[Nitrergic structures in the spinal ganglia in rabbits].
Nitrergic structures in normal rabbit dorsal root ganglia (DRG) were demonstrated in this study. Histochemical reaction for detection of NADPH-d activity was used indicating, the presence of nitric oxide synthase (NOS). Diaphorase activity was found mostly in small ganglion cells. The cells defined as intermediate in size were stained less frequently, and no big cell expressed diaphorase activity. The intensity of staining varied from light blue and violet to very dark. The highest number of reactive cells was detected in the sacral DRG. Neurons expressed very low concentration of diaphorase activity in cervical, thoracic and lumbar DRGs. These findings suggest, that NADPH-diaphorase activity demonstrate a distinctive distribution depending upon spinal level.
