    Abstract:
    To investigate whether antral colonization by Helicobacter pylori (Hp) modifies gastrin-cell population, the number of G-cells was evaluated in antral biopsy specimens from 22 apparently healthy subjects and from 48 duodenal ulcer patients using a morphometric method. The level of serum immunoreactive gastrin in a sample of fasting serum obtained at the time of biopsy was also measured. In healthy subjects the G-cell count (evaluated according to G/I index) and the serum gastrin levels were not significantly different than those found in duodenal ulcer patients. When the antral colonization by Hp was assessed, we found that, both controls and duodenal ulcer Hp-positive patients had a mean G-cell count and fasting serum gastrin levels not significantly higher than in patients without Hp.
