Abstrakt

The antral gastrin-producing cells (G-cells) have been identified by the indirect immunoperoxidase technique in two antrum preparations removed due to a recurrent duodenal and gastric ulcer. Morphometric principles were applied to the G-cells with determination of their volume density, numerical density, and mean cell volume. The study showed that within-observer variation, between-observer variation and within-patient variation were negligible, provided at least 200 G-cells were counted. A biopsy material can be used, as well as larger tissue blocks, when this minimum sample size is respected. A method for estimating the total G-cell population and the total G-cell volume in the antrum was developed. In the antrum removed due to a gastric ulcer the number of G-cells was 190 x 10(6) and their total volume 176 mm3.
