sensitive radioimmunoassays for calcitonin gene-related peptide and the tachykinin , neurokinin a , have been used to show that acute administration of the sensory neurotoxin capsaicin ( 10 mg/kg i.p . ) to normal adult rats , causes a substantial release of calcitonin gene-related peptide immunoreactivity ( 15-fold increase ) and neurokinin a immunoreactivity ( 4- to 5-fold increase ) into the plasma .
