Abstract A chronic delayed hypersensitivity reaction was produced in the pig stomach. In skin-sensitized animals 2–4 dinitrochlorobenzene (DNCB) in adhesive paste produced mucosal ulceration with intestinalization, edema, and marked round-cell infiltration of the submucosa, vascular congestion, perivascular cuffing, and fibrinoid arteriolar changes. When pigs that were not skin-sensitized were given DNCB in adhesive paste, no mucosal ulceration was seen. A similar but less intense cellular infiltrate and vascular change was present. Circulating antibodies to DNCB showed no relationship to the morphological lesion, while parietal cell antibody immunofluorescent titers parallel the intensity of the tissue response. Under the conditions of this experiment, parietal cell antibodies are not involved in the pathogenesis of the mucosal lesion.
