Abstract
Substance P-like immunoreactivity cellular in toad sympathetic ganglia was studied in normal and capsaicin-treated ganglia. In the eighth sympathetic ganglion substance P-like immunoreactive are found in mast cells and SIF cells. The effect of substance P (0.001-0.003 mM) caused increase of compound action potential during tetanical stimulation (50 Hz by 40 sec.) and post-tetanic potentiation (0.1 Hz). Our results show that substance P facilitates synaptic transmission in the sympathetic ganglia from Caudiverbera caudiverbera.
