title: Effects of L-glutamine on various gastric lesions in rats and guinea pigs.
abstract: Effects of L-glutamine on gastric lesion models in rats and guinea pigs were studied. Shay ulceration in rats was not inhibited by oral L-glutamine. Although stress-induced gastric lesions in intact rats were not inhibited by L-glutamine, a strong antagonism of gastric lesions was induced in pylorus-ligated rats under the same stress by the amino acid. Histamine-induced gastric lesions in intact rats and guinea pigs were also markedly inhibited by L-glutamine. L-Glutamine inhibited the gastric lesions in rats induced by compound 48/80 but not significantly. Reserpine- or serotonin-induced gastric lesions in rats were not affected by L-glutamine. The mechanism of L-glutamine protection was discussed.
