1. The effect of neurotensin was studied in the isolated smooth muscle of the chicken crop. 2. This peptide induced concentration-dependent (10(-10)-10(-8) mol/l) contractions of muscle strips. 3. The response to neurotensin was not modified after incubation of the preparation with atropine, indomethacin, naloxone and tetrodotoxin. The neurotensin-exerted contractions are therefore probably myogenic. 4. These properties of neurotensin indicate a possible role for this peptide in the control of crop motility.
