[Dose-effect relationship of glucagon on the stomach, pylorus and duodenum].

The effect of glucagon on the stomach, pylorus and duodenum was evaluated within the first 30 minutes p.i. Glucagon was administered intravenously in a dose of 0.1, 0.2, 0.4, 0.6 and 1 mg. The hypotonic effect was greater on the duodenum than on the stomach. The dose response of the pylorus was not uniform. It was possible to point out a direct relationship between the intensity and duration of the hypotonic effect and the administered dosage.
