[The potentiation of stimulated gastric juice secretion by prednisolone]

In 5 series of dogs the acute effect of a high dose of prednisolone (40 mg/kg i.v.) on Histalog stimulated gastric secretion (5 mg/kg s.c.) was tested. There was no effect of prednisolone alone. The combination of Histalog and prednisolone showed a potentiation of Histalog stimulation in high range. The effect was not seen when truncal vagotomy was performed before stimulation. It is possible that there is a cholinergic reaction or an interaction in the metabolism of histamine.
