title: [Determination of serum calicotonin gene-related peptide in patients with duodenal ulcer infected with Helicobacter pylori].
abstract: OBJECTIVE
  To investigate the effect of calicotonin gene-related peptide(CGRP) on duodenal ulcer caused by Helicobacter pylori infection.
  
  
  METHODS
  The serum levels of CGRP were determined by radioimmunoassay in 30 patients with duodenal ulcer associated with Helicobacter pylori infection and 20 healthy volunteers.
  
  
  RESULTS
  The mean CGRP serum level was higher in duodenal ulcer associated with Helicobacter pylori group than that in the healthy group.
  
  
  CONCLUSIONS
  The CGRP level might be one of the important factors in which Helicobacter pylori infections induce duodenal ulcer.
