Acute gastritis in cats. Effect of water lavage and local hypothermia on gastric blood flow.

In the present investigation gastric blood flow was determined in cat stomachs with acute inflammation during continuous local irrigation with ice water (4 degrees C) or water at body temperature (37 degrees C). Acute gastritis was induced by a 10% acetic acid solution and gastric mucosal and muscularis blood flow were measured by means of gamma-labelled microspheres. The mucosa and muscularis blood flow remained essentially unchanged during irrigation either with ice water or warm water during the observation time of 2 h. The difference in gastric blood flow between the ice-water and warm-water-irrigated groups was not significant.
