Summary
30 min after an intraperitoneal injection of reserpine (5 or 10 mg/kg) in the frog (Rana temporaria) and in the toad (Discoglossus pictus), a substance which has the properties of 5-hydroxytryptamine (argentaffine reaction, azoreaction, indoreaction and fluorescence in U.V. after formaldehyde) disappears from the skin glands; the histochemical reactions are more positive again 1 1/2 to 2 h after the injection of reserpine.
