The protein constituents in parasympathetically evoked saliva from normal and short-term sympathectomized parotid glands were compared. There was a reduction in all proline-rich proteins (PRP) in the saliva following sympathectomy. The decrease was quantified for acidic PRP by high-performance ion-exchange chromatography, which showed an increase in the ratio of amylase to other proteins. These results suggest that sympathetic impulses influence the synthesis of PRP and amylase in opposite directions.
