1.   Smooth muscle cells of the gastric body and antrum exhibit inherent rhythmic polarisation and depolarisation of the electrical potential across the cell membrane.

2.   Decreased peptic activity was present not only in the antral mucosa but also in the less affected mucosa of the gastric body.

3.   Images of the fed patterns after the ingestion of a test meal showed good separation of solid and liquid particulate matter and mixing waves in the gastric body.

4.   Antral crypts were estimated to be longer than gastric body crypts.

5.   The flow cytometrically derived S phase duration was similar in gastric body and antral cells.

6.   The allele frequency of the small fragment was significantly higher in patients with gastric body ulcer than in controls and in patients with gastric angular or antral ulcer.

7.   The genotypes which possessed the small fragment was significantly more frequent in patients with gastric body ulcer than in controls and in patients with gastric angular or antral ulcer.

8.   In order to gain a better appreciation of the genotypic risk, the relative risk of gastric body ulcer associated with the genotypes was estimated.
