title: Duodenal G- and D-cell changes following corticosteroid administration. Immunocytochemical long-term study in guinea pigs.
abstract: Prednisolone administration in guinea pigs for 20 days induces significant hypergastrinemia and duodenal G-cell hyperplasia. Hypergastrinemia and duodenal G-cell hyperplasia are less prominent following 40 days of prednisolone administration and this could be partly attributed to the duodenal D-cell increased activity, which represents an adaptive response to the alterations of gastric secretory functions induced by corticosteroids.
