[Epitheliocytes of fundal glands and the relative volume of the parietal microflora of the stomach and small intestine mucosa in experimental chronic duodenal ulcer].

The effect of experimental chronic duodenal ulcers and vagotomy on fundal gland epitheliocytes and membrane microflora has been studied in rats using light microscopy and stereometry on semithin sections. It is shown that in ulcers the relative amount of perietal and zymogen cells increases, while the volume of mucocytes decreases. Vagotomy leads to a decrease in the relative amount of parietal and zymogen cells and increases the relative amount of mucocytes. The relative volume of membrane microflora in gastric fundal and pyloroantral regions, duodenum and jejunum diminishes in ulcers and increases in vagotomy, as compared to the control.
