Аннотация
In order to investigate chronic hypergastrinaemia in dogs, studies with various excluded antrum preparations were performed. Gastric secretion was collected from denervated fundic pouches and gastrin levels were measured pre- and postoperatively by radioimmunoassay. In some samples the gastrins were separated according to their molecular size. Distinct hypergastrinaemia and acid hypersecretion developed in dogs where the antrum was excluded by a mucosal septum. Gastrin levels rose to 349 +/- 64 pg/ml (normal 76 +/- 19 pg/ml). Analysis of the gastrin pattern showed a predominance of smaller gastrin components. Although there was marked hypersecretion in most of the dogs with hypergastrinaemia, no close correlation was evident between these parameters. Some of the dogs with hypergastrinaemia developed anastomotic ulcers.
