Abstract
The "gastric chamber" technique, performed in the anaesthetised rat, enables the study of gastric mucosal fragility induced by doses of phenylbutazone, which do not themselves cause ulceration or exulceration. The perfusion of buffered solution at pH 2-8 into the gastric chamber shows that prior oral administration of phenylbutazone 50 mg/kg increases the fragility of the mucosa. The optimal delay separating this administration from the time of experimentation is 6 hours. The effects seen are essentially vascular disorders.
