Histochemical localization of nitric oxide synthase in the bullfrog intracardiac ganglion.
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.
