[Possibility of Helicobacter pylori invasion into the lamina propria of the gastric mucosa].

Biopsies of the stomach antrum and fundus from 20 male patients with non-ulcer dyspepsia were studied light- and electron-microscopically. Helicobacter pylori infection was found in 60% of cases. In 2 patients, the bacteria were found not only in the fovea and mucus, but in the tunica propria as well. The bacteria were observed in the dilated intercellular spaces of the epithelium, between epithelium and basal membrane as well as around the glands and capillaries in the form of colonies. In the tunica propria the bacteria were represented mainly by the coccus forms, they had the signs of involution. There were signs of the bacterial influence on immunocompetent cells.
