title: [Mucosal changes in the stomach of rats in the early stages of chronic renal failure].
abstract: In a series of chronic experiments on 30 rats subjected to nephrectomy, use was made of the present-day morphological and quantitative histochemical techniques to study the activity of oxidation-reduction enzymes, hydrolases and PAS-reaction in cellular elements of the mucous membrane of the fundal and antral parts of the stomach. It was found that in the early stages of experimental renal insufficiency, all the main cells of the glands manifested marked hyperplasia. These alterations seem likely to be adaptive in nature and are caused by the stimulatory action of the increased amounts of nitrous residue in the gastric lumen of such animals. The authors discuss the origin of gastric pathology in experimental animals and make clinical and experimental correlations.
