标题：INHIBITORY EFFECTS OF UNSATURATED FATTY ACIDS OF trans-2-C10 : 1 TO trans-2-C16 : 1 SEVERAL C18 : n AND C20 : n ON GASTRIC SECRETION AND EXPERIMENTAL ULCERATION IN RATS
摘要：Among various unsaturated fatty acids which were examined in this experiment, trans-2-tridecenoic acid was found to be a potent inhibitor on gastric secretion in rats (i.p. or i.d.). Therefore, the effects of trans-2-tridecenoic acid on several experimental ulcerations in rats were examined. At the dose of 10 mg/kg, trans-2-tridecenoic acid significantly decreased the ulcer index in pylorus-ligated rats; aspirin-, phenylbutazone-, histamine- and stress-induced ulcerations were also significantly inhibited at the dose of 25 mg/kg. Finally, effects of trans-2-tridecenoic acid on hexosamine and sialic acid contents in the gastric mucous were examined. In intact or phenylbutazone-induced ulcerated rats, trans-2-tridecenoic acid increased the sialic acid levels in the gastric mucous at the dose of 25 mg/kg. The decreased hexosamine content in the gastric mucous by phenylbutazone treatment was recovered by the administration of trans-2-tridecenoic acid.
