Induction of heat-shock protein 72 protects against ischemia/reperfusion in rat small intestine.

abstract：:Ornithine decarboxylase activity is known to be increased in certain premalignant conditions. We determined the activity of this enzyme in mucosal biopsy specimens from 15 patients with Barrett's esophagus. Ornithine decarboxylase was greater in Barrett's mucosa than in squamous esophageal or gastric mucosa. In Barret...
