Abstract:
The motor effects of DOPA and Dopamine on the isolated rat duodenum in vitro have been studied by establishing successive dose- response curves. These effects are either excitatory or inhibitory according to the concentrations used. In every case they are of small amplitude. The inhibitory effects do not exist in the presence of alpha, and beta blocking agents. The excitatory effects are suppressed by using a serotoninergic blocking agent.
