title: On a possible new intracellular signal-system in rat gastric mucosa.
abstract: It is known that cAMP and cGMP, as an "intracellular second messenger system" play a significant role as a signal system, in the mechanism of action of anti-ulcerogenic (cytoprotective) drugs. According to our present, preliminary investigations it seems that during different experimental circumstances the gastric mucosal 3'-5'-cyclic-cytidine-mono-phosphate (cCMP) 3'-5'-cyclic-uridine-monophosphate and (cUMP) levels were changed--similarly to CAMP and cGMP--and these changes might be a possible indicator of a further, most probably secondary, signal- system role.
