[Estimation of gastrin in human gastric juice].

Concentration of gastrin was estimated in the stomach contents using a radioimmunoassay following careful collection and conservation of gastric juice. Debit of gastrin and the rate of its secretion are the most informative patterns as compared with estimation of the hormone content in the juice. The estimation of gastrin might be important both in studies of pathogenesis of stomach diseases and of mechanisms of drug action in treatment of the diseases.
