Abstract
The formaldehyde-induced fluorescence microscopy and microfluorimetry were applied to bullfrog sympathetic ganglia in order to examine the effect of reserpine on the cellular catecholamines in two types of cells [ganglion cells and small intensely fluorescent (SIF) cells]. The skin color of the bullfrog changed into dark from green and this change was observed on the second day after administration of reserpine. Reserpine-induced catecholamine fluorescence reduction was obtained dose-dependently in bullfrog sympathetic ganglion cells. But, a marked changes in the fluorescence intensity of SIF cells could not be observed.
