Abstract:
Objective To explore the role of the sensory neuropeptide in the chronic cough induced by postnasal drip syndrome(PNDs).Methods Patients of PNDs with and without chronic cough who came to the First Affiliated Hospital of Ji Nan University between Mar.2004 and Sep.2005 were enrolled and induced sputum by hypertonic saline aerosol inhalation was performed.Twenty-three cases of PNDs with chronic cough and 16 cases of PNDs without chronic cough were collected.Substance P(SP)and calcitonin gene-related peptide(CGRP)in the supernatant of the induced sputum were measured by radioimmunoassay.Results SP and CGRP in the supernatant of the induced sputum were significantly higher in the patients with chronic cough induced by PNDs[SP(345.14?72.58)mg/L,CGRP(573.78?210.96)mg/L]as compared with those normal subjects[SP(168.14?56.97)mg/L,CGRP(227.69?70.84)mg/L,P
