions, serum calcium, phosphorus, magnesium, sodium, potassium, chloride, glycemia, and urinary calcium and phosphorus were in the normal range (results not shown), as were the gastric and duodenal Ptot levels (Figure 1). A pentagastrin injection caused a slight decrease in pH after 5 min followed by an increase over 60 min (Figure 1). A slight change in gastric calcium and phosphorus was observed from 5 to 30 min after a pentagastrin injection, whereas a remarkable increase in Ptot level was observed after 60 min (Figure 1).
