1.   The H pylori negative and positive healthy volunteers were similar for both basal and peak acid output.

2.   Increased basal acid output and increased peak acid output are important features in patients with DU.

3.   Increased basal and peak acid output was also prevalent in the patients with idiopathic DU.

4.   The increased peak acid output to pentagastrin in the patients with idiopathic DU and H pylori positive patients with DU indicates that both have an increased parietal cell mass.

5.   Alcoholic beverages with low ethanol content and strong stimulants of gastric acid secretion and gastrin release, the effect of beer being equal to the maximal acid output.

6.   Atropine given during intravenous infusion led to an immediate fall in acid output.
