Abstract

The transmural stimulation caused relaxation of atropinized taenia strip from chimpanzee and pig. This relaxing response was not blocked by adrenergic blocking agent (bretylium) but abolished by tetrodotoxin. From this fact, it seems reasonable to assume the presence of non-adrenergic inhibitory nerve system in taeniae of the chimpanzee and pig.
