The purpose of this study is to determine whether or not proglumide has a preventive effect on the erosive gastritis induced by sodium salt of taurocholic acid (TCA) in the rat. Its effect on the formation of gastric erosions, serum gastrin levels and secretion of acid and pepsin were also studied.
The rats were given standard feed containing 0.25% proglumide and water containing 5mM TCA (experimental E group). The control rats were given standard feed and water containing 5mM TCA (TCA group). All rats were killed at the end of the 3 months. The tissue specimens of the resected gastric mucosa were stained with hematoxylin eosin for histopathology and with azan for evaluation of fibrous ploriferation.
From microscopic observation of the stained specimens, the following results were obtained. TCA-group showed long mucosal surface injury (erosion), inflammatory cell infiltration, a reduction in the number of parietal cells, a decrease of mucosal thickness, and proliferation of collagenous fiber. In contrast, in the E group, these morphological and morphoquantitative changes were significantly small. The length of erosion and inflammatory cell infiltration were significantly reduced in the E group when compared with the TCA group. Furthermore, mucosal thickness was almost normal and fibrous proliferation was significantly scarce in the E group.
Proglumide had an insignificant effect on pH on the mucosa, volume and pH of gastric juice, serum gastrin levels and tetragastrin-induced secretion of acid and pepsin.
It is, thus, evident that proglumide has a preventive effect on the induction of erosive gastritis caused by TCA in the rats. Since it is difficult to explain its mechanism for the prevention of gastritis from only the already known facts that it has protective action on gastric mucosa and an inhibitory effect on secretion of acid and pepsin, unknown mechanisms are suspected to be involved.
