Helicobacter pylori eradication and antral intestinal metaplasia--two years follow-up study.

Intestinal metaplasia (IM) appears to be an important stage in the pathogenesis of intestinal type of gastric cancer. The purpose of the study was to evaluate how H. pylori eradication modifies IM in gastric antrum.

Procoagulant and fibrinolytic activities of gastric and colorectal cancer.

Procoagulant activity (PA) and fibrinolytic activity (FA) were investigated in 14 specimens of gastric cancer (GC) and in 26 specimens of colorectal cancer (CC) and simultaneously, in samples of the normal mucosa obtained from the same organs. Histochemical localization of plasminogen activator was performed at the tumor borderline. The PA of the tumor extracts was in most cases lower than in the corresponding normal mucosa from GC as well as CC patients.
