Research Abstract

Mouse small intestine twitch in response to electrical field stimulation. The response were composed of two peaks, a fast peak which appears after ca. 1 sec and the second sloe peak which appears after ca. 2.5 sec. The amplitude of the second peak increased remarkably after the treatment of the intestinal preparation with staphyrococcal eneterotoxin A. Monoamine seemed to mediate the second peak but CPG activity in CNS of the crayfish which is reported to be mediated by monoamines showed no obvious change by the enterotoxin.
