title: Cyclic nucleotide levels of nasal secretions in allergic patients and control subjects.
abstract: Cyclic nucleotides (CND) levels of nasal secretions were studied in allergic rhinitis patients and control subjects. In methacholine-induced nasal secretion, allergic rhinitis patients had lower cAMP levels, higher cGMP levels and a lower cAMP/cGMP ratio than the control subjects. A close relationship was found between CND levels and the severity of daily symptoms in both methacholine-induced and antigen-induced nasal secretions.
