Abstract
The effect on gastric epithelial cell proliferation of a short-term, low-dose treatment with aspirin was evaluated in 9 healthy volunteers. Nine days before and during aspirin administration, the subjects assumed sulglycotide, a sulfated glycopeptide with cytoprotective properties. Endoscopic biopsies were collected in each subject from the gastric body and antrum before and after treatment. The specimens were incubated in a culture medium containing bromodeoxyuridine (BrdU). The proliferative activity was evaluated by immunohistochemical detection of BrdU uptake. A decrease in BrdU-labelled cells together with a shortening of the length of gastric columns were observed after treatment with aspirin and placebo in biopsies of both body and antrum (p
