Distribution, localization, and morphological peculiarities of NO-ergic nerve cells in the intestine of the snow sculpin Myoxocephalus brandti (Cottidae family) were studied using histochemical staining for NADPH-diaphorase ( NADPH-d). These cells were shown to be present in the pyloric appendages, middle and posterior parts of the intestine and in its rectal part. The NO-ergic cells are the most numerous in the myenteric plexus and circular muscle layer of all studied parts of the intestine. Single NO-ergic nerve cells are revealed in the submucosal plexus of pyloric appendages, middle and posterior parts of the intestine. No NO-ergic neural cells were found in subserosal and subepithelial plexuses, longitudinal layer of smooth muscle in all studied parts, and in the submucosal plexus of the rectal part of the intestine.
