Zusammenfassung
Nitric oxide synthase activity was studied by means of NADPH-diaphorase activity and
nitric oxide synthase immunoreactivity in the main and accessory olfactory bulbs of the
frog Rana perezi and the newt Triturus marmoratus. In both species, NADPH-diaphorase
staining was observed in all olfactory fibers. Vomeronasal fibers were NADPH-diaphorase labeled in Triturus but they were NADPH-diaphorase negative in Rana. Nitric
oxide synthase immunoreactivity was not observed in the primary afferents in any case.Granule cells were NADPH-diaphorase positive and nitric oxide synthase immunopositive in the main and accessory olfactory bulb of Rana, and in the main olfactory bulb of Triturus. The homogeneous NADPH-diaphorase staining of olfactory fibers is similar to what has been reported in teleosts, and it contrasts with the spatial segregation of NADPH-diaphorase positive and negative olfactory projections in rodents. These results confirm the interspecies variability of the NADPH-diaphorase/nitric oxide synthase distribution in the olfactory system of vertebrates.
