Nasal hyperreactivity and neuropeptides

: The Authors define nasal-sinusal hyperreactivity and closely investigate the influence it has on the relationship existing among the Central Nervous System, Peripheric Nervous System, Immunitary System and Nasal Mucosa. Particular reference is made to neuropeptides that seem to be true "bridge" substances between the Nervous System and some components of the Immunitary System. Importance of the P-Substance is emphasized.
