[Gastrin: recent points of view (author's transl)].

In a short survey recent results of research on gastrin are presented. Special stress is laid upon the mechanism of liberating gastrin, the role of the vagus in this process and the consequences of gastric surgery on serumgastrin. In clinical practice the differential diagnosis of hypergastrinemia in ulcer disease is very important, for it will have a decisive influence on the therapeutic decisions and the specific kind of surgical treatment.
