[Body nonspecific resistance in patients with gastric and duodenal peptic ulcer]

The present study focuses on bodily resistance to Helicobacter pylori infection. A decline is shown in factors of unspecific resistance, in particular, leucocyte content of non-enzymic cationic proteins in the phase of exacerbation of the ulcer process. Weakening of resistance is accompanied by a decline in the activity of phagocytosis. Thus, compromised antibacterial defence of the organism during the phase of exacerbation of the ulcer process contributes to the development of Helicobacter pylori in the gastroduodenal zone.
