Effect of salicylates on cyclic AMP in isolated rat gastric mucosa

Studies on the cyclic AMP content of isolated rat gastric mucosa have been conducted with sodium salicylate and lysine-acetylsalicylate singly and combined with gastric secretagogues and their antagonists. Both salicylates at a concentration of 1.66 X 10(-2) M increased the amount of cyclic AMP. The increase of gastric mucosal cyclic AMP produced by sodium salicylate was diminished by prostaglandin E1 (10(-5) M), atropine (10(-6) M) and the H2-antihistamine metiamide (2 X 10(-4) M). Theophylline 3 X 10(-3) M), histamine (10(-3) M) and pentagastrin (10(-6) M) did not enhance the cyclic-AMP-response to salicylate or lysine-acetyl-salicylate.
