Abstract

Considerable work has been done on the production of ulcers in the intestinal tract of the dog. The incidence of experimentally produced ulcers varies with the type of operative procedure employed. The Exalto and the Mann Williamson technic give the highest percentages of positive results. A detailed description of these methods was given in a previous report. The relative immunity of the duodenum toformation of ulcer by experimental methods is therein commented on.

The existence of ulcers in the gastrointestinal tract of the normal laboratory animal which has not been operated on is of rare occurrence; no particular attention is called to this in the literature. We determined, therefore, to make observations of the entire gastrointestinal tracts of apparently normal dogs and to determine the incidence of intestinal ulcers in these animals.

We have recently reported work from this laboratory on the production of experimental duodenal ulcers in the dog
