Gastric mucosal defensive factor plays an important role in the pathogenesis of various gastric diseases as well as aggressive factor such as acid. Gastric mucosal defensive factor of various gastric diseases and the relation to acid secretion were studied. The influence of operative insult and obstructive jaundice on gastric aggressive and defensive factors was also studied. Defensive factor was investigated using gastric transrnucosal potential difference (PD). The results obtained were as follows :
1) PD showed low value in the gastric diseases with the mucosal lesion such as gastric ulcer, stress ulcer and bleeding gastric ulcer. Particularly the last two diseases, which had active mucosal bleeding, showed remarkably low values.
2) PD tended to increase following acid secretion but had no significance.
3) Operative insult seemed to cause transient increase of intragastric pH and deterioration of gastric defensive factor, and the change was enhanced by obstructive jaundice.
