[The action of thyroliberin on the myoelectric activity of the stomach in the skate and the cod].
The influence of exogenous thyrotropin-releasing hormone on the myoelectrical activity of stomach was investigated in skate and cod. The i.v. or intracerebral application of the peptide (5-8-10 micrograms/kg) led to an increase in the amplitude of the stomach cardiac and pyloric potentials, and to a change in their rate. The effect lasted longer following intracerebral administration of the peptide and was abolished by vagotomy. Irrespective of the technique of the administration, the peptide effect on the stomach myoelectrical activity was abolished by atropine and not affected by phentolamine or propranolol.
