The aim of this study was to localize the distribution of (reduced) nicotinamide-adenine dinucleotide phosphate (NADPH) diaphorase-positive nerves in the rat nasal mucosa by NADPH diaphorase histochemistry, and to determine its origin by utilizing retrograde tracing with Fluoro-Gold (FG). Fine varicosities of NADPH diaphorase-positive nerve fibers were distributed around blood vessels (arterioles in particular), submucosal glands, and the subepithelial layer of the nasal mucosa. Most of the ganglion cells and nerve fibers in the sphenopalatine ganglion, and a few ganglion cells in the trigeminal ganglion, were stained by NADPH diaphorase, but no NADPH diaphorase-positive ganglion cells were ...
