AbstractCysteamine given three times within 8 h produced severe duodenal and gastric ulcers in female SIV rats. A pentobarbital anesthesia during the first 10 h prevented gastric ulcer formation without affecting duodenal ulcer. An additional 10 h lasting intragastric infusion with 0.6 ml/h Ringer containing 5 mmol/l of a mixture 3: 1 pure taurocholic and glycocholic acid or 20 and 50 mmol/l pure taurocholic acid in 0.2 N HCl did not reverse the protective effect of pentobarbital, e.g. incidence and intensity of gastric ulcer did not change. Treatment with somatostatin significantly reduced the intensity of duodenal ulcer. The inhibition of cysteamine-induced gastric ulcer formation by pentobarbital does not seem to be due to a possible inhibition of duodenogastric reflux but more likely to an inhibition of central nervous stress reactions by anesthesia.
