Abstract/OtherAbstract:
Using an antibody microprobe technique, we have detected substance P release from the region of the substantia gelatinosa of the cat during the first, but not the second, 30 min of topical application of capsaicin (1-3%) to the tibial nerve. Immunohistochemical analysis also showed that substance P-like immunoreactivity was markedly reduced in the superficial layer of the dorsal horn 30 min after application of capsaicin. These results indicate that substance P is released and then depleted from primary afferent central terminals following acute application of capsaicin to the peripheral sensory nerve.
