title: [Effect of calcitonin, somatostatin and cimetidine on stress ulcer in rats].
abstract: The prophylactic effect of calcitonin, somatostatin and cimetidine on stress ulcer formation in rats was investigated in two stress models: restraint + ketamin (4 h) and hypovolemia (4 h). The basis of the comparative study was a 70% inhibition of acid secretion for 4 h in pyloric ligated animals. This was achieved with 1000 microgram/kg somatostatin s.c., 10 microgram/kg calcitonin s.c., and 2 X 100 mumol/kg cimetidine s.c. In restraint stress and ketamin with calcitonin and cimetidine a significantly lower frequency of gastric lesions was found than with somatostatin. The most potent substance in hypovolemia was calcitonin, with a significant difference in the frequency of mucosal lesions to the groups with cimetidine and somatostatin.
