Axoplasmic transport of somatostatin and substance P in the vagus nerve of the rat, guinea pig and cat
The axoplasmic transport of somatostatin (SS) and substance P (SP) in the cervical vagus nerve was studied in the rat, guinea pig and cat. In preliminary research, neuropeptide immunoreactivity (IR-SS and IR-SP) was evaluated in extracts of nodose ganglion and vagus nerve utilizing gel and reverse-phase high-performance liquid chromatography (HPLC). In every species, a single immunoreactive type of SP co-eluted with the artificial...
