Abstract:
Objective The study was to explore the relationship between Helicobacter pylori ( H.pylori ) infection and aberrant mucin expression in gastric mucosa. Methods H.pylori infection was diagnosed by Warthin Starry staining method, and different kinds of mucin were detected using the immunohistochemical method. Results Positive staining of MUC2 mucin was found in 14 out of 21 patients with mucosa positive for H.pylori ( 66 7%), whereas only 6 cases showed MUC2 mucin expression in 18 H.pylori negative patients (33 3%) ( P 0 05). Conclusion H.pylori infection may alter the expression of some mucin genes in pericancerous gastric mucosa and destroy the gastric mucosa barrier
