The nitroxidergic components in the nervous system of Opisthorchis felineus, Paramphistomum cervi, Fasciola hepatica have been examined using histochemical nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) method. The NADPH-d positive staining occurs in the brain ganglia, brain commissure, longitudinal chords, among the muscle fibers of abdominal and oral suckers. The nitroxidergic structures which probably correspond to location of papillae are observed in suckers. The received results suggest the important role of nitric oxide in trematodes - Opisthorchis felineus, Paramphistomum cervi, Fasciola hepatica.
