Abstract
The clinical syndrome of stress ulceration has been studied for years using rodent cold restraint stress models, although the pathogenesis of the characteristic focal gastric mucosal lesions produced in these models has been controversial. We used gastric strain gauges to characterize fully the gastric motility effects of a 4-h cold restraint protocol, and we determined the relationship of variations in gastric contents and in gastric contractions to the amount of gastric mucosal injury. Additionally, we examined rat stomachs histologically, and determined the location of focal haemorrhagic mucosal lesions on the mucosal rugae. We found a consistent relationship between force of gastric contractions and gastric mucosal injury, and also a relationship between the initial duration of contractions during restraint and ultimate mucosal injury. Volume, acidity and mucus in the gastric contents were unrelated to mucosal injury. The majority (91%) of the mucosal lesions had some relationship to a rugal fold, with 59% of all lesions at the base of a rugal fold. Thus, the mechanical forces of gastric hypercontractility may contribute to the gastric mucosal injury of rodent cold restraint models.
