Abstract:
By means of NADPH-diaphorase (NADPH-d) histochemistry and nitric oxide synthase (NOS) immunohistochemistry, we demonstrate that considerable numbers of NADPH-d-positive neurons are distributed throughout the canine superior cervical ganglion (SCG). These neurons also show NOS immunoreactivity. This finding indicates that NADPH-d histochemistry, a simple and reliable technique, can be used as a reliable marker of NOS activity in the sympathetic innervation of canine head and neck. The present findings suggest that the participation of nitric oxide in the SCG differs greatly between species.
