Stroma-parenchymal relationships in gastric ulcer and cancer operatory specimens.

A quantitative analysis of relationships between stroma and parenchyma was performed in 30 cases of antral gastric ulcer, 30 cases of operated duodenal ulcer and 30 cases of operated gastric carcinoma; as controls there were used stomach specimens from three healthy youths, aged 20-22 years, dead in traffic accidents. Morphometric and gravimetric methods were used. In the deep layers of the gastric mucosa, the quantitative estimation generally inclines in favour of the parenchyma (accompanying gastritis), in the normal mucosa the gravimetric ratio is maintained close to the unit, and the cell count reveals predominance of the parenchyma.
