[Changes in the histamine content and morphology of the gastric mucosa in duodenal ulcer after pentagastrin stimulation].
A parallel study on histamine concentration and morphology of biopsy from gastric mucosa, was carried out with 60 patients with duodenal ulcer, prior to and post stimulation with pentagastrin--6 micrograms/kg. Histamine was spectrofluorimetrically determined. The functional-morphological changes that developed were followed up on 15, 30 and 60 min after the stimulation. They were a functional character and were due to disturbed microcirculation of the gastric mucosa: edema, venous stasis and leukopedesis. The latter were progressively increased within the course of 1 hour after the stimulation. The histamine-mobilizing effect of pentagastrin was manifested with a short-term decrease, followed by a considerable increase of histamine content in gastric mucosa of the patients with duodenal ulcer.
