title: Histochemical localization of nitric oxide synthase in the bullfrog intracardiac ganglion.
abstract: Histochemical and immunohistological methods have been used to demonstrate the presence of nitric oxide synthase (NOS) in the intracardiac parasympathetic ganglion of bullfrog heart. Both NADPH-diaphorase staining and indirect immunofluorescence with polyclonal antibodies raised against the C-terminal regions of a cloned NOS from rat cerebellum show that the postganglionic, parasympathetic neurons in the intracardiac ganglion contain NOS. This suggests that nitric oxide may have a role in neuronal activity in frog heart.
