IN THE RESIDUAL STOMACH WITH A STOMAL ULCER THE NUMBER OF PARIETAL CELLS

Abstract

The number of parietal cells was estimated through endoscopic biopsy specimens taken from the upper greater curvature of the residual stomach with or without a stomal ulcer. A partially modified Hoshiko's method was used for the calculation of parietal cells. There was an apparent difference in the number of parietal cells depending on the association of ulcers. The calculated number of parietal cells in cases with stomal ulcer remained in the level of those in normal, not-operated stomach. On the contrary, the number of parietal cells in residual stomach without ulcer was significantly low. If the corrected number of parietal cell (length of parietal cell number of parietal cell) is used this difference becomes more apparent. MAO was measured and compared to the number of parietal cells. There was not a significant difference statistically between those two groups, though there was a tendency that the decrease of parietal cell function was less prominent in cases with on stomal ulcer.
