title: [Inhibition of gastric myoelectric activity and gastric motility induced by microinjection of substance P into caudate nucleus in mouse].
abstract: Changes of gastric myoelectric fast wave, slow wave and gastric motility were studied after microinjection of substance P or ACh into caudate nucleus in an attempt to find the interaction between the two substances. Gastric myoelectric activity and motility were recorded by a RM-6200 four channel recorder and then delivered to a IBM-PC computer for analysis. After microinjection of SP or ACh into caudate nucleus, the gastric myoelectric fast wave and gastric motility were significantly suppressed, while the slow wave was not significantly changed.
